Heresy and inquisition in France, 1200-1300 is an invaluable collection of primary sources in translation, aimed at students and academics alike. It provides a wide array of materials on both heresy (Cathars and Waldensians) and the persecution of heresy in medieval France. The book is divided into eight sections, each devoted to a different genre of source material. It contains substantial material pertaining to the setting up and practice of inquisitions into heretical wickedness, and a large number of translations from the registers of inquisition trials. Each source is introduced fully and is accompanied by references to useful modern commentaries. The study of heresy and inquisition has always aroused considerable scholarly debate; with this book, students and scholars can form their own interpretations of the key issues, from the texts written in the period itself.
