I remember reading about the Antikythera mechanism in a “Ripley’s Believe It Or Not” back when I was a kid in the 50’s.
There was a program on one of the science channels a year or so back about the mechanism which they pretty much understand now. It was even more complex than originally thought.
I believe some guy has even made a working copy of it.
Yep that is a picture of it. I just watched something about it last night on the History channel. It is horrible that the library of Alexandria was lost.
