Google has paid tribute to Antikythera mechanism –an ancient Greek analogue computer with a special doodle.

The Antikythera Mechanism, sometimes called the ‘world’s oldest computer’, was discovered in 1901 amongst the wreckage of a Greek ship believed to have sunk sometime between 85 BC and 60 BC, near the island of Antikythera between Crete and Greece.

The mechanism’s complex clocklike assembly of bronze gears and display dials predated other known examples of similar technology by more than 1,000 years.

The archaic looking doodle depicts a stone like wheel predicting the Olympics, lunar and solar eclipse and tracking planetary positions.

The crank-powered device was way ahead of its time – its components are as intricate as those of some 18th-century clocks.

All known fragments of the Antikythera mechanism are kept at the National Archaeological Museum in Athens, along with a number of artistic reconstructions of how the mechanism may have looked.
