The Ars Goetia refers to the first section of King Solomon's grimoire, and contains descriptions of the seventy-two demons that Solomon is said to have evoked and confined in a bronze vessel sealed by magic symbols, and that he obliged to work for him. It gives instructions on constructing a similar bronze vessel, and using the proper magic formulae to safely call up those demons. The operation given is complex, and includes much detail. The Ars Goetia differs from other goetic texts[citation needed] in that the entities summoned are to be compelled into obedience, rather than asked for favors.
It deals with the evocation of all classes of spirits, evil, indifferent and good; its opening Rites are those of Paimon, Orias, Astaroth and the whole cohort of Infernus. The second part, or Theurgia Goëtia, deals with the spirits of the cardinal points and their inferiors. These are mixed natures, some good and some evil.[1]
The Ars Goetia assigns a rank and a title of nobility to each member of the infernal hierarchy, and gives the demons' 'signs they have to pay allegiance to', or seals. The lists of entities in the Ars Goetia correspond (to high but varying degree, often according to edition) with those in the Steganographia of Trithemius, circa 1500, and Johann Weyer's Pseudomonarchia Daemonum an appendix appearing in later editions of his De Praestigiis Daemonum, of 1563.
A revised English edition of the Ars Goetia was published in 1904 by magician Aleister Crowley, and it serves as a key component of his popular and highly influential system of magick. It has since become a relatively well-known book of magic (arguably, the most popular of the grimoires) and has even been featured in places like the graphic novel Promethea by Alan Moore or James Blish's novel Black Easter.
