This artefact was among wreckage retrieved from a shipwreck off the coast of the Greek island Antikythera in 1901.
The ship was from circa 200 BC.
It must have been built before the shipwreck.
This thing that tracks the planets had 37 cogs. It is the oldest known example of an analogue computer used to predict astronomical positions and eclipses decades in advance.
The first cogs were thought to have been invented hundreds of years later.
So who the hell made this extremely complicated piece of equipment in 200 BC ?
Machines with similar complexity did not appear again until the 14th century in western Europe.
