    Palaeontology: Ice core evidence suggests famine worsened Black Death

    When the Black Death swept through Europe in 1347, it was one of the deadliest disease outbreaks in human history, eventually killing between a third and half of Europeans.

    Prior work by investigators has traced the cause to plague-carrying fleas borne by rats that jumped ship in trading ports. In addition, historical researchers believe that famine in northern Europe before the plague came ashore may have weakened the population there and set the stage for its devastation.

    Now, new research using a unique combination of ice-core data and written historical records indicates that the cool, wet weather blamed for the northern European famine actually affected a much wider area over a much longer period. The work, which researchers say is preliminary, paints a picture of a deep, prolonged food shortage in the years leading to the Black Death.

    “The evidence indicates that the famine was a broader phenomenon, geographically and chronologically,” said Alexander More, a postdoctoral fellow in the Harvard History Department and a lecturer in the History of Science Department.

    A widespread famine that weakened the population over decades could help explain the Black Death’s particularly high mortality. Over four or five years after arriving in Europe in 1347, the pandemic surged through the continent in waves that killed millions.

    The ice-core data is part of a unique program linking traditional historical research with scientific data-collecting techniques. The program, called the Initiative for the Science of the Human Past at Harvard (SoHP), is headed by Michael McCormick, the Francis Goelet Professor of Medieval History. SoHP’s ice-core project is being conducted in collaboration with the University of Maine’s Climate Change Institute and researchers at Heidelberg University. The project’s approach puts it at the juncture of environmental science, archaeology, and history. It is supported by the Arcadia Fund of London.

    More presented his findings at a conference in November arranged to discuss the project. Joining him was Harvard junior Matthew Luongo, an Earth sciences and environmental engineering concentrator from Dunster House, who discussed the discovery of volcanic tephra in the ice core. Tephra, microscopic airborne volcanic particles, are generally believed absent from cores in European glaciers, make Luongo’s assumption-puncturing discovery potentially significant.

    Luongo spent several days at the Climate Change Institute last summer performing chemical analyses and examining the volcanic bits through a scanning electron microscope. Each volcanic eruption has a slightly different chemical fingerprint, so he was able to trace the tephra to the 1875 Askja eruption in Iceland, one of the largest eruptions there in history.

    Since many eruptions were written about contemporaneously, the ice core’s volcanic traces can be used to align ice-core data with written records, providing greater certainty in dating other chemical traces in the ice, such as those from human activities like lead from Roman-era smelting.

    “I think it was a really important project,” Luongo said.

    McCormick said that the advanced technologies scientists used to understand areas like the human genome and climate change are increasingly being applied to the humanities, and opening new avenues of investigation.

    McCormick was part of a team that in 2011 used tree-ring data to reconstruct European climate over the last 2,500 years, showing that the period before the fall of the Roman Empire was marked by wide climactic variability. In November, McCormick summed up the use of climate data in historical research as reading history “from the environment itself.”

    “All these things are happening in the sciences and spilling over into the humanities,” McCormick said. “Twenty years ago, if you’d have told me that climate could have caused the collapse of the Roman Empire and that we would have the means to test that, I wouldn’t have believed you.”

    The new data emerging from the ice core could be the first of a flood of information about the last millennium and beyond. McCormick’s University of Maine colleagues, led by Paul Mayewski, have developed a laser-based method of ice analysis. It requires far smaller samples of ice and can take 50,000 samples in a one-meter ice core, compared with just 100 in the previous method. The new technology allows much higher resolution analysis of even very thin ice layers — to the specific year and potentially to individual storms — and can go back farther than the 1500 A.D. limit of this glacier with previous techniques.

    The ice core was the first ever taken specifically for historical research, McCormick said, and was drilled in 2013 from the Colle Gnifetti glacier, high in the Alps near the Swiss-Italian border. It was divided between partner organizations, with the portion allocated to the Initiative for the Science of the Human Past and the Climate Change Institute being held at the University of Maine.

    The findings about the period preceding the Black Death described by More continue to fill in an emerging and newly complex picture of a key period in human history. Recent research has traced the genesis of the European plague to animal groups in Asia and climate-related outbreaks that traveled along Silk Road trade routes.

    McCormick said this application of scientific methods opens new avenues of inquiry, akin to discovering colossal collections of historical records, whether read directly from the DNA of ancient people, from the trees that grew at the time, or from the ice deposited in ancient storms.

    “It’s a gigantic set of archives that document the least-documented part of [history],” McCormick said. “It’s kind of a renaissance of history.”

  • Mauritius: Dodos might have been quite intelligent, new research finds

    Mauritius: Dodos might have been quite intelligent, new research finds

    New research suggests that the dodo, an extinct bird whose name has entered popular culture as a symbol of stupidity, was actually fairly smart. The work, published in the Zoological Journal of the Linnean Society, finds that the overall size of the dodo's brain in relation to its body size was on par with its closest living relatives: pigeons--birds whose ability to be trained implies a moderate level of intelligence. The researchers also discovered that the dodo had an enlarged olfactory bulb -- the part of the brain responsible for smelling -- an uncharacteristic trait for birds, which usually concentrate their brainpower into eyesight.

    The dodo (Raphus cucullatus) was a large, flightless bird that lived on the island of Mauritius in the Indian Ocean. They were last seen in 1662.

    "When the island was discovered in the late 1500s, the dodos living there had no fear of humans and they were herded onto boats and used as fresh meat for sailors," said Eugenia Gold, the lead author of the paper, a research associate and recent graduate of the American Museum of Natural History's Richard Gilder Graduate School, and an instructor in the Department of Anatomical Sciences at Stony Brook University. "Because of that behavior and invasive species that were introduced to the island, they disappeared in less than 100 years after humans arrived. Today, they are almost exclusively known for becoming extinct, and I think that's why we've given them this reputation of being dumb."

    Even though the birds have become an example of oddity, obsolescence, stupidity, and extinction, and have been featured in popular stories ranging from Alice in Wonderland to Ice Age, most aspects of the dodo's biology are still unknown. This is partly because dodo specimens are extremely rare, having disappeared during the nascent stage of natural history collections.

    To examine the brain of the dodo, Gold tracked down a well-preserved skull from the collections of the Natural History Museum, London, and imaged it there with high-resolution computed tomography (CT) scanning. In the American Museum of Natural History's Microscopy and Imaging Facility, she also CT-scanned the skulls of seven species of pigeons -- ranging from the common pigeon found on city streets, Columba livia, to more exotic varieties. Out of these scans, Gold built virtual brain endocasts to determine the overall brain size as well as the size of various structures. Gold's colleagues at the Natural History Museum of Denmark and National Museum of Scotland sent her the endocast for the dodo's closest relative, the extinct island-dwelling bird Rodrigues solitaire (Pezophaps solitaria).

    When comparing the size of the birds' brains to their body sizes, Gold and collaborators found that the dodo was "right on the line."

    "It's not impressively large or impressively small -- it's exactly the size you would predict it to be for its body size," Gold said. "So if you take brain size as a proxy for intelligence, dodos probably had a similar intelligence level to pigeons. Of course, there's more to intelligence than just overall brain size, but this gives us a basic measure."

    The study also revealed that both the dodo and the Rodrigues solitaire, which recently was driven to extinction by human activity, had large and differentiated olfactory bulbs. In general, birds depend much more on sight rather than smell to navigate through their world, and as a result, they tend to have larger optic lobes than olfactory bulbs. The authors suggest that, because dodos and solitaires were ground-dwellers, they relied on smell to find food, which might have included fruit, small land vertebrates, and marine animals like shellfish.

    "It is really amazing what new technologies can bring to old museum specimens," said co-author Mark Norell, Macaulay Curator of Paleontology and Chair of the Division of Paleontology at the American Museum of Natural History. "This really underscores the need for the maintenance and growth of natural history collections, because who knows what's next."

    The researchers also discovered an unusual curvature of the dodo's semicircular canal -- the balance organs located in the ear. But as of yet, there's not a good hypothesis for this atypical feature.

  • Nigeria: The British Museum distorts history and denies its racist past

    Nigeria: The British Museum distorts history and denies its racist past

    The British Museum in London is rewriting history to appear in a better light and defend itself against demands to return objects to their countries of origin. This is the conclusion of a new PhD thesis in archaeology from the University of Gothenburg.

    “Manipulation of the past is not a new phenomenon. The most infamous examples of this can be found in the ways totalitarian states often record their history, like when the Soviet government retouched photos in order to remove persons who had become undesirable. But that museums revise their own history in a similar way has never been documented before,” says Staffan Lundén, author of the thesis.

    The study looks at the British Museum’s representation of the so-called Benin Bronzes. The objects became known in Europe after the Britons conquered and looted Benin City in present-day Nigeria in 1897. Many of them ended up at the British Museum, and today some of them belong to the most well-known objects in the museum’s collection. They have come to play a key role in the discussion on who owns the cultural objects that were looted from various countries during colonial times.

    The British Museum’s version unfounded

    Today the museum promotes the view that the Western world’s discovery of the sophisticated Benin Bronzes helped change the prevailing view of Africans as inferior. The museum’s own scholars are assigned critical roles in the important discovery that the objects indeed were of African origin and not the result of external influences.

    “Nobody has ever looked closer at whether the museum’s story is true. My review of the scholarly texts about the Benin objects that were published in the early 1900s shows that the British Museum’s representation of history is completely unfounded.”

    The source material, which also includes other publications from the museum, mainly guide books, instead reveals that the museum for a long time promoted a hierarchical view of the world that held Western culture as superior. The scholars at the museum who in the early 1900s wrote about the Benin objects claimed that they were a result of Portuguese influences.

    Legitimised derogatory stereotypes

    Lundén’s research also shows that the museum’s scholars did not help change the view of Africans. Instead they spread and gave scientific legitimisation to the stock stereotypes of Africans, such as the likening of Blacks to apes.

    “It’s remarkable that the museum’s so-called information about itself and the history of the Benin objects is totally contradicted by the source material. The study shows that the views conveyed by the museum are strongly characterised by wishful thinking, by the museum’s own traditions and by Western cultural values.”

    “Reason to be critical”

    The museum’s need for arguments against the return of objects is a strong driver of its rewriting of history and glorification of its past. According to Neil MacGregor, director of the museum until last year, the Benin objects exemplify how the British Museum ever since its opening in 1753 has promoted tolerance and respect for cultural differences. Thus, he that the objects provide a ‘key argument’ against the return of objects in the museum’s collections.

    Paradoxically, Lundén concludes, while the statement of objectivity and impartiality is central to the museum’s defence against the return of objects, it seems that the ownership issue strongly contributes to the biases in its representations.

    “The public tends to hold museums in high regard. They are considered trustworthy sources of impartial and scientifically based information. This is particularly true for big and well-known museums like the British Museum. But there’s definitely reason to be critical of the knowledge they convey,” he says.

    About the Benin Bronzes

    Benin Bronzes is the most common name for the objects looted from Benin City in 1897, but they were executed in many different materials: brass, bronze, coral, ivory, coral, terracotta, textile, wood etc. They are dated to the period from the late 15th century to the 19th century and were used for a variety of political and ritualistic purposes in the Benin kingdom. Some objects were placed on altars, some were used in ceremonies and others were wall decorations in a former royal palace.

  • Geology: Common magnetic mineral is reliable witness to Earth's history

    Geology: Common magnetic mineral is reliable witness to Earth's history

    Magnetic nanovortices in magnetite minerals are reliable witnesses of the earth's history, as revealed by the first high-resolution studies of these structures undertaken by scientists from Germany and the United Kingdom. The magnetic structures are built during the cooling of molten rock and reflect the earth's magnetic field at the time of their formation. The vortices are unexpectedly resilient to temperature fluctuations, as electron holographic experiments in Julich have verified. These results are an important step in improving our understanding of the history of the earth's magnetic field, its core and plate tectonics.

    The earth's magnetic field performs important functions: it protects us, for example, from charged particles from space and enables migratory birds, bees, and other animals to navigate. However, it is not stable, and constantly changes its intensity and state. Several times in the past it has even reversed its polarity -- the north and south poles have changed places.

    Scientists in the area of paleomagnetism use magnetic minerals to investigate the history of the earth's magnetic field and its formation from molten metal flowing within the earth's core, the so-called geodynamo. Furthermore, the movement of continental plates can be monitored with the aid of such rocks.

    In the course of millions of years, these minerals could often have been exposed to immense temperature fluctuations, due to extreme climate change or volcanic activity, for instance. How well do the magnetic structures survive such temperature fluctuations and how reliable is the information gained from them?

    An international research team has now studied this question for the first time at ultra-high resolution on samples of magnetite, the mineral dominating the magnetic properties in the earth's crust.

    "It is only in a small part of naturally occurring magnetite that magnetic structures known for being very stable with respect to temperature fluctuations are found," explains Dr. Trevor Almeida of Imperial College London. "Far more common are tiny magnetic vortices. Their stability could not be demonstrated until now."

    Together with colleagues from Forschungszentrum Julich, the University of Edinburgh and the University of Nottingham, Almeida has studied the magnetic vortices in magnetite nanocrystals. As the structures are so tiny -- each grain is only about the size of a virus -- there is only one method with which the nanovortices can directly be observed while they are heated up and cooled down: "A special high-resolution electron microscope at the Ernst Ruska-Centre (ER-C) in Julich is capable of making magnetic fields on the nanoscale holographically visible," explains Almeida. "In this way, images of field lines are produced almost like using iron filings around a bar magnet to make its magnetic field visible, but with a resolution in the nanometre range."

    The experiments in Julich showed that although the magnetic vortices alter in strength and direction when heated up, they go back to their original state as they cool down. "Therefore magnetite rocks, which carry signs of temperature fluctuations, are indeed a reliable source of information about the history of the earth," enthuses Almeida.

    "Electron holography has made it possible for us to gain a completely new insight into the magnetic behaviour of magnetite," emphasized Prof. Rafal Dunin-Borkowski, Director at the ER-C and at the Peter Grunberg Institute in Julich.

    As an expert in electron holography, he works with his Julich team on further improving the resolution of this technique and in providing German and international scientists the necessary infrastructure to perform this type of study.

    "Weak magnetic fields in nanocrystals don't just play a role in paleomagnetism. In information technology, for instance, electron holograms can also be of use to help to push back the physical limits of data storage and processing."

    The study has been published in Science Advances.

  • Environment: Not so crowded house? New findings on global species richness

    Environment: Not so crowded house? New findings on global species richness

    Planet Earth may contain millions fewer species than previously thought and estimates are converging, according to research led by Griffith University.

    fewer types of terrestrial arthropods than calculated in 1980s

    In a paper published by the journal Proceedings of the National Academy of Sciences (PNAS), Professor Nigel Stork of Griffith’s Environmental Futures Research Institute reveals findings that narrow global species estimates for beetles, insects and terrestrial arthropods.

    The research features an entirely new method of species calculation derived from samples of beetles from the comprehensive collection at London’s Natural History Museum.

    “It has been said we don’t know to the nearest order of magnitude just how many species with which we share the planet. Some say it could be as low as two million; others suggest up to 100 million,” says Professor Stork.

    “By narrowing down how many species exist within the largest group – the insects and other arthropods — we are now in a position to try to improve estimates for all species, including plants, fungi and vertebrates.

    “Understanding how many species there are and how many there might have been is critical to understanding how much humans have impacted biodiversity and whether we are at the start of, or even in the middle of, an extinction crisis.”

    About 25 per cent of all species that have been described are beetles. However, when combined with other insects the figure climbs to more than half of all described and named species on Earth.

    New method of estimation

    For this reason, Professor Stork and his colleagues focused on asking how many species of beetles and insects there actually are, in the process applying a new method of estimation arising from a tendency for larger species of British beetles to be described before smaller species.

    “Because of the global spread of major beetle lineages, we made the assumption that the size distribution of the very well known British beetles might be similar to that of beetles worldwide,” says Professor Stork.

    “So, if we could get a measurement of the body sizes of the beetles from around the world, we might be able to plot where these fitted in time against the British beetles.”

    After measuring a sample from the Natural History Museum’s worldwide collection of beetles, Professor Stork compared the mean body size with the changing body sizes of British beetles to reveal that roughly 10 per cent of the world’s beetles have been named and described.

    This figure sheds intriguing light on previous estimates of global species richness.

    In the 1980s, there were just two methods of estimating species. In the case of beetles, these gave a mean of 17.5 million species and a range of 4.9-40.7 million. For all terrestrial arthropods, the mean was 36.8 million and a range of 7-80 million.

    However, the new research shows that four current methods of estimation – dating from 2001 onwards — suggest much lower figures, namely a mean of 1.5 million for beetles (range 0.9-2.1 million) and 6.8 million for terrestrial arthropods (range 5.9-7.8 million).

    “While all methods of estimating global species richness make assumptions, what is important here is that four largely unrelated methods, including the new body size method, produce similar estimates,” says Professor Stork.

    “With estimates converging in this way, this suggests we are closer to finding the real numbers than before.

    “It also means we can improve regional species richness. For Australian fauna and flora, for example, we should be able to make better estimates of just how many species there are and which groups need more taxonomic attention.”

    Diversity of life

    Professor Ian Owens, Director of Science at the Natural History Museum, says this research is a great example of how natural history collections support high-impact scientific research that addresses challenging questions such as the diversity of life.

    “The Natural History Museum’s beetle collection is one of the most important and extensive in the world, so I’m delighted that it has played such a fundamental part in this study that uses a novel approach to estimating how many species of beetle exist,” says Professor Owens.

    “The results are very exciting and are a big step forward to establishing a baseline for biodiversity.”

    Meanwhile, co-author of the PNAS paper — the University of Melbourne’s Associate Professor Andrew Hamilton – says efforts to come up with new or modified ways of resolving how many species exist are beginning to prove fruitful.

    Professor Stork says the research has important conservation ramifications.

    “Success in planning for conservation and adopting remedial management actions can only be achieved if we know what species there are, how many need protection and where,” he says. “Otherwise, we have no baseline against which to measure our successes.

    “Furthermore, it is arguably not only the final number of species that is important, but what we discover about biodiversity in the process.

    “The degree to which we can or cannot accurately estimate the number of species or the scale of organismal diversity on Earth is a measure of our ignorance in understanding the ecological and evolutionary forces that create and maintain the biodiversity on our planet.

    “Attacking this question also drives scientific enquiry and is of public interest. Society expects science to know what species exist on Earth, as it expects science to discover nuclear particles and molecules.

    “These discoveries open doors to more utilitarian interests.”

  • Travel: 'Indigenous Australia: Enduring Civilisation' at the British Museum

    Travel: 'Indigenous Australia: Enduring Civilisation' at the British Museum

    The British Museum will open a major exhibition presenting a history of Indigenous Australia, supported by BP. This exhibition will be the first in the UK devoted to the history and culture of Indigenous Australians: both Aboriginal peoples and Torres Strait Islanders. Drawing on objects from the British Museum’s collection, accompanied by important loans from British and Australian collections, the show will present Indigenous Australia as a living culture, with a continuous history dating back over 60,000 years.

    The objects in the exhibition will range from a shield believed to have been collected at Botany Bay in 1770 by Captain Cook or one of his men, a protest placard from the Aboriginal Tent Embassy established in 1972, contemporary paintings and specially commissioned artworks from leading Indigenous artists. Many of the objects in the exhibition have never been on public display before.

    The objects displayed in this exhibition are immensely important. The British Museum’s collection contains some of the earliest objects collected from Aboriginal people and Torres Strait Islanders through early naval voyages, colonists, and missionaries dating as far back as 1770. Many were collected at a time before museums were established in Australia and they represent tangible evidence of some of the earliest moments of contact between Aboriginal people, Torres Strait Islanders and the British. Many of these encounters occurred in or near places that are now major Australian cities such as Sydney, Melbourne, Adelaide, and Perth. As a result of collecting made in the early 1800s, many objects originate from coastal locations rather than the arid inland areas that are often associated with Indigenous Australia in the popular imagination.

    The exhibition will not only present Indigenous ways of understanding the land and sea but also the significant challenges faced by Indigenous Australians from the colonial period until to the present day. In 1770 Captain Cook landed on the east coast of Australia, a continent larger than Europe. In this land there were hundreds of different Aboriginal groups, each inhabiting a particular area, and each having its own languages, laws and traditions. This land became a part of the British Empire and remained so until the various colonies joined together in 1901 to become the nation of Australia we know today. In this respect, the social history of 19th century Australia and the place of Indigenous people within this is very much a British story. This history continues into the twenty first century. With changing policies towards Indigenous Australians and their struggle for recognition of civil rights, this exhibition shows why issues about Indigenous Australians are still often so highly debated in Australia today.


    The exhibition brings together loans of special works from institutions in the United Kingdom, including the British Library, the Pitt Rivers Museum and the Cambridge Museum of Archaeology and Anthropology. A number of works from the collection of the National Museum of Australia will be shown, including the masterpiece ‘Yumari’ by Uta Uta Tjangala. Tjangala was one of the artists who initiated the translation of traditions of sand sculptures and body painting onto canvas in 1971 at Papunya, a government settlement 240km northwest of Alice Springs in the Northern Territory. Tjangala was also an inspirational leader who developed a plan for the Pintupi community to return to their homelands after decades of living at Papunya. A design from ‘Yumari’ forms a watermark on current Australian passports.

    This exhibition has been developed in consultation with many Aboriginal and Torres Strait Islander individuals, Indigenous art and cultural centres across Australia, and has been organised with the National Museum of Australia. The broader project is a collaboration with the National Museum of Australia. It draws on a joint research project, funded by the Australian Research Council, undertaken by the British Museum, the National Museum of Australia and the Australian National University. Titled ‘Engaging Objects: Indigenous communities, museum collections and the representation of Indigenous histories’, the research project began in 2011 and involved staff from the National Museum of Australia and the British Museum visiting communities to discuss objects from the British Museum’s collections. The research undertaken revealed information about the circumstances of collecting and significance of the objects, many of which previously lacked good documentation. The project also brought contemporary Indigenous artists to London to view and respond to the Australian collections at the British Museum.

    Neil MacGregor, Director of the British Museum said, “The history of Australia and its people is an incredible, continuous story that spans over 60,000 years. This story is also an important part of more recent British history and so it is of great significance that audiences in London will see these unique and powerful objects exploring this narrative. Temporary exhibitions of this nature are only possible thanks to external support so I am hugely grateful to BP for their longstanding and on-going commitment to the British Museum. I would also like to express my gratitude to our logistics partner IAG Cargo and the Australian High Commission who are supporting the exhibition’s public programme.”

  • Fossils: Ancient DNA traces extinct Caribbean 'Island Murderer' back to the dawn of mammals

    Fossils: Ancient DNA traces extinct Caribbean 'Island Murderer' back to the dawn of mammals

    From skeletal remains found among ancient owl pellets, a team of scientists has recovered the first ancient DNA of the extinct West Indian mammal Nesophontes, meaning "island murder." They traced its evolutionary history back to the dawn of mammals 70 million years ago.

    The authors, including Selina Brace, Jessica Thomas, Ian Barnes et al., published their findings in the advanced online edition of >Molecular Biology and Evolution.

    The insect-eating creature existed in the Caribbean islands until the 16th century when, perhaps, they were outcompeted as the first Spanish ships arrived—-introducing rats as stowaways. "Nesophontes was just one of the dozens of mammals that went extinct in the Caribbean during recent times," said Professor Ian Barnes, Research Leader at London's Natural History Museum.

    Scientists used a 750-year-old specimen to generate many thousands of base pairs of DNA sequence data. This allowed the research team to uncover its evolutionary origins and finally resolve the relationships between its closest relatives, the insectivores, a group including shrews, hedgehogs and moles. Phylogenetic and divergence time scenarios clearly demonstrate that Nesophontes is a deeply distinct sister group to another group of living native Caribbean insectivores, the solenodons. The time of the split between these two correlates with an era when the northern Caribbean was formed of volcanic islands, well before the origins of the islands we see today.

    Obtaining DNA from tropical fossils is notoriously difficult, and the team made use of the latest developments in ancient DNA technology to conduct the study.

    "Once we'd dealt with the tiny size of the bone samples, the highly degraded state of the DNA, and the lack of any similar genomes to compare to, the analysis was a piece of cake," said Natural History Museum scientist Dr. Selina Brace.

    The findings will be of considerable interest for evolutionary biologists studying mammalian biogeography, and the significant role that humans may have played in a recent extinction.

    Analysis of ancient cadavers recovered at a famous archaeological site confirm the existence of a sophisticated culture of butchering and carving human remains, according to a team of scientists from the Natural History Museum, University College London, and a number of Spanish universities.

    Gough's Cave in Somerset was thought to have given up all its secrets when excavations ended in 1992, yet research on human bones from the site has continued in the decades since.

    After its discovery in the 1880s, the site was developed as a show cave and largely emptied of sediment, at times with minimal archaeological supervision.

    The excavations uncovered intensively-processed human bones intermingled with abundant butchered large mammal remains and a diverse range of flint, bone, antler, and ivory artefacts.

    New radiocarbon techniques have revealed remains were deposited over a very short period of time, possibly during a series of seasonal occupations, about 14,700 years ago.

    Dr Silvia Bello, from the Natural History Museum's Department of Earth Sciences, lead researcher of the work said, "The human remains have been the subject of several studies. In a previous analysis, we could determine that the cranial remains had been carefully modified to make skull-cups. During this research, however, we've identified a far greater degree of human modification than recorded in earlier. We've found undoubting evidence for defleshing, disarticulation, human chewing, crushing of spongy bone, and the cracking of bones to extract marrow."

    The presence of human tooth marks on many of the bones provides incontrovertible evidence for cannibalism, the team found. In a wider context, the treatment of the human corpses and the manufacture and use of skull-cups at Gough's Cave has parallels with other ancient sites in central and western Europe.

    But the new evidence from Gough's Cave suggests that cannibalism during the 'Magdalenian period' was part of a customary mortuary practice that combined intensive processing and consumption of the bodies with the ritual use of skull-cups.

    Simon Parfitt, of University College London, said, "A recurring theme of this period is the remarkable rarity of burials and how commonly we find human remains mixed with occupation waste at many sites. Further analysis along the lines used to study Gough's Cave will help to establish whether the type of ritualistic cannibalism practiced there is a regional ('Creswellian') phenomenon, or a more widespread practice found throughout the Magdalenian world."

  • Great Legacy: Fossils and minerals take the antiques market by storm

    Great Legacy: Fossils and minerals take the antiques market by storm

    Throughout the Renaissance, the demand for antiques among the aristocracy burgeoned, with the trend soaring by the late 17th century as members of the upper classes began scouring Europe in search of bronzes, sculptures, prints, lamps and vases. With disposable income then rising among the aspiring middle classes in the latter part of the 19th century, the bourgeoisie took to investing in their homes and in the finer things as well. As antiques went mainstream, the market boomed in the hubs of London and Paris.

    is having its own revival [Credit: European CEO]

    However, despite this generally rising appetite, antiques have a tendency to go in and out of fashion, as evidenced by the lulls in between the booms of the 1950s and 1980s. At present, the market is experiencing yet another lull; new tastes and values have sent demand and prices for antiques crashing, leaving armoires, bejewelled knick-knacks and Regency dining chairs unwanted and unsold, and causing many industry players to close down or change course entirely. Yet, in the midst of all the doom and gloom for antiques aficionados, there is some cause for optimism in a few niche areas, especially when it comes to fossils and minerals.

    Out with the old

    With so many more people living in smaller abodes these days – urban dwellers in particular – there is very little space for antique desks and looming tapestries. Nor, in fact, do such items match contemporary tastes, as interior design trends have changed considerably over the past decade or two. Sleek and modern pieces, airy spaces and overall functionality are the style du jour; cluttered rooms and bulky furniture seem to have little place in 21st century life.

    “In general, young people have lost interest, and it is mostly older people who are buying – and obviously this area of the population is one that declines”, said Errol Fuller, a curator at Summers Place Auctions, and a leading expert on fossils and extinct species. “Not all areas of antique collecting are in retreat; it is the more drab brown furniture and traditional items that young people have little interest in. They look old-hat and boring.”

    Given the niche knowledge and training required to even begin delving into the subject, Baby Boomers and Millennials are largely uninterested in antiques. Adding further to this growing indifference is the reputation antiques have for popularity among the older generations – a status consolidated by television programmes, such as the US and UK versions of Antiques Roadshow, that depict the field as a hobby for pensioners. The downsizing of former antiques hubs, such as London’s Fulham Road and New York’s Kentshire Gardens, reflects this shift further still, indicating the market in general has indeed reached a precarious state.

    In with the even older

    Over the past year or so, one big trend that is offering hope to those in the trade is the growing popularity of fossils and minerals.

    “Decorative items, or things with intrinsic interest, still have appeal, and fossils and minerals have much of this quality. As do antique stuffed animals and birds. And it is these kind of things that are appealing to the young”, Fuller said. “The general public is becoming increasingly interested in the natural world – perhaps because we realise that much of it is vanishing at an alarming rate. We are becoming more conscious of anything to do with nature and to call a piece of natural history your own and to look after it for a few more years and save it for generations to come, is quite special.”

    This interest in the natural can be seen across numerous sectors and industries: food, make-up and alternative therapies, to name but a few. It would seem, as these trends indicate, that people are done with the artificial and are tired of fakery; they yearn for something with authenticity. Items such as fossils and minerals offer a window into the natural world within one’s own home.

    “Some are incredibly rare as well. But I think the main point is that most people are in sheer awe when they look at something that was created millions of years ago and which is still appealing to us”, said Fuller. “To imagine that this fossilised dinosaur or crab used to live on this planet such a long time ago, and is now one of the prized possessions in your collection is quite mind-blowing. Antiques and the amazing craftsmanship used to create them will always attract us, but I think it is the fact that fossils are not man-made that makes us look at them in wonder.”

    Crucial to this trend is the fact that fossils and minerals complement almost any type of interior design. They offer contrast to a modern room with soft furnishings, yet not in the garish way that a cumbersome 17th century dining table might. Given the variety of sizes, colours and types available, there is something for everyone and every budget. “Fossils are also still reasonably priced, so are more accessible to the general public and not restricted to those with millions in their bank accounts”, Fuller said.

    Their backgrounds make talking points like no other; it’s impossible not to be interested in their age, formation and aesthetic value.

    “They are not man-made and, in terms of antiquity, they are much older. And, of course, they almost always have a story”, Fuller said. “People tend to buy antiques because they are interested in their history and they look great in their homes. Fossils and minerals tick all those boxes, but as our homes are getting more contemporary, fossils actually fit in better. They look better in a minimalist home than most antiques, while still being quirky enough to be a real focal point.”

    When asked if he sees this trend continuing in the coming years, Fuller’s response was clear: “Absolutely, and especially because it is an area in which young people are becoming particularly interested, for all the above reasons. Summers Place Auctions established specific natural history sales with our first Evolution sale in 2013, but we have since gone from one specialist auction a year to including natural history items in all our sales – four in total. There is always a huge interest, but our last sale, which included the natural history collection of the Emmen Zoo, was the best yet – every single lot sold. We offered items at prices as low as £30, up to over £100,000.”

    Cyclical nature

    As shown throughout history, the trend for antiques in the home comes in waves. Wider phenomena, it would seem, have a large role to play; something may occur in popular culture that can ignite a craze, and a shift within an economy can spur a new trend. Take the hit show Mad Men; watched by millions and considered by many to be one of the greatest dramas of all time, the programme, which depicted life in a New York advertising agency in the 1960s, had a direct impact on the antique market. As the show’s popularity grew, so did that of sleek mid-century furniture, with sales of pieces by Charles and Ray Eames, and Jean-Michel Frank soaring during the show’s run. However, sales of such items have begun to slow once more since the show ended in 2015, demonstrating the fickle nature of tastes and trends when it comes to interior design, popular culture and what’s ‘in’.

    The growing demand for Chinese antiquities offers another important lesson for the antiques world. Given the exponential growth in the Chinese economy over the past three decades, a huge social shift has taken place in the country, with a sizeable middle class now present for the first time in the country’s history. This expansion and growth in disposable income has allowed considerably more people in China to own their own homes and, consequently, to invest in them and in objects of aesthetic value. Interestingly, this shift has taken place at the same time as a significant cultural transition within the country, whereby symbols of the past, which were once neglected and even rejected, have regained their prominence. Until recently, all reminders of the China’s imperial past were overlooked by the ruling regime and, as a result, the public. However, a renewed zeal for Chinese history has seen citizens reach out for objects of cultural significance. This trend has led Chinese buyers to scour the globe in search of rare pieces.

    The western trend for fossils and minerals may be in line with contemporary tastes, yet this too is likely to pass at some point – it may take several years, but it will pass. Evidently, the appetite for antiques, and for the various individual categories themselves, comes and goes. They are a reflection of society, the state of the economy, and of what was valued at any one time. At present, we are at a stage where the natural is lovingly embraced, which is clearly reflected in what we eat and how we style our homes. But the future may look very different. Perhaps period decor will come back into fashion, perhaps the dining room will have a revival, and maybe even large brown furniture will have its day once more.

    Ultimately, the antiques market has a life of its own. It has its own ebb and flow, and is certainly an interesting reflection of society. Although the antique market is shrinking in general, all is not lost for those invested in it; who knows what we’ll once again value in the future?

  • Genetics: A 100-million-year partnership on the brink of extinction

    Genetics: A 100-million-year partnership on the brink of extinction

    A relationship that has lasted for 100 million years is at serious risk of ending, due to the effects of environmental and climate change. A species of spiny crayfish native to Australia and the tiny flatworms that depend on them are both at risk of extinction, according to researchers from the UK and Australia.

    Look closely into one of the cool, freshwater streams of eastern Australia and you might find a colourful mountain spiny crayfish, from the genus Euastacus. Look even closer and you could see small tentacled flatworms, called temnocephalans, each only a few millimetres long. Temnocephalans live as specialised symbionts on the surface of the crayfish, where they catch tiny food items, or inside the crayfish's gill chamber where they can remove parasites. This is an ancient partnership, but the temnocephalans are now at risk of coextinction with their endangered hosts. Coextinction is the loss of one species, when another that it depends upon goes extinct.

    In a new study, researchers from the UK and Australia reconstructed the evolutionary and ecological history of the mountain spiny crayfish and their temnocephalan symbionts to assess their coextinction risk. This study was based on DNA sequences from crayfish and temnocephalans across eastern Australia, sampled by researchers at James Cook University, sequenced at the Natural History Museum, London and Queensland Museum, and analysed at the University of Sydney and the University of Cambridge. The results are published in the >Proceedings of the Royal Society B.

    "We've now got a picture of how these two species have evolved together through time," said Dr Jennifer Hoyal Cuthill from Cambridge's Department of Earth Sciences, the paper's lead author. "The extinction risk to the crayfish has been measured, but this is the first time we've quantified the risk to the temnocephalans as well -- and it looks like this ancient partnership could end with the extinction of both species."

    Mountain spiny crayfish species diversified across eastern Australia over at least 80 million years, with 37 living species included in this study. Reconstructing the ages of the temnocephalans using a 'molecular clock' analysis showed that the tiny worms are as ancient as their crayfish hosts and have evolved alongside them since the Cretaceous Period.

    Today, many species of mountain spiny crayfish have small geographic ranges. This is especially true in Queensland, where mountain spiny crayfish are restricted to cool, high-altitude streams in small pockets of rainforest. This habitat was reduced and fragmented by long-term climate warming and drying, as the continent of Australia drifted northwards over the last 165 million years. As a consequence, mountain spiny crayfish are severely threatened by ongoing climate change and the International Union for the Conservation of Nature (IUCN) has assessed 75% of these species as endangered or critically endangered.

    "In Australia, freshwater crayfish are large, diverse and active 'managers', recycling all sorts of organic material and working the sediments," said Professor David Blair of James Cook University in Australia, the paper's senior author. "The temnocephalan worms associated only with these crayfish are also diverse, reflecting a long, shared history and offering a unique window on ancient symbioses. We now risk extinction of many of these partnerships, which will lead to degradation of their previous habitats and leave science the poorer."

    The crayfish tend to have the smallest ranges in the north of Australia, where the climate is the hottest and all of the northern species are endangered or critically endangered. By studying the phylogenies (evolutionary trees) of the species, the researchers found that northern crayfish also tended to be the most evolutionarily distinctive. This also applies to the temnocephalans of genus Temnosewellia, which are symbionts of spiny mountain crayfish across their geographic range. "This means that the most evolutionarily distinctive lineages are also those most at risk of extinction," said Hoyal Cuthill.

    The researchers then used computer simulations to predict the extent of coextinction. This showed that if all the mountain spiny crayfish that are currently endangered were to go extinct, 60% of their temnocephalan symbionts would also be lost to coextinction. The temnocephalan lineages that were predicted to be at the greatest risk of coextinction also tended to be the most evolutionarily distinctive. These lineages represent a long history of symbiosis and coevolution of up to 100 million years. However they are the most likely to suffer coextinction if these species and their habitats are not protected from ongoing environmental and climate change.

    "The intimate relationship between hosts and their symbionts and parasites is often unique and long lived, not just during the lifespan of the individual organisms themselves but during the evolutionary history of the species involved in the association," said study co-author Dr Tim Littlewood of the Natural History Museum. "This study exemplifies how understanding and untangling such an intimate relationship across space and time can yield deep insights into past climates and environments, as well as highlighting current threats to biodiversity."

  • Fossils: Long-necked dino species discovered in Australia

    Fossils: Long-necked dino species discovered in Australia

    The Australian Age of Dinosaurs Museum today announced the naming of Savannasaurus elliottorum, a new genus and species of dinosaur from western Queensland, Australia. The bones come from the Winton Formation, a geological deposit approximately 95 million years old.

    Savannasaurus was discovered by David Elliott, co-founder of the Australian Age of Dinosaurs Museum, while mustering sheep in early 2005. As Elliott recalled yesterday, "I was nearly home with the mob -- only about a kilometre from the yards -- when I spotted a small pile of fossil bone fragments on the ground. I was particularly excited at the time as there were two pieces of a relatively small limb bone and I was hoping it might be a meat-eating theropod dinosaur." Mr Elliott returned to the site later that day to collect the bone fragments with his wife Judy, who 'clicked' two pieces together to reveal a complete toe bone from a plant-eating sauropod. The Elliotts marked the site and made arrangements to hold a dig later that year.

    The site was excavated in September 2005 by a joint Australian Age of Dinosaurs (AAOD) Museum and Queensland Museum team and 17 pallets of bones encased in rock were recovered. After almost ten years of painstaking work by staff and volunteers at the AAOD Museum, the hard siltstone concretion around the bones was finally removed to reveal one of the most complete sauropod dinosaur skeletons ever found in Australia. More excitingly, it belonged to a completely new type of dinosaur.

    The new discovery was nicknamed Wade in honour of prominent Australian palaeontologist Dr Mary Wade. "Mary was a very close friend of ours and she passed away while we were digging at the site," said Mr Elliott. "We couldn't think of a better way to honour her than to name the new dinosaur after her."

    "Before today we have only been able to refer to this dinosaur by its nickname," said Dr Stephen Poropat, Research Associate at the AAOD Museum and lead author of the study. "Now that our study is published we can refer to Wade by its formal name, Savannasaurus elliottorum," Dr Poropat said. "The name references the savannah country of western Queensland in which it was found, and honours the Elliott family for their ongoing commitment to Australian palaeontology."

    In the same publication, Dr Poropat and colleagues announced the first sauropod skull ever found in Australia. This skull, and the partial skeleton with which it was associated, has been assigned to Diamantinasaurus matildae -- a sauropod dinosaur named in 2009 on the basis of its nickname Matilda. "This new Diamantinasaurus specimen has helped to fill several gaps in our knowledge of this dinosaur's skeletal anatomy," said Poropat. "The braincase in particular has allowed us to refine Diamantinasaurus' position on the sauropod family tree."

    Dr Poropat collaborated with British sauropod experts Dr Philip Mannion (Imperial College, London) and Professor Paul Upchurch (University College, London), among others, to work out the position of Savannasaurus (and refine that of Diamantinasaurus) on the sauropod family tree. "Both Savannasaurus and Diamantinasaurus belong to a group of sauropods called titanosaurs. This group of sauropods includes the largest land-living animals of all time," said Dr Mannion. "Savannasaurus and the new Diamantinasaurus specimen have helped us to demonstrate that titanosaurs were living worldwide by 100 million years ago."

    Poropat and his colleagues suggest that the arrangement of the continents, and the global climate during the middle part of the Cretaceous Period, enabled titanosaurs to spread worldwide.

    "Australia and South America were connected to Antarctica throughout much of the Cretaceous," said Professor Upchurch. "Ninety-five million years ago, at the time that Savannasaurus was alive, global average temperatures were warmer than they are today. However, it was quite cool at the poles at certain times, which seems to have restricted the movement of sauropods at polar latitudes. We suspect that the ancestor of Savannasaurus was from South America, but that it could not and did not enter Australia until approximately 105 million years ago. At this time global average temperatures increased allowing sauropods to traverse landmasses at polar latitudes."

    Savannasaurus was a medium-sized titanosaur, approximately half the length of a basketball court, with a long neck and a relatively short tail. "With hips at least one metre wide and a huge barrel-like ribcage, Savannasaurus is the most rotund sauropod we have found so far -- even more so than the somewhat hippopotamus-like Diamantinasaurus," said Dr Poropat. "It lived alongside at least two other types of sauropod (Diamantinasaurus and Wintonotitan), as well as other dinosaurs including ornithopods, armoured ankylosaurs, and the carnivorous theropod Australovenator."

    Mr Elliott is relieved that Wade can now join "Matilda" and the other new dinosaur species on display in the Museum's Holotype Room. "That this dinosaur specimen can now be displayed for our visitors is a testament to the efforts of numerous volunteers who have worked at the Museum on the fossils over the past decade," he said. Mr Elliott and Dr Poropat agree that the naming of Savannasaurus, the fourth new species published by the AAOD Museum, is just the tip of the iceberg with respect to the potential for new dinosaur species in western Queensland.

    "The Australian Age of Dinosaurs Museum has a massive collection of dinosaur fossils awaiting preparation and the number of specimens collected is easily outpacing the number being prepared by volunteers and staff in our Laboratory," Mr Elliott said. "The Museum already has the world's largest collection of bones from Australia's biggest dinosaurs and there is enough new material to keep us working for several decades."

    The paper naming the new dinosaur was published in >Scientific Reports.

  • Northern Europe: The last Viking and his 'magical' sword?

    Northern Europe: The last Viking and his 'magical' sword?

    Have you held the sword? Have you felt its weight? Have you felt how sharp and strong the blade is?

    A deadly weapon and symbol of power -- jewellery for a man, with magical properties. The sword gave power to the warrior, but the warrior's strength could also be transferred to the sword. That is how they were bound together: man and weapon, warrior and sword.

    This sword was found in Langeid in Bygland in Setesdal in 2011. It is a truly unique sword from the late Viking Age, embellished with gold, inscriptions and other ornamentation. The discovery of the sword has not been published until now, when it is being displayed for the first time in the exhibition 'Take It Personally' at the Historical Museum in Oslo.

    The sword must have belonged to a wealthy man in the late Viking Age. But who was he and what magic inscriptions are set into the decoration -- in gold? Was the owner of the sword in the Danish King Canute's army when it attacked England in 1014-15?

    "We just gaped"

    In the summer of 2011, archaeologists from the Museum of Cultural History in Oslo discovered a Viking burial ground in Langeid in Setesdal in southern Norway. In one of the graves they made a startling discovery.

    "Even before we began the excavation of this grave, I realised it was something quite special. The grave was so big and looked different from the other 20 graves in the burial ground. In each of the four corners of the grave there were post holes," said excavation leader Camilla Cecilie Wenn of the Museum of Cultural History.

    The post holes reveal that there was a roof over the grave, which is a sign that the grave had a prominent place in the burial ground. But when they dug down in the coffin in the bottom of the grave, there were few traces of gifts for the afterlife, only two small fragments of silver coins. The coins were from northern Europe; one was probably from the German Viking Age, judging by how it was embossed, while the other was a penny minted under Ethelred II in England dating from the period 978-1016.

    "But when we went on digging outside the coffin, our eyes really popped. Along both sides, something metal appeared, but it was hard to see what it was. Suddenly a lump of earth fell to one side so that the object became clearer. Our pulses raced when we realised it was the hilt of a sword! And on the other side of the coffin, the metal turned out to be a big battle-axe. Although the weapons were covered in rust when we found them, we realised straight away that they were special and unusual. Were they put there to protect the dead person from enemies, or to display power?"

    Dating of charcoal from one of the post holes shows that the grave is from around the year 1030, at the very end of the Viking Age. "And that fits in well with the discovery of the English coin."

    The sword

    The sword must have belonged to a wealthy man who lived in the late Viking Age. The sword is 94 cm long; although the iron blade has rusted, the handle is well preserved. It is wrapped with silver thread and the hilt and pommel at the top are covered in silver with details in gold, edged with a copper alloy thread," said project leader Zanette Glørstad.

    The last Viking and his 'magical' sword?

    of Cultural History, University of Oslo]

    "When we examined the sword more closely, we also found remnants of wood and leather on the blade. They must be remains from a sheath to put the sword in," explained curator Vegard Vike. He has had the challenging task of cleaning up the handle and preserving the sword.

    The sword is decorated with large spirals, various combinations of letters and cross-like ornaments. The letters are probably Latin, but what the letter combinations meant is still a mystery.

    "At the top of the pommel, we can also clearly see a picture of a hand holding a cross. That's unique and we don't know of any similar findings on other swords from the Viking Age. Both the hand and the letters indicate that the sword was deliberately decorated with Christian symbolism. But how did such a sword end up in a pagan burial ground in Norway? The design of the sword, the symbols and the precious metal used all make it perfectly clear that this was a magnificent treasure, probably produced abroad and brought back to Norway by a very prominent man," added Camilla Cecilie Weenn.

    "The way swords are referred to in the sagas suggests that the sword is an important bearer of the identity of the warrior. A sword reveals the warrior's social status, his position of power and his strength. The sagas also tell us that gold had a special symbolic value in Norse society. In Norse literature gold represented power and potency.

    Gold is rarely found in archaeological material from Viking Period and then too, it stood for power and potency. This indicates that gold had considerable economic and symbolic value. Based on the descriptions in the literature, we can say that the sword was the male jewellery par excellence of the Viking Age," said Hanne Lovise Aannestad, the author of a recent article on ornate swords from the days of the Vikings.

    'Magic'

    The sagas emphasise the importance of the ornate sword. Swords could have hilts of gold with ornamentation and magical runes. The mythical sagas tell of magical swords forged by dwarfs. The creation of myths around the art of the blacksmith and the making of high-quality swords may be related to the fact that few people mastered the art. The production of metal objects of high quality may have been a form of hidden knowledge unavailable to most people. This gave the objects a magical aura.

    "In Mediaeval literature, swords are referred to as aesthetic, powerful and magical objects. The many similarities between the descriptions of swords in Norse and Mediaeval literature suggest that the splendour of the sword in the latter had roots in the Viking notions of the symbolic power, magic and ritual aspects of the ornate sword. The Viking Age was a period of great social upheaval. At times like that, certain symbolic objects may play an important role in negotiating social positions. There is much to suggest that these magnificent swords were such objects, reflecting the status and power of the warrior and his clan," said Hanne Lovise.

    The battle-axe

    The axe found in the same grave has no gold decoration. But the shaft is coated with brass and it may well have flashed like gold when the sun shone. Such shaft coatings are very rare in Norway. But a number of similar battle-axes have been found in the River Thames in London. That makes the axe particularly interesting. Dating of the axe from Langeid shows that it belongs to the same period as the axes found in the Thames. There was a long series of battles along the Thames in the late 10th and early 11th centuries. The Danish king Sweyn Forkbeard and his son Canute led their armies against the English king in the battle for the English throne. Even the Norwegian king Olav (Haraldsson) the Holy was involved in the attack on London in 1009. The men under the Danish King were from all over Scandinavia. Did the axes get lost in the Thames during the numerous skirmishes, or did the victors throw them in the river?

    Did the sword belong to a Viking from King Canute's army?

    Further down the Setesdal Valley we find a runic stone, which says: "Arnstein raised this stone in memory of Bjor his son. He found death when Canute "went after" England. God is one." (Translated from the Old Norse). The text probably refers to King Canute's attacks on England in 1013-14. It is likely that the stone was erected just after the incursions, by a father whose son never came back home. A written source from the 12th century states that King Canute's closest army had to meet certain requirements. Soldiers had to honour the king, had to belong to the leading families in society and also had to provide their own gilded axes and sword hilts.

    The Langeid sword would no doubt have been approved by King Canute, probably also the axe. The sword was made outside Norway and an Anglo-Saxon origin is quite possible. The axe is very similar to those found in the Thames, especially in its brass coating. The grave with the sword also contained the only coin found in Langeid from the Anglo-Saxon region, which increases the possibility that the dead man had a particular connection to the events in England.

    "It's quite possible that the dead man was one of King Canute's hand-picked men for the battles with King Ethelred of England. Seen in connection with the runic stone further down the valley, it is tempting to suggest that it is Bjor himself who was brought home and buried here. Another possibility is that his father Arnstein only got his son's magnificent weapons back and that, precisely for that reason, he decided to erect a runic stone for his son as a substitute for a grave. When Arnstein himself died, his son's glorious weapons were laid in his grave. The death of his son must have been very tough on an old man. Perhaps their relatives honoured both Arnstein and Bjor by letting Arnstein be buried with the weapons with such a heroic history," said Zanette Glørstad.

    The runic stone dates from the same period as the final phase of the burial ground and testifies that Christianity is about to take root in Norwegian society. It is the oldest runic stone in Norway that refers to Christianity. Could this also explain why the weapons were placed outside the coffin? In a transitional period, people may have chosen to use both pagan and Christian elements in a funeral. The Langeid grave is from one of the last pagan funerals we know of from Norway and marks both the greatness and the end of the Viking Age.

    "Take it personally"

    Ever since the summer of 2011, the sword found in Langeid has been unpublished. Its display today has been made possible by the meticulous work and research of conservators and archaeologists at the Museum of Cultural History. Finally, it can be seen by the public and is displayed in the exhibition called "Take it personally" -- an exhibition of personal jewellery and adornment over time and space in the Historical Museum in Oslo.

    UK: DNA of bacteria responsible for London Great Plague of 1665 identified

    Scientific analysis of skeletons excavated as part of the Crossrail Programme has identified the DNA of the bacteria responsible for the 1665 Great Plague.

    The discovery comes following a year-long study of skeletons found in a mass grave within the New Churchyard, the burial ground excavated by Museum of London Archaeology (MOLA) during construction of the new Elizabeth line station at Liverpool Street in 2015.

    The mass grave has been dated between 1650 and 1670 using fragments of pottery, glass and coffin handles found within the pit. Local burial records confirm there was a dramatic rise in burial rates in the New Churchyard when the epidemic peaked in the summer of 1665. Historic accounts, such as Daniel Defoe’s ‘A Journal of the Plague Year’ and the Court of Aldermen records, paint a vivid picture of the graveyard’s struggle to cope with a crisis of capacity at that time.

    Samples from 20 individuals were tested for traces of the plague pathogen Yersinia pestis, and five were found to have been exposed to it before they died. Due to the disease’s virulence it is likely that this exposure was the cause of death. This is the first identification of plague DNA from 17th Century Britain. The bacteria itself perished days after the individuals died 351 years ago and is no longer active.

    The Great Plague of 1665 was the last major bubonic plague epidemic in Britain and killed an estimated 100,000 people in London, almost a quarter of the population. Despite its scale, the pathogen responsible has eluded detection as the fast-acting disease left no traces on skeletons and the DNA has a low-survival rate when buried in the ground for hundreds of years.

    Modern scientific techniques have allowed scientists at the Max Planck Institute in Jena, Germany, to isolate this DNA from teeth extracted from the skeletons. The enamel on the teeth acted as protective capsules, preserving the DNA of bacteria that was in the person’s bloodstream at the time of death.

    Molecular palaeopathologists are now attempting to sequence the pathogen’s full DNA genome. In doing so they hope to be able to compare the 1665 Great Plague to the 1348 Black Death epidemic as well as recent modern outbreaks. This will allow scientists to further understand the evolution and spread of the disease.

    Jay Carver, Crossrail Lead Archaeologist, said: “The Crossrail project has given archaeologists a rare opportunity to study previously inaccessible areas of London. The discovery of the ancient DNA, which has eluded scientists for so long, is yet another piece of the jigsaw that we are piecing together to learn more about the lives and deaths of 16th to 18th Century Londoners.”

    Don Walker, Senior Osteologist at MOLA, said: “This is a hugely significant discovery as it is the first identification of ancient DNA from the 1665 Great Plague in Britain. This discovery has the potential to greatly enhance scientist’s understanding of the disease and coupled with detailed research of the skeletons reveal more about this devastating epidemic and the lives of its victims.”

    Vanessa Harding, Professor of London History, Birkbeck, University of London, said: “This is a very exciting finding, for the history of London, the history of disease, and the history of burial. It confirms thatYersinia pestis was present in early modern London plague epidemics, and links them epidemiologically with the 14th-Century Black Death and the 1720 Marseille plague. We still need, however, to understand why the disease manifested itself in so many different ways, and whether other pathogens made a significant contribution to these epidemics.

    “The excavation also underlines the strength of custom and order in time of crisis, showing that plague burial, even in mass graves, could be controlled and orderly, with bodies in coffins laid neatly on each other – not quite the shambolic ‘plague pit’ of popular discourse.”

    In total 42 individuals were excavated from the mass grave but archaeologists estimate that it may have contained as many as 100 people. The predominantly coffined burials were tightly packed in orderly rows that, over the centuries, collapsed in on each other as the coffins decayed. Although contemporary Plague Orders dictated that burials sit a minimum of 6ft from the surface, the top of the mass burial was only about 2ft from the surface. This was perhaps a matter of practicality for the gravediggers but ‘noisome stenches’ were reported, eventually leading to burial restrictions being placed on the New Churchyard.


    Further scientific analysis of the skeletons will continue over the coming months. Isotopic analysis may reveal where these people grew up and if they moved in their lifetimes, and examination of the material trapped within the plaque on the teeth may show what they ate, and what diseases and pollutants they were exposed to.

    In 2014, skeletons excavated during the construction of the Elizabeth line station at Farringdon were found to contain traces of the DNA of the Yersinia pestis bacteria from the first major plague epidemic in Europe, the 1348 Black Death.

    Crossrail’s extensive archaeology programme is the largest in the UK. To date it has found more than 10,000 artefacts and fossils spanning 55 million years of London’s past at over 40 construction sites. Full findings from the archaeological excavation at Liverpool Street will be published in early 2017.

    UK: Archaeologists search for Roman remains in Gloucester

    After uncovering a castle on a par with the Tower of London underneath the old prison in Gloucester, yet more artifacts have been dug up.

    Since the castle was found in December work has been on-going at both the Castle site and around Blackfriars.

    Archaeologists have dug a large trench off Quay Street as they explore for more finds both on the castle site and other sites in the city. At the castle further medieval structures have been found on the site.

    Andrew Armstrong, archaeologist at Gloucester City Council, said: "From an archaeological point of view this is a hugely interesting and important part of the city.

    "It includes the south-west corner of the Roman city of Glevum, the old Roman waterfront, the site of the Norman Castle (the 'Old Castle') which extends throughout the southern half of Bearland car park. It also holds the site of the medieval castle (the New Castle) which extends from the site of the old prison northwards into the Quayside area."

    So far medieval pottery has been found on the site as well as oyster shells, work has been on-going at the site Monday, April 4.

    Jon Eeles, amateur historian, said: "It is good news that this is being found and dug up but I don't want it flattened and built on. Tourists won't visit Gloucester to see a block of flats but they will visit to see historical remains."

    Mr Eeles would is an advocate for keeping the artefacts visible to the public but still protected.

    He added: "Bath got very badly bombed in the war, while Gloucester avoided much of it. Bath have managed to show off their history well despite the bombing, in Gloucester we have so much more history but have done a good job of hiding it."

    The archaeologists expect to find Roman town houses at the Quayside site.

    Chris Chatterton, manager of the Soldiers of Gloucester museum, said: "This site is the perfect microcosm of the history in Gloucester which is so broad. Nowhere else in the county has the history that Gloucester does."

    The work is taking place ahead of redevelopment plans of Gloucester around Quayside and Blackfriars. The area extends from Commercial Road in the south as far as Quay Street in the north.

    Mr Chatterton added: "It is a genuinely fascinating process and I am very interested to see what they find during the dig. If it is anything magnificent, like the recent dig at the prison site was, it needs to be preserved and protected for people to see."

  • North America: Site with clues to fate of fabled Lost Colony may be saved

    North America: Site with clues to fate of fabled Lost Colony may be saved

    Clues to what became of North Carolina's fabled Lost Colony could lie in a waterfront tract where developers once wanted to build thousands of condos - and now, one of those would-be developers is seeking millions of dollars to preserve the property.

    The effort to save the 1,000 acres in rural Bertie County is in an early stage. Even the environmental group that developer Michael Flannelly hopes will help hasn't seen the property yet. But Flannelly said he's optimistic that his vision will eventually become a reality.

    "I want to see the site preserved," said Flannelly, who lives on a boat that's usually docked in Norfolk, Virginia, or near his land in Bertie County. "I think it would make a fantastic place for people to come."

    The mystery of the Lost Colony - England's first settlement in North America - has intrigued historians and the popular imagination for centuries.

    In 1587, 116 English settlers landed on Roanoke Island, led by explorer John White. He left them there when he sailed back to England that same year for more supplies. Delayed by war between England and Spain, he didn't return until 1590 - and when he did, he discovered the entire colony had simply vanished.

    White knew the majority had planned to move "50 miles into the maine," as he wrote, referring to the mainland. The only clues he found about the fate of the other two dozen were the word "CROATOAN" carved into a post and "CRO" lettered on a tree trunk, leading historians to believe they moved south to live with American Indians on what's now Hatteras Island.

    But some archaeologists now suspect that at least some of the Roanoke colonists found their way to the inland site south of the Chowan River bridge, roughly 50 miles from Roanoke. It first came to light in 2012, when researchers at the British Museum in London announced they had found a drawing of a fort that had been obscured under a patch on a map of Virginia and North Carolina drawn by White in the 1580s.

    The drawing placed the fort in an area of Bertie County where archaeologists had found colonial-era English pottery and signs of a Native American village several years earlier during a dig that the state required before Flannelly and his partners could get permits for the subdivision that was never built. Archaeologists have since found further evidence on the tract, dubbed Site X, including bale seals used to verify cloth quality and 16th-century nails.

    Before the site can be preserved, Flannelly must buy out his former development partners.

    Flannelly estimates it will take $4 million to $5 million, along with a conservation group willing to help raise the money and preserve the land. To any cynics who suspect Flannelly is doing this only for the money, he says he would get 8 percent of any sale, plus a tax credit. And the proposed buyout is far less than the $10 million Flannelly says the developers paid for the property.

    A spokesman for the company, Forest City, said in an email that officials know about the archaeological finds but have no other updates about the status of the property. Forest City no longer works in land development, spokesman Jeff Linton said.

    Flannelly said that when archaeologists uncovered the property's historical significance, he insisted that those areas be cordoned off as green space and not developed.

    Flannelly personally owns 15 acres that include the possible Lost Colony site, but said he didn't know about the artifacts when he chose that land for his own home. "They felt the same I did," he said of the settlers. "That's the best piece of property on the whole tract."

    He has turned to North Carolina's Coastal Land Trust, a nonprofit that has preserved more than 65,000 undeveloped acres in 31 counties since 1992. Lee Leidy, attorney and northeast regional director for the trust, said officials there hope to view the property later this month.

    "It's fascinating," she said. "It's one that we're very excited to take a look at and learn more about."

    But raising funds to preserve the land presents a challenge, since limited conservation dollars must cover many projects, she said.

    "If it's done properly, I think it could be tremendous," said Arwin Smallwood, who wrote "Bertie County: An Eastern North Carolina History" and chairs the history department at N.C. A&T State University in Greensboro. "Right now in Bertie County, you can have a true sense of history and what the landscape was like."

    Tourists travel by the thousands to Dare County, home of the outdoor performance of "The Lost Colony" at an outdoor amphitheater on Roanoke Island. Now Bertie County residents have adopted the settlers as their own as well. More than 300 people attended the town of Windsor's first Lost Colony Festival in April, said Billy Smithwick, the town fire chief and tourism manager. In addition, the county is acquiring 137 acres for a nearby park.

    "I think it would be quite a tourist attraction," said Smithwick. "The Lost Colony is the greatest mystery in history that there is."

  • Greenland: Greenland on thin ice?

    Greenland: Greenland on thin ice?

    The ice sheet covering Greenland is four times bigger than California -- and holds enough water to raise global sea-level more than twenty feet if most of it were to melt. Today, sea levels are rising and the melting of Greenland is a major contributor. Understanding how fast this melting might proceed is a pressing question for policymakers and coastal communities.

    Greenland on thin ice?
    How much of Greenland's ice melted during past periods of global warming? Two first-of-their-kind studies in Nature look 
    much deeper into the history of Greenland than previous techniques allowed. One of the studies, led by University of 
    Vermont geologist Paul Bierman, concludes that East Greenland -- like the coastal scene shown in this image from near 
    Tasiilaq -- has been actively scoured by glacial ice for much of the last 7.5 million years. The other study presents 
    contrasting results suggesting the disappearance of the ice sheet over the center of Greenland during at least some 
    of the Pleistocene. The two studies improve our understand of Greenland's deep past, while raising questions 
    about both the past and future of its giant ice sheet in a changing climate [Credit: Joshua Brown/UVM]

    To make predictions about the future of the ice sheet, scientists have tried to understand its past, hoping to glean what the ice was doing millions of years ago when the Earth was three or more degrees Fahrenheit warmer than it is now. But our understanding of the ice sheet's complex behavior before about 125,000 years ago has been fragmentary at best.

    Now, two first-of-their-kind studies provide new insight into the deep history of the Greenland Ice Sheet, looking back millions of years farther than previous techniques allowed. However, the two studies present some strongly contrasting evidence about how Greenland's ice sheet may have responded to past climate change -- bringing new urgency to the need to understand if and how the giant ice sheet might dramatically accelerate its melt-off in the near future.

    The two new studies were published in the journal Nature, including one led by University of Vermont geologist Paul Bierman.

    Ice On the East

    In >the first study Bierman and four colleagues -- from UVM, Boston College, Lawrence Livermore Laboratory, and Imperial College London -- examined deep cores of ocean-bottom mud containing bits of bedrock that eroded off of the east side of Greenland. Their results show that East Greenland has been actively scoured by glacial ice for much of the last 7.5 million years -- and indicate that the ice sheet on this eastern flank of the island has not completely melted for long, if at all, in the past several million years. This result is consistent with existing computer models.

    Their field-based data also suggest that during major climate cool-downs in the past several million years, the ice sheet expanded into previously ice-free areas, "showing that the ice sheet in East Greenland responds to and tracks global climate change," Bierman says. "The melting we are seeing today may be out of the bounds of how the Greenland ice sheet has behaved for many millions of years."

    Since the data the team collected only came from samples off the east side of Greenland, their results don't provide a definitive picture of the whole Greenland ice sheet. But their research, with support from the National Science Foundation, provides strong evidence that "an ice sheet has been in East Greenland pretty much continuously for seven million years," says Jeremy Shakun, a geologist at Boston College who co-led the new study. "It's been bouncing around and dynamic -- but it's been there nearly all the time."

    Greenland on thin ice?
    Scientists drilled nearly two miles down through the summit of the Greenland ice sheet (white dot, left), to reach
     bedrock. Isotopes found in the rock indicate that this site and most of Greenland were nearly ice free (right)
     during the recent geologic past [Credit: Schaefer et al., Nature, 2016]

    Contrasting Results

    The >other study in Nature -- led by Joerg Schaefer of Lamont-Doherty Earth Observatory and Columbia University, and colleagues -- looked at a small sample of bedrock from one location beneath the middle of the existing ice sheet and came to what appears to be a different conclusion: Greenland was nearly ice-free for at least 280,000 years during the middle Pleistocene -- about 1.1 million years ago. This possibility is in contrast to existing computer models.

    "These results appear to be contradictory -- but they may not be," UVM's Bierman says. He notes that both studies have "some blurriness," he says, in what they are able to resolve about short-term changes and the size of the ancient ice sheet. "Their study is a bit like one needle in a haystack," he says, "and ours is like having the whole haystack, but not being sure how big it is."

    That's because Schaefer and colleagues' data comes from a single point in the middle of Greenland, pointing to a range of possible scenarios of what happened in the past, including several that challenge the image of Greenland being continuously covered by an extensive ice sheet during the Pleistocene. In contrast, Bierman and colleagues' data provides a record of continuous ice sheet activity over eastern Greenland but can't distinguish whether this was because there was a remnant in East Greenland or whether the ice sheet remained over the whole island, fluctuating in size as the climate warmed and cooled over millions of years.

    "It's quite possible that both of these records are right for different places," Bierman says. "Both of these studies apply a similar innovative technique and let us look much farther into the past than we have been able to before."

    New Method

    Both teams of scientists used, "a powerful new tool for Earth scientists," says Dylan Rood, a scientist at Imperial College London and a co-author on the Bierman-led study: isotopes within grains of quartz, produced when bedrock is bombarded by cosmic rays from space. The isotopes come into being when rock is at or near Earth's surface -- but not when it's buried under an overlying ice sheet. By looking at the ratio of two of these cosmic-ray-made elements -- aluminum-26 and beryllium-10 caught in crystals of quartz, and measured in an accelerator mass spectrometer -- the scientists were able to calculate how long the rocks in their samples had been exposed to the sky versus covered by ice.

    >Paul Bierman, a geologist at the University of Vermont and his colleagues --f rom UVM, Boston College, 
    >Lawrence Livermore Laboratory, and Imperial College London--wanted to develop a better understanding 
    >of the ancient history of the huge ice sheet that covers Greenland, like this portion of the ice sheet shown from 
    >a helicopter on a Bierman-led expedition there. The team studied deep cores of ocean-bottom mud containing 
    >bits of bedrock that eroded off of the east side of Greenland. Their results show that East Greenland has been 
    >actively scoured by glacial ice for much of the last 7.5 million years--and indicate that the ice sheet on the 
    >eastern flank of the island has not completely melted for long, if at all, in the past several million years. Their 
    >field-based data also suggest that during major climate cool-downs in the past several million years, the ice sheet 
    >expanded into previously ice-free areas, "showing that the ice sheet in East Greenland responds to and tracks
    > global climate change," Bierman says. "The melting we are seeing today may be out of the bounds of how 
    >the Greenland ice sheet has behaved for many millions of years." [Credit: Joshua Brown/UVM]
    This isotope technique has been used for several decades for measuring land-based erosion, but this is its first application to ocean core samples, said Lee Corbett, a postdoctoral researcher at UVM and co-author with Bierman. "This has never been attempted with marine sediments," she says. Their results overcome a basic problem of trying to discern the deep history of ice from bedrock: every time an ice sheet retreats and then grows back, it scours away the bedrock and the isotope record of its own past. "It's hard to discern an ice sheet's cycles on land because it destroys the evidence," she says, "but it dumps that evidence in the oceans, archived in layers on the bottom."

    Now Corbett, Shakun, and others are applying this isotope technique to additional cores taken from around the coast of Greenland to get a more complete and in-focus picture of the whole ice sheet's long history. And they have already applied the new isotope technique far beyond Greenland -- particularly in exploring the much larger, more mysterious ice sheets covering Antarctica.

    "These two apparently conflicting -- but not necessarily conflicting -- studies in Nature really force the issue that we don't know enough about how ice sheets work over deep time," Bierman says. "We must recognize the importance of advancing polar science to understand how our world works. And, right now, because we're pumping huge plumes of greenhouse gases into the atmosphere, we really need to know how our world works."

    The dynamics of Antarctica's giant ice sheet is full of questions and the disastrous potential. "But there's enough sea-level rise tied-up in Greenland alone to put a lot of cities and long stretches of coastline underwater," says Paul Bierman, "including Donald Trump's property in Florida."

    UK: Human presence in Ireland pushed back by 2,500 years

    A remarkable archaeological discovery in a Co. Clare cave has pushed back the date of human existence in Ireland by 2,500 years.

    This discovery re-writes Irish archaeology and adds an entirely new chapter to human colonisation of the island – moving Ireland’s story into a new era.

    Radiocarbon dating of a butchered brown bear bone, which has been stored in a cardboard box at the National Museum of Ireland for almost 100 years, has established that humans were on the island of Ireland some 12,500 years ago – 2,500 earlier than previously believed.

    Since the 1970s, the oldest evidence of human occupation on the island of Ireland has been at Mount Sandel in Co. Derry. This site has been dated at 8,000 BC, which is in the Mesolithic period, indicating that humans had occupied the island for some 10,000 years.

    However, new analysis of the bear patella – or knee bone – originally found in Co. Clare in 1903 gives us undisputed evidence that people existed in Ireland during the preceding Palaeolithic period at 10,500 BC, some 12,500 years ago.

    This is a major breakthrough for archaeologists who have spent decades searching for earlier signs of human occupation on the island.

    The discovery was made by Dr Marion Dowd, an archaeologist at IT Sligo, and Dr Ruth Carden, a Research Associate with the National Museum of Ireland.

    to have been made with a stone knife [Credit: James Connolly]

    “Archaeologists have been searching for the Irish Palaeolithic since the 19th century, and now, finally, the first piece of the jigsaw has been revealed. This find adds a new chapter to the human history of Ireland,” said Dr Dowd.

    Dowd and Carden’s paper on the discovery was published in the journal Quaternary Science Reviews. Dr Dowd is a lecturer in Prehistoric Archaeology at the School of Science in IT Sligo and is a specialist in Irish cave archaeology.

    The adult bear bone was one of thousands of bones originally discovered in Alice and Gwendoline Cave, Co. Clare in 1903 by a team of early scientists. They published a report on their investigations and noted that the bear bone had knife marks.

    The bone was stored in a collection at the National Museum of Ireland since the 1920s. In 2010 and 2011, animal osteologist Dr Ruth Carden, a Research Associate at the museum, was re-analysing its animal bone collections from early cave excavations. She came across the bear bone and documented it along with many others.

    As a specialist in cave archaeology, Dr Dowd, became interested in the butchered bear patella and, together with Dr Carden, the pair sought funding from the Royal Irish Academy for radiocarbon dating, which was carried out by the Chrono Centre at Queen’s University Belfast.

    “When a Palaeolithic date was returned, it came as quite a shock. Here we had evidence of someone butchering a brown bear carcass and cutting through the knee probably to extract the tendons. Yes, we expected a prehistoric date, but the Palaeolithic result took us completely by surprise,” says Dr Dowd.

    meaning it may have been killed and certainly butchered by some of the first 
    humans in Ireland after the last Ice Age [Credit: IT Sligo]

    A second sample was sent to the University of Oxford for radiocarbon dating to test the validity of the initial result. Both dates indicated human butchery of the bear about 12,500 years ago.

    The bone was then sent to three bone specialists for independent analysis of the cut marks. These were Dr Jill Cook at the British Museum in London; Prof. Terry O’Connor at the University of York and Prof. Alice Choyke at the Central European University in Hungary.

    The experts were unaware of the radiocarbon dating results prior to their examinations but all determined that the cut marks were made on fresh bone, confirming that the cut marks were of the same date as the patella, and therefore that humans were in Ireland during the Palaeolithic period.

    “This made sense as the location of the marks spoke of someone trying to cut through the tough knee joint, perhaps someone who was inexperienced,” explains Dr Dowd. “In their repeated attempts, they left seven marks on the bone surface. The implement used would probably have been something like a long flint blade.”

    “The bone was in fresh condition meaning that people were carrying out activities in the immediate vicinity – possibly butchering a bear inside the cave or at the cave entrance,” said Dr Dowd.

    Dr Ruth Carden said:  “From a zoological point of view, this is very exciting, since up to now we have not factored in a possible ‘human-dimension’ when we are studying patterns of colonisation and local extinctions of species to Ireland.

    “This paper should generate a lot of discussion within the zoological research world and it’s time to start thinking outside the box…or even dismantling it entirely!”


    Dr Dowd and Dr Carden are now hoping to get funding to carry out further analysis of other material recovered during the 1903 excavations, the cave itself and other potential cave sites around the country.

    Professor Vincent Cunnane, President of IT Sligo said: “Academic research is often lauded for helping to shape new concepts and innovations of the future, but this ground-breaking discovery for Irish archaeology highlights the vital role it can play in challenging and deepening our understanding of our heritage and history.”

    Nigel T. Monaghan, Keeper, Natural History Division of the National Museum of Ireland said: “The National Museum of Ireland – Natural History, holds collections of approximately two million specimens, all are available for research and we never know what may emerge. Radiocarbon dating is something never imagined by the people who excavated these bones in caves over a century ago, and these collections may have much more to reveal about Ireland’s ancient past.”

    The remarkable discovery comes just three years after the first evidence of Palaeolithic occupation of Scotland was uncovered. In 2013, a cache of flint tools was unearthed on the Isle of Islay, pushing the date of human existence in Scotland from the Mesolithic into the Palaeolithic era.

    The Museo Civico Archeologico is hosting Egypt. Millennia of Splendour. Beneath the two towers, the splendour of a civilisation that lasted thousands of years and has always fascinated the entire world, has sprung back to life: the Egypt of the pyramids, pharaohs and multiform gods, but also that of sensational discoveries, captivating archaeology, passionate collecting and rigorous scholarship.

    The exhibition ‘Egypt’, which is being held at the Museo Civico Archeologico in Bologna, is not just an exposition of high visual and scientific impact, but also an unprecedented international enterprise: the Egyptian collection of the National Museum of Antiquities in Leiden, Netherlands – among the top ten in the world – and that of the Bologna museum – among the most important in Italy for the quantity, quality and state of conservation of its collections – have been brought together in an exhibition space measuring around 1,700 metres, filled with art and history.

    500 finds, dating from the Pre-Dynastic Period to the Roman Period, gave been brought from the Netherlands to the Bologna museum. And, together with the masterpieces from Leiden and Bologna, the exhibition also includes important loans from the Museo Egizio in Turin and the Museo Egizio in Florence, creating a network of the most important Italian museums.

    For the first time, the masterpieces of the two collections are being displayed side by side, including the Stele of Aku (Twelfth–Thirteenth Dynasty, 1976–1648 BC), the ‘major domo of the divine offering’, with a prayer describing the otherworldly existence of the deceased in a tripartite world divided into sky, earth and the beyond; gold items attributed to General Djehuty, who led the Egyptian troops to victory in the Near East for the great conqueror Pharaoh Thutmose III (1479–1425 BC); the statues of Maya, superintendent of the royal treasury of Tutankhamen, and Merit, a chantress of the god Amun, (Eighteenth Dynasty, reigns of Tutankhamen and Horemheb, 1333–1292 BC), the most important masterpieces in the National Museum of Antiquities in Leiden have left the Netherlands for the first time for the Bologna exhibition; and, among the numerous objects attesting to the refined lifestyle of the most wealthy Egyptians, a Mirror Handle (1292 BC) in the shape of a young woman holding a small bird in her hand.

    Lastly, for the first time 200 years after the discovery of his tomb in Saqqara, the exhibition offers the unique and once-in-a-lifetime opportunity to see the important Reliefs of Horemheb reunited: Horemheb was the head commander of the Egyptian army during the reign of Tutankhamen, then rising to become the final sovereign of the Eighteenth Dynasty, from 1319 to 1292 BC and the reliefs are divided between the collections in Leiden, Bologna and Florence.

    Thousands of years of the history of a unique civilisation revealed in a major exhibition that brings together masterpieces from important world collections and tells of the pyramids and pharaohs, the great captains and priests, the gods and other divinities, and the people that made Egyptian history and that, thanks to discoveries, archaeology and collecting, never stop enchanting, revealing, intriguing, fascinating and charming generation after generation.

    The Seven Exhibition Sections

    The Pre-Dynastic and Archaic Periods – At the Origins of History: The transition from raw material to form, from the oral tradition to the written one and from prehistory to history was a fundamental moment for Egyptian civilisation. The Leiden collection is rich in materials documenting the central role played by nature during this long cultural and artistic evolution.

    The exhibition opens with a selection of these objects, which are strikingly modern in style, including a vase from the Naqada IID Period (named for a site in Upper Egypt and datable between 3375 and 3325 BC) decorated with ostriches, hills and water motifs. The scene depicted on this vase takes us back to an Egypt characterised by a flourishing landscape later changed over time by climatic changes. Ostriches, here painted red, along with elephants, crocodiles, rhinoceros and other wild animals were common in the Nile region at the time.

    The Old Kingdom – A Political/Religious Model Destined for Success and its Weaknesses: The historic period of the Old Kingdom (from the Third to the Sixth Dynasty, roughly between 2700 and 2192 BC) is known for the pyramids and for the consolidation of a bureaucracy at the apex of which stood an absolute sovereign, considered a god on earth and lord of all of Egypt.

    This definition of State and its worldly and otherworldly rules, which were highly elitist, are well documented by funerary objects, of which the Leiden museum has a particularly rich collection, including a calcite (alabaster) table for offerings.

    Offerings to the deceased were a fundamental part of the funerary ritual, ensuring life after death. The uniqueness of this table, which belonged to a high state official named Defdj, lies in its circular shape, which was unusual, as well as the repetition of the concept of the offering as indicated by the inscription, the sculpted receptacles and, most importantly, the central depiction corresponding to the hieroglyph hotep (offering), or a table upon which one places a loaf of bread.

    The Middle Kingdom – The God Osiris and a New Perspective on Life in the Afterworld: The end of the Old Kingdom and the period of political breakdown that followed it led to major changes in Egyptian society, within which the individual had greater responsibility for his own destiny, including in the afterworld. Any Egyptian with the means to build a tomb complete with a sufficient funerary assemblage could now aspire to eternal life. The god Osiris, lord of the afterworld, became Egypt’s most popular divinity.

    Many steles now in Leiden and Bologna came from his temple in Abydos, one of Egypt’s most important cult centres. Among them is that of Aku, major domo of the divine offering, who dedicated the stele to Min-Hor-nekht, the form of the ithyphallic god Min worshipped in the city of Abydos. Aku’s prayer to the god describes an otherworldly existence in a tripartite world: the sky, where the deceased were transfigured into stars, the earth, where the tomb was the fundamental point of passage from life to death, and the beyond, where Osiris granted the deceased eternal life.

    From the Middle to the New Kingdom – Territorial Control at Home and Abroad: The defeat of the Hyksos, ‘princes from foreign lands’ who invaded and governed northern Egypt for a few generations, marked the beginning of the New Kingdom. An extremely aggressive foreign policy enriched Egypt, and this was one of its periods of greatest splendour. The social class of professional warriors rose to the top of the state hierarchy and spawned a number of ruling dynasties.

    The wealth and prestige of these soldiers was also expressed in the production of sophisticated objects, including the gold items attributed to Djehuty, a general under the pharaoh Thutmose III. The Egyptian goldsmith’s art has survived in works of high artistic and economic value, an example being the pectoral element on view in the exhibition.

    This piece is a sophisticated exemplar attributed to the tomb of General Djehuty, the man to whom the sovereign Thutmose III entrusted control of his foreign territories. Representing a blue lotus flower, a symbol of rebirth and regeneration, it must have served as the central element of an elaborate pectoral. The scroll engraved on the back suggests that the piece was given personally by Thutmose III.

    The Saqqara Necropolis of the New Kingdom: The Leiden and Bologna museums can be considered ‘twins’ in a certain sense, since they house two important groups of antiquities from Saqqara, one of the necropolises of the city of Memphis. During the New Kingdom, this early Egyptian capital returned to its role as a strategic centre for the expansionist policy of the sovereigns of the Eighteenth Dynasty.

    This is seen in the funerary monuments of high state officials who held administrative, religious and military roles, including the tombs of the superintendent of Tutankhamen’s royal treasury, Maya, and his wife, Merit, chantress of Amun, and that of Horemheb, head commander of Tutankhamen’s army and the pharaoh’s crown prince.

    The statues of Maya and Merit arrived in the Netherlands in 1829 as part of the collection of Giovanni d’Anastasi. More than a century and a half would pass before, in 1986, a British/Dutch archaeological expedition identified the tomb from which they came, southeast of the pyramid of Djoser at Saqqara. These statues, which are the greatest masterpieces in the collection of the National Museum of Antiquities in Leiden, left the Dutch museum for the first time to be displayed in the exhibition.

    It should be noted that, when the Egypt Exploration Society of London and the National Museum of Antiquities in Leiden began excavation work southeast of the Djoser pyramid in 1975, the goal was to find the tomb of Maya and Merit. It was therefore a great surprise when they instead discovered the burial of General Horemheb, who had capped off his stunning career by becoming the last sovereign of the Eighteenth Dynasty.

    His tomb, which has a temple structure, is characterised by a pylon entrance, three large courts and three cult chapels facing onto the innermost court, which has a peristyle structure. This court is where most of the reliefs preserved in Leiden and Bologna were found, narrating Horemheb’s most important military feats against the populations bordering Egypt: the Asians, Libyans and Nubians.

    The New Kingdom – Prosperity after the Conquest: Refined furnishings, musical instruments, table games and jewellery: these are just a few of the luxury goods attesting to the widespread prosperity enjoyed in Egypt as a result of the expansionist policy of the sovereigns of the New Kingdom. Through these sophisticated objects, it is possible to conjure up moments of everyday life, imagining what it was like living inside a royal palace or the residence of a high official. One example in the exhibition is a mirror handle in the graceful, sensual shape of a young women holding a small bird in her hand.

    Egypt in the First Millennium: In the first millennium BC, Egypt was characterised by the increasingly clear weakness of its central power to the advantage of local governors who gave themselves the role of ruling dynasts. The loss of political and territorial power weakened Egypt’s defence capacity at its borders, opening the way for Nubian, Assyrian and Persian invasions. The temples remained strong centres of power, and managed a sizeable portion of the economy and the transmission of knowledge, taking on the role of a political intermediary between the ruling power and the devout populace.

    Many of the masterpieces on view in the exhibition were part of the funerary assemblages of priests and came from important temple areas. Among them is the sarcophagus of Peftjauneith, which represents the likeness of the god Osiris, wrapped in a linen shroud and with a green face evoking the concept of rebirth. The refined decoration of this sarcophagus confirms the high rank of its owner (the superintendent of the possessions of a temple in Lower Egypt) in the temple sphere. Of particular note is the interior scene of the sky goddess Nut swallowing the sun every evening (to the west) to then give birth to it in the morning (to the east).

    Alexander the Great’s conquest of Egypt in 332 BC ended the ‘pharaonic’ phase of Egyptian history. The period of Greek domination was begun by his successors, the Ptolemies, the last of whom was the renowned Cleopatra VII.

    The golden decline of Egypt would continue for many more centuries, beyond the Roman conquest in 31 BC up to Arab domination in the sixth century AD.

    The dialogue between old and new, local and foreign that distinguished the Greco-Roman period brought a return to high artistic achievements, including the celebrated Fayum portraits, exquisite examples of which from the Leiden collection are on view in the exhibition

  • Scotland: 'Skeletons: Our Buried Bones' at the Hunterian Museum, Glasgow

    Scotland: 'Skeletons: Our Buried Bones' at the Hunterian Museum, Glasgow

    This special exhibition unearths the stories behind four skeletons from the Museum of London’s 20,000-strong collection and four from burial grounds across Scotland. This is a touring exhibition that, after Glasgow, will travel to Bristol and Leeds in 2017, displaying the Museum of London’s skeletons alongside bones discovered locally. In-depth analysis by experts at the Museum of London has provided insights into the health and history of each individual, helping to bring to life the stories that have long been hidden beneath the ground.

    'Skeletons: Our Buried Bones' at the Hunterian Museum, Glasgow

    The skeletons on display in Glasgow reflect a rich and varied past, with individuals coming from diverse locations, both geographically and socially, and periods of time. Excavations have uncovered burial grounds across the UK, ranging from the Neolithic period through the Iron Age to Roman London and up to the 19th century. Each individual skeleton reveals aspects of their life and times, including fractures and trauma, multiple myeloma – cancer, the effects of syphilis, rickets or arthritis, and tooth decay.

    Emily Sargent, curator at Wellcome Collection, said: “Spanning thousands of years and from opposite ends of the country and social scales, the bones of these individuals offer us a rare and special glimpse into history. Yet we identify with their rotten teeth or broken bones, and are reminded that skeletons can tell us more about what people lived with, rather than what they died from.”

    Sharon Ament, Director of the Museum of London, said: “This is the first time our skeletons have gone on tour and really shows how museums at opposite ends of the UK can work together to show their joint collections. We can learn a lot from the bones of our ancestors, who all lived through very different versions of the London we know today, and this is a wonderful opportunity to share their stories alongside those of their local Scottish counterparts for the first time.”


    Research carried out on the skeletons has helped shed new light on the grounds they were discovered in and the circumstances in which they were buried, from plague pits in urban London to the beaches of South Uist. Specially commissioned photographs by photographer Thomas Adank capture the sites as they are now, and will be displayed in the exhibition next to each skeleton, contextualising them as a reminder of the layers of human history all around us.

    Jelena Bekvalac, Curator of Human Osteology at the Museum of London, said: “Research carried out on these skeletons has given us vital clues into the lives of these individuals, some of whom lived thousands of years ago. Putting them in context with where they were buried and what those sites look like now will mean visitors will have a real, tangible connection to these people. It is a unique opportunity for the skeletons from London to be displayed in Glasgow alongside their Scottish counterparts, and truly demonstrates the rich diversity of burial in the British Isles.”

    Professor David Gaimster, Director of The Hunterian, added: “We are delighted to be working in partnership with Wellcome Collection and the Museum of London on this fascinating exhibition. ‘Skeletons: Our Buried Bones’ offers a unique insight into the way people lived, worked and died.”

    ‘Skeletons: Our Buried Bones’ is a collaboration between Wellcome Collection and Museum of London, touring to Glasgow, Bristol and Leeds over 2016-2018. It’s based on ‘Skeletons: London’s Buried Bones’, originally shown at Wellcome Collection in 2008 and is curated by Emily Sargent and Jelena Bekvalac.

  • Palaeontology: Africa’s earliest known coelacanth found in Eastern Cape

    Palaeontology: Africa’s earliest known coelacanth found in Eastern Cape

    Various specimens of Africa’s earliest coelacanth have been found in a 360 million year-old fossil estuary near Grahamstown, in South Africa’s Eastern Cape.

    More than 30 complete specimens of the new fossil species, Serenichthys kowiensis, were collected from the famous Late Devonian aged Waterloo Farm locality, by palaeontologist Dr Robert Gess and described by him in collaboration with Professor Michael Coates of the University of Chicago.

    Gess did the research whilst he was completing his PhD at the Evolutionary Studies Institute at the University of the Witwatersrand. An article describing the new species will be published in the in the prestigious Zoological Journal of the Linnean Society of London on Monday, 21 August.

    “Remarkably, all of the delicate whole fish impressions represent juveniles. This suggests that Serenichthys was using a shallow, waterweed-filled embayment of the estuary as a nursery, as many fish do today,” says Gess.

    The fossils come from black shales originally disturbed by road works at Waterloo Farm. These shales are the petrified compacted remains of mud, which was deposited in the quiet reaches of an estuary not unlike some of those along the Eastern Cape coast today.

    “This earliest known record of a coelacanth nursery foreshadows a much younger counterpart, known from the 300 million year old Mazon Creek beds of Illinois in the United States,” says Gess.

    “This glimpse into the early life history of ancient coelacanths raises further questions about the life history of the modern coelacanth, Latimeria, which is known to bear live young, but whether they, too, are clustered in nurseries remains unknown,” explains Coates.

    360 million years ago, Africa was part of the southern supercontinent Gondwana, made up of Africa, India, Australia, Antarctica and South America. At that time, the rocks of Waterloo Farm were forming along the shores of the semi-enclosed Agulhas Sea, not far from the South Pole.

    Gess originally identified coelacanth remains from the locality whilst carrying out excavations at Waterloo Farm in the mid-1990s under the supervision of Dr Norton Hiller, of the Rhodes University Geology Department. These fossils were not, however, well enough preserved to be reconstructed and described. His painstaking excavation of tons of shale salvaged during subsequent roadworks has now shed light on dozens more specimens, a few of which are preserved in exquisite detail.

    These were prepared under a microscope and have allowed the species to be reconstructed in minute detail. They prove to be a new genus and species.

    Coelacanths are believed to have arisen during the Devonian Period (about 419.2 ± 3.2 million years ago), however only five species of reconstructable Devonian coelacanths have previously been described, in addition to a number of very fragmentary remains. None of these came from Africa, but rather from North America, Europe, China and Australia. The new species gives important additional information on the early evolution of coelacanths.

    “According to our evolutionary analysis (conducted by Gess and Coates), it is the Devonian species that most closely resembles the line leading to modern coelacanths,” says Gess.

    The new species was discovered a mere 100km from the mouth of the Chalumna River, off which the type specimen of Latimeria chalumnae (the first discovered modern coelacanth) was caught in 1938.

    Furthermore, the Geology Department at Rhodes, where Gess was based when he found his first fossil coelacanth, is on the site of the former Chemistry Department where Latimeria was first described. In keeping with the naming of its living relative (after an Eastern Cape river), the species name of the new fossil form, kowiensis, is after the Kowie River which rises among the hills where it was found, and the genus name, Serenichthys, honours Serena Gess, who provided land for the storage of more than 70 tons of black shale rescued from roadworks for ongoing research – in which all the new material was found.

    All specimens have been deposited in the palaeontological collection of the Albany Natural History Museum, in Grahamstown, Eastern Cape Province, South Africa.
