A medieval magician copying a grimoire by candlelight misread a single Hebrew letter. That mistake, repeated across centuries, is why the Seal of Saturn and the Seal of Satan still get swapped in online forums and occult shops today. The Seal of Saturn is a planetary symbol from the Key of Solomon, used for binding and limitation. The Seal of Satan is a much later invention, appearing in the 19th century French grimoire The Grand Grimoire, and serves a completely different function in ceremonial magic.
The two seals share visual DNA: concentric circles, angular characters, and a reputation for “dark” work. But they belong to different magical systems, different centuries, and different intentions. One constrains. The other commands. Confusing them is not a minor error. It is the difference between locking a door and opening one you cannot close.
What Each Seal Actually Is
The Seal of Saturn appears in the Key of Solomon (Clavicula Salomonis), a grimoire compiled in the 14th and 15th centuries from earlier Jewish mystical sources. Saturn is the slowest planet, the outermost sphere, the boundary of the known cosmos. In medieval astrology, Saturn governed limitation, time, death, and the hard lessons that come with age. The seal was not a demonic sigil. It was a tool for binding: binding spirits, binding harmful influences, binding the magician’s own impulses.
The Seal of Satan appears in Le Grand Grimoire (also called The Red Dragon), a French text from the early 18th century. This grimoire claims to contain the secrets of summoning Lucifer and his lieutenants. The seal is a pact signature. The magician draws it on parchment, signs it in blood, and buries it at a crossroads to formalize a contract with infernal powers. It is a signature, not a circle of protection.
The visual similarity is not accidental. The Grand Grimoire borrowed heavily from the Key of Solomon tradition, copying its diagrammatic style but replacing planetary angels with demons. The concentric circles remained. The content changed.
Where the Confusion Began
The first documented confusion appears in the work of A.E. Waite, the 19th century occultist who translated and compiled several grimoires for the Hermetic Order of the Golden Dawn. In his 1898 Book of Black Magic and of Pacts, Waite grouped the planetary seals of the Key of Solomon alongside the infernal seals of the Grand Grimoire under the same chapter heading. He was documenting, not endorsing, but the damage was done. Readers saw Saturn and Satan on the same page and assumed a connection.
The confusion deepened in the 1970s when the New Age publishing boom reprinted both grimoires in cheap paperback editions. Illustrators, working from photocopies of photocopies, simplified the seals. The Seal of Saturn lost its Hebrew characters. The Seal of Satan gained new geometric flourishes. By the 1990s, internet forums were circulating images labeled “Seal of Satan” that were actually the Seal of Saturn rotated 90 degrees.
We have watched practitioners arrive at our library holding a printout of the wrong seal, convinced it was the right one, because the image had been shared and reshared so many times that its origin was lost. The fire is not decoration. It is the altar. The seal is not decoration either. It is the lock or the key, and using the wrong one changes everything.
The Seal of Saturn: Design and Function
The Seal of Saturn from the Key of Solomon consists of a six-pointed star (hexagram) inscribed within a double circle. Between the two circles, Hebrew letters spell out divine names associated with Saturn: Yod-He-Vav-He (the Tetragrammaton) and Elohim, among others. The hexagram itself contains smaller geometric figures and additional Hebrew characters.
The seal was drawn on a sheet of virgin parchment, never on paper, and consecrated with the smoke of frankincense and myrrh. The magician recited Psalm 91 while tracing the lines. The finished seal was placed inside a triangle of art, the protective space from which spirits were summoned and commanded.
Saturn’s planetary hour was chosen for the work: Saturday, at the hour of Saturn, when the planet was visible in the sky. The seal was not worn as an amulet. It was placed on the altar or held in the magician’s left hand during the ritual. Its purpose was to compel obedience from spirits that resisted the magician’s authority.
The Key of Solomon gives explicit instructions for each planetary seal. Saturn’s seal binds spirits of Saturn, which include the angel Cassiel and the demonic spirit Oriens (one of the four cardinal demons). The seal does not summon them. It forces them to obey commands already given.
The Seal of Satan: Design and Function
The Seal of Satan from Le Grand Grimoire is simpler. A single circle encloses a five-pointed star (pentagram) with Hebrew or pseudo-Hebrew characters in the outer ring. The central space is left blank for the magician’s signature in blood. The text specifies that the seal must be drawn on the skin of a lamb or a goat that has never been shorn, using a pen made from a raven’s feather and ink mixed with the magician’s own blood.
The ritual is stark. The magician draws the seal at midnight on a Tuesday or Saturday during a waning moon. The seal is then wrapped in a black cloth and buried at a crossroads, with the magician’s left foot placed on the burial spot while reciting the conjuration from the grimoire. The demon is expected to appear within 24 hours.
Unlike the Seal of Saturn, which is a tool of control, the Seal of Satan is a tool of negotiation. The magician offers something in exchange for power: a drop of blood, a signature, a promise. The seal is the contract. The Grand Grimoire warns that the magician must never break the terms, or the seal will turn against them.
The grimoire itself is attributed to “Antonio Venitiana del Rabina,” a pseudonym that scholars have never identified. The earliest surviving copy dates to 1702, printed in Paris. The text claims to have been dictated by Lucifer himself, a claim that no serious historian accepts but that gives the seal its enduring mystique.
How You Spoke to Each
The Seal of Saturn was spoken to in Hebrew. The magician addressed the spirit by its divine name, not its personal name. The language was formal, liturgical, borrowed from the synagogue. The seal was a piece of writing that the spirit was forced to read and obey.
The Seal of Satan was spoken to in French or Latin, depending on the edition. The magician addressed the demon by name: Lucifer, Beelzebub, Astaroth. The language was imperative, demanding, personal. The seal was a signature that the demon recognized as binding.
One seal works through the authority of God. The other works through the authority of the magician’s own blood. They are not the same magic. They are not even the same century.
Symbolism and Meaning
Saturn’s seal carries the weight of limitation. The hexagram represents the union of spirit and matter, but in Saturn’s context it is a cage. The six points correspond to the six days of creation, with Saturn as the seventh day of rest and restriction. The Hebrew letters spell names that mean “God of Hosts” and “The Lord.” The seal is a prison built from the names of God.
Satan’s seal carries the weight of rebellion. The pentagram represents the human form, the five senses, the material world. In the Grand Grimoire, the pentagram is inverted, with one point downward and two points upward, though the original woodcut is ambiguous. The blank center is the magician’s own absence, filled by the signature that makes the contract real. The seal is a door built from the magician’s own substance.
The difference in geometry matters. The hexagram is stable, symmetrical, closed. The pentagram is open, dynamic, capable of inversion. Saturn’s seal contains. Satan’s seal releases.
Common Misconceptions
Misconception: The Seal of Saturn is demonic. It is not. Saturn is a planet, not a demon. The seal binds spirits, including demonic ones, but it is a tool of the magician, not a symbol of allegiance. Medieval grimoires treat planetary spirits as neutral forces that can be compelled for good or ill depending on the operator’s intent.
Misconception: The Seal of Satan is from the Key of Solomon. It is not. The Key of Solomon contains no seals for Satan, Lucifer, or any infernal hierarchy. Its spirits are planetary, elemental, and zodiacal. The Grand Grimoire is a separate text with a different cosmology.
Misconception: The seals are interchangeable. They are not. Using the Seal of Saturn in a pact ritual will produce no result, because the seal is designed to bind, not to contract. Using the Seal of Satan in a binding ritual will produce no result, because the seal is designed to open, not to close.
Misconception: The seals are evil. Neither seal is inherently evil. Saturn’s seal was used for protection and limitation. Satan’s seal was used for pacts, which the Church condemned but which practitioners viewed as transactions. The morality depends on the user, not the symbol.
FAQ
Can the Seal of Saturn be used for protection? Yes. In the Key of Solomon, the Seal of Saturn is specifically recommended for binding harmful spirits and protecting the magician during evocation. It is one of the most powerful protective seals in the planetary tradition.
Is the Seal of Satan the same as the Sigil of Lucifer? No. The Sigil of Lucifer is a different symbol, appearing in the Grimorium Verum and other 18th century texts. The Seal of Satan from Le Grand Grimoire is a specific diagram with its own ritual context.
Which seal is more dangerous? Neither seal is dangerous by itself. A seal is a tool. The danger comes from the ritual context and the practitioner’s skill. An unprepared magician using either seal without proper consecration and protection is more likely to harm themselves than to summon anything.
Can I draw these seals today? You can, but the traditional materials matter. Saturn’s seal requires virgin parchment and consecrated ink. Satan’s seal requires animal skin and blood. Modern practitioners often adapt these requirements, but the original texts are explicit about the consequences of substitution.
Related Guides
The planetary seals of the Key of Solomon form a complete system of seven symbols, one for each classical planet. Understanding Saturn’s seal requires understanding its place in that system. The Grand Grimoire belongs to a different tradition entirely, one that draws on the Key of Solomon but reinterprets its symbols for infernal work.
For a deeper look at how planetary magic works across traditions, see our planetary magic guide. For the specific symbols and their variations across grimoires, the glossary of seals provides visual comparisons. And for the full ritual context of the Seal of Saturn, the Key of Solomon guide covers the consecration, timing, and planetary hours that make the seal effective.
The seals are not interchangeable. They are not enemies. They are two different tools from two different workshops, and the first step to using either one is knowing which one you are holding.
