A medieval magician sits at his desk, a brass compass in one hand, a quill in the other. He is not drawing a picture. He is constructing a seal that will bind a planetary intelligence to his will. Across the room, a different manuscript lies open: the Lemegeton Clavicula Salomonis, showing a sigil that looks like a child’s doodle of a bird. Both are sacred. Both are dangerous. But they belong to different worlds.
Goetia sigils and planetary seals are two distinct classes of magical symbols, often conflated by modern practitioners. The key difference: Goetia sigils are signatures of specific spirits, while planetary seals are geometric representations of celestial forces. One is a name given form. The other is a map of influence.
Where Do These Symbols Come From?
The two families of symbols emerged from different currents of Western ceremonial magic, separated by centuries and by intent.
Planetary seals trace their roots to Hellenistic astrological magic, codified in texts like the Picatrix (an 11th-century Arabic grimoire translated into Latin in 1256) and later systematized by Heinrich Cornelius Agrippa in his Three Books of Occult Philosophy (1533). Agrippa assigned each of the seven classical planets a seal: a geometric figure composed of lines, circles, and astrological glyphs. These seals were not invented by any single author. They were derived from the numerical squares (kameas) associated with each planet, where the sum of numbers in any row or column equals the same total. The seal of Jupiter, for example, emerges from the 4x4 square of Jupiter, its lines tracing the positions of key numbers.
Goetia sigils come from a different source. The Ars Goetia, the first book of the Lemegeton (compiled around the 17th century, though drawing on earlier material), contains 72 sigils for 72 spirits. Each sigil is a unique, often asymmetrical design that functions as the spirit’s personal signature. The earliest known manuscript of the Lemegeton dates to 1641 (Sloane MS 3825 in the British Library), but the sigils themselves likely circulated in earlier forms. Johann Weyer included many of them in his Pseudomonarchia Daemonum (1563), though without the full ritual framework. The sigils were later popularized by Aleister Crowley in his 1904 edition of The Goetia.
That history matters because it explains why the two symbol sets look so different. Planetary seals are mathematical. Goetia sigils are calligraphic.
How You Draw a Goetia Sigil vs a Planetary Seal
The difference in construction reveals the difference in purpose.
A planetary seal is drawn using a compass and straightedge, often on a square of metal or parchment corresponding to the planet. The seal of Saturn, for instance, is built from the 3x3 kamea of Saturn: three lines crossing at specific angles, with the planetary glyph at the center. The process is precise. A mistake of a single degree breaks the seal’s correspondence. The magician works during the planetary hour of that planet, on the appropriate day (Saturday for Saturn, Thursday for Jupiter, and so on). The seal is then consecrated with incense, oil, and the recitation of the planetary psalm.
A Goetia sigil is drawn freehand, usually in black ink on white paper or virgin parchment. The sigil for Bael (the first spirit of the Ars Goetia) shows three crowned heads, each facing a different direction, connected by a single line. The sigil for Paimon resembles an inverted crown with two curving horns. There is no geometric formula. The sigil is the spirit’s name written in a cipher, often derived from the Hebrew alphabet or from a system of magical squares called the “Ring of Solomon.” The magician does not invent the sigil. He copies it exactly from the manuscript, then consecrates it by placing it inside a triangle of art and invoking the spirit by name.
The fire is not decoration. It is the altar. The planetary seal is placed on the altar during the ritual. The Goetia sigil is drawn on the ground or on a parchment that the magician holds.
What Each Symbol Actually Does in Ritual
Planetary seals and Goetia sigils serve different functions in practice, and confusing them can produce weak results.
A planetary seal is a focus for a celestial force. The magician uses it to attract the influence of a planet: Jupiter for expansion and wealth, Venus for love, Saturn for binding. The seal is not a spirit. It is a channel. You do not command the seal. You align yourself with it. In the system of Agrippa, the seal is worn as an amulet, placed in a talisman, or drawn on the floor of the ritual space. It works by sympathy: the seal’s geometry resonates with the planetary sphere, drawing that energy down into the material world.
A Goetia sigil is a summons for a specific spirit. The sigil is the spirit’s name in a form that compels it to appear. In the Ars Goetia, the magician shows the sigil to the spirit within the triangle of art, commanding it to obey. The sigil is not a passive channel. It is an active binding. The spirit’s name is written on the sigil, and the magician’s will is projected through it. If the sigil is destroyed, the spirit is released.
That difference explains why the two are used in different contexts. A planetary seal can be worn for weeks. A Goetia sigil is typically destroyed after the ritual, or stored in a sealed container.
Why People Confuse Them
The confusion is understandable. Both are circular or geometric designs. Both appear in grimoires. Both are called “seals” in some translations. But the conflation leads to practical errors.
One common mistake: using a Goetia sigil as a talisman for protection. The sigil of a demonic spirit is not a protective symbol. It is a summoning symbol. Wearing it without the proper ritual framework is like leaving a door open with no one inside. The planetary seal of Saturn, by contrast, is used for binding and protection precisely because it channels a force that is restrictive and defensive.
Another mistake: assuming planetary seals are “safer” than Goetia sigils. Planetary seals are not inherently safe. The seal of Mars, used incorrectly, can attract conflict and injury. The seal of Saturn can bring depression and limitation. The force is neutral. The magician’s intent determines the result.
A third misconception: that all sigils are derived from the same system. They are not. Goetia sigils come from a Judeo-Christian demonological framework. Planetary seals come from a Neoplatonic astrological framework. Mixing them without understanding the cosmology weakens both.
How to Tell Them Apart at a Glance
There are visual cues that distinguish the two, even when the style is unfamiliar.
Goetia sigils tend to be asymmetrical, with irregular curves, branching lines, and small circles or dots. They often incorporate human or animal features (crowns, heads, wings). They are drawn in a single continuous line, as if tracing a signature. The ink is black, and the parchment is usually unadorned.
Planetary seals are symmetrical, composed of straight lines and arcs, with the planetary glyph at the center or at the top. They are enclosed in a circle, often with the names of angels or divine names written around the rim. The seal of Jupiter, for example, is a four-pointed star with a central dot, surrounded by the Hebrew names of the planetary intelligence.
If you see a symbol that looks like a geometric mandala, it is likely a planetary seal. If you see a symbol that looks like a stylized creature or a tangled line, it is likely a Goetia sigil.
FAQ
Can I use a Goetia sigil for protection? No. Goetia sigils are designed to summon spirits, not to ward them off. Using one as a protective talisman is a common error that can produce unintended results.
Are planetary seals the same as planetary sigils? The terms are often used interchangeably, but “seal” is more precise. A planetary seal is a specific geometric figure derived from the kamea. A planetary sigil can refer to the astrological glyph of the planet itself.
Do I need to consecrate a Goetia sigil? Yes. The sigil must be drawn with intent and consecrated through ritual, typically by placing it in the triangle of art and invoking the spirit. A sigil drawn casually has no power.
Which is older: planetary seals or Goetia sigils? Planetary seals are older. The kamea system dates to at least the 10th century, while the Goetia sigils as a set appear in the 16th century. But both draw on earlier traditions of magical writing.
The distinction between Goetia sigils and planetary seals is not academic. It shapes how you use the symbol. A seal of Jupiter worn as an amulet works by resonance. A sigil of Bael drawn in the triangle works by command. One is a key to a room. The other is a knock on a door.
