The Fra Mauro map

I've been grokking out on the so-called "Fra Mauro map," an amazingly detailed (if not particularly accurate, naturally) map of Africa, Asia, and Europe made in the 15th centrury.

I just think its a thing of beauty in itself and bears careful scrutiny.

As Wikipedia puts it:

The Fra Mauro map, "considered the greatest memorial of medieval cartography" according to Roberto Almagia, is a map made around 1450 by the Venetian monk Fra Mauro. It is a circular planisphere drawn on parchment and set in a wooden frame, about two meters in diameter.

You can also access a rather large copy of the map at the following link, for a closer look, and the wikipedia page above has other images as well:
