On 17 May 1902, archaeologist Valerios Stais made the most celebrated find while studying the artefacts at the National Archaeological Museum. He noticed that a severely corroded piece of bronze had a gear wheel embedded in it and legible inscriptions in Greek. The object would come to be known as the Antikythera mechanism. Originally thought to be one of the first forms of a mechanised clock or an astrolabe, it is at times referred to as the world’s oldest known analog computer.
