In 1900 a sponge diver called Elias Stadiatos discovered the wreck of an ancient merchant ship off the tiny island of Antikythera near Crete. The corbita, dating from the first century B.C., was heavily laden with treasure of all kinds, original bronze life-size statues, marble reproductions of older works, jewelry, wine, fine furniture and one immensely complicated scientific instrument. The Antikythera mechanism was originally housed in a wooden box about the size of a shoebox with dials on the outside and a complex clockwork assembly of gears inscribed and configured to produce solar and lunar positions in synchronization with the calendar year. By rotating a handle on its side, its owner could read on its front and back dials the progressions of the lunar and synodic months over four-year cycles. The device has been estimated to be accurate to 1 part in 40,000. (more inside...)
