The 2,000-Year-Old Computer Used By Ancient Greeks

In 1901, divers looking for sponges in the Antikythera area between Crete and Greece came upon one of the most mysterious discoveries the world has ever seen - the Antikythera Mechanism. The device was being carried on a Roman ship that was wrecked between 80 and 60 B.C.

After the device was found, it wasn't until 50 years later that an Australian archaeologist using X-rays began to discover that there was a lot more to the mystery piece than was originally thought. However, the actual function of the Antikythera Mechanism wasn't known until decades later.
