A discovery, a revelation!

A shipwreck off the island of Antikythera, a coincidental dive in the area in 1900 and a series of coincidental events, brought to light the most ancient computer in the world.

Astronomy professor of AUTH John Seiradakis, a charismatic speaker, presented the impressive findings of the Antikythera mechanism, the first analog computer. Made from at least 30 precise cooperating gears, it calculated known astronomical cycles, such as Meton’s and Saros cycle, predicted solar and lunar eclipses, planet movements and the dates of ancient sacred (“stephanos”) games (such as Olympia, Isthmia, Nemea, Pythia and Naia). Coins found depict that the shipwreck dates from 85 to 67 BC. However, it seems that the mechanism was constructed before that, around 150-100 BC.

Exploration never stops. The Antikythera mechanism has more secrets to reveal…

Thank you professor John Seiradakis for the excellent lecture and all of you for attending!
