During the 19th century, hunger and lack of expectation were so common in Greece that many were forced to engage in farming. sponge fishing. It was a profitable business, yes; but very dangerous. The divers had to dive into the sea with large stones attached to their bodies and throw them away (loaded as much as they could gather just before surfacing) when they ran out of air.

Around 1869, the introduction of the first diving suits increased production, but it also increased risks (and human lives). In the long history of economic development, money and death often go hand in hand. The ships left the Aegean at Easter and returned in the autumn for the Eastern Mediterranean and North Africa. So we know that the Antikythera shipwreck was found a few days after Easter 1900..

A treasure in the middle of the Mediterranean

Captain Dimitrios Kondos’ ship left Symi for Easter and took refuge in Antikythera, between Crete and the mainland, on its way to African fishing, when the wind lost its favor. They took advantage of the stall to practice their copper diving suits and teach new divers; some entertained themselves by holding competitions to see who could come in the lowest. We know that for example Elias Stadiatis descended to a depth of 45 meters.

After resurfacing, Stadiatis began to speak of “decaying corpses and horses scattered among the rocks on the seafloor,” and sailors began to worry that he had been exposed to nitrogen poisoning while diving. But he held fast to his weapons, and before he went to Africa, Kondos went down to check that it was just a mirage..

It took a long time. It took so long that the sailors grew impatient, and just as they were about to start pulling him up, Kondos signaled them to go up. He brought with him the arm of a bronze statue. The wind had changed, they had to go. But when they returned last year, they pulled many things out of the water and, given the extent of the discovery, notified Athens. The first serious work to save the Antikythera shipwreck began in 1900. and they lasted through 1901. Here we found the ‘mechanism’, the oldest (analog) computer we know of.

A door to the past…

Since then Antikythera an inexhaustible source of information On the “history, economy, technology and art” of ancient Greece and Rome. And yet, only some of the wreckage is accessible. The exact moment is unclear, but the shipwreck must have sunk in the first century. Shortly after, an earthquake ‘locked’ most of the treasures under rocks weighing up to eight and a half tons.

The problem is, for decades, divers have pulled things out of Antikythera’s waters without a plan or concert. No one documented where the mechanism was found, where the statues or relics were found. Definitely, no one knows what the shipwreck looks like, no one knows exactly which rock to look for.

And how it’s not easy to call (Currently, divers can only spend half an hour at the wreck site after a 15-minute descent and just before surfacing), not knowing what the wreck was like is a serious problem. It is a serious problem that has been tried to be solved with the world’s most advanced mapping systems in recent years.

…it’s also a door to the future

Since 2012, encouraged by the work of Brendan P. Foley, archaeologists from the University of Venice, the Swiss School of Archeology in Greece and the University of Lund in Sweden have thoroughly re-examined the waters of Antikythera and are working on techniques for doing so. 3D mapping that allows not only to better understand the design of the wreck, but also to learn more about the ship in question (its age, origin and destination).

They are not bad: for now, their efforts have brought the head of a large statue of Hercules to the surface, and gradually, 3D maps make sense of the Antikythera shipwreck. But this is the beginning of something bigger: the historic site is becoming a major laboratory for new underwater archeology techniques.

In an environment where everything costs up to five times more, mechanisms are not put in place to manipulate deposits (and remove huge stones); but the first robots are already being used and they promise a complete paradigm shift. Again, looking to the past is often the best way to see a better future.
