Late medieval superstition has received a fair amount of attention recently. In 2010, Euan Cameron’s expansive Enchanted Europe: Superstition, Reason, and Religion, 1250–1750 considered it at some length before moving on to later periods, and in 2013 my own Fearful Spirits, Reasoned Follies: The Boundaries of Superstition in Late Medieval Europe dealt with it exclusively. Krzysztof Bracha’s detailed study of a single late medieval author and a major (arguably the major) late medieval treatise on superstition is both the latest and also earliest important study in this area. The book is a German translation and updating of Bracha’s 1999 Polish publication Teolog, diabel i zabobony:Świadectwo traktatu Mikolaja Magni z Jawora De superstitionibus (1405 r.). In the intervening years, he has produced a number of valuable articles on superstition, several in German and a few in English, but it is wonderful to have his major study finally made available in a language that far more Western European and American scholars will be able to read.
