It fell to the seabed after the ship that carried it was destroyed about 2,200 years ago. It was one of the great wonders of the ancient world. And we had no idea what it was, until 50 years after the diver was reopened in 1901.
This is a freakishly sophisticated machine.
It is a bronze brush and lever mechanism used to predict the solar and moon phases.
It can be even more complicated – it is also able to calculate the progress of a planet and a star through the night sky.
So it was a "divination machine".
A hand-screwed calculator used by priests, prophets, and propellers to exhilarate the audience with precise predictions about the upcoming lashes – and the looming celestial coordinates.
So … just how powerful was it?
An analog computer is fascinated by the generation of computer entrepreneurs. So a series of expeditions to finance a small Antikythera island between Greece and Crete to see if more mysterious pieces of the device could be recovered.
Last year, one exciting piece was found on the seafloor's expedition.
A thick, inlaid bronze disc, approximately 8 cm wide.
Now there is a new article in the Israeli publication Haaretz has sent an unexpected tremor around the world.
It announced that it was a wrestler out of the Anikythera mechanism itself. And, as it carried the sign of the bull – Taurus – this proves the machine was much more complicated than the many daring dream.
But … not so fast.
Since 2012, the waterfalls from Antikythera are back to earn steep cliffs to get more treasure.
In the 1970s, researchers Jean-Jacques Kusteo seriously spoiled the wreck when he cut off many marble and bronze sculptures from the bottom of the sea. What's left has been scattered or deeply scattered.
However, the bronze disc seems promising. It had four crests, with large cog teeth at regular intervals.
Since then, it has been X-rays and scanned.
It has been found to be engraved with a bull's image. Is it Taurus, a star constellation and a zodiac sign?
Engineers and mathematicians have struggled to understand the complexity of the Antikythera mechanism, since in the 1950s it was understood that it was a metal machine rather than an inlaid stone.
Many have tried to reconstruct a set of teeth, wheels and levers.
As you know, it was built in Greek and used Babylonian calendar and star observations to calculate the sun and moon movements to predict eclipses and equinoxes.
There are also striking suggestions that can be traced to planetary and constellation movements.
If that were true, it would be incredible. Such a wider combination of astronomical research, mathematics and mechanical translation has not yet reached 500 years yet.
The new disc, if it belongs to the device, could confirm its ability to predict the positions of star groups that are so important to priests and viewers of the time.
But it's not true.
Archaeologists quickly stressed that the new report too emphasized the importance of the bronze disc.
But a huge picture of everything related to the mysterious old device looked at an article that spreads quickly and widely … even to experts who should know better.
What really was the new drive is unknown.
But the bull-engraved plate is very unlikely to be part of the complex operation of the device. If the four crests were crosses, they are unusually unprocessed for such a complex device. Most likely, they were practical accessories for a disk to decorate.
At best, the bull's disk could be a decorative piece attached to the Antikythera mechanism body. But it's just as likely that it has adorned some ancient wood panel or even priestly cloths.
At the same time, hunting of several machines continues.
How many teeth make up the original device is unknown.
But conclusions based on the positions and fittings attached to the details that have already been found are from 37 to 70 points.
Others claim that the ship may actually have two different devices, the components of which are mixed.
In any case, the precision of the production mechanism required to operate such a mechanism is enormous: because of a small buckle, only one cog could throw out or stuck its calculations.
