Grecian Computer

In the summer of 1901, a mysterious contraption was discovered deep under water in a shipwreck off Point Glyphadia, on the Greek island of Antikythera. Since its discovery, the “Antikythera mechanism” has often been referred to as the world’s first known analogue computer. Using technology that was lost to antiquity until the 14th century, this baffling mechanism was allegedly used to predict astronomical positions and eclipses, as well as the 4-year cycle of the Olympic games.

Inspired by the unparalleled true genius of ancient Grecian astronomers, this puzzle challenges you to turn the dials until all 12 columns add up to 42.
