Scientists believe they are beginning to unlock the mysteries of an object known as the Antikythera mechanism, which spent over 2000 years at the bottom of the sea. So complex is the device, it is being called the world's oldest computer.
Heavily fortified with calcium and other waste deposits from its former ocean grave, the bronze device is a mesh of cogs, gears, and dials, apparently designed to work together in predicting the positions of our solar system's celestial objects.
Scientists who continue to investigate the object are stunned that something so complex could be made in that era. "The skill with which it was made shows a level of instrument-making not surpassed until the Renaissance," said one scientist.
