It's believed the destroyed vessel discovered near the Greek island of Antikythera sank between 70 B.C. and 60 B.C. on its way from Asia Minor west to Rome. It has been a source of fascination for undersea explorers and archaeologists since first being discovered by sponge divers in 1900.
But recently, excavators and divers have discovered that the wreck site is much larger than had previously been reported, and could still contain untold treasures from the Ancient World.
Because of the fantastic depth of the shipwreck - 180 feet below sea level - divers must wear a specialized exo-suit, seen above, to explore the wreck site. It allows divers to remain underwater, safely breathing oxygen, for up to 3 hours.
The "Return to Antikythera" project, as it's been named Woods Hole Oceanographic Institute and the Hellenic Ministry of Culture and Sports, hopes to retrieve as much of the ship's cargo as is salvageable. So far, discoveries have included an intact table jug, four giant marble horses, a piece of what was once an ornate bed frame and a 2-meter-long bronze spear.
