Archaeologists found a missing part of the 2,200-year-old Antikythera Mechanism


The missing part of the world's oldest analog computer, Antikythera Mechanism, is believed to have been found on the Aegean sea floor.

Found in 2017 resembling greenish stone, further investigations on land have revealed it as an eight centimeter bronze disc. It features four metal arms at each corner with holes for pins, an x-ray revealing carvings of a Taurus bull.

Although it cannot be said conclusively whether it is the missing part of the Mechanism, based on the evidence found so far, it is said to look exactly like other parts of the computer.

Another possibility is that it can be part of a second mechanism that has not been explored, or something else at all.

What is known so far is that Antikythera Mechanism was built by ancient Greeks to calculate different astronomical positions.

It first disappeared 2,200 years ago after the ship that took it sank near the Antikythera island. It was first rediscovered in 1901 by sponge divers, who brought the discovery of drawing them back ashore, where it was investigated by archaeologist Valerios Stais at the National Archaeological Museum in Athens.

Since then scientists have discovered that computers can perform basic mathematical functions and can accurately track the movements of the sun, moon, planets and constellations, along with the time of the equinox and eclipse.

The site of this invention has been thoroughly explored and looted. Among the findings were statues made of bronze and marble, coins, sarcophagus covers, and furniture.

In addition to the importance of the Mechanism itself, Sarah Bond, a related professor of Classics at the University of Iowa, said her findings were very important when it came to the field of archeology as a whole.

"The Antikythera Mechanism is an important object in the history of ancient technology, but it is also a prism to trace the development of archeology as a professional field," he said.

"This reveals sophisticated astrological instruments made and used by ancient engineers, but the protracted nature of bottom excavations reveals archeological progress in scanning, 3D modeling, and many other sophisticated approaches in reconstructing and analyzing computers."

Examination on bronze disks continues.
