The Great London:
Underwater Archaeology

The British Museum is to stage a major exhibition on two lost Egyptian cities and their recent rediscovery by archaeologists beneath the Mediterranean seabed. Opening in May 2016 for an extended run of six months, The BP exhibition Sunken cities: Egypt’s lost worlds will be the Museum’s first large-scale exhibition of underwater discoveries. It will show how the exploration of Thonis-Heracleion and Canopus – submerged at the mouth of the River Nile for over a thousand years – is transforming our understanding of the relationship between ancient Egypt and the Greek world and the great importance of these ancient cities.

300 outstanding objects will be brought together for the exhibition including more than 200 spectacular finds excavated off the coast of Egypt near Alexandria between 1996 and 2012. Important loans from Egyptian museums rarely seen before outside Egypt (and the first such loans since the Egyptian revolution) will be supplemented with objects from various sites across the Delta drawn from the British Museum’s collection; most notably from Naukratis – a sister harbour town to Thonis-Heracleion and the first Greek settlement in Egypt.

Likely founded during the 7th century BC, Thonis-Heracleion and Canopus were busy, cosmopolitan cities that once sat on adjacent islands at the edge of the fertile lands of the Egyptian Delta, intersected by canals. After Alexander the Great’s conquest of Egypt in 332BC, centuries of Greek (Ptolemaic) rule followed. The exhibition will reveal how cross-cultural exchange and religion flourished, particularly the worship of the Egyptian god of the afterlife, Osiris.

By the 8th century AD, the sea had reclaimed the cities and they lay hidden several metres beneath the seabed, their location and condition unclear. Although well-known from Egyptian decrees and Greek mythology and historians, past attempts to locate them were either fruitless or very partial. The exhibition will show how a pioneering European team led by Franck Goddio in collaboration with the Egyptian Ministry of Antiquities made use of the most up-to-date technologies to find them.

Thanks to the underwater setting, a vast number of objects of great archaeological significance have been astonishingly well preserved. Pristine monumental statues, fine metalware and gold jewellery will reveal how Greece and Egypt interacted in the late first millennium BC. These artefacts offer a new insight into the quality and unique character of the art of this period and show how the Greek kings and queens who ruled Egypt for 300 years adopted and adapted Egyptian beliefs and rituals to legitimise their reign.

The exhibition will feature a number of extraordinary, monumental sculptures. A 5.4m granite statue of Hapy, a divine personification of the Nile’s flood, will greet visitors as they enter the space. Masterpieces from Egyptian museums such as the Apis bull from the Serapeum in Alexandria will be shown alongside magnificent recent finds from the sea. One such piece is the stunning sculpture from Canopus representing Arsinoe II (the eldest daughter of Ptolemy I, founder of the Ptolemaic dynasty). The Graeco-Macedonian queen became a goddess beloved to both Egyptians and Greeks after her death and is depicted here as the perfect embodiment of Aphrodite, a goddess of beauty ‘who grants fortunate sailing’.

The exhibition will also cover the arrival of Greeks in Egypt, when they were hosts and not rulers; privileged but controlled by the pharaohs. A complete stela from Thonis-Heracleion advertises a 380BC royal decree of the Egyptian pharaoh Nectanebo I. It states that 10% of the taxes collected on all goods imported from the ‘Sea of the Greeks’ into Thonis-Heracleion and on all trade operations at Naukratis were to be donated to an Egyptian temple.

A wide range of objects, from modest to grand and costly, bears witness to the piety of both inhabitants and visitors at these major religious centres. Lead models of barges uncovered in the sacred waterway linking Thonis-Heracleion to Canopus are unique and moving finds. They are associated with the Mysteries of Osiris, the most popular festival celebrated annually across Egypt during the month of Khoiak (mid-October to mid-November). Ranging in size from 6 to 67cm, these reproduce in metal a flotilla of 34 papyrus barges that would have been displayed on a waterway to celebrate the first sacred navigation of the festival. According to religious texts, each barge was to measure 67.5 cm and to bear the figure of an Egyptian god, and would have been illuminated by 365 lamps. The lead barges are lasting testimonies possibly left by people who, long ago, celebrated this festival in the Canopic region.

Only a tiny proportion of these sites have revealed their secrets. The on-going underwater archaeological mission continues to bring to light new masterpieces and further research every year as the most recent finds from 2012 will show.

Sir Richard Lambert, Chairman of the British Museum, said, “It’s hugely exciting to be announcing the British Museum’s first large-scale exhibition of underwater discoveries and to be welcoming these important loans to London. We are grateful to BP for their ongoing support without which ambitious exhibitions such as these would simply not be possible. We’re also delighted to be working with Franck Goddio, his expert team at IEASM, the Hilti Foundation and of course our Egyptian colleagues to bring the extraordinary story of these lost cities to life.”

His Excellency Nasser Kamel, Ambassador of the Arab Republic of Egypt to the United Kingdom, said, "As well as looking for partners to invest in the Egyptian economy, Egypt is always searching for partners to help in exploring its heritage and treasures which are still hidden under its lands, and waters. This exhibition shows that despite what we know of its tremendous history and culture, Egypt still has a lot more to offer to?the world and we thank our partners in the UK, such as BP, for working with us in utilising our resources to develop our economy and through such an exhibition unraveling our history as well. I invite the people of Britain to visit this exhibition to get a glimpse of what Egypt has to offer, and come to Egypt to live that experience."

Bob Dudley, Group Chief Executive, BP, said, “BP is proud to support this fascinating exhibition which showcases the power of science and the pioneering spirit to discover what lies beneath the surface of the Nile Delta. By sharing these underwater treasures the British Museum is opening a whole new frontier for visitors to explore, and we are pleased to be a part of it.”

Franck Goddio, President of Institut Europeen d’Archeologie Sous-Marine (IEASM) and exhibition co-curator said “My team and I, as well as the Hilti Foundation, are delighted that the exhibition with discoveries from our underwater archaeological expeditions off the coast of Egypt will be on display at the British Museum. It enables us to share with the public the results of years of work at the sunken cities and our fascination for ancient worlds and civilisations. Placing our discoveries alongside selected masterpieces from the collections of Egyptian museums, complemented by important objects from the British Museum, the exhibition presents unique insights into a fascinating period in history during which Egyptians and Greeks encountered each other on the shores of the Mediterranean.”

Aurelia Masson-Berghoff, exhibition curator at the British Museum said “People sometimes assume that when two cultures mix, the essence of each is diluted and, as a result, weakened; this exhibition demonstrates the opposite. It is a rare opportunity to reveal the beauty and strength of Late Pharaonic art and culture, alongside the latest research on the momentous intermingling between Egyptian and Greek communities in Egypt at this time. We are illustrating this vibrant cosmopolitan world through Egyptian, Greek and ‘hybrid’ artworks, rarely ever displayed side by side. It shows ancient Egypt not as an isolated civilisation, but as the outward looking, influential and inclusive society that it was.”

The wreck of a former slave ship lying just off the coast of Perth is being scoured by maritime archaeologists using new technology to revisit earlier excavations and help learn more about Australia's underwater past.

The site of the James Matthews is being photographed to create a detailed three-dimensional model of the shipwreck.

It is hoped the work will eventually help determine new ways of protecting it and other shipwrecks as well as ways to test new techniques and methods.

"The colours and details are really accurate," the WA Maritime Museum's Madeline McAllister said.

"Whereas in the past we would have taken some photos to create a 2D site plan and then also done the measurements ourselves with tapes, so [it was] not quite as accurate as what we're getting with these 3D models."

The James Matthews was first discovered in 1973 lying largely buried in sand in shallow waters two-to-three-metres-deep, less than 200 metres off Woodman Point, just south of Fremantle.

It had sunk there after slipping its anchor during a storm and hitting rocks in July 1841.

At the time, the snow brig was a merchant vessel, and had travelled from London laden with farm equipment and construction material for the newly established Swan River colony.

But archaeologists, who first excavated the ship in the 1970s led by former director of the WA Maritime Museum Graeme Henderson, soon discovered its link to the horrific trans-Atlantic slave trade.

It had previously been called the Don Francisco and was owned by a notorious and powerful Brazilian-born slave trader called Francisco Felix de Souza, who operated out of West Africa and was involved in power plays with leaders of the Kingdom of Dahomey, in present day Benin.

The Don Francisco was seized in 1837 off the island of Domenica as it headed towards Cuba by the British, who had passed an act abolishing the slave trade three decades earlier.

The British sailors found 433 slaves crammed inside the 24.5-metre hull.

The ship should have been destroyed under the law of the time, but was instead repaired and renamed the James Matthews, a London-registered merchant vessel — paving the way for its eventual demise.

When it was wrecked off Woodman Point, the ship fell on its side and buried much of its cargo and rigging in the sand.

That helped preserve the artefacts.

"In the case of the James Matthews, it went into sand and the sand buried it with the shifting currents and so forth, and so basically most of the ship was still there. Wonderful," Dr Henderson said.

"The sand gives them an anaerobic environment, which means no oxygen, which means not much in the way of deterioration had taken place.

A leather shoe, a parasol with much of the lace preserved, an ivory chess set, and pulleys with rope still largely intact, were some of the surprisingly well-conserved artefacts discovered.

Intriguingly, the part-owner of the ship at the time, Henry de Burgh, later wrote 200 gold sovereigns were also lost to the sea, supposedly never recovered.

Former WA Maritime Museum director Graeme Henderson, who has officially retired but still spends his days hunting shipwrecks, said the 3D modelling would help gain a better understanding of the site over time.

"The idea is we will come back very few years and take another set of photographs and be able to overlay the models," he said.

"And you'll see growth in seaweed and sponges on the site and you'll also be able to see the deterioration if that's happened."

WA Museum maritime archaeology curator Ross Anderson said a lot of underwater cultural heritage sites, including shipwrecks like the James Matthews and prehistoric sites, were "out of sight and out of mind".

"If people don't see them, they don't see the importance, so these kinds of visualisations and interpretations convey to people what's under there, what's under the water, what's under the sand, [and that it's] actually really important and worth preserving," Dr Anderson said.

In one of the biggest operations of its kind, archaeologists have succeeded in lifting a perfectly preserved 17th century English gun-carriage from the bottom of the Thames estuary.

It had been discovered in the wreck of the English warship, the London, built by Oliver Cromwell’s government in the 1650s.

The  1.6 metre long, 70 centimetre wide piece of artillery equipment would originally have held a 9 foot long cannon, capable of firing 24 pound cannon balls up to two miles.

The gun carriage has just been recovered with the help of a crane on-board a giant barge. The operation has been funded by Historic England.

Archaeologists will now study the carriage to try to determine whether the gun it held is one of those still believed to be on or under  the seabed or whether it is one of the few that have already been brought to the surface.

Specialists will also examine the carriage  to discover what wood it was made of. Elm was preferred by the navy because it splintered less in combat and therefore reduced casualties. However in the 1650s, Dutch elm disease massively reduced the availability of elm wood in England – and naval carpenters in the late 1650s and the rest of that century  were forced to use oak instead when making gun carriages.

The London broke in two and sank when the vessel exploded two miles off Southend, Essex in 1665.

“The newly raised gun carriage is a very important find and  in remarkable condition” said Charles Trollope, a leading expert in 17th century naval artillery.

Apart from a naval gun carriage at Windsor Castle, the newly raised artefact is the only known well-preserved example in existence. However it is  possible  that other well-preserved gun carriages still survive buried on the wreck site.

Its recovery has saved it from being destroyed by changing currents and sea worms that are increasing in English waters because of climate change.

Much of the archaeological investigation of the London wreck site has been carried out by volunteer divers from Southend. The newly raised gun carriage will now begin a long period of conservation.

Alison James, a Historic England maritime archaeologist, said: “This 350 year old gun carriage is in near-perfect condition. It’s a national treasure and the key to new knowledge of our social and naval history. We had to recover it quickly or it would have broken up and been lost forever.

“It’s complete with all the implements that the gunner would have used to make the cannon fire – all the archaeological material is there with it so it’s hugely exciting. Until now, it’s been well preserved, enclosed in an anaerobic environment, oxygen-free mud, safe from all the creepy-crawlies that would normally erode it.  We’ve even got the 350 year old rope going through the pulley block. But as parts of the gun carriage recently became exposed, we had to act fast to save this rare piece of our history from the ravages of the waves and biological attack,” she said.
