The Antikythera Mechanism
The Antikythera mechanism, an ancient Greek analog computer used to predict astronomical positions and eclipses, dates to around 100 BC. This intricate device consisted of gears and was capable of complex calculations related to celestial events. Discovered in a shipwreck off the coast of Antikythera, Greece, the mechanism is considered one of the earliest known examples of a geared device used for computation.
