In the year 1900 a team of sea sponge divers stumbled upon a shipwreck from the late Hellenistic Era. Among the statues, coins, and jewellery, the salvage crew pulled out a small box covered in moss. Initially ignored, the contents of this box proved to be the most sophisticated mechanical device that survives from the ancient world. The Antikythera mechanism computed all the known motions of the heavens and its complexity was described by one scholar as "like finding a jet engine in King Tut's tomb."
