THE ANTIKYTHERA MECHANISM
Ancinent Greece - Byzantium, History & Culture2,000 years ago Greek engineers built a unique mechanism that, following 25 years of study, was found to be an astronomical instrument of great importance. A set of 30 different gears provided information about the movements of the Sun, Moon and planets in the Zodiac. It is the Antikythera mechanism, the first computer in world history, a remarkable testimony to the great technological and mechanical evolution that reached its apex in 80 B.C. with the construction of this mechanism. Both the computer and its successor, the Byzantine sundial/calendar, are examined and analyzed for the first time as to the full extent of their influence, while the possibilities of a mechanical revolution during the Hellenistic period are highlighted. These two mechanisms, both of which included a differential gear, sealed the history of mechanical evolution for 2,000 years.
