The map
The map of Andreas Walsperger is a Latin Mappa Mundi, atypical in its depiction of Africa and in its placing a large castle in China, where others including Fra Mauro's place their grand castle to the north. In Germany, the only other example of the type is the "Mappa mundi Ciziensis" from Zeitz.The parchment measures 57.7 x 75 cm.
