In 1901, sponge hunters recovered a corroded artifact from an ancient Roman shipwreck off the coast of the Greek island of Andikithira. Recently it was proved to be an astronomical calculator and the truth was very complex belonging to the second century before our era. Some scientists recently examined the Andikithira mechanism, using high-resolution x-ray tomography, and discovered that it consisted of at least thirty bronze gears originally placed in a wooden box.
The incredible artifact could accurately indicate the position of the sun and the moon, besides predicting lunar and solar eclipses, the mechanism of this artifact is technically, according to scientists and experts, the most complex than any instrument known for at least a thousand years after its time.
