Ancient Advanced Technology
Found in a shipwreck over a century ago, an enigmatic bronze clock-like machine consisting of more than 30 hand-cut bronze gears that were used to predict the positions of the sun, moon and planets at any chosen time.
The Ancient Greek astronomical calculator dated to around 200 B.C. was called the Antikythera Mechanism after the tiny island near to where the treasure ship was discovered.
Roman lawyer, orator and politician Cicero (106–43 B.C.E.) described a machine made by mathematician and inventor Archimedes (circa 287–212 B.C.E.) “on which were delineated the motions of the sun and moon and of those five stars which are called wanderers ... (the five planets) ...”
Cicero’s machine sounds just like the Antikythera mechanism.
