In the summer of 1901, a mysterious contraption was diacivered deep underwater in a ship in the Greek island Antikythera. Since it's Discovery, the  Antikythera mechanism has often been referred to as the world's first known analog computer. Using technology that was lost to antiquity until the 14th century, this baffling mechanism was allegedly used to predict astronomical positions and eclipses, as well as the 4-year cycle of the Olympic games.
