Background information

The Antikythera mechanism is generally referred to as the first known analogue computer and discovered in 1902 in a Roman shipwreck of the coast of Antikythera, Greece. It was constructed by Greek scientists in the 1^st or 2^nd century BC based on theories of astronomy and mathematics of that time. Studies have revealed that it must have had 37 meshing bronze gears (or possibly more) in a wooden frame. These gears were able to track the movements of the Moon and the Sun through the zodiac. It was able to predict astronomical positions and eclipses many years in advance. There must have been highly detailed panels with dates, eclipses, calendars and more at the front and the back which are, except for some small pieces, lost. One thing is sure, it’s an amazing analogue computer over two centuries old.
