Lesser Key of Solomon

Ars Goetia

The most obvious source for the Ars Goetia is Johann Weyer's Pseudomonarchia Daemonum in his De praestigiis daemonum. Weyer does not cite, and is unaware of, any other books in the Lemegeton, indicating that the Lemegeton was derived from his work, not the other way around. The order of the spirits was changed between the two, four additional spirits were added to the later work, and one spirit (Pruflas) was omitted. The omission of Pruflas, a mistake that also occurs in an edition of Pseudomonarchia Daemonum cited in Reginald Scot's The Discoverie of Witchcraft, indicates that the Ars Goetia could not have been compiled before 1570. Indeed, it appears that the Ars Goetia is more dependent upon Scot's translation of Weyer than Weyer's work in itself. Additionally, some material was used from Heinrich Cornelius Agrippa's Three Books of Occult Philosophy, the Heptameron by pseudo-Pietro d'Abano, and the Magical Calendar.

Weyer's Officium Spirituum, which is likely related to a 1583 manuscript titled The Office of Spirits, appears to have ultimately been an elaboration on a 15th-century manuscript titled Le Livre des Esperitz (of which 30 of its 47 spirits are nearly identical to spirits in the Ars Goetia).

In a slightly later copy made by Thomas Rudd, this portion was labelled "Liber Malorum Spirituum seu Goetia", and the seals and demons were paired with those of the 72 angels of the Shemhamphorasch, who were intended to protect the conjurer and control the demons he summoned. The angelic names and seals were derived from a manuscript by Blaise de Vigenère, whose papers were also used by Samuel Liddell MacGregor Mathers in his works for the Hermetic Order of the Golden Dawn. Rudd may have derived his copy of Liber Malorum Spirituum from a now-lost work by Johannes Trithemius, who taught Agrippa, who in turn taught Weyer.

This portion of the work was later translated by S. L. MacGregor Mathers and published by Aleister Crowley under the title The Book of the Goetia of Solomon the King. Crowley added some additional invocations previously unrelated to the original work, as well as essays describing the rituals as psychological exploration instead of demon summoning.

The Seventy-Two Demons

The demons' names (given below) are taken from the Ars Goetia, which differs in terms of number and ranking from the Pseudomonarchia Daemonum of Weyer. As a result of multiple translations, there are multiple spellings for some of the names, which are given in the articles concerning them.

The demons are described as being commanded by four kings of the cardinal directions: Amaymon (East), Corson (West), Ziminiar (North), and Gaap (South). A footnote in one variant edition instead lists them as Oriens or Uriens, Paymon or Paymonia, Ariton or Egyn, and Amaymon or Amaimon, alternatively known as Samael, Azazel, Azael, and Mahazael (purportedly their preferred rabbinic names). Agrippa's Occult Philosophy lists the kings of the cardinal directions as Urieus (East), Amaymon (South), Paymon (West), and Egin (North); again providing the alternate names Samuel (i.e. Samael), Azazel, Azael, and Mahazuel. The Magical Calendar lists them as Bael, Moymon, Poymon, and Egin, though Peterson notes that some variant editions instead list '"Asmodel in the East, Amaymon in the South, Paymon in the West, and Aegym in the North"; "Oriens, Paymon, Egyn, and Amaymon"; or "Amodeo [sic] (king of the East), Paymon (king of the West), Egion (king of the North), and Maimon."'

Ars Theurgia Goetia

The Ars Theurgia Goetia mostly derives from Trithemius's Steganographia, though the seals and order for the spirits are different due to corrupted transmission via manuscript. Rituals not found in Steganographia were added, in some ways conflicting with similar rituals found in the Ars Goetia and Ars Paulina. Most of the spirits summoned are tied to points on a compass, four Emperors tied to the cardinal points (Carnesiel in the East, Amenadiel in the West, Demoriel in the North and Caspiel in the South), sixteen Dukes tied to cardinal points, inter-cardinal points, additional directions between those. There are an additional eleven Wandering Princes, totaling thirty one spirit leaders who each rule several to a few dozen spirits.

Ars Paulina

Derived from book two of Trithemius's Steganographia and from portions of the Heptameron, but purportedly delivered by Paul the Apostle instead of (as claimed by Trithemius) Raziel. Elements from The Magical Calendar, astrological seals by Robert Turner's 1656 translation of Paracelsus's Archidoxes of Magic, and repeated mentions of guns and the year 1641 indicate that this portion was written in the later half of the seventeenth century. Traditions of Paul communicating with heavenly powers are almost as old as Christianity itself, as seen in some interpretations of 2 Corinthians 12:2-4 and the apocryphal Apocalypse of Paul. The Ars Paulina is in turn divided into two books, the first detailing twenty-four angels aligned with the twenty-four hours of the day, the second (derived more from the Heptameron) detailing the 360 spirits of the degrees of the zodiac.

Ars Almadel

Mentioned by Trithemius and Weyer, the latter of whom claimed an Arabic origin for the work. A 15th-century copy is attested to by Robert Turner, and Hebrew copies were discovered in the 20th century. The Ars Almadel instructs the magician on how to create a wax tablet with specific designs intended to contact angels via scrying.

Ars Notoria

The oldest known portion of the Lemegeton, the Ars Notoria (or Notory Art) was first mentioned by Michael Scot in 1236 (and thus was written earlier). The Ars Notoria contains a series of prayers (related to those in The Sworn Book of Honorius) intended to grant eidetic memory and instantaneous learning to the magician. Some copies and editions of the Lemegeton omit this work entirely; A. E. Waite ignores it completely when describing the Lemegeton. It is also known as the Ars Nova.
