The Antikythera wreck in the Aegean Sea is a world-famous underwater archaeological site thrown into the spotlight in 1900 when researchers discovered an incredible mechanical device, now known as the Antikythera mechanism, which dates back 2,000 years. The device consists of a complex combination of gears and took decades for scientists to decipher its functionality – it shows the positions of the sun, moon, and planets as they move through the zodiac, predicts solar and lunar eclipses, and even marked key events such as the Pan-Hellenic games.
