The Hereford Mappa Mundi is the oldest most famous world map known to exist. It was made by a group of craftsmen sometime between 1280 AD and 1300 AD on a single calf skin. Jerusalem is at the center of the map and there are several tiny images of Christian significance on the map. It has deep ties to the Hereford Cathedral in England where it is on display. This image has been upsized to make larger prints available.
