The Antikythera Mechanism .

Planets , orbits , movements , eclipses , calculations , of the sky done in this 2000 year old mechanism . It was discovered from the Antikythera Roman cargo shipwreck off the Greek island of Antikythera . Incredible , 27 stacked gears seen inside using Radiograph . An 8-ton special x-ray machine was built to penetrate it and view it . Contains 40 hand-cut bronze gears . Unmatched Genius !

The device which shows the ingenuity and the astronomical advancements of the people back then was capable of tracking the movements of Mercury, Venus, Mars, Jupiter and Saturn. Scientists have scanned the world’s oldest computer to find that the Antikythera mechanism even had ‘instructions to use’ on its wooden casing (13 inches x 7 inches x 3.5 inches). It had a single dial which showed the Greek zodiac and Egyptian calendar at the front and two dials at the back that gave information about lunar cycles and eclipses.

The device could predict the Saros cycle as well which is a period of 18 years after which the sun, moon and the earth return to the same relative positions. Now, that is real genius!
