A grimoire keeper once traced the seal of Marchosias onto parchment at midnight, following the exact lines from a 17th-century manuscript. The ink dried unevenly. The circle wavered. He lit a single candle and sat with the drawing for hours, waiting for something to shift. Nothing did. That is the honest beginning of most work with the Goetic seals: the symbol does not perform. It positions.
The Seal of Marchosias is the unique identifying sigil of the 35th spirit in the Ars Goetia, a demonic marquis who appears as a wolf with griffin’s wings and a serpent’s tail, breathing fire. The seal is the operator’s key to commanding the spirit within the protective triangle of Solomon. Without it, the conjuration is incomplete.
This article covers the seal’s origin in the Lesser Key of Solomon, its precise geometric structure, the contested symbolism of its lines, how it has been used in practical evocation, and the most common errors practitioners make when drawing it.
Where the Seal of Marchosias First Appears in the Record
The earliest surviving manuscript of the Ars Goetia is the Harley MS 6483, dated to the early 1600s and held in the British Library. It contains 72 seals drawn in brown ink, each corresponding to a named spirit. Marchosias appears on folio 30 verso, labeled as the 35th spirit, a marquis who commands 30 legions of infernal spirits.
The seal was not invented by the manuscript’s author. It was copied from earlier sources. The Lemegeton Clavicula Salomonis (the Lesser Key of Solomon) circulated in various forms from the 15th century onward, drawing on medieval Arabic and Jewish magical traditions. The seals themselves likely derive from the Clavicula Salomonis tradition, where each spirit’s name was encoded into a geometric figure through a process of letter-to-symbol transformation known as gematria or notarikon.
By the time Samuel Liddell MacGregor Mathers and Aleister Crowley published the Goetia: The Lesser Key of Solomon in 1904, the seal of Marchosias was standardized. Mathers transcribed it from the Harley manuscript. Crowley added an introduction. Their edition became the basis for nearly all modern Goetic practice.
The seal has not changed in its essential form for over four centuries. That stability matters. In ceremonial magic, a seal is not a decoration. It is a contract.
What the Seal of Marchosias Actually Looks Like
The seal consists of a central vertical axis with two horizontal crossbars, creating a shape that resembles an elongated cross or a stylized key. At the top, a small circle sits above the first crossbar. Below the second crossbar, the line terminates in a curved hook that curls to the left.
Five distinct elements compose the seal:
- A top circle approximately one-third the width of the crossbars
- An upper horizontal bar intersecting the vertical line
- A lower horizontal bar set below the first, roughly the same length
- A vertical stem connecting all elements
- A terminal hook at the bottom, curving left
The proportions are not arbitrary. The circle sits above the upper bar by a distance equal to the bar’s thickness. The two bars are parallel. The hook’s curve follows a quarter-circle arc. These ratios were likely calculated through the same letter-number correspondences that generated the seal from Marchosias’s name.
In the Harley manuscript, the seal is drawn with a single continuous line. No breaks. No overlapping strokes. The line begins at the top circle and ends at the hook. This continuous line is the spirit’s path from its realm into the operator’s circle. A broken seal is a blocked door.
The Symbolism Hidden in the Geometry
The seal of Marchosias encodes three layers of meaning: the spirit’s rank, its nature, and its function.
The top circle represents the spirit’s authority as a marquis. In the Goetic hierarchy, marquises command legions and serve under kings. The circle is the seal of that office, analogous to the coronet in heraldry. It is open at the bottom, not closed, indicating that the spirit’s authority derives from a higher power (the king it serves).
The two crossbars correspond to the dual nature of Marchosias. The spirit appears as a wolf (cunning, predation, the hunt) with griffin’s wings (divine guardianship, the union of earth and sky). The upper bar may represent the wolf’s earthly domain. The lower bar, the griffin’s aerial reach. Together they form a balance: the spirit moves between two worlds.
The terminal hook is the most debated element. Some practitioners interpret it as a shepherd’s crook, indicating Marchosias’s role as a guide or protector. Others see it as a sickle, suggesting the spirit’s association with judgment or harvest. A third reading ties it to the serpent’s tail described in the spirit’s appearance: the hook is the tail, curling back toward the source.
The seal as a whole resembles a key. That is not coincidence. The Goetic seals are often called the keys of Solomon, and each one unlocks a specific spirit. Marchosias’s seal is a literal key to his particular legion.
How the Seal Has Been Used in Practice
The seal serves three distinct functions in Goetic evocation: identification, authority, and containment.
Identification. The seal is drawn on parchment or virgin paper (paper never used for any other purpose) and placed within the triangle of Solomon. When the spirit appears, it must match the seal. If it does not, the operator dismisses it. This protects against impersonation by lesser spirits.
Authority. The operator holds the seal or places it on the circle’s boundary. The seal is the physical representation of the operator’s command over the spirit. Without it, the spirit has no obligation to obey. With it, the spirit is bound by the covenant of Solomon.
Containment. In some traditions, the seal is drawn on the spirit’s vessel (a brass or clay container) to trap the spirit after the evocation. This is rare in modern practice but appears in the Clavicula Salomonis manuscripts.
The actual procedure, as described in the Ars Goetia, requires the operator to draw the seal during a specific planetary hour, using consecrated ink and a virgin pen. The seal is then fumigated with incense appropriate to the spirit (frankincense for Marchosias, according to some sources). The operator recites the spirit’s name and rank while tracing the seal’s lines.
A common error: drawing the seal inside the circle rather than in the triangle. The seal belongs in the triangle. The circle is the operator’s protected space. The triangle is the spirit’s designated area. The seal sits between them.
How Marchosias’s Seal Compares to Other Goetic Seals
The seal of Marchosias shares structural features with other marquises in the Goetia. Andras (63rd spirit) has a similar vertical stem with crossbars. Andrealphus (65th) uses a comparable hook. But Marchosias’s seal is distinct in its simplicity.
Most Goetic seals are dense with loops, dots, and intersecting lines. The seal of Buer (10th spirit) has five radiating spokes. The seal of Vassago (3rd spirit) uses three concentric circles. Marchosias’s seal is sparse by comparison. Five elements. No loops. No dots. No intersections.
This simplicity may reflect the spirit’s nature. Marchosias is described as a truthful spirit who gives reliable answers about past, present, and future. The seal’s directness mirrors that honesty. A spirit that does not deceive does not need a complex seal.
The seal also lacks the planetary or zodiacal symbols that appear on other Goetic seals. The seal of Orobas (55th spirit) includes a crescent moon. The seal of Gusion (11th spirit) bears a star. Marchosias’s seal has none of these. It is pure geometry, stripped of astrological reference.
Common Misconceptions About the Seal
The seal is not a summoning device. Drawing the seal alone does not call the spirit. The seal is a component of a larger ritual that includes prayers, invocations, and the construction of the circle and triangle. The seal without the ritual is a drawing.
The seal is not a protective amulet. Some modern practitioners wear the seal as a talisman. The Goetic tradition does not support this. The seal is a tool of command, not protection. Wearing it may attract the spirit’s attention without the proper containment.
The seal does not need to be drawn in blood. This is a Hollywood invention. The manuscripts specify ink made from lampblack and gum arabic, or consecrated water and earth. Blood is never mentioned. The requirement is purity, not sacrifice.
The seal is not unique to Marchosias. Each of the 72 spirits has its own seal. They are not interchangeable. Using the wrong seal is an invitation to chaos.
The seal does not change. Despite what some modern grimoires claim, the seal has remained consistent across all major manuscript traditions. Variations appear only in poorly copied editions. The Harley manuscript is the authoritative source.
FAQ
Can I draw the seal of Marchosias without performing the ritual? Yes, but it has no effect. The seal is a ritual object, not a magical battery. Drawing it without the corresponding conjuration is an exercise in geometry, not magic.
What happens if I draw the seal incorrectly? The spirit may not appear, or a lesser spirit may impersonate it. The seal must match the manuscript exactly. Even a slight deviation in proportion or line direction invalidates it.
Do I need to destroy the seal after the ritual? Some traditions recommend burning the seal after the spirit is dismissed. Others keep it for future use. The manuscripts do not specify. The choice depends on the operator’s tradition.
Is the seal of Marchosias dangerous? The seal itself is inert. The danger lies in the ritual context. If the operator fails to properly contain the spirit, any Goetic evocation carries risk. The seal is a tool, not a weapon.
The Seal as a Living Tradition
The seal of Marchosias has survived four centuries of copying, translation, and reinterpretation. It appears in the Harley MS 6483, in Mathers and Crowley’s 1904 edition, and in countless modern grimoires. It has been drawn on parchment, carved into brass, and tattooed onto skin. Through all of that, its form has not changed.
That stability is rare in occult practice. Most symbols shift with each generation. The seal of Marchosias holds its ground. It is a fixed point in a tradition that otherwise evolves constantly.
For the practitioner, that means the seal is reliable. What worked for a 17th-century magician in London works today. The same lines. The same proportions. The same spirit.
