In 1901, sponge divers found an extraordinary mechanism on the sea bottom near the island of Antikythera. It astonished the whole international community, stumping scientists for decades. Was it an astrolabe, an astronomical clock, or something else? More recent research is revealing its secrets. Dating from around the 1st century B.C., it is the most sophisticated mechanism known from the ancient world. The Antikythera Mechanism operated as a complex mechanical "computer" to track the cycles of the Solar System.
