The year of 1901 by Antikythera, a Greek island, a shipwreck was found with many interesting artifacts, like money, works of art and crafts etc. However, the item that made the archaeologist Valerios Stais (and later many others) most curious and confused was a lump of bronze and wood where he discovered a gear within it. What was it then that was found at the bottom of the Ionian Sea? The item that later has been dated to 200 BC and has been termed first known analogue computer. It was a machine that could indicate how the sky would look like decades to come, from the position of the sun and the moon. Cardiff University professor Michael Edmunds, who led a 2006 study of the mechanism, described the device as “just extraordinary, the only thing of its kind”, and said that its astronomy was “exactly right”. However, many Ancient writers included Cicero indicated that these devices existed, but the Antikythera computer is the only one that has been found so far. See the story about the device and how it worked below.
