A 1510 manuscript shows a young German scholar copying planetary square charts by lamplight. He is not sketching decorative patterns. He is building what he believes is a working model of the universe with seven layers: one for each visible planet, each bearing a mathematical signature. His name is Heinrich Cornelius Agrippa von Nettesheim, and the difference between Agrippa’s planetary and celestial magic is one of scope, hierarchy, and practical operation. Planetary magic works with the seven classical planets and their intelligences. Celestial magic works with the fixed stars and the images (sigils) of their constellations, drawing power from beyond the planetary spheres.
Agrippa did not invent either system. He compiled, systematized, and published them in De Occulta Philosophia Libri Tres (1533). What follows is how he understood them to be different, where they overlap, and why a sixteenth-century magician would choose one over the other.
Where Agrippa Got His Planetary System
The seven-planet framework Agrippa inherited was already old by 1533. Ptolemy’s Tetrabiblos (2nd century CE) had codified the planetary influences for astrology. Marsilio Ficino’s De Vita (1489) had adapted those influences into a medical-magical system for drawing down planetary power. Agrippa took Ficino’s framework, added the Jewish angelic and divine name correspondences from the Sepher Yetzirah and the Zohar, and embedded the whole structure in a Neoplatonic ladder of being.
In Agrippa’s model, each planet rules one “sphere” that the soul passes through on its descent into matter. The Moon is closest to Earth. Saturn is farthest, just below the sphere of the fixed stars. The magician does not move upward through these spheres. He works downward. The planetary magic Agrippa describes is the art of attracting the influence of a given sphere into a material object, a talisman, or a human body.
Each planet has a hierarchy of governors:
- Intelligence (the directing consciousness of the sphere)
- Daemon (the executor of that intelligence)
- Angel (the messenger between sphere and material world)
- Image (the visible form, what we actually see in the sky)
The practical work required the magician to know the planet’s day, hour, corresponding metals, colors, incenses, and the names of its angels. Agrippa provided the Hebrew-letter seals and the numbered squares (now called magic squares) for each planet. A Saturn talisman cut at the correct hour into lead, with the square of three engraved, was not a symbol. It was a battery.
The Celestial Realm: Beyond the Planets
Agrippa called the sphere of the fixed stars the Ogdoadic Heaven (from Greek ogdoas, eight). It sits above the seven planetary spheres. It is the eighth heaven, the realm of the thirty-six decans and the forty-eight Ptolemaic constellations. The planetary spheres are corruptible and subject to change, Agrippa argued. The fixed stars are not. They are eternal, and their influence is more direct, more potent, and harder to control.
Celestial magic in Agrippa’s system works with astral images and sigils derived from the constellations. The most famous source for these images is the Picatrix (the Ghāyat al-Ḥakīm, a 10th-century Arabic grimoire translated into Latin in 1256). Agrippa quoted the Picatrix extensively in Book II of De Occulta Philosophia. He did not invent the images. He copied them, then added his own angelic and Kabbalistic correspondences.
The key difference is practical. Planetary magic requires the magician to match the operation to the planetary hour, the phase of the Moon, and the planet’s condition in the sky. Celestial magic is more absolute. When the fixed star rises above the horizon, its power is present regardless of the Moon’s phase or the hour of the day. The magician who knows how to make a talisman of the Lion’s Heart (Regulus, the brightest star in Leo) can do so at any time Regulus is above the horizon. The planetary magician doing a solar operation must wait for a Sunday at the solar hour in a favorable election.
How You Spoke to Each
The language of address changed between the two spheres.
For planetary spirits, Agrippa prescribed prayers and invocations in Hebrew (or Latin approximations of Hebrew), structured as hymns to the planetary intelligence. These prayers praised the intelligence, offered its sigil, and requested the desired influence. They were formal, structured, and deferential. The magician stood as a petitioner before a higher power.
For celestial spirits and the images of the fixed stars, the tone shifted. Astral images were less spoken to and more activated. The magician cut the image, consecrated it with incense and suffumigation, and placed it. The image itself, correctly made at the correct rising, did the work. The magician was an artisan, not a petitioner.
This is not always clear in Agrippa’s text. He sometimes conflated the two modes. But the practical tradition, as reconstructed from later practitioners such as John Dee and Robert Turner, made this distinction explicit. Dee’s Monas Hieroglyphica (1564) attempted to unify planetary and celestial magic into a single symbol. He failed. The two never fully merged.
What Each System Actually Did
The goals were not the same.
Planetary magic addressed specific, bounded human concerns:
- Saturn: binding, constraint, protection from thieves, long-term projects
- Jupiter: wealth, honor, legal victory, friendship
- Mars: courage, victory, surgical operations, sexual dominance
- Sun: glory, vitality, healing, advancement
- Venus: love, marriage, beauty, fertility
- Mercury: eloquence, trade, divination, trickery
- Moon: journeys, dreams, theft (finding what is hidden), childbirth
Each planet governed a department of life. The magician selected the planet like a man filing a request at a specific office in a vast bureaucracy.
Celestial magic addressed larger, longer-term outcomes. The fixed stars governed nations, eras, dynasties, and world events, not individual love affairs. Agrippa listed the thirty-six decans of the zodiac, each ruling a ten-degree segment of the sky, and assigned to each a set of powers: one decan gave victory in war, another bestowed wisdom, a third conferred wealth. These were not small effects. They were life-defining.
The difference is scale. The planetary magician might ask Venus to bring a lover. The celestial magician might ask the decan of the Lion’s Heart to make him a king.
The Hierarchy Problem
Agrippa faced a theological problem. Christian orthodoxy held that all spirits ranked above the Moon were good (or at least neutral). Spirits below the Moon, in the sublunary sphere, were potentially demonic. Agrippa needed a way to distinguish planetary spirits from celestial spirits from demons without contradicting the Church.
He solved it by ranking the three worlds:
- Elemental world (Earth, water, air, fire) — governed by elemental spirits and angels of the four elements
- Celestial world (the planets and fixed stars) — governed by planetary intelligences and celestial angels
- Intellectual world (the divine realm beyond the stars) — governed by archangels and God directly
This three-world schema appears in Book I (elemental), Book II (celestial), and Book III (intellectual) of De Occulta Philosophia. Planetary magic occupies the upper part of the celestial world, closer to the intellectual world. Fixed-star magic occupies the lower part of the celestial world, bordering the elemental world.
That is why Agrippa warned that celestial images, incorrectly made, could attract demons. The fixed stars are closer to the corruptible world. A mistake in a planetary operation might produce an imperfect result. A mistake in a celestial operation might produce a demon.
Where the Two Systems Overlap
The boundary is not clean. Some operations sit exactly on the seam.
Agrippa’s lunar talismans are a good example. The Moon is the lowest of the planetary spheres, the closest to the Earth, and the most receptive to fixed-star influence. A lunar talisman cut at the hour of the Moon but with the Moon in the degree of a fixed star (say, the Moon in 15 degrees of Virgo, where the star Spica resides) draws on both systems simultaneously. The planetary influence provides the base. The fixed star modifies it.
The image of the Head of the Dragon (the ascending lunar node) also straddles both systems. It is not a planet, not a star, but a mathematical point where the Moon’s orbit crosses the ecliptic. Agrippa gave it planetary treatment because its influence was powerful and fateful. It appears in the list of planetary seals but behaves like a fixed star.
A later magician, Thomas Vaughan (writing as Eugenius Philalethes, 1650), argued that Agrippa had deliberately blurred the two systems to prevent the uninitiated from working celestial magic. There is no evidence for this, but it became a persistent rumor among English occultists.
Common Misconceptions About Agrippa’s Two Magics
“Planetary and celestial magic are the same thing.” They are not. They operate on different spheres, use different materials and methods, and address different scales of effect. Planetary magic is for everyday life. Celestial magic is for life-defining events.
“Celestial magic is more powerful.” It is more direct, but also more dangerous. A fixed-star talisman made at the wrong degree can produce the opposite effect. Agrippa specifically warned against cutting the image of the Lion’s Heart when the Moon was in bad aspect to Mars. The result was not a dead talisman. It was a harmful one.
“Agrippa was an astrologer, not a magician.” Agrippa practiced what he wrote. He was pursued by accusations of sorcery throughout his life. He fled one city after another, leaving manuscript copies of his work behind as debts. His letters to Johannes Trithemius (1510) show a man who had already performed planetary operations and was asking for guidance on the fixed stars.
“The fixed-star images come from Agrippa.” They come from the Picatrix, from Arabic astral magic, from the Hellenistic magical papyri, and from the Hermetic tradition. Agrippa compiled them. He did not invent them.
FAQ
Can you practice planetary magic without learning celestial magic? Yes. Planetary magic is self-contained. Many modern practitioners never go beyond the seven planets. The celestial system is an advanced course.
Which is older, planetary or celestial magic? Celestial magic, by several thousand years. The fixed-star decans appear in Egyptian funerary texts from the Coffin Texts (c. 2000 BCE). Planetary magic as a systematic art is roughly contemporary with Hellenistic astrology (c. 200 BCE).
Do modern occultists like the Golden Dawn use Agrippa’s system? The Hermetic Order of the Golden Dawn (founded 1888) absorbed Agrippa’s planetary system through the works of Francis Barrett and Éliphas Lévi. Their planetary pentacles are directly descended from Agrippa’s woodcuts.
What is the single best source for Agrippa’s system? The English translation of Three Books of Occult Philosophy by James Freake (1651), reprinted by Llewellyn and edited by Donald Tyson. It contains all three books, the planetary squares, the celestial images, and the angelic names.
