Antikythera Mechanism: The Ancient Sky Computer from a Shipwreck

A lump of corroded bronze from a shipwreck turned out to be the Antikythera Mechanism, an ancient sky computer that could track the Sun, Moon, eclipses, and calendar cycles. In this episode, we unpack how Greek astronomy, gears, and a 2,000-year-old mystery came together in one astonishing artifact—and why it changes what we think ancient technology could do. Listen now to hear how a wreck at sea became one of history’s smartest discoveries.

The Antikythera Mechanism is one of archaeology’s strangest and smartest discoveries: a 2,000-year-old Greek bronze device found in a shipwreck that could model the Sun, Moon, eclipses, and calendar cycles.
