History of underwater archaeologyAlready during the time of Herodotus, the Greek historian, people were fascinated by past civilizations. During the Middle Ages in Europe there was a widespread belief in a Golden Age, when things supposedly had been much better. To those people, Ancient Rome and Greece represented that lost Golden Age.
Early salvage and diving
The interest in maritime finds was awoken by the find of the Nemi Ships in the 15th century. After that, very little happened until the invention of helmet diving in the early 19th century.
Using helmet divers the wreck of Royal George (1782) was salvaged around 1830, but not for archaeological reasons.
In 1836 the Dean brothers discovered the wreck of Mary Rose, and salvaged a few objects. Perhaps this is the first case of underwater investigations, made of historical interest. Also, in 1856 the submerged settlement in the Zürich Lake was investigated by divers and historians.
The diving archaeologist
During the following 70 years, many historic ships were salvaged (pillaged) by divers, but only for commercial reasons. The valuables were sold, and a museum would get the rusty iron cannon or minor objects such as Roman lead anchors. But there was no archaeological investigation.
The first systematic archaeological underwater investigation was probably the recovery of the Nemi Ships in 1929-32.
The first case of diving underwater archaeology may have been 1933-39 when the Swedish warship Elefanten (1564) was investigated by helmet divers together with historians.
The breakthrough came after World War II. Thanks to the scuba diving equipment developed by Emile Gagnan and Jacques-Yves Cousteau, the underwater world became instantly accessible, and many new ancient wrecks were found at a rapid pace.
A pilot case for archaeology with scuba divers was the Grand Congloué wreck in France, investigated 1951-57 by Cousteau and Fernand Benoît. When the divers started digging down in the layers covered by sand, they first thought it was one wreck, while in fact it was two wreck on top of each other.
After the Grand Congloué, many underwater archaeology investigations have been made, by poineer archaeologists such as Nino Lamboglia, George F. Bass, Peter Throckmorton, and many others.
The methods have been improved – slowly and tediously even the smallest objects are recorded, as clues to our understanding of people from times past.
Even though Cousteau was not an archaeologist, he contributed immensely by promoting popular interest for underwater mysteries.
The future?
The problem is time and money. Underwater archaeology, like most aspects of education and culture, can never survive on a pure commercial basis.
Only a few sites can be investigated, while others are left untouched for the future. Leaving sites for the future is an excellent idea in theory. But in reality they risk being robbed by treasure hunters.
Should police and military be more vigilant watching heritage sites, on land and underwater?
Or can a site be investigated together with commercial interests, perhaps selling some of the objects?
That is the issue of today.
