Antikythera wreck

The Antikythera wreck is a shipwreck that was discovered by sponge divers off the coast of the Greek island, Antikythera. Its approximate location is 35° 53' 23" (35.8897)N and 23° 18' 28" (23.3078)E, "20m off Point Glyphadia".

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 sail back from Africa on the island of Antikythera, and they began diving for sponges off the island's coastline. Although in years past divers worked naked, by 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 60 metres down was Elias Stadiatos, 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 had gone mad from too much carbon dioxide in his helmet, Kondos himself dove into the water, soon returning with a bronze arm of a statue. Until they could safely leave the island, the divers dislodged as many small artifacts as they could carry.

Together with the Greek Education Ministry and Hellenic Navy, the sponge divers salvaged numerous artifacts from the waters. By the end of 1902, divers had recovered statues of a philosopher's head, a young boy, a discus thrower, the bronze Antikythera Ephebe of "ca." 340 BC (now in the National Archaeological Museum of Athens), a Hercules, a marble bull and a bronze lyre. Many other small and common artifacts were also found. On May 17, 1902, however, archaeologist Valerios Stais made the most celebrated find. When diving to search the area of the wreck, he noticed that one of the pieces of rock near him had a gear wheel embedded in it. It would soon be identified as the Antikythera mechanism; originally thought to be one of the first forms of a mechanised clock, it is now considered to be the world’s oldest known analog computer.

Dating the ship

Although the retrieval of artifacts from the shipwreck was highly successful and accomplished in two years, dating the site proved difficult and took much longer. Based on related works with known provenances, some of the bronze statues 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 amphoras 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.

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 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 convincingly 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.
