Ars Salomonis is a practical manual for working with the talismanic figures found in the Key of Solomon, the most significant of all grimoires. The Key of Solomon has a unique place in the history of magic, having heavily influenced the development of various traditions including ceremonial magic and Wicca. English alchemist and sorceror Gary St Michael Nottingham includes the planetary pentacles and sigils of the associated planetary spirits for the first time, both vital to their successful use in sorcery. The author describes two methods for empowering and activating the planetary pentacles: first a simple practice using the Kabbalistic Middle Pillar exercise, followed by a more traditional and complex form involving the conjuration of the spirits into a crystal shewstone. In so doing he makes this vital work safely accessible to beginners as an ideal entranceway into the grimoire tradition. Including a full description of all necessary and appropriate preparations, the Lesser Banishing Ritual of the Pentagram, the Middle Pillar, altar construction and the consecration, use and deactivation of the pentacles, this work provides a practical guide to the talismanic magic of the Key of Solomon suitable for all levels of practitioners. Ars Salomonis is Vol. II of the 7-.volume Foundations of Practical Sorcery series by Gary St Michael Nottingham.
