Right now, though, I'm having fun looking at medieval maps of the world. My favorite so far, a mappa mundi placing Jerusalem at the center of the universe, with the three surrounding continents stretching off like the petals of a trillium.* Not that Europe has ever really been anything but a continent by courtesy: let's be honest here, it's a glorified peninsula.
On the other hand, this guy rocks my socks.
* Yeah, bet that was useful for getting around with.
