A 2100 year old bronze and iron computer that predicted eclipses and other astronomical events also showed the cycle of the Greek Olympics and the related games that led up to it, researchers reported recently
The research team also has been able to decipher all the month names from the heavily corroded fragments of the so called Antikythera mechanism, providing the first concrete evidence that an astronomical scheme devised by the Greek astronomer Geminos was put to practical use.
The Antikythera mechanism is thought to have been made around 100 BC. In 2006, researchers examined it with a massive Xray tomography machine similar to that used to perform CT scans on humans and concluded that the device originally contained 37 gears that formed an astronomical computer. Using a hand crank, one could determine the positions of heavenly objects on a given day.
