Spirit conjuration, also called evocation, is the ceremonial magic practice of summoning a spirit to appear and speak with the conjurer. Unlike meditation or spirit contact through a medium, evocation is structured, formal, and rule bound: the magician works inside a consecrated circle, calls the spirit into a separate vessel called the triangle of art, and commands rather than invites. Its most famous text is the Ars Goetia, the first book of the Lesser Key of Solomon, the grimoire that catalogues 72 demons with their seals, ranks, and offices.
What evocation is supposed to be
In the traditions that use this practice, spirits, whether called demons, intelligent essences, or archetypal forces, can be contacted and communicated with through ritual. The Goetic frame treats them like a court: kings, dukes, presidents, each with a rank, a seal, and specific things they're said to do, like reveal knowledge, locate lost objects, or teach languages.
Modern practitioners split into two broad camps about what happens. The traditionalist reading treats the spirits as real independent beings. The psychological reading, popularized in the 20th century, treats evocation as a disciplined way of engaging parts of the psyche. Plenty of practitioners hold both at once, which is very much the spirit of the practice: the grimoires themselves are more procedural than theological.
Where conjuration comes from
The famous text, the Lesser Key of Solomon (Lemegeton Clavicula Salomonis), is an anonymously compiled grimoire assembled in the mid-17th century from materials several centuries older. Its first book, the Ars Goetia, draws heavily on Johann Weyer's Pseudomonarchia Daemonum from his De praestigiis daemonum (1570s), with four spirits added and one omitted. The word goetia comes from the Ancient Greek goēteía, meaning charm or witchcraft, and in medieval and Renaissance Europe it was contrasted with theurgy, the nobler art of summoning angels and divine powers.
The rituals themselves trace much deeper. The Testament of Solomon, an early text about Solomon commanding demons with his ring, is the mythic ancestor, and the circle-and-triangle apparatus shows up across the grimoire tradition. Heinrich Cornelius Agrippa's Three Books of Occult Philosophy (1533) supplied the ceremonial framework, defining goetia as the commerce of unclean spirits and setting the stage for a century of manuscript copies, including Thomas Rudd's, which paired the 72 demons with the 72 angels of the Shem HaMephorash as the conjurer's protective counterparts.
The text's modern life began in 1904, when Aleister Crowley published the Mathers edition as The Book of the Goetia of Solomon the King, adding invocations and essays describing the rituals as psychological exploration rather than demon summoning. That framing, spirits as inner forces, is what let evocation move from rare manuscript practice into the wide open modern magical revival, where Goetic work is now a standard part of ceremonial training in orders descended from the Golden Dawn and in independent practice.
How an evocation ritual works
The classical Goetic procedure is explicit, which is part of why it fascinates people: it's the most documented ritual format in Western magic. The traditional setup involves a drawn or constructed circle inscribed with divine names and protection, placed at a distance from a separate triangle of art where the spirit is instructed to manifest. The magician consecrates the space, wears the lamen or breastplate, recites the conjurations, and calls the spirit by name using its seal.
The spirit is bound to appear in the triangle and constrained to answer truthfully. What follows is the actual point of the work: the conversation. The magician asks, the spirit answers, and the magician commands it to depart in peace when done. The grimoires treat the dismissal with as much care as the summons.
Modern practitioners adapt this constantly. Some work with the full apparatus, circle, triangle, seals, consecration. Some reduce it to a candle, the spirit's sigil drawn on paper, and a memorized conjuration. A common contemporary pattern keeps the structure but reframes the spirits as aspects of self, so the ritual becomes an intense guided dialogue. In every version, the constants are preparation, a contained and named vessel for contact, and a formal close.
Common questions
Is Goetic evocation dangerous? The tradition itself says yes, which is why the circle exists. Traditionalists treat the protective apparatus as load bearing and warn against skipping it. Practitioners in the psychological camp describe the risk as psychological instead: the practice is intense, and it can stir up material you weren't ready to meet. Either way, the near-universal advice is the same: don't improvise your first evocation, study the source material, and take the closing banishments seriously.
Do you have to believe in demons? No. A large part of the modern practice treats the spirits as archetypes or autonomous parts of the psyche, a reading that goes back at least to Crowley's 1904 edition. Plenty of practitioners get value from the ritual structure without committing to a literal demon court.
Where do I start? Read the source. Joseph Peterson's digital edition of the Lemegeton, transcribed from the British Library's Sloane manuscripts, is freely available, and his 2001 printed edition is considered the standard. Reading the actual conjurations and seals tells you quickly whether the practice calls to you.
Can you do it alone? Technically the grimoires assume a solitary operator, and many modern practitioners work alone. That said, most experienced magicians recommend some grounding in ceremonial practice first: banishing rituals, meditation, and familiarity with ritual structure before attempting a full evocation.
How long does a ritual take? A full classical evocation, with consecration and the complete conjurations, can run several hours. Modern simplified versions take 30 to 60 minutes. The preparation, constructing or consecrating the tools, often takes longer than the ritual itself.
Is this the same as calling on spirits through a medium? Different format, different power dynamic. Mediumship is usually receptive: information arrives and the medium relays it. Evocation is command-based: the magician summons, questions, and dismisses. The Goetic frame is famously hierarchical, which is what sets it apart from devotional or receptive spirit work.
