                                    A Reconstruction of the Antikythera Mechanism





Dated to ca 80 BC

In the year 1900 the bronze remains of a mechanical device were retrieved from a shipwreck off Antikythera, near Crete.

It was not clear initially what the device was, except that it was clearly a sophisticated mechanism. X-ray analysis was subsequently used to probe the inner structure of the device, the details of the gears. Finally in 1974, a full analysis was published by Professor D. De Solla Price. While some of the original gearing was missing, there was enough to work out that the device was intended to show the motion of the Moon, Sun, and most likely the Planets through the years, when the handle was turned. A few years ago, John Gleave, an orrery maker based in the United Kingdom, decided to construct a working replica of the original mechanism.
