Aphrodite's Computer: The Antikythera Mechanism

Perhaps the most extraordinary surviving relic from the ancient Greek world is a device containing over thirty gear wheels dating from the 1st century B.C. and now known as the Antikythera Mechanism.

This device is an order of magnitude more complicated than any surviving mechanism from the following millennium, and there is no known precursor. It is clear from its structure and inscriptions that its purpose was astronomical, including eclipse prediction.

Image of the Antikythera Mechanism on display at the National Archaeological Museum, with conservator Gerassimos Makris.In this illustrated talk, Mike Edmunds (Emeritus Professor of Astrophysics at Cardiff University) will outline the results, including an assessment of the accuracy of the device - from the international research team, which has been using the most modern imaging methods to probe the device and its inscriptions. Their results show the extraordinary sophistication of the Mechanism's design.

The event is free and no ticket is required. The lecture is suitable for all ages so why not come along?
