Antikythera Mechanism’s discovery

• On 17th may, 1902, Greek archaeologist Valerios Stais found a corroded chunk of metal which turned out to be part of the world's first computer and became known as the Antikythera Mechanism.

What is the Antikythera Mechanism?

• The Antikythera mechanism is the world's first analogical computer, used by ancient Greeks to chart the movement of the sun, moon and planets, predict lunar and solar eclipses and even signal the next Olympic Games.
• The 2,000-year-old astronomical calculator could also 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.
• The device is an intricate system of more than 30 sophisticated bronze gears housed in a wooden and bronze case the size of a shoebox built around the end of the 2nd Century BC.
• Its mechanical function has seen it hailed as possible the world's oldest-known computer. While the system of gears bears little resemblance to the digital-based computers of the 20th and 21st century, its mechanical design allowed people to make calculations that would have been near impossible on their own.
• This device was probably made on the island of Rhodes. While there was only one device ever found, they do not think it was unique.
• There are minute inscriptions on the remaining fragments of its outer surfaces which point to at least two people being involved in that, and there could have been more people making its gears, according to Mike Edmunds, an astrophysics professor from the University of Cardiff in Wales who has been studying it for over a decade.
• 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 instrument has been variously dated to about 85 BC, but recent studies suggest it may be even older (circa 150 BC).
• The cargo ship inside which it was found is believed to have sunk around 60 BC.
