There is a superb article in Popular Mechanics about the discovery & ongoing deciphering of the Antikythera machine. I think it's worth a full read.

This is the story—or at least one of the stories—of how one of the world’s most confounding archaeological objects, the Antikythera mechanism, began its 2,000-year-long residency at the bottom of the Aegean. Pinpointing the mechanism’s origins
Milled with millimeter precision, likely using ancient tools like vertical lathes and bow drills, the device contained dozens of gear wheels that operated together in a dizzying display of astronomical information.
With insights gleaned from the fragments that remain, scientists know that a hand-cranked dial on its front side tracked the motion of the sun, the moon, and the other five planets known to antiquity: Mercury, Venus, Mars, Jupiter, and Saturn. The other side of the device housed two more circular dials. The upper dial reconciled the mismatch in periods between the lunar month and solar year, while the lower dial calculated both lunar and solar eclipses. It even contained a separate, smaller dial for marking athletic events like the Olympic Games.
