The mechanism is the oldest known complex scientific calculator. It contains many gears, and is sometimes called the first known analog computer,[8] although its flawless manufacturing suggests that it may have had a number of predecessors during the Hellenistic Period which have not yet been discovered.[9] It appears to be constructed upon theories of astronomy and mathematics developed by Greek astronomers and it is estimated that it was made around 150-100 BC. One hypothesis is that the device was constructed at an academy founded by the ancient Stoic philosopher Posidonius on the Greek island of Rhodes, which at the time was known as a center of astronomy and mechanical engineering, and that perhaps the astronomer Hipparchus was the engineer who designed it since it contains a lunar mechanism which uses Hipparchus's theory for the motion of the Moon.
Investigators have suggested that the ship could have been carrying it to Rome, together with other treasure looted from the island to support a triumphal parade being staged by Julius Caesar.[10] However, the most recent findings of The Antikythera Mechanism Research Project, as published in the July 30, 2008, edition of Nature also suggest that the concept for the mechanism originated in the colonies of Corinth, which might imply a connection with Archimedes. The circumstances under which it came to be on the cargo ship are unknown. Consensus among scholars is that the mechanism itself was made in the Greek speaking world.[7] All the instructions of the mechanism are written in Greek.
