The Antikythera Mechanism is an ancient Greek analog computer that was discovered in 1901 in a shipwreck off the island of Antikythera. It is over 2,000 years old and is believed to have been used to predict astronomical positions, track the movements of the Sun and Moon, and predict solar and lunar eclipses. The mechanism consists of a system of several complex gears and is considered one of the earliest known examples of a mechanical computer.
