About the Book Also called the Black Books. It is a compiling of Black Magic grimoires from the British Library, detailing the Black Mass, Devil evocation, spirit summoning and a lot more. This grimoire details actual rituals as they were performed hundreds of years ago. This is only for those interested in Black Magick. Translated by master ooccultist, with 40 years of practice behind him, Robert Blanchard. The greatest occult translator in modern times. You can depend on his translations to be the best. This book is hard to find used and if you do, it will cost well over $300 dollars. That is how excellent IGOS texts are.
