The Antikythera Mechanism

The Antikythera Mechanism is a mysterious computer that was made about the time of Christ. Nobody knows who made it or what civilization made it. It was inscribed with Greek so maybe it was the Greeks who made it. This makes me wonder what else is out there that we don't know about. It is quite an astonishing bit of technology not repeated for 1400 years. Does anybody know of anything else like this ?




This is a very puzzling machine indeed. More information can be found here.
