The Antikythera Mechanism Mystery Finally Solved?

A 2,000-year-old device often referred to as the world’s oldest “computer” has been recreated by scientists trying to understand how it worked. The Antikythera Mechanism has baffled experts since it was found on a Roman-era shipwreck in Greece in 1901.
The hand-powered Ancient Greek device is thought to have been used to predict eclipses and other astronomical events.
But only a third of the device survived, leaving researchers pondering how it worked and what it looked like.
The back of the mechanism was solved by earlier studies, but the nature of its complex gearing system at the front has remained a mystery.
Scientists from University College London (UCL) believe they have finally cracked the puzzle using 3D computer modelling. They have recreated the entire front panel, and now hope to build a full-scale replica of the Antikythera using modern materials.
On Friday, a paper published in Scientific Reports revealed a new display of the gearing system that showed its fine details and complex parts.
“The Sun, Moon and planets are displayed in an impressive tour de force of ancient Greek brilliance,” the paper’s lead author, Professor Tony Freeth, said.
“Ours is the first model that conforms to all the physical evidence and matches the descriptions in the scientific inscriptions engraved on the mechanism itself,” he added.
The mechanism has been described as an astronomical calculator as well as the world’s first analogue computer. It is made of bronze and includes dozens of gears.
The back cover features a description of the cosmos display, which shows the motion of the five planets that were known at the time the device was built.
But only 82 fragments – amounting to around a third of the device – survived, This meant scientists have had to piece together the full picture using X-Ray data and an Ancient Greek mathematical method.

I’m sure it’s a portal machine to take your wealth with you to the afterlife.

Are we serious? Does one assume that there was a limited knowledge of stars and planets in the age of the building of the Antikythera machine. Why?
The books, that our current civilizations evolution are based upon, carry forward the written records of what astronomy was and to a degree, so many scholars cannot comprehend how the past members of ancient societies could have known, with out the aid of sophisticated computers and modern instruments.
Who says the creators did not know of all the planets? What if this was merely a limited use machine created for a specific purpose?
A gift perhaps, that ended up in a different time, none the less a gift?!

It could be for any number of purposes, we really don’t know. It could have been one of many, or it might be unique. It appears to be able to predict things like eclipses, but with so much of it missing, all we can do is speculate.
