The chance discovery in 1900 of an ancient shipwreck off the greek island of antikythera led to the recovery of some corroded fragments of what turned out ot be the earliest known example of precision gearing. our illustrated talk will tell a fascinating story of how the combined efforts of archaeologists,, historian\s of science and the latest imaging techonoogy have led to the reconstruction of an ancient greek geared calendar-computer and a complete revision of our views of greek techonology. from this mechanism we will follow the history of precision gearing through the islamic medieval period, including the geared astrolabes of al-briuniand muhammad ibn AbiBakrof isfahan, which contain many features similar to those in the antikythera mechanism .
