Video (2min 43sec): 2000-Year-Old Computer Recreated. A working model of an ancient computer was recently recreated in London.

The Antikythera mechanism, is an ancient mechanical calculator (also described as the first known "mechanical computer") designed to calculate astronomical positions. It was discovered in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, in 1901. Subsequent investigation, particularly in 2006, dated it to about 150–100 BC; and hypothesised that it was on board a ship that sank en route from the Greek island of Rhodes to Rome. Technological artifacts of similar complexity did not reappear until a thousand years later.

Jacques-Yves Cousteau visited the wreck for the last time in 1978, but found no more remains of the Antikythera Mechanism. Professor Michael Edmunds of Cardiff University who led the study of the mechanism said: "This device is just extraordinary, the only thing of its kind.

The design is beautiful, the astronomy is exactly right. The way the mechanics are designed just makes your jaw drop. Whoever has done this has done it extremely carefully."

He added: "...in terms of historic and scarcity value, I have to regard this mechanism as being more valuable than the Mona Lisa."
