Power & Purity: Cathar Heresy in Medieval Italy
"Carol Lansing's book is a fine example of a local study that transcends its original scope by stimulating further reflection on the nature and function of heresy, and by implication on that of religion....A particular mention deserves Lansing's skilful reading of religious and political symbolism, which unveils the probable implications of a piece of rotten meat thrown at a procession a long time ago."--Sixteenth Century Journal
