Orobas is a demon described in medieval grimoires like The Lesser Key of Solomon (also known as the Ars Goetia), where he ranks as the 55th spirit. He appears as a horse but can take human form, and he’s said to be truthful, loyal to summoners, and knowledgeable in matters of the past, present, future, divinity, and the liberal sciences. Traditionally, he’s invoked for honest answers, protection from deception, and gaining favor with friends or foes. Note that these rituals are rooted in Western occultism and are not scientifically verified; they carry risks in folklore, like spiritual backlash if mishandled.

Preparation for Summoning

Before attempting any ritual, traditional sources emphasize mental, physical, and spiritual readiness. This is not casual—it’s framed as a pact with a powerful entity.

Purification and Fasting: Abstain from meat, alcohol, and sex for 3–9 days to cleanse your body and mind. Bathe in saltwater or herbal infusions (e.g., hyssop, frankincense) to purify aura.
Tools and Circle Setup:
Magic Circle: Draw a protective circle (9 feet in diameter) on the ground using chalk, salt, or flour. Inside, inscribe a triangle of art (an equilateral triangle) where the spirit manifests. Use Solomon’s pentacles or seals (Orobas’s sigil is a specific geometric design—search for “Orobas sigil” for visuals).
Sigil of Orobas: Obtain or draw his seal from the Ars Goetia. Engrave it on virgin parchment or metal (gold or silver preferred).
Incense and Offerings: Burn frankincense, myrrh, or sandalwood. Offerings might include white wine, bread, or a black mirror for scrying.
Robes and Tools: Wear white linen robes. Have a black-handled knife (athame), wand, and grimoire handy. Perform at midnight during a waxing moon, ideally on a Tuesday (Mars day, for his martial associations).
Location: A secluded room or outdoor space with no interruptions. Face east, the direction of invocation.

The Summoning Ritual (Step-by-Step)

This is a simplified adaptation from the Ars Goetia and related texts like the Pseudomonarchia Daemonum. Recite invocations in a firm, commanding voice. Stay within the circle—never step out until dismissal.

Preliminary Invocation:
Enter the circle clockwise, thrice-repeating: “I conjure thee, O Spirit [Orobas], by the power of the Most High, Adonai, Elohim, and the hosts of heaven, to appear before me in fair and comely shape, without harm or terror.”
Light incense and trace Orobas’s sigil in the air with your wand.
Main Conjuration:
Recite the full call (abridged here for brevity; full versions are in grimoires):

“Orobas, great and mighty prince of the infernal regions, I summon and command thee by the name of the Eternal, the Tetragrammaton, YHVH, and by the seals of Solomon, to come peaceably and visible unto me. Thou who knowest all things hidden and revealed, appear now in this triangle, in a form pleasing to my sight, and answer truly all that I shall ask.”

Visualize a horse galloping from the shadows, transforming into a nobleman. Gaze into the triangle or scry in the mirror.
Binding and Questioning:
Once manifested (signs include horse-like sounds, warm winds, or visions), bind him: “I bind thee, Orobas, by the power of these names, to speak truth and cause no ill.”
Ask questions directly (e.g., “Reveal the truth of [matter]”). He reportedly cannot lie to a prepared summoner.
Limit to 3–7 questions to avoid fatigue.
Dismissal:
Thank him: “I thank thee, Orobas, for thy presence and wisdom. Depart now in peace to thine abodes.”
Extinguish incense and erase the circle counterclockwise. Bury or burn any remnants.

Warnings and Variations

Risks: Grimoires warn of madness, possession, or attacks if the circle breaks or intent is impure. Modern occultists (e.g., in Chaos Magick) adapt this with visualization only, skipping tools, but traditionalists insist on full setup.
Ethical Note: This is ceremonial magic, not endorsement. If exploring, consult experts like those in the Ordo Templi Orientis or read The Goetia by Aleister Crowley for annotated versions.
