The Power Being Addressed
Ose is approached as Fifty-seventh spirit of the Ars Goetia, a Great President commanding thirty legions.
Ose is intelligent, mercurial and psychologically invasive. He teaches sciences and true knowledge, yet is also associated with changing identity and making a person believe they have become something else.

Why the Rite Exists
The rite creates a controlled threshold between ordinary life and the domain attributed to Ose. Preparation separates the practitioner from ordinary noise. The sigil and name establish the centre. The petition directs the encounter. The offering defines exchange. Dismissal restores the chamber to ordinary time.
A rite without preparation is only demand. A rite without closure is pressure without a boundary.
Personality and Ritual Conduct
Ose is intelligent, mercurial and psychologically invasive. He teaches sciences and true knowledge, yet is also associated with changing identity and making a person believe they have become something else.
The practitioner should enter with one clear purpose and avoid contradictory requests. The entity's rank and temperament determine the tone. Respect does not mean submission, and command does not mean theatrical aggression.
The Atmosphere of Manifestation
The impression of a stalking animal may circle the room. Spotted shadows, sudden shifts in self-perception and a human voice emerging from predatory silence may accompany the manifestation.
Manifestation may begin before any full figure is seen. Sound, temperature, dream, bodily pressure, altered flame, animal imagery or a complete inner sentence may mark the transition from preparation into contact.

The Rite: Full Ceremonial Sequence
The following material preserves the original SatanWorld article's ritual content without omitting its operative details.
Ose (also known as Oso or Osé) is the 57th spirit described in the Ars Goetia, the first section of the 17th-century grimoire The Lesser Key of Solomon. He is depicted as a leopard that, at the summoner's command, transforms into a man. Ose is said to grant powers such as teaching liberal sciences (like logic, philosophy, and arts), granting true knowledge, and enabling invisibility. He commands 30 legions of spirits and is considered a President in the infernal hierarchy. These attributes come from traditional demonological texts, but summoning is presented as a ritualistic exercise, not literal fact.
Traditional Method to Summon Ose
Summoning rituals from the Ars Goetia follow a structured, ceremonial process rooted in Solomonic magic. This is not advice for practice—it's a historical and cultural description. The ritual requires preparation, tools, and invocations. Below is a step-by-step outline based on the grimoire's instructions.
Preparation
Timing and Location: Perform during the hour of Ose (traditionally the 10th hour of the day or night, depending on planetary hours—Mercury or Venus days are ideal). Choose a secluded, purified space, ideally a triangle of art drawn on the ground with chalk or blood (symbolic, not literal harm).
Tools Needed
A magic circle (9 feet in diameter) inscribed with divine names (e.g., Tetragrammaton, Adonai).
A triangle outside the circle for the spirit to appear.
Incense: Sandalwood or frankincense.
Robes: White linen for purity.
A black mirror or scrying crystal for evocation.
The seal of Ose (a sigil resembling a leopard's head with astrological symbols; draw it on virgin parchment with ink mixed with your blood or dragon's blood resin).
The Ritual
Purification and Protection: Bathe in holy water (saltwater or herbal infusion). Fast for 24 hours prior. Recite Psalms 8, 18, or 91 for protection against harm.
Enter the Circle: Face east, light candles at the quarters (white for east, red for south, etc.). Burn incense and anoint the seal with oil.
Invocation: Recite the Preliminary Invocation from the Lesser Key (a call to the divine powers), then the specific call to Ose:
"I do invocate and conjure thee, O Spirit Ose; and being with power armed from the Supreme Majesty, I do strongly command thee, by Beralanensis, Baldachiensis, Paumachia, and Apologiae Sedes; by the most Powerful Princes, Genii, Liachidae, and Ministers of the Tartarean Abode; and by the Chief Prince of the Seat of Apologia in the Ninth Legion, I do invoke thee, and by invocating conjure thee. And being armed with power from the Supreme Majesty, I do strongly command thee, by Him Who spake and it was done, and unto whom all creatures be obedient… Appear thou now before this Circle in a fair human shape, without any deformity or tortuosity. Come thou in and from any part of the world wherever thou mayest be, and make rational answers unto all things I shall demand of thee. Come thou peaceably, visibly, and affably, now, and without delay, manifesting that which I shall desire. For thou art conjured by the Name of the Living and True God, Helioren, wherefore fulfil thou my commands, and persist thou therein unto the end, and according to mine interest, visibly and affably speaking unto me with a voice clear and intelligible without any ambiguity."
Repeat three times, vibrating the name "OSE" (pronounced "OH-say").
Appearance and Binding: Ose will manifest in the triangle as a leopard or man. Use the seal to bind him—hold it aloft and command obedience. Ask questions or request boons (e.g., "Teach me the arts of invisibility").
Dismissal: Thank the spirit, then banish with: "O thou Spirit Ose, because thou hast diligently answered unto my demands, and hast been very ready and willing to come at my call, I do here license thee to depart unto thy proper place; without causing harm or danger unto man or beast. Depart, then, I say, and be thou very ready to come at my call, being conjured by the Name of the Eternal. Amen."
Closing: Extinguish candles counterclockwise, dismantle the circle, and bury or burn the seal.
Variations in Sources
In some editions of the Lesser Key, Ose is linked to the planet Mercury, so incorporate mercury-related symbols (e.g., a wand tipped with quicksilver).
Modern occult adaptations (e.g., in chaos magic) simplify this to meditation on the sigil with visualization, omitting tools for safety.
Ritual Architecture
Separation
Bathing, silence, fasting, abstinence, darkness or isolation signal that ordinary time has been left behind. The preparation should be coherent rather than assembled from random gestures.
Construction of the Chamber
Candles, incense, circle, salt, water, metals, herbs, stones and offerings organize the room around the office of Ose. Each item should perform one function.
Establishing Contact
The sigil, name, chant or enn becomes the visual and verbal axis of the operation. Repetition narrows attention until the chamber feels organized around one intelligence.
The Petition
The petition should contain one principal request, one boundary and one completion condition. Ambiguous wishes invite expansion.
Recognition of Presence
The central phase begins when the atmosphere changes in a sustained way. Pressure, heat, cold, altered flame, internal speech, animal forms or dreamlike imagery may mark the crossing.
Offering and Exchange
The offering represents reciprocity. It may carry the entity's color, office, appetite or symbolic domain. A promise should never be made casually.
Dismissal and Return
The operation ends only when Ose is thanked or dismissed according to the preserved method. Candles are extinguished safely, the chamber aired where appropriate and the result written before sleep or distraction changes memory.
Instruments and Their Symbolism
The sigil acts as the visual body of the name. The candle establishes color, rank and duration. Incense gives density to the air. Salt or the circle defines limits. Water reflects and carries emotional force. Metal, stone, herb or coin embodies office.
More objects do not automatically create more power. A crowded altar can divide attention.
Timing and Correspondence
Where several systems appear, one coherent system should govern the operation.
Manifestation Signs
Signs associated with Ose include:
- a sustained shift in the chamber's emotional pressure;
- dreams repeating the spirit's form or office;
- unusual candle movement without a matching draft;
- sounds, smells or bodily sensations consistent with the entity;
- a complete phrase arising inside thought;
- external events beginning to mirror the petition;
- fear, attraction or resistance intensifying at the moment of contact.
A repeated pattern across chamber, dream and aftermath carries greater weight than one isolated sign.
The Frightening Edge of the Rite
Ose's greatest danger is instability of identity. Insight can become delusion, invisibility can become dissociation and transformation can erase the seeker's ordinary sense of self.
The deepest danger is transformation that feels useful. The practitioner may begin to imitate the spirit's temperament, organize life around the petition or interpret every event as part of the operation.
Failure Patterns
Failure appears when preparation is abandoned, the request changes repeatedly, symbols are mixed without purpose, panic replaces attention, impossible offerings are promised or the practitioner refuses to close because no dramatic apparition appeared.
Failure can also appear as excess success: the requested current enters ordinary life faster than expected.
Boundaries of the Petition
The petition should state what is requested, where the result may operate, what form the result may take and what event marks completion. Knowledge can destroy innocence. Protection can become isolation. Transformation can become instability. Treasure can become obsession.
The wording is therefore part of the danger.
Completion and Aftermath
The rite is complete when the petition has been spoken, the exchange acknowledged, the presence dismissed and the chamber returned to ordinary order.
Record the date, timing, preparation, tools, words, signs, dreams, first external movement, emotional changes and fulfillment of any promised offering.
The aftermath belongs to the rite. Results may arrive as opportunity, conflict, warning, sudden knowledge, disappearance of an obstacle or an intensification that reveals the true shape of the request.
The Inner Ordeal
The rite of Ose is also an ordeal of resemblance. The chamber reveals where the spirit's office already exists inside the seeker's life.
The frightening moment is often recognition rather than apparition. The seeker discovers that the request has already shaped behavior before the first candle was lit.
The Return to Ordinary Life
After closure, eat, drink, wash, change clothing, step outside or speak with another person. These acts declare that ritual time has ended.
Do not repeat the operation immediately because silence feels uncomfortable.
Final Warning
Ose's greatest danger is instability of identity. Insight can become delusion, invisibility can become dissociation and transformation can erase the seeker's ordinary sense of self.
Do not leave the altar active indefinitely. Do not continue chanting after dismissal. Do not add a second petition during closure.
