Without a doubt, Martin Del Rio's Disquisitionum magicarum  (Inquest into Magic) 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 hundreds of pages with references in both Greek and Hebrew type.  An amazing occult treasure trove and the text that would supplant the hideous Malleus Maleficarum as THE handbook of the witchhunts. 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. Martin Del Rio Disquistionum Magicarum libri Sex. Lugduni Apud 1604 in Folio.  Fourth Edition with signatures.  Bound in Modern half-leather with gilt spine. Clean and well-bound with minimal foxing or staining.  An exemplary and substantial edition.
