The Hereford Mappa Mundi is the largest medieval map still known to exist, depicting the known world. It is a religious rather than literal depiction, featuring heaven, hell and the path to salvation. Dating from c. 1300 AD, the map is drawn in a form deriving from the T and O pattern. It is displayed at Hereford Cathedral in Hereford, England. The map was created as an intricate work of art rather than as a navigational tool. Sources for the information presented on the map include the Alexander tradition, medieval bestiaries and legends of monstrous races, as well as the Bible.
