Whether it be the Antikythera mechanism, the world’s oldest computer, or Roman Dodecahedra, an ancient candle holder from the 2nd or 3rd centuries CE, these are fascinating artifacts and gadgets from ancient times that you probably never knew existed. Continue reading for more.

The Antikythera mechanism (above video) is basically an ancient analog computer designed to calculate astronomical positions. It was recovered in 1900-1901 from the Antikythera wreck, but its significance and complexity were not understood until a century later.

Jacques Cousteau visited the wreck in 1978 but, although he found new dating evidence, he did not find any additional remains of the Antikythera mechanism. The construction has been dated to the early 1st century BCE. Technological artifacts approaching its complexity and workmanship did not appear again until the 14th century CE, when mechanical astronomical clocks began to be built in Western Europe.
