Compare the Medieval World Map, circa 1264, with Ptolemy's

Compare the Medieval World Map, circa 1264, with Ptolemy's 2nd century map, which can be found in the Atlases link in this week's readings, or below in a clearer version. 

In the version below, we have a Renaissance era replica of Ptolemy's map, which had been rediscovered in the late 13th century. Even though Ptolemy's map was more than a thousand years older than the Medieval World Map, it looks much more like maps we would use today. You do not have to answer all of these questions. Simply use them to shape your comparison:

What does Ptolemy's map allow that the medieval map does not? Why was the discovery of Ptolemy's map so important? How did it change the way people saw the universe? From what the two maps emphasize, what appears to be important in Ptolemy's world of 2nd century Greece, as compared to what appears to be important in medieval Europe?
