"Scattered amongst the pages of the Talmud and of the Zohar we find elusive mentions about the Maaseh Kishuf, the Work of Sorcery, and the Maaseh Shedim, the Work of Demons. This grimoire gathers this dispersed knowledge to reconstitute the forbidden craft called in the pages of the Zohar the Serpentine Sorcery, attributed to the wicked Balaam and taught by the King of the Shedim, the demon Ashmedai, also known as Asmodeus. The Talmud tells how the benign shedim conversed with the rabbis who were gifted with the "language of the demons, " instructing them in the knowledge of sorcery; and in the Zohar we find that Asmodeus was Solomon's teacher, and that he gave to him a book of magical knowledge. Uniting academic research with the instructions of his own maggid shed (demonic teacher), Humberto Maggi presents a powerful combination of necromantic experience and scholarly knowledge to create a small jewel in the Solomonic Tradition of Magic.
