Palgrave MacMillan have designed a superb cover for my forthcoming book A History of Exorcism in Catholic Christianity, which is due to be published in April/May 2016 in the Palgrave Historical Studies in Witchcraft and Magic series.
The front cover image is a detail of a thirteenth-century bas relief on a font in Modena Cathedral, showing a bishop aspersing a catechumen before baptism, holding open the book of exorcism. It is a reminder that the modern liturgy of exorcism originated as part of the liturgy of baptism (and, indeed, remains part of it).
