In 1900, sponge divers off the coast of the tiny Greek island of Antikythera made an astonishing discovery: the wreck of an ancient Roman ship lay 200 feet beneath the water, its dazzling cargo spread out over the ocean floor. Among the life-size statues and amphorae was an encrusted piece of metal, which after nearly a century of investigation, is finally revealing its secrets.

Called the Antikythera Mechanism, study has shown that this improbably preserved object is actually an ancient Greek astronomical computer of a technical sophistication not seen until the clock making traditions of Medieval Europe—1,500 years after the Mechanism is believed to have been made (about 200 BC).Recent advances in computer imaging as well as painstaking scholarship have finally elucidated nearly all details of the Mechanism.
