The Antikythera mechanism is a corroded bronze device recovered in 1901 from a Roman-era shipwreck off a small Greek island. Built in the second century BC, it used dozens of interlocking gears to model astronomical cycles. By turning a hand crank, an operator could track the positions of the Sun and Moon, predict eclipses, and even follow the four-year cycle of the ancient games. Only about a third of the original survives, split into more than eighty fragments. Modern imaging has revealed tiny inscriptions on its surface, but no contemporary written description of the device has ever been found.
