Ancient Greek hand-powered devices are thought to have been used to predict eclipses and other astronomical events. But only a third of the devices survive, leading researchers to reflect on how they work and what they look like. (Read: 7 Tips to Fix Blue Screen on Windows Computers)
The back of the mechanism had been solved by previous research, but the complex nature of the front gear system remains a mystery.
Scientists from University College London (UCL) believe they ended up solving the puzzle using 3D computer modeling. They have reinvented the entire front panel, and now hope to build a replica Antikythera full scale using modern materials.
On Friday March 12, 2021, a paper published in Scientific Reports revealed a new look at the gear system showing fine detail and intricate parts. The Sun, Moon and planets are featured on an impressive tour de force of ancient Greek brilliance. (Also read: Climate Change, Summer Will Be 6 Months Longer in 2100)
“Our model is the first model that fits all physical evidence and fits the description in the scientific inscription engraved on the mechanism itself,” Professor Tony Freeth was quoted as saying BBC News .
Its mechanism has been described as an astronomical calculator as well computer the world’s first analogue. It was made of bronze and included dozens of gears. The back cover features a description of the cosmos display, which shows the known movements of the five planets at the time the device was built.
But only 82 fragments – which amount to about a third of the device – have survived. This means scientists have to collect complete images using X-Ray data and Ancient Greek mathematical methods.
