World's Oldest Computer from 60BC Predicted Future

The world's first computer, which is about 2,000 years old, wasn't just used by ancient Greeks to chart the movement of the sun, moon and planets - it was also a fortune telling device, say researchers. The 2,000-year-old astronomical calculator, the Antikythera Mechanism, is a system of intricate bronze gears dating to around 60 BC, used by ancient Greeks to track solar and lunar eclipses. It was retrieved from a shipwreck discovered off the Greek island of Antikythera in 1901, but a decades-long study has only now announced new results. While researchers had previously focused on its internal mechanisms, the study is now attempting to decode minute inscriptions on the remaining fragments of its outer surfaces.


Its ancient engineers may have also given in to a less scientific urge - man's perpetual curiosity about what the future holds. Researchers say the device was probably made on the island of Rhodes and do not think it was unique. It's only unique in the sense that it is the only one ever found. Slight variations in the inscriptions point to at least two people being involved in that, and there could have been more people making its gears. More than a dozen pieces of classical literature, stretched over a period from about 300 BC to 500 AD, make references to devices such as that found at Antikythera. The calculator could add, multiply, divide and subtract. It was also able to align the number of lunar months with years and display where the sun and the moon were in the zodiac.
