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. Frederic Duncalf (1882-1963) taught at Bowdoin College in 1910-1911 and at The University of Texas at Austin from 1911 to 1913. After a brief tenure at the University of Illinois in 1913-14, he joined the permanent faculty of the University of Texas in 1914. Professor Duncalf was the coauthor of several books, including 'Old Europe and Our Nations' and 'Ancient and Medieval History: The Rise of Classical Culture and the Development of Medieval Civilization'. August C. Krey (1887-1961) was Professor of History at the University of Minnesota. His other publications include 'History and the Social Web'.
