Discovery of the Antikythera Mechanism

The Antikythera mechanism, salvaged in 1901 after lying on the seabed for over 2,000 years, is an ancient device made of bronze and gears that revolutionized our understanding of pre-modern technology. Initially misidentified as a mere lump of corroded metal, it was uncovered from a shipwreck discovered by Greek sponge divers near Antikythera Island, which was on a common trade route. This mechanism was characterized as an ancient analogue computer, sophisticated enough to model celestial movements, including those of the sun, moon, and planets, thereby challenging assumptions about the technological capabilities of ancient cultures. The device contained dials for predicting eclipses and tracking athletic events, showcasing a blend of astronomical knowledge and societal interests of that era.
