Nuremberg Chronicle
Schedel touches briefly on Prester John, locating the legend's beginnings in the Letter of Prester John and, as Brewer (p. 286) suggests, the De Adventu as well. Following earlier Portuguese material related to the myth of Dom Pedro (notably the anonymous Travels of Infante Dom Pedro of Portugal and Santisteban's Book of Dom Pedro), Schedel locates Prester John in Cathay (China).
The text also contains a woodcut of a very European Prester John.
