The Antikythera Mechanism is an ancient Greek mechanical device discovered in 1901 in a shipwreck near the island of Antikythera. Dating to approximately 100-50 BCE, the bronze mechanism consists of at least 37 meshing bronze gears housed within a wooden case. Archaeological evidence indicates it functioned as an astronomical calculator capable of predicting the positions of the sun, moon, and known planets, as well as lunar and solar eclipses.
Users could input a date by turning a hand crank, which would display corresponding astronomical information on multiple dials. The mechanism incorporated the 19-year Metonic cycle for lunar calculations and could predict eclipses decades in advance using the 223-month Saros cycle.
Research conducted using advanced imaging techniques, including X-ray tomography, has revealed inscriptions and gear ratios that demonstrate sophisticated mathematical knowledge. The mechanism’s gear trains achieve ratios that closely approximate known astronomical periods, indicating precise understanding of planetary motion. This level of mechanical complexity was not seen again in surviving artifacts until the development of astronomical clocks in medieval Europe, suggesting either a lost tradition of ancient mechanical engineering or the exceptional nature of this particular device.
