Truley, one of the wonders of the ancient times and of course one of the artifacts found with the bronze items off of the coast of AntiKythera in the early 1900's by sponge divers.
This ancient wonder is thought to have been designed and built by Archimedes to calculate time, day, month, years, etc.
It has been x-rayed and studied by many mathematicians and scientists and engineers and it contains very accurately cut gears and shafts, that work together to calculate the elements of time. Still many things are a mystery about this and hopefully ,some day the whole idea of its purpose will come to light.
