This title, first published in 1969, is concerned with historic documents and their uses, and with a discussion of living standards among the peasants, as it is the author’s belief that any worthwhile discussion is impossible without an understanding of the sources and their limitations. With its emphasis on the controversial and debateable, this book is admirable proof that a study of medieval history is not merely a matter of memorising facts.
