If you have any interest in ancient science and technology, you have almost certainly heard of the Antikythera mechanism, an ancient Greek mechanical orrery that was discovered in 1901 in an ancient shipwreck off the coast of the Greek island of Antikythera. It is a clockwork mechanism that was used to keep track of Olympiads and the movements of the celestial bodies. The wreck the device was recovered from dates to between c. 70 and c. 60 BC. The Antikythera mechanism itself was most likely originally created sometime in around the late second or early first century BC.
In popular science writings and in popular culture, the Antikythera mechanism is usually described as an “ancient Greek computer.” It is usually presented as an astonishing example of how incredibly advanced ancient Greek technology was and it is usually presented in such a way that makes it sound as though we had no idea that devices like it even existed before it was discovered.
The truth, though, is that devices like the Antikythera mechanism are actually well-attested in surviving ancient written sources and classical scholars already knew that these kinds of devices existed in antiquity long before the Antikythera mechanism was discovered. The Antikythera mechanism is not significant because it is the only device of its kind that ever existed, but rather because it is the only one of its kind that is known to have survived to the present day.
