The Antikythera Computer describes a 2000(+) year-old device discovered in the remains of a Greek shipwreck that looks to have operated through a technically advanced (relative to the time it was created) interaction of gears and levers. It is theorized the machine was used as a calendar device. It is described by some as an early version of a computer, in that it's gears were used and manipulated to help compute specific calendar functions and lunar / solar positions.
