Computer from 65 BC

Scientists finally discern the hidden mechanics of a 65 BC computer device recovered from a wrecked Roman ship. It was accidentally discovered by Elias Stadiatos in 1900 and has since been a source of mystery. Since its discovery, scientists have been trying to reconstruct the device, which is now known to be an astronomical calendar capable of tracking with remarkable precision the position of the sun, several heavenly bodies and the phases of the moon. Experts believe it to be the earliest-known device to use gear wheels and by far the most sophisticated object to be found from the ancient and medieval periods.
