The success of Fabio Listrani's Goetia: Tarot in Darkness(9780738770284) has led to the creation of a unique book focusing on the 72 demons of the Ars Goetia. This book showcases essential information from ancient medieval grimoires as well as the unique seals of each demon. Originally the accompanying text to the Goetia: Tarot in Darkness, the book has new sections dedicated to tools and spells for practicing the art of divination, making it an essential manual for researchers and practitioners of the occult.
