Sitri (also spelled Sytry or Bitru) is the 12th spirit in the Ars Goetia, a grimoire section of the 17th-century Lesser Key of Solomon. He is depicted as a leopard-headed prince riding a gryphon, who can transform into a handsome human form. Sitri is said to specialize in revealing secrets of love, inciting lustful passions between people (including same-sex desires), and causing women to reveal their naked forms or confess hidden truths. He commands 60 legions of spirits and is associated with air elementals. These descriptions stem from medieval occult traditions, blending demonology with Renaissance magic.
Note: Summoning rituals are historical/esoteric practices, not scientifically verified. They carry symbolic, psychological, or cultural weight but no guaranteed supernatural outcomes. Approach with personal discernment, as interpretations vary widely in modern occultism (e.g., chaos magic views them as archetypes rather than literal entities).

Preparation for Summoning
Traditional Goetic rituals emphasize purity, intent, and protection to avoid unintended consequences. Here’s a step-by-step overview based on the Lesser Key of Solomon and related texts like the Pseudomonarchia Daemonum by Johann Weyer:

Gather Materials:

A consecrated circle: Draw a 9-foot diameter circle on the ground using chalk, flour, or salt. Inscribe protective symbols inside, such as the Triangle of Art (an equilateral triangle outside the circle for the spirit to appear in) and names of power (e.g., Adonai, Elohim).
Tools: Black-handled knife (athame) for tracing the circle; incense of frankincense or myrrh; a black mirror or scrying stone for evocation; virgin parchment or paper inscribed with Sitri’s sigil (a complex glyph resembling intertwined loops—search for “Sitri sigil Ars Goetia” for visuals).
Offerings: Suitable for Sitri include red wine, honey, or symbolic items evoking passion (e.g., roses or mirrors). Avoid animal sacrifice, as modern adaptations omit this.


Timing and Location:

Planetary hour: Sitri aligns with Venus (love/lust), so perform during a Venus hour (use an astrological calculator; e.g., Friday dawn or dusk).
Lunar phase: Waxing moon for attraction rituals.
Space: A quiet, undisturbed room at night. Face east (direction of air spirits).


Mental and Physical Prep:

Fast for 24 hours or abstain from sex to heighten focus.
Bathe in salt water for purification.
State your intent clearly: e.g., “I seek Sitri’s aid in matters of desire and revelation, under my command.”



The Summoning Ritual
This is a condensed version adapted from the Ars Goetia’s evocation formula. Perform solo or with a trusted assistant. Total time: 1-2 hours.

Cast the Circle:

Stand outside the circle. Trace it clockwise with the athame while reciting: “I conjure thee, O Circle of Art, by the power of the Most High, that thou shalt contain all spirits and protect me from harm.”
Step inside and seal it counterclockwise.


Preliminary Invocation:

Light incense. Recite the Preliminary Invocation (from the Lesser Key):

“O Thou, the great and mighty God, who art the Lord of all spirits, I beseech Thee to send Thy servant Sitri before me, that he may appear visible and affable, in a fair and comely shape, without deformity or horror.”

Call Sitri Specifically:

Hold his sigil aloft. Chant his enn (a modern demonic calling phrase): “Lirach Alora vefa Sitri” (repeat 3-11 times, vibrating the sounds).
Full conjuration (abridged):

“I do invocate and conjure thee, O Spirit Sitri, 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 terror. Come thou peaceably, visibly, and affably, now and without delay, manifesting that which I shall desire.”

Appearance and Binding:

Gaze into the scrying tool. Sitri may manifest as visions, feelings of heat/arousal, or auditory whispers.
If he appears, command: “Sitri, I bind thee by the power of the pentagram and the names of the Most High. Thou shalt answer truly and depart peaceably when dismissed.”
Ask your questions (e.g., “Reveal the secrets of [person’s] affections” or “Incite passion between [names]”). Keep it concise—Goetic spirits dislike verbosity.


Dismissal:

Thank him: “I thank thee, Sitri, for thy obedience. Depart now in peace to thy abodes.”
Recite: “O Thou, the glory of the God of Israel, the mighty God, the Lord of Hosts… Depart ye, O Spirits, unto your places.”
Erase the circle counterclockwise. Bury or burn any remnants.



Variations and Modern Adaptations

Solomonic Lite: Skip the full circle; use meditation with the sigil while visualizing Venusian energy.
Chaos Magic: Treat Sitri as a thoughtform—create a servitor embodying lust, charged via sigil magic.
Safety Tips: If discomfort arises (e.g., intense emotions), banish with the Lesser Banishing Ritual of the Pentagram: Trace pentagrams in air while vibrating “YHVH” (Yod-Heh-Vav-Heh).
Warnings from Texts: The Ars Goetia cautions that without proper command, spirits like Sitri may deceive or inflame uncontrolled desires. Historical accounts (e.g., in The Book of Abramelin) stress humility.
