Lego Antikythera Mechanism

This ancient machine was discovered by divers in 1908 off the coast of Antikythera. Coverd in corrosion the purpose of the device remained a mystery for almost 100 years. Through the use of X-Rays and CAT scans scientists were able learn that the device was an extremely accurate computer used by the Greeks to predict eclipses and other celestial events.

It is an analog computer with over 100 gears and 7 differential gearboxes. It is accurate to a day or two over it’s range.

Five turns of the central yellow handle advances the machine one year. The dials on the left represent the Saros cycle of lunar months. The dials on the right represent the positions of the sun and moon against the zodiac.
