In 1901, sponge divers found a strange device off the coast of the Greek island of Antikythera in the Aegean Sea. The device is a wooden box with a complex system of gears and a hand crank. Analysis on the device showed that it dates back to the 1st or 2nd centuries BCE. As out-of-place as it seems, the Antikythera Mechanism is an ancient analogue computer that predates Apple Computers by centuries. Most experts believe that the Antikythera Mechanism was used to predict astronomical positions, like eclipses.
