The Antikythera wreck
The Antikythera wreck is a Roman-era shipwreck dating from the 2nd quarter of the 1st century BC. It was discovered by sponge divers off Point Glyphadia on the Greek island of Antikythera in 1900.
The wreck yielded numerous statues, coins and other artifacts dating back to the 4th century BC, as well as the severely corroded remnants of a device many regard as the world's oldest known analog computer, the Antikythera mechanism. These ancient artifacts, works of art, and elements of the ship itself are now displayed at the National Archaeological Museum of Athens.
