His octagonal structure featured a wind vane and a complex sundial on each of its faces. Before its discovery we had no idea the Greeks had technology anywhere near this sophisticated. Wright also took his own photographs of the fragments and performed radiography with a device he created to adapt X-ray equipment for this purpose.
The parts that work these planetary pointers are gone, but text on the front plate of the mechanism confirms, according to Jones and his teamthat the planetary motion was modeled mathematically using numerous complex gears—and that it was highly accurate.
In creating his reconstruction, Wright attempted to stay as true to the original as the radiographs would prove. Among the ship timbers and bronze figures, Cousteau and his team found bronze and silver coins from the Asia Minor colonies of Pergamon and Ephesus, which are now part of Turkey.
There was a good picture for the bottom halfbut the rest had to be cobbled together from several different places. All of the artifacts went to the National Archaeological Museum in Athens. Pointers track the position of the 5 planets known to the Greeks, the sun, and the moon, all as observed from Earth.
After the fall of the ancient Greek civilization, it is believed that the kind of craftsmanship and technology the mechanism represents moved east through the Byzantine Empire and on to the Arabs after the fall of Constantinople.
Venus, Mercury, Mars, Jupiter, and Saturn. This particular gear was crucial to reconciling the month solar year with the The mechanism was housed in a wooden box and controlled with a knob on one side. The other acts as an eclipse predictor, operating on the month Saros cycle to show the dates of both solar and lunar eclipses.
That year, Mike Edmunds of Cardiff University in Wales and his team published CT scans of the fragments, revealing more details of the inner workings, as well as hidden inscriptions—and triggering a burst of scholarly research. In his writing, Cicero wrote of some novel differences between this new planetarium and an earlier astronomical device he greatly admired, the sphere of Archimedes.
Who Made the Antikythera Mechanism? If the Antikythera mechanism had been the work of Archimedes, Price believes that his name would certainly have been attached to it in historical records, followed closely by a great deal of praise for having invented the differential gear.
Because of the different speeds of these orbits, some of the planets experience apparent retrograde motionand capturing this epicycle motion is the reason for much of the complex gearing system. It also computes the seventy six-year Callippic cycle, which is four times the length of the Metonic cycle and was proposed by Greek astronomer Callippus around BC as an improvement over the Metonic cycle.
The month inscriptions on the fragments pointed to Corinth, or a colony of Corinth such as Syracuse on the island of Sicily. These internal gearing systems output their calculations on the back of the device through two spiral grooves.
The Antikythera mechanism, which was designed to calculate dates and predict astronomical phenomena, has therefore been called the earliest analog computer. They were able to confirm once and for all that the largest gear definitely had teeth. This design made it possible to reset the output by lifting the pointer as one would lift the arm of a record player.
At the time of the shipwreck, each of the Greek states used its own calendar scheme. The mechanism includes hands or pointers for Mercury, Venus, Mars, Jupiter, and Saturn, all of which are easily visible in the sky, as well as a rotating ball that showed the phases of the Moon.
Two subsystems emerge from this train, one based on the Sun and one on the Moon. You can see this in the video pretty clearly. He began his study of the fragments in the s, using still photographs and radiographs to make sense of the gear ratios.
The calendar is based on the time from one full moon to the next, and a special dial allowed the user to also envision the seasons, which would have been useful for agriculture. He nevertheless took the task on, working with artist Beverly Pope to create the intricate line drawings you see reprinted here.
It also tracked the seasons and ancient festivals like the Olympics. This means that either the Roman ship was vastly larger than previously thought or there is a separate wreck down there. Inscriptions explained which stars rose and set on any particular date.
Diagrams Reprinted by Permission Gears from the Greeks:Decoding the Antikythera Mechanism, the First Computer Crammed inside, obscured by corrosion, are traces of technology that appear The Antikythera mechanism was similar in size to a mantel. It was considered to be the first mechanism with gears in human history.

Archeologists dubbed the instrument the Antikythera mechanism. The genius — and mystery — of this piece of ancient Greek technology, arguably the world’s first computer, is why Google is. The Most Mysterious Object in the History of Technology Multispectral scanning reveals ancient text on the fabled Antikythera Mechanism, and suggests the machine was a mechanical textbook.
