The Grand Grimoire, or the art of controlling celestial, aerial, terrestrial, and infernal spirits. With the TRUE SECRET of speaking with the dead, winning whenever playing the lottery, discovering hidden treasure, etc. Printed from a manuscript of 1522. Multiple editions of it exist, some with material tacked on. It takes the form of a long ritualistic ceremony designed to secure communication with a demon known as "Lucifuge Rofocale" followed by various invocations and incantations and spells. The contents are heretical in the extreme, from rituals involving boiling a black cat to the use of toxic substances in ritual form. Small wonder, that this text has gained so much notoriety. Also included are the "Grimorium Verum", and "The Black Pullet".
