The Goetia: History and Content

The Goetia is the first and most widely known book of the Lemegeton Clavicula Salomonis, the Lesser Key of Solomon, a compilation of ceremonial magic texts assembled in seventeenth-century England. It catalogues seventy-two demonic or infernal spirits, presenting each with a description of appearance, rank, title, seal, and area of competence, along with instructions for evoking the spirits using a ritual circle, a triangle of manifestation, specific prayers and divine names, and the spirit’s individual seal. The Goetia has exerted a defining influence on Western demonology and ceremonial magick from the seventeenth century to the present.

The word “goetia” derives from the Greek word for howling or mourning and came to denote low or demonic magic in Hellenistic terminology, distinguished from theourgia (high or divine magic). In later usage, the term attached specifically to the practice of evoking spirits from the list, and the text itself took the name.

History and origins

The text’s immediate literary ancestor is the Pseudomonarchia Daemonum (False Kingdom of Demons), a catalogue of sixty-nine spirits published by the German physician Johann Weyer in 1577 as an appendix to his skeptical demonological treatise De Praestigiis Daemonum. Weyer, himself a critic of witch persecution who believed those accused of witchcraft were mentally ill rather than truly malefic, ironically preserved an important body of spirit lore in the very work that questioned its reality.

The Goetia expanded Weyer’s list to seventy-two spirits, a number with symbolic significance (seventy-two is the traditional number of nations of the world in rabbinical literature, and seventy-two angels derive the name of God from Exodus in Kabbalistic tradition). The text added specific seals for each spirit, absent in Weyer, and developed the ritual procedure more fully. The number seventy-two also matches the claim, found in some Talmudic sources, that Solomon sealed seventy-two kings of demons in a bronze vessel.

The Lemegeton as a whole was compiled in English, with the Goetia forming its first book alongside four others dealing with different categories of spirits: Theurgia-Goetia (spirits of the directional courts), the Ars Paulina (angels of hours and degrees), the Ars Almadel (angels of the four altitudes), and the Ars Notoria (a prayer-based system for acquiring knowledge). Samuel Liddell MacGregor Mathers obtained a manuscript of the Goetia and prepared a working edition, which Aleister Crowley revised and published in 1904, adding a psychological preface influenced by his rationalist and psychological interests.

Content and structure

The seventy-two spirits are organized by rank within an infernal hierarchy. Sixty-nine are ranked as kings, dukes, princes, marquises, presidents, earls, or knights, with specific numbers of legions under their command. The tradition of a military-bureaucratic infernal hierarchy reflects both the political imagination of medieval European court culture and the practical concern of the operator: knowing a spirit’s rank helps determine appropriate forms of address and persuasion.

Each entry follows a consistent structure: name, rank, seal, physical appearance when manifested, number of legions commanded, and area of expertise. The spirits’ competencies range widely. Bael teaches invisibility and rhetoric. Agares makes runaways return and teaches languages. Marbas reveals hidden secrets and causes or cures diseases. Valefor induces theft. Amon reconciles feuding parties. The catalogue as a whole reflects the practical concerns of early modern practitioners: knowledge, influence in human affairs, discovery of hidden things, and occasionally destructive or martial capabilities.

The ritual procedure

The Goetia’s evocation method requires constructing a double circle on the floor with divine names written in the space between the inner and outer rings, and a triangle outside the circle into which the spirit is constrained to appear. The operator stands within the circle, armed with the lamen (a pendant bearing the spirit’s seal), a sword or wand, and a copy of the spirit’s seal prepared in advance. The evocation proceeds through layers of invocation in divine names, escalating from polite address to formal compulsion if the spirit delays in appearing.

This structure encodes the theological premise: the operator uses divine authority, not personal power. The circle protects through sacred names; the triangle constrains through the power attributed to Solomon; the spirit is compelled not by the operator’s will but by the authority of names representing the divine.

Later influence

The Goetia shaped the demonic lore of Western esotericism, appearing in modified form in the work of the Golden Dawn, in Crowley’s Thelemic system, and in countless modern occult texts. Its spirits have become reference points for practitioners exploring demonology, and their sigils appear widely in contemporary magickal art and practice. Jake Stratton-Kent’s multi-volume Encyclopedia Goetia project represents the most rigorous modern scholarly and practical engagement with the tradition.

In myth and popular culture

The Goetia’s parent narrative, King Solomon compelling demons to assist in the construction of the Temple, appears in Jewish, Christian, and Islamic sources. The Talmudic account of Asmodeus, bound by Solomon through a magic ring and set to work, parallels the Goetia’s binding premise. In the Quran, jinn are described as laboring for Solomon at divine command, a tradition elaborated richly in Islamic literature and in the Arabian Nights, where Solomon’s seal is a recurring motif of supernatural authority. The figure of Solomon as master of spirits became one of the most durable images in the mythology of the ancient world.

Johann Weyer, whose Pseudomonarchia Daemonum is the Goetia’s most direct ancestor, presents an interesting cultural paradox. He intended his demon catalogue as evidence that witchcraft accusations were baseless, that those who claimed to work with demons were deluded rather than genuinely malefic. The Goetia used his list for the opposite purpose, as a practical reference for actual spirit work. The same catalogue served both a rationalist debunking of witch persecution and the expansion of a ceremonial demonology.

In the twentieth century, the Goetia entered popular culture through Aleister Crowley’s published edition and through the broader occult revival. Dennis Wheatley’s novels, particularly The Devil Rides Out (1934), presented Goetic-style summoning in a dramatic popular-fiction context that introduced millions of readers to the idea of ritual demonology. The 1968 Hammer film adaptation introduced the imagery to an even wider audience. More recently, the video game series Shin Megami Tensei and its Persona offshoot incorporate the seventy-two spirits alongside demons from other traditions, creating a global pop-cultural presence for Goetic names and seals.

The art of Austin Osman Spare, who developed his own sigil system partly in response to the Goetia’s seal tradition, represents one of the most significant creative responses to the text within the occult community itself. His influence runs through chaos magic into contemporary sigil practice.

Myths and facts

The Goetia is surrounded by misattribution and exaggeration that obscures its genuine historical significance.

• The Goetia is often described as the oldest grimoire, sometimes placed in antiquity. It was compiled in seventeenth-century England from earlier sources; the oldest surviving manuscripts date from that century, and the claim to ancient or Solomonic origin is a convention of the genre.
• Many accounts describe the Goetia as a uniquely dangerous or forbidden text. It was circulated widely in manuscript and print, was known to educated Europeans through Weyer’s published version, and has been commercially available in English since 1904; it is a historical grimoire, not a suppressed secret.
• It is sometimes claimed that Johann Weyer was a practicing magician who used the spirit list himself. Weyer was a physician and a critic of witch persecution; his publication of the demon catalogue was explicitly framed as a skeptical argument against the reality of diabolical pacts, not as a practitioner’s reference.
• Popular accounts often describe the Goetia as containing seventy-two fallen angels, all of whom rebelled against God. The text identifies some spirits by roles implying angelical origin, but others have no such identification; the tradition of describing all seventy-two as fallen angels is an interpretive overlay rather than the Goetia’s own consistent framing.
• A common assumption holds that the Goetia’s protective circle protects against spirits that are inherently and universally malevolent. The grimoire presents the spirits as self-interested and requiring management, not as beings whose sole purpose is harm; the circle defines the terms of the encounter rather than preventing inevitable attack.
