Found beneath the floor of an English cathedral, a large calfskin canvas featuring what appeared to be a map of the world. Once recovered and repaired, the map was found to date to 1285. Cities and towns are depicted on the medieval Mappa Mundi, more than 500 ink drawings illustrate biblical events, exotic plants and animals, wild and strange creatures from legends, and dipictions from classical myths. The remarkable artifact remains the largest medieval map still known to exist.
The largest known late medieval world map was the "Ebstorf Mappa Mundi". This map named for the Benedictine monastery in Ebstorf Germany where it was found in 1830. The map was most likely produced in the middle of the thirteenth century. Unfortunately the map was completely destroyed during the Second World War.
