The famous Hereford world map, the ' Mappa Mundi', dates from around 1300, & was painted on one skin of calf-parchment, less than 1 mm thick & measuring about 130 cm square. When we read of its frequent ordeals, we may marvel that it is still in good condition & can be examined. Yet, it is by no means the oldest surviving mappamundi, nor was it the largest: the Ebstorf map (destroyed by bombing in 1943) was of similar age & almost three times bigger. Mappaemundi may be square or round, large or small, extremely simple or amazingly complex. Their geography is unfamiliar & many of their fauna are grotesque. Their importance is enormous: for their encyclopaedic ambition, for their place in devotional & romanesque iconography & for their attempts to document contemporary world views. In setting the Hereford world map in context, P.D.A. Harvey & his twenty-four collaborators introduce us to medieval ideas of the world & man's place in it in ways that will excite historians, geographers, students of art history, theologians, & anyone interested in the medieval world view.
