The '''Antikythera mechanism''' was recovered from an ancient shipwreck off the [[Greece|Greek]] island of Antikythera in 1900. Thought to be over 2,000 years old, [[gamma ray]] analysis has revealed an intricate [[astronomy|astronomical]] device utilising "calibrated differential gears"<ref>http://ccat.sas.upenn.edu/rrice/usna_pap.html</ref> and capable of predicting the movements of the [[sun]] and [[moon]]. Remarkably, it pre-dates instruments of similar complexity by around a thousand years.
