The Antikythera mechanism is an ancient mechanical computer designed to calculate astronomical positions. It was recovered in 1900–1901 from the Antikythera wreck. However, its significance and complexity were not understood until decades later. The construction has been dated to the early 1st century BCE. Technological artifacts of similar complexity and workmanship did not reappear until the 14th century, when mechanical astronomical clocks were built in Europe. modern reconstruction at…

How do we know what people in earlier times knew? The Antikythera mechanism is an ancient mechanical computer designed to calculate astronomical positions. It is thouight to have been constructed in the or century BCE.
