"Berlin Researchers Crack the Ptolemy Code"

This news is about a year old but I've just discovered it for myself and thought I would share it with others.  Apparently, a research group has managed to make some sense of the long-frustrating maps of Ptolemy and, in doing so, have added about 1,000 years of history to many Germanic population centers.  Just a little something to think about before giving players handout maps; they don't need to be perfectly accurate.  Maybe you don't want them to take 2,000 years to decode them, but they can be a little off.  Read more about it here!
