The wreck manifested numerous statues, coins and other artifacts dating back to the 4th century BC, as well as the severely corroded remnants of a device that is called the world's oldest known analog computer, the Antikythera mechanism. Coordinates:
Discovery and artifact recovery
In October 1900, a team of sponge divers led by Captain Dimitrios Kondos had decided to wait out a severe storm hampering their return from Africa at the Greek island of Antikythera, and while there they began diving for sponges off the island's coastline. In 1900, divers usually wore standard diving dresses — canvas suits and copper helmets – which allowed them to dive deeper and to stay submerged longer.
The first to lay eyes on the shipwreck 45 meters down was Elias Stadiatis, who quickly signaled to be pulled to the surface. He described the scene as a heap of rotting corpses and horses lying on the sea bed. Thinking the diver was drunk from the nitrogen in his breathing air at that depth, Kondos himself dived, soon returning with a bronze arm of a statue. While waiting for the storm to abate, the divers retrieved as many small artifacts as they could from the wreck.
Together with the Greek Education Ministry and the Royal Hellenic Navy, the sponge divers salvaged numerous artifacts from the waters. By the middle of 1901, divers had recovered statues arbitrarily named "the philosopher", the Youth of Antikythera (Ephebe) of ca. 340 BC, a "Hercules", Ulysses, Diomedes and his horses, an Ermes, an Apollo, a marble statue of a bull and a bronze lyre, lots of marvelous glasswork. Many other small and common artifacts were also found and were brought to the National Archaeological Museum of Athens.
The death of one diver while some others were paralyzed from decompression sickness put an end to work at the site during the summer of 1901. The French naval officer and explorer Jacques-Yves Cousteau would later dive there, in the fall of 1976, to search and recover many more artefacts.
On 17 May 1902, however, the former Minister of Education Spyridon Stais made the most celebrated find at the National Archaeological Museum in Athens. When examining the artifacts that had been recovered, he noticed that a severely corroded piece of bronze had inscriptions and a gear wheel embedded in it. The object would come to be known as the Antikythera mechanism or astrolabe. Originally thought to be one of the first forms of a mechanised clock or an astrolabe, it is at times referred to as the world’s oldest known analog computer. although it is technically an advanced mechanical calculator.
Dating the ship
Although the retrieval of artifacts from the shipwreck was highly successful and accomplished within two years, dating the site proved difficult and took much longer. Based on related works with known provenances, some of the bronze statues could be dated back to the 4th century BC, while the marble statues were found to be 1st century BC copies of earlier works.
Some scholars have speculated that the ship was carrying part of the loot of the Roman General Sulla from Athens in 86 BC, and might have been on its way to Italy. A reference by the Greek writer, Lucian, to one of Sulla's ships sinking in the Antikythera region gave rise to this theory. Supporting an early 1st-century BC date were domestic utensils and objects from the ship, similar to those known from other 1st-century BC contexts. The amphorae recovered from the wreck indicated a date of 80–70 BC, the Hellenistic pottery a date of 75–50 BC, and the Roman ceramics were similar to known mid-1st century types. The latest coin discovered in the 1970s during work by Jacques Cousteau and associates is datable between 76 and 67 BC. It has been suggested that the sunken cargo ship was en route to Rome with looted treasures, to support a triumphal parade being planned for Julius Caesar.
Remains of hull planks showed that the ship was made of elm, a wood often used by the Romans in their ships. Eventually in 1964 a sample of the hull planking was carbon dated, and delivered a calibrated calendar date of 220 BC ± 43 years. The disparity in the calibrated radiocarbon date and the expected date based on the ceramics and coins was explained by the sample plank originating from an old tree cut much earlier than the ship's sinking event.
Further evidence for an early 1st-century BC sinking date came in 1974, when Yale University Professor Derek de Solla Price published his interpretation of the Antikythera mechanism. He argued that the object was a calendar computer. From gear settings and inscriptions on the mechanism's faces, he concluded that the mechanism was made about 87 BC and lost only a few years later.
In 2012, marine archeologist Brendan P. Foley of the Woods Hole Oceanographic Institution in the United States received permission from the Greek Government to conduct new dives around the deep shoals of Antikythera. The divers began a preliminary three-week survey in October 2012 using SCUBA rebreather technology, to allow for extended dives down to a depth of 70 metres (230 ft). This new diving technology will now allow a fuller, complete survey of the Antikythera Wreck site, which was not previously conducted. Additionally, the divers were to search deeper down a slope adjacent to the wreck's debris field in order to try and locate other artifacts that may have moved there over the past two millennia due to the actions of storms and currents. Foley will be conducting the search with other archaeologists including Theotokis Theodoulou of the Greek Ephorate of Underwater Antiquities.
Any new artifacts found might help identify the Roman galley ship that sank and provide further insight into its voyages and manifests, and the researchers are hoping to find other small pieces of the Antikythera Mechanism on the sea floor, although the chances of that occurring are considered very slim. Additionally they hope to locate and survey other shipwrecks that foundered on the island's shoals, including the wreck of the British warship HMS Nautilus which sank in 1807 at the island and which was located there in June 2012. The new expedition, named "Return to Antikythera", is scheduled for 2014.
New artifacts were recovered from the site in 2013.
