The Antikythera Mechanism is an ancient Greek mechanical device discovered in 1901 in a shipwreck near the island of Antikythera. Archaeological evidence dates the artifact to approximately 150-100 BCE. The bronze mechanism consists of a complex system of interlocking gears housed within a wooden case, making it the earliest known example of an analog computer.
The device was designed to calculate and predict astronomical phenomena, including the positions of the sun, moon, and planets, as well as lunar and solar eclipses. X-ray analysis and CT scanning have revealed that the mechanism contains at least 37 bronze gears of varying sizes, with some estimates suggesting the original device may have contained over 70 gears. The gear ratios correspond to known astronomical cycles, demonstrating sophisticated mathematical knowledge of celestial mechanics.
One notable component is a spherical element that researchers have identified as representing lunar phases. This feature displays the changing appearance of the moon throughout its monthly cycle by rotating to show varying amounts of a light and dark surface. The mechanism also includes dials that track the Metonic cycle (a 19-year period after which lunar phases repeat on the same calendar dates) and the Saros cycle (an 18-year period used to predict eclipses).
The technological complexity of the Antikythera Mechanism indicates that ancient Greek craftsmen possessed advanced knowledge of precision engineering and gear systems. No comparable mechanical device from antiquity has been discovered, though historical texts suggest similar instruments may have existed. The artifact provides evidence of sophisticated scientific and mathematical understanding in the Hellenistic period.
