New light shed on ancient Egyptian port and ship graveyard

This obligatory port of entry, known as 'Thonis' by the Egyptians and 'Heracleion' by the Greeks, was where seagoing ships probably unloaded their cargoes to have them assessed by temple officials and taxes extracted before transferring them to Egyptian ships that went upriver. Before the foundation of Alexandria, it was one of the biggest commercial hubs in the Mediterranean because of its geographical position at the mouth of the Nile. The conference will also explore the wider maritime trading economy during the Late Period (664 BC until 332 BC).

The first traces of Thonis-Heracleion were found 6.5 kilometres off today's coastline by the European Institute for Underwater Archaeology (IEASM) under the direction of Franck Goddio in 2000. The Oxford Centre for Maritime Archaeology at the University of Oxford is collaborating on the project with IEASM in cooperation with Egypt's Ministry of State for Antiquities.

In the ports of the city, divers and researchers are currently examining 64 Egyptian ships, dating between the eighth and second centuries BC, many of which appear to have been deliberately sunk. The project researchers say the ships were found beautifully preserved, lying in the mud of the sea-bed. With 700 examples of different types of ancient anchor, the researchers believe this represents the largest nautical collection from the ancient world.

'The survey has revealed an enormous submerged landscape with the remains of at least two major ancient settlements within a part of the Nile delta that was crisscrossed with natural and artificial waterways,' said Dr Damian Robinson, Director of the Oxford Centre for Maritime Archaeology at the University of Oxford. Dr Robinson, who is overseeing the excavation of one of the submerged ships known as Ship 43, will discuss his first findings about the Egyptians' unique shipbuilding style. He will also shed new light on why the boats appear to have been deliberately sunk.

'One of the key questions is why several ship graveyards were created close to the port. Ship 43 appears to be part of a large cluster of at least ten other vessels in a large ship graveyard about a mile from the mouth of the River Nile,' explained Dr Robinson. 'This might not have been simple abandonment, but a means of blocking enemy ships from gaining entrance to the port-city. Seductive as this interpretation is, however, we must also consider whether these boats were sunk simply to use them for land reclamation purposes.'

The port and its harbour basins also contain a collection of customs decrees, trading weights, and evidence of coin production. The material culture, for example, coin weights, will also be discussed at the conference, placing this into the wider narrative of how maritime trade worked in the ancient world.

Elsbeth van der Wilt, working on the project from the University of Oxford, said: 'Thonis-Heracleion played an important role in the network of long-distance trade in the Eastern Mediterranean, since the city would have been the first stop for foreign merchants at the Egyptian border. Excavations in the harbour basins yielded an interesting group of lead weights, likely to have been used by both temple officials and merchants in the payment of taxes and the purchasing of goods. Amongst these are an important group of Athenian weights. They are a significant archaeological find because it is the first time that weights like these have been identified during excavations in Egypt.'

Sanda Heinz from the University of Oxford will share her findings on over 300 statuettes and amulets from the Late and Ptolemaic Periods, including Egyptian and Greek subjects. The majority depict Egyptian deities such as Osiris, Isis, and their son Horus. She said: 'The statuettes and amulets were all found underwater, and are generally in excellent condition. The statuettes allow us to examine their belief system and at the same time have wider economic implications. These figures were mass-produced at a scale hitherto unmatched in previous periods. Our findings suggest they were made primarily for Egyptians; however, there is evidence to show that some foreigners also bought them and dedicated them in temples abroad.'

Franck Goddio, Director of the European Institute of Underwater Archaeology and Visiting Senior Lecturer in Maritime Archaeology at the Oxford Centre for Maritime Archaeology, commented: 'The discoveries we have made in Thonis-Heracleion since 2000 thanks to the work of a multidisciplinary team and the support of the Hilti Foundation are encouraging. Charts of the city's monuments, ports and channels are taking shape more clearly and further crucial information is gathered each year. The conference at Oxford University will present interesting results and might bring new clues and insights of the fascinating history of Thonis-Heracleion."

Franck Goddio will make a comprehensive presentation of the sacred topography of Thonis-Heracleion resulting from12 years of archaeological works on site.
