Antikythera mechanismThe Antikythera mechanism is a mechanical device recovered in 1901 from an ancient shipwreck near the Greek island of Antikythera. It dates from approximately 100 BC.
Preserved in the National Archaeological Museum in Athens. The mechanism contained 37 bronze gears in a wooden case on which were placed dials with hands and was reconstructed as being used to calculate the movement of celestial bodies. Other devices of similar complexity are unknown in Hellenistic culture.
