The Antikythera Mechanism: Mathematical Astronomy through Ancient Gears

In 1901, heavily corroded fragments of a gearwork mechanical device were recovered from the site of a Greek shipwreck dating to around 60 BCE, close to the island of Antikythera. Research carried out over the past 60 years, using progressively more powerful imaging techniques, has resulted in a secure, if not quite complete, reconstruction of the Antikythera Mechanism as a chronological and astronomical simulator that displayed cycles of time and apparent motions of the heavenly bodies at a highly accelerated rate relative to real time. In this talk I will focus on the assumptions originating in Greek mathematical astronomy and Greek society that were built into the Mechanism, and on how these assumptions were implemented in the gearwork.
