Ancient calculator on display at Archaeological museum


An exhibition entitled "The wreck of Antikythera - The ship, the treasures, the Mechanism", will open at the Archaeological Museum in Athens on April 5 and will run for a year.



This is the first time that all the findings from the Antikythera wreck, dated between 60-50 BC, will be displayed together, while some of the items have never been displayed before.



Sometime before Easter 1900, Elias Stadiatis, a Greek sponge diver, discovered the wreck of an ancient cargo ship off Antikythera Island at a depth of 42 m (138 ft). Sponge divers retrieved several statues and other artifacts from the site.



The Mechanism itself was discovered on May 17, 1901, when archaeologist Valerios Stais noticed that a piece of rock recovered from the site had a gear wheel embedded in it. Examination revealed that the "rock" was in fact a heavily encrusted and corroded mechanism that had survived the shipwreck in three main parts and dozens of smaller fragments.



The device itself was surprisingly thin, about 33 cm (13 in) high, 17 cm (6.7 in) wide, and 9 cm (3.5 in) thick, made of bronze and originally mounted in a wooden frame. It was inscribed with a text of over 2,000 characters, many of which have only just recently been deciphered.



The Antikythera Mechanism is believed to be an ancient mechanical calculator (also described as a "mechanical computer") designed to calculate astronomical positions. It was discovered in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to about 150-100 BC. Technological artifacts of similar complexity appeared a thousand years later. (ΑΜΝΑ)
