After spending the last month at the historic wreck site, the <a href="http://www.whoi.edu/news-release/antikythera-finds" target="_blank">Woods Hole Oceanographic Institute</a> (WHOI) announced that an international team of archaeologists had recovered new items from the Antikythera wreck. Pictured, Greek technical diver Alexandros Sotiriou discovers an intact "lagynos" ceramic table jug and a bronze rigging ring. The new items have indicated the wreck site is much bigger than previously believed, scattered across 300 meters of seafloor.

In 1900, Greek sponge divers inadvertently stumbled upon an incredible ancient shipwreck off the coast of Antikythera. More intriguing were the heavily corroded bronze fragments -- 82 in total, with the largest pictured -- brought to the surface in 1902. The find would stun the world when it was revealed to be a mechanical computer from the 1st century BC.

At first, the Antikythera Mechanism, as it became known, confounded archaeologists who were unsure if it was an astrolabe or an ancient astronomical clock. Today, it is widely believed the mechanism was a complex computer tracking the astronomical calendar and lunar movements, with its manufacture dated to around 100 BC. Radiographic image analysis on the mechanism revealed 30 intricate gear wheels.

A reconstruction of the device now sits at the Archaeological Museum in Athens. Built out of a thin bronze sheet, the mechanism has the first known set of scientific dials and scales. Surrounded by Greek inscriptions, the large upper dial follows the Metonic cycle -- a period of 19 years in which there are 235 lunations. Useful for regulating calendars, there was also a four-year dial for monitoring when the well-loved Panhellenic games -- including the ancient Olympics -- should take place.
