Without a doubt, Martin Del Rio's in six books is the most complete and exhaustive Encyclopedia of Magic, Necromancy and Witchcraft produced in the late middle ages / early modern period.  This volume covers virtually every aspect from the point of view of the Inquisition - Del Rio was a Jesuit - in hunderds of pages with references in both Greek and Hebrew type.  An amazing treasure trove, unavailable in a modern edition. A must have for anyone interested in the history of the witch trials or the theory and practice of magic - a substantial and beautiful volume.
