The Ebstorf Map, from the late 13th century

This mappa mundi (a medieval European map of the world) was made by Gervase of Ebstorf in the 1290s, was found in Ebstorf, Germany in 1843. It's made of goatskins (thirty of them!) instead of paper, and measuring 12 ft x 12 ft (3.6 x 3.6 m). Unfortunately it was destroyed during the bombing of Hannover in 1943, but there are some surviving black and white photographs and color facsimiles.
