Over at the Scientific American website, I found these two videos about the decoding of the Antikythera Mechanism.
This amazing piece of technology was discovered at the turn of the last century in a shipwreck in the Greek isles.
An astronomical calendar, Olympic calendar, eclipse calculator and on and on.
As the videos discuss, there is some indication that this device may be a result of the workshop tradition in Syracuse extending from the time of Archimedes.
