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 ÀœAntikythera mechanismÀ 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. Difficulty: 5/5
