Gaap Demon: Powers, Sigil, Enn, Offerings & Attributes
Gaap is one of the most versatile spirits in the Goetic tradition. He appears in both Johann Weyer’s Pseudomonarchia Daemonum and the later Ars Goetia, where he is described as a great President and a mighty Prince commanding 66 legions. His offices are unusually broad: philosophy and the liberal sciences, love and hatred, divination, familiars, swift movement between kingdoms and the power to make people either knowing or ignorant.
That breadth is the reason Gaap deserves a proper profile rather than being reduced to one ritual use. I treat him as a spirit of intelligence, transition and directed influence. When I want the actual summoning procedures, I keep those separate in my Gaap ritual guide. This page is about who Gaap is, what the grimoires actually attribute to him, and how I work with those powers in practice.
Who Is the Demon Gaap?
Gaap appears in Pseudomonarchia Daemonum under the name Gaap or Tap, and later as the thirty-third spirit of the Ars Goetia. Both traditions describe him as a high-ranking spirit with an unusually broad range of offices.
The Ars Goetia calls Gaap a Great President and Mighty Prince. He is said to appear in human form before four kings, functioning as a guide. He teaches philosophy and the liberal sciences, can cause love or hatred, gives true answers concerning past, present and future events, and can move people rapidly from one kingdom to another. He also governs matters involving familiars and the consecration of things belonging to the dominion of Amaymon.
What matters to me is the pattern behind those powers. Gaap repeatedly appears where intelligence, perception, movement and influence meet. He can make someone more knowledgeable or more ignorant. He can create attraction or aversion. He can reveal information or alter a person’s ability to perceive it. That makes him much more interesting than a simple “love demon” or “knowledge demon.”
Gaap’s Main Powers
| Power | Traditional basis | How I interpret it in practice |
|---|---|---|
| Philosophy and liberal sciences | Explicit in the Ars Goetia | Learning, study, intellectual clarity, technical subjects and accelerated understanding |
| Love or hatred | Explicit in the Ars Goetia | Attraction, reconciliation, emotional influence, severance and aversion |
| Past, present and future | Explicit in the Ars Goetia | Divination, strategic foresight and seeing the hidden structure of a situation |
| Making men knowing or ignorant | Explicit in the grimoires | Sharpening or clouding judgment, attention and understanding |
| Swift movement between kingdoms | Explicit in the Ars Goetia | Travel, relocation, transitions, movement through obstacles and rapid changes of position |
| Familiars | Explicit in the Ars Goetia | Spirit relations, spirit mediation and breaking unwanted spirit attachments |
What Gaap Is Best For
I find Gaap most useful when a problem involves more than one layer. If I need simple attraction, there are spirits I would choose before him. If I need simple academic knowledge, there are other demons that specialize more narrowly. Gaap becomes valuable when intelligence, emotion and circumstance are interacting at the same time.
A good example is a competitive professional situation. The problem may involve learning quickly, reading other people’s intentions, adjusting how you are perceived and moving into a better position. Gaap’s offices overlap naturally there. The same is true of complicated social situations where the real issue is not merely “make this person like me,” but understanding what is happening, changing the emotional balance and acting at the right moment.
Gaap’s Sigil
Gaap’s seal is transmitted with his entry in the Ars Goetia. That is the sigil I use as the main visual link to him. The seal matters because it gives the magician a fixed point through which attention can be narrowed onto the spirit rather than onto a vague idea of “a demon.”
I normally place the sigil in the triangle or on the altar during evocation. For attunement, I gaze at it until the lines begin to shift slightly in peripheral vision, then move into the enn or direct invocation. If you want a broader explanation of that method, see my guide to working with demonic sigils.
Gaap’s Enn
The modern enn commonly used for Gaap is:
Deyan Anay Tasa Gaap.
This is a modern demonolatry formula, not a line taken from the Ars Goetia or Weyer’s text. I still find it useful because an enn does not need to be ancient to function as an attunement device. Its job is to stabilize attention on the spirit and push the mind toward the receptive state needed for contact.
I use the enn before evocation rather than treating endless repetition as the ritual itself. Once the atmosphere changes and the sigil feels “active,” I move into direct communication.
How Gaap Appears
The grimoires describe Gaap in human form, going before four powerful kings. That description is important because it is more restrained than many of the animal-hybrid forms associated with other Goetic spirits.
In my own work, Gaap has appeared as a tall, slim figure in dark robes with a pronounced red or heated quality around him. I do not present that as the only form he takes. Spirit manifestation is filtered through the magician’s own perceptual system, so another practitioner may receive a very different image while still making genuine contact.
I pay more attention to consistency than appearance. If the same presence returns with the same emotional pressure, voice, manner of communication and symbolic themes across different workings, that pattern matters more than whether two magicians describe identical clothing or facial features.
Gaap and Knowledge
Gaap’s intellectual office is one of the clearest parts of his traditional description. He teaches philosophy and the liberal sciences. In practical terms, I use that current for difficult study, understanding abstract material, connecting ideas that previously seemed unrelated and seeing the underlying structure of a subject.
This is not passive “make me smart” magic. I get better results when the ritual is tied to an actual field of study, project or problem. Asking Gaap for mastery of a defined subject gives the spirit something concrete to work through. The magical work and the actual study should then reinforce one another.
Gaap for Divination and Hidden Knowledge
The Ars Goetia says Gaap answers truly concerning things past, present and to come. That places him naturally within divinatory work.
I prefer using him for strategic questions rather than trivial fortune telling. Questions such as “What is the real obstacle in this situation?”, “What am I failing to see?” or “Which path gives the strongest outcome?” make better use of his intelligence than simply asking for random predictions.
A black mirror works particularly well here because it allows the divinatory and evocational aspects of the operation to overlap. Gaap is called, the question is stated, and the mirror becomes the medium through which symbols or direct impressions are received.
Gaap for Love, Attraction and Aversion
Gaap’s ability to cause love or hatred is explicitly part of the old grimoire description. I read that office more broadly as control over emotional orientation. Love and hatred are the extreme poles, but between them are attraction, fascination, trust, indifference, avoidance and resentment.
That makes Gaap useful when the emotional structure of a relationship or group needs to change. I still separate this from his intellectual work in ritual because the atmosphere is different. Venusian symbolism may support attraction work, while darker Saturnian or martial symbolism can be used when the aim is separation or cooling.
The important point is that these are applications layered onto Gaap’s traditional office. They are not proof that medieval grimoires assigned him Venus, copper, a specific crystal or a particular candle color.
Planetary and Elemental Associations
This is where modern sources become messy. The old grimoires give Gaap ranks and offices, but they do not provide the tidy modern correspondence chart that websites often repeat as if it were ancient fact.
I therefore treat planetary forces as ritual modifiers rather than permanent labels. For knowledge, communication and travel, Mercury is an obvious supporting current. For attraction, Venus can be introduced. For restriction, confusion or severance, Saturn can be appropriate. This is more useful than pretending Gaap belongs exclusively to one planet when his traditional powers clearly cross several domains.
The same principle applies to elements. I do not consider “Gaap equals Water” a fixed traditional fact. If water is useful to a particular operation, I use it deliberately. If the work is intellectual and Mercurial, air and movement may fit better. The request should determine the supporting symbolism.
Offerings to Gaap
I prefer offerings that reflect intelligence, movement and deliberate effort. Incense is always suitable because it changes the ritual atmosphere without distracting from the work. Wine can be used for formal evocation. Dedicated study, writing or completing a difficult intellectual task in Gaap’s name can also be a strong offering because it directly mirrors one of his main offices.
For knowledge work, I may place a book, diagram or tool connected with the subject near the sigil. For divination, the offering can accompany a black mirror or other scrying device. For travel or transition work, a key or map can serve as a ritual symbol.
I do not recommend using elemental mercury or other toxic substances simply because a modern correspondence chart links Gaap with Mercury. Symbolic planetary correspondences do not require physically handling hazardous material.
Attunement to Gaap
Attunement is shorter and more receptive than evocation. Place the sigil in front of you, light incense, enter a light trance and repeat Deyan Anay Tasa Gaap while keeping your attention on the seal. Stop once the atmosphere shifts and remain receptive.
The purpose is familiarity. Over repeated sessions you learn how Gaap’s current feels before making larger requests. That makes later evocation cleaner because you already know the difference between ordinary imagination and the characteristic pattern of the spirit.
If trance is difficult, practice it separately first. My guide on how to enter a trance state is more useful than piling additional ritual objects onto a weak altered state.
How to Summon Gaap
I keep the full summoning work separate from this profile because Gaap has enough distinct powers to justify more than one ritual approach. My dedicated guide includes operations built around different goals rather than forcing every request into the same ceremony.
You can read the complete instructions here: How to Summon Gaap: 3 Rituals.
Gaap and Other Demons
Gaap combines well with spirits whose offices fill a missing part of the operation. For intellectual work, I would consider spirits such as Furcas when disciplined study and formal knowledge are central. For deeper occult knowledge, Astaroth can complement Gaap well.
I do not stack spirits simply because more names look more impressive on an altar. Each spirit should have a defined role. Gaap should be used because one of his offices is actually necessary to the working.
Final Thoughts on Gaap
Gaap is easy to underestimate because his powers do not fit into one neat category. That is exactly what makes him valuable. He can sharpen understanding, alter emotional dynamics, reveal hidden information and assist with movement or transition. Few Goetic spirits cover that much territory without becoming completely unfocused.
If I had to reduce his current to one idea, it would be directed intelligence in motion. Gaap helps the magician understand what is happening, alter the balance of a situation and move from one state into another with greater control.
