All new 2023 edition. Grimorium Verum is one of the most notorious handbooks of black magic -- one of the few that deals openly with spirits of darkness. People have long sought the aid of non-physical beings; the biblical king Solomon in particular had a reputation since ancient times for commanding demons. There are many texts purporting to reveal Solomon's methods, but most are extremely complicated and difficult. Grimorium Verum is one of the easier texts, but also one of the most sinister. It includes a catalog of specific demons and how to draw on their powers. This second edition has been extensively updated, reflecting 15 years of additional research, including material from newly identified manuscript and printed sources, complete French text, and 7 appendices.
