This classic in the study of medieval history provides parallel source translations, so arranged and equipped with descriptive information that effective training can be given in the use of source material.

Duncalf and Krey provide five events with source problems to be considered: the coronation of Charles the Great, Canossa, the capture of Jerusalem in 1099, the departure of the University from Paris, and the coronation of Cola Di Rienzo. The intent is that students would be able to work inductively, obtaining elementary training in the fundamentals of historical method, while at the same time becoming familiar with basic medieval source material.
