A mechanical instrument made from bronze and wood in ancient Greece was a calendar for predicting solar eclipses and the dates of the Olympic Games, scientists have discovered.
X-ray analysis of the device, known as the Antikythera Mechanism, has revealed that it marked the timing of sporting events around Greece – including at Olympia. It was made in the 2nd century BC. The device was found by sponge divers in 1900 off the island of Antikythera.

The mechanism ran on a complicated set of dials and bronze gears and was decorated with elaborate but indiscernible inscriptions.
