Since humanity first looked up at the sky, the stars have been much more than points of light in the night. For sages since time immemorial, each planet was the seat of a living power, endowed with its own will and character. These entities, called planetary spirits, were invoked, honored, and sometimes feared, in the hope of gaining their favor, for they alone govern the forces of the universe. Explanation.
Planetary spirits across traditions
Since Antiquity, the seven wandering stars – Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon – have been associated with spiritual or divine entities that govern them. In ancient Greco-Egyptian and Gnostic traditions, these planetary spirits appear as cosmic powers ruling fate and obstructing the soul's ascent. The Ophite Gnostics (a branch of the Gnostic movement that gave a central place to the serpent from the biblical Genesis story) identified each planet with an archon: Saturn was dominated by Ialdabaoth, the Demiurge “with a lion's face,” Jupiter by Iao, Mars by Sabaoth, the Sun by Adonaïos, Venus by Astaphaïos, Mercury by Elaios, and the Moon by Horaios. These names, derived from Hebrew terms for God, reflect this esoteric vision where planets are inhabited by spirits sometimes benevolent, sometimes hostile.
In the Hermetic and Neoplatonic tradition, it is also considered that each planetary sphere is animated by a celestial intelligence emanating from the Divinity, and sometimes by a lower genius (spirit) more earthly. The Renaissance mage Cornelius Agrippa thus explains that for each planet God established “an Intelligence for good and a spirit for evil”. These entities serve as mediators between the divine world and the material world. In the medieval and Renaissance periods, under the influence of Arabic astrology and Hermetic texts translated from Greek or Arabic, the idea of summoning planetary geniuses through magical rituals developed. Treatises like the Picatrix (Ghâyat al-Hakîm) or the Liber Juratus teach the making of talismans and the invocation of planetary spirits to obtain concrete effects (wisdom, love, wealth, protection,...) in accordance with astrological correspondences. Traditional rituals provided to work “on the day and at the hour” of the concerned planet, using incense, prayers, and other appropriate “suffumigations,” sometimes offerings or fasts, in order to attract the influence of the targeted planetary genius.
Saturn, the lord of time and its Genius
Symbol of time, slowness, and melancholy, Saturn has always fascinated with its dual face of great astrological malefic and master of contemplation. In Greco-Roman mythology, it is Cronos/Saturn, the old god of time who devours his children. Ancient esoteric currents made it a formidable power: in Gnostic cosmology, the planetary genius of Saturn is Ialdabaoth, the proud Demiurge creator of the material world, assimilated to Satan. Conversely, Neoplatonic philosophers saw the star Saturn as the highest sphere before the fixed stars, associated with Supreme Intelligence and contemplative wisdom.

In medieval and Renaissance magic, Saturn is served by several emblematic entities. The Kabbalistic and angelic tradition names Cassiel (or Tzaphqiel) as the archangel ruler of Saturn. Cassiel is described as a stern angel, associated with temperance and solitude, who observes worldly affairs without much intervention. Meanwhile, Agrippa attributes to Saturn the beneficial intelligence Agiel and the adverse spirit Zazel, derived from Hebrew names and associated with the number 45, the mystical total of Saturn’s magic square. Zazel is considered in some grimoires as a demon of Saturn, bearer of harmful influences (curses, obstacles), while Agiel would be the entity to invoke for constructive Saturnian works (knowledge of hidden things, inner discipline).
One of the most notable planetary spirits of Saturn is Aratron, presented in the Arbatel as the “Olympic governor” of Saturn. Aratron commands 49 provinces of the cosmos and must be invoked on Saturday at the first hour of the day (Saturn’s hour). According to the Arbatel, Aratron presides over everything astrologically attributed to Saturn: “He can turn any living being into stone in an instant; change coal into treasure and vice versa; he gives familiar spirits and reconciles underground spirits with men; he teaches alchemy, magic, and medicine.” He can also make one invisible, cause sterile people to have children, and “grants a long life” to the mage who gains his favor. Aratron thus appears as a powerful spirit of transmutation and occult knowledge – reflecting Saturn’s qualities of slow transformation, hidden wealth underground (metals, treasures), and mastery of time.
Historically, Saturn invocations were reputed to be difficult and dangerous due to the cold, dry, and restrictive nature of this planet. Rituals advised acting within a favorable astrological framework (Saturn in a good position), otherwise the genius could manifest its harmful side. In talismanic magic, a Saturn talisman engraved on lead under good auspices served to ensure protection and power – but under harmful influences, the same inscriptions could instead cause ruin, discord, and delays. A text by Agrippa indeed states that if made when Saturn is “unfortunate,” a Saturn talisman “prevents constructions, causes loss of honors and dignities, causes discord and quarrels”. For caution, practitioners sought to invoke the “exalted” Saturn (the archangel or benevolent intelligence) to gain favor from high-ranking people, stability, and depth of mind, while protecting themselves from the “dark” Saturn (the demon Ialdabaoth or Zazel) who brings sadness and obstacles. This duality well illustrates the rich symbolism of Saturn: both master of secret knowledge and hidden riches, and bearer of trials and severe lessons.
Jupiter, the celestial king and his blessings
Jupiter, the brightest planet after Venus, has traditionally been associated with benevolence, royalty, and prosperity. Among the Greeks and Romans, he corresponds to Zeus/Jupiter, father of the gods, guarantor of cosmic order, justice, and abundance. In ancient astrology, Jupiter is the “Great Benefic” bringing expansion and fortune. Esotericists have therefore seen in its genius a positive tutelary force, almost angelic.
In the Judeo-Christian celestial hierarchy, the archangel of Jupiter is called Sachiel (or Zadkiel). His name means “Justice of God” or “Grace of God,” and he appears in grimoires such as the Heptameron (16th century) among the governing angels of Thursday, the day of Jupiter. Sachiel/Zadkiel is associated with mercy, generosity, and spiritual wealth, qualities reflecting the Jovian influence. In the Kabbalah, Jupiter corresponds to the sephira of Hessed (Grace), and Zadkiel is the angel of divine benevolence, presiding over clemency and prosperity.

Renaissance occultists also mention an intelligence of Jupiter named Johphiel (or Jophiel) and a lesser spirit Hismael, according to Agrippa’s magic squares. Agrippa indicates that the total number associated with Jupiter is 136, and that “Yohphiel, Intelligence of Jupiter” and “Hismael, Genius of Jupiter” derive numerically from it. These Hebrew-origin names (containing the suffix -el, “of God”) show that Jupiter was integrated into an angelic cosmology: Yohphiel representing the planet’s luminous and beneficial power, and Hismael its more material energy to be mastered.
In the context of planetary magic, the Olympic genius attributed to Jupiter is Bethor. The Arbatel describes Bethor as the jovial spirit quick to respond to requests: “The affairs of Jupiter are administered by Bethor, who responds quickly when called”. Anyone acting under his character (his seal) “can be elevated to illustrious dignities and obtain vast treasures”. Bethor “reconciles the Spirits of the Air with men, so that they give truthful answers”, transports precious stones where needed, and composes remedies with miraculous effects. He can grant familiars (servant spirits) from the firmament and extend human life up to 700 years if God permits. The occult encyclopedia specifies that Bethor, jovial angel, can be invoked on Thursday in the first hour of Jupiter and that he governs 42 celestial provinces.
Historically, practices aimed at Jupiter sought to capture its beneficial influences of growth and luck. Talismans of Jupiter were made by engraving its seal and numbers on a silver plate on a Thursday when Jupiter was astrologically “worthy” (in good aspect and position). Agrippa states that such a talisman, “Jupiter being powerful and reigning”, brings gain, wealth, favor and love, peace and harmony, and soothes enemies”. Similarly, a prayer invoking the angel of Jupiter could be made to obtain the goodwill of a prince or the success of an enterprise. The texts also contain defensive uses: wearing a Jupiter talisman engraved on coral breaks evil enchantments. The planet of justice was used to dissolve charms and injustices.
The genius Jupiter inspired many occult legends. It was said that the medieval mage Albert the Great had created an oracular bronze head through the combined influences of Jupiter and Mercury – although this anecdote may be mythical. More concretely, Marsilio Ficino in the 15th century recommended singing hymns in honor of Jupiter (such as the Orphic Hymn to Zeus) on Thursdays to attract his gifts of wisdom, optimism, and good fortune to the practitioner's soul. Thus, from late Antiquity to the Renaissance, the Jovian genius was always invoked as a force of grace and expansion, guarantor of balance and prosperity, whether in the material or spiritual realm.
Mars, the celestial warrior and the Genius of strength
Astrologically, Mars is the planet of action, war, and passionate ardor. Identified with the Roman god of war (Ares among the Greeks), it represents combative energy, anger but also courage and willpower. In esoteric cosmology, Mars is considered a more ambivalent influence: necessary to conquer and protect oneself, but potentially destructive if poorly controlled. Its planetary genius reflects this fiery nature.
In the angelic tradition, the archangel associated with Mars is sometimes named Samaël or Camaël. Samaël, whose name means “venom of God,” appears in some Jewish sources as the angel governing the sphere of Mars. The Sabians of Harran (an astral sect of late Antiquity) called him Mara Samîa, and this idea passed down to medieval grimoires. However, Samaël is an ambiguous figure: both angel of judgment and celestial accuser, often equated with a demon in rabbinic literature. In Christian magic, Camaël (“He who sees God”), a warrior archangel leading the powers, is sometimes preferred to embody the positive martial principle. In any case, Mars is linked to the sephira of Guevoura (Severity) in Kabbalah, the domain of divine strength and rigor.

In Agrippa's lists, Mars has as intelligence Graphiel and as genius (spirit) Barzabel. Barzabel (or Barzakhiel in other manuscripts) is seen as a formidable spirit, sometimes classified among demons. His name carries a harsh sound evoking iron and war, in line with the Martian nature. Magic manuals advised approaching him with caution during martial conjurations, as he could just as well grant victory as provoke discord.
The Olympic governor of Mars is named Phaleg, according to the Arbatel. Phaleg is presented more soberly than other spirits: “Phaleg governs what is attributed to Mars. The person who has his character (sign) will be raised by him to great honors in military affairs”. In other words, Phaleg grants success and prestige to the warrior—he was called upon to win battles and duels, obtain bravery, or advance in the military hierarchy. The texts specify that Phaleg rules 35 provinces of the cosmos and must be invoked on a Tuesday (Mars’ day) at the Martian hour, while wearing his seal of command. His assistance was sought not only by soldiers but also by all who needed to assert power or decisively overcome obstacles.
Mars talismans and operations were intended for offensive or protective purposes. A Martian talisman engraved on iron or steel, made when Mars was favorable, had the reputation of making “a man powerful in war and formidable to his enemies, victorious against them”. Conversely, if the same talisman was made under an ill-aspected Mars, Agrippa warned that it “causes disputes, enmities, and hatred between men and beasts, drives away bees, scatters pigeons, prevents mills from working properly, causes sterility and terror”. This shows that manipulating Mars’ energy could easily backfire into curses if one was not careful.
A famous case of using the genius of Mars is recounted in some medieval chronicles: during a siege, a mage supposedly tried to invoke the spirit of Mars to trigger panic and discord among the besiegers—a kind of occult “psychological warfare.” More positively, Martian influences were believed to have the ability to heal certain blood-related diseases or stop hemorrhages (Mars governing iron and blood, a talisman engraved on a carnelian stone was said to “stop blood and menstrual flows”). Furthermore, for personal protection, knights sometimes carried inscriptions of the angel of Mars or recited the Tuesday psalm, hoping to channel warrior courage without cruelty.
Thus, the planetary genius of Mars embodies raw strength and combative will. Whether called Phaleg in a theurgic context or Barzabel in a goetic context, it represents the energy of iron that the mage must forge with caution. In good hands (those of a moral and prepared mage), the power of Mars brings just victory and active protection; in bad hands, it unleashes violence and uncontrolled destruction. This is why rituals emphasize the need for self-control and the legitimacy of the cause when invoking the formidable genius of the red planet.
The Sun, light of the world and Genius of splendor
Day star, center of the traditional planetary system, the Sun has always been considered the source of life, light, and spiritual illumination. In late Antiquity, Hermetic philosophers saw in Helios the symbol of the Nous (the Divine Intellect) that enlightens the soul. Emperor Julian in his Hymn to King Helios sang the Sun as the benevolent demiurge and the heart of the universe. Likewise, in Kabbalah, the Sun corresponds to the sephira Tiphereth, at the center of the Tree of Life, associated with beauty, harmony, and mediation between heaven and earth.
Representation of the Genius of the Sun according to Agrippa. Artist
The solar planetary genius is therefore surrounded by a particular prestige. In the Judeo-Christian tradition, it is associated with Mikhaël (Saint Michael the Archangel), presented as the highest of the archangels and conqueror of dark forces. Michael is often linked to the Sun and solar fire by analogy: leader of the heavenly armies, he shines with divine light and fights darkness as the sun dispels obscurity. Many grimoires (such as the Key of Solomon or Barrett’s Magus) list Michael as the angel of Sunday, bearing the omnipotence of the Sun. Other sources associate the archangel Raphaël with the Sun (notably in the Kabbalistic planets/sephiroth association where Raphaël governs Tiphereth) and Michael with Mercury – there were some variations depending on the esoteric schools. In any case, the Sun is generally under the aegis of a first-rank archangel supposed to bestow illumination, health, and glory.
In magical treatises, there is still a division between intelligence/spirit for the Sun: Agrippa attributes to the Sun the intelligence Nachiel (or Nikhiel) and the lesser genius Sorath. The latter name, Sorath, has intrigued more than one commentator because its numerical values add up to 666 – the famous "number of the Beast" from the Apocalypse. In reality, it is the total number of the solar magic square (6×6 squares giving the sum 666), from which this name is derived. Sorath represents the fiery spirit of the Sun, potentially corrosive or destructive if not controlled, while Nachiel embodies the benevolent solar intelligence granting vitality and success. This duality reminds us that the Sun can burn as much as it illuminates.
The Olympic genius of the Sun, according to the Arbatel, is named Och. Och is described as an extremely powerful spirit, master of wealth and healing: “Solar interests are administered by Och, who extends life up to six hundred years in perfect health. He grants great wisdom, gives excellent familiar spirits, composes perfect remedies, converts any substance into the purest metal or precious stones; he also grants gold and a purse always filled with gold… He ensures that the holder of his character is worshiped as a god by kings worldwide.” As you can see, Och combines miraculous powers: life extension, alchemical transmutation into gold, complete healing, inexhaustible wealth, and even near-divine glory. Of all planetary geniuses, Och is probably the one with the most impressive list of faculties, reflecting the central status of the Sun. The Arbatel also specifies that Och must be invoked on Sunday at the hour of the Sun, as is fitting, and that he will respond favorably to requests as long as they remain within the order willed by God.
Historically, invoking solar influences was prized for everything related to vitality, social success, and spiritual elevation. Marsilio Ficino advised his melancholic disciples to turn toward the Sun: through music, solar hymn singing, and exposure to light, one could balance mood and attract the life-giving influx of Sol. Practitioners made solar talismans in gold (the quintessential solar metal) or by engraving solar symbols on carnelian or ruby to promote healing of diseases and gain honors and joy. An astrologically “worthy” solar talisman was said to “make a man loved by kings and the people, and ensure victory in all things”, so much is the solar aura associated with triumph and magnanimity.
The Sun also played a central role in theurgies: priest-mages recited the Hymn to Helios or used mirrors to capture a sunbeam during certain ceremonies, symbolizing divine illumination descending upon the magic circle. It was believed that the genius of the Sun could reveal the highest mysteries – for example, the Neoplatonic esotericist Iamblichus mentions a “vision of the god Helios” granted to the mage in a state of ecstasy, that is, a communion with solar intelligence. In a more down-to-earth context, medieval astrologer-physicians chose the hour of the Sun to administer certain remedies (related to the heart, sight, or potable gold) to benefit from its healing virtue.
Venus, the lady of love and her Genius of grace
Universal symbol of beauty, love, and fertility, Venus has inspired cults and magical practices since the dawn of civilizations. Identified with the Greek goddess Aphrodite or the Babylonian Ishtar, Venus is the Morning Star who presides over earthly attractions as well as celestial harmonies. Her planetary genius is therefore associated with the power of attraction, grace, and the arts.
In the angelic and Kabbalistic hierarchy, the archangel governing Venus is generally Haniel (or Anaël). Haniel means “Grace of God” – an appropriate name for the angel of the sephira Netzach (Victory), which corresponds to Venus and embodies divine love, beauty, and the victory of life forces. He is depicted as a radiant angel bringing joy, seduction, and artistic creativity. Occult literature ranks him among the seven planetary archangels, ruler of Friday and dispenser of beneficial Venusian influences. In the Sigillum Dei dear to John Dee, the name Anaël appears in correspondence with Venus. Some astrological magic grimoires, following the influence of the Sefer Raziel, also mention an angel called Hagiel or Anael for Venus, alongside a less benevolent spirit Kedemel (or Kedemel) – these names notably appear in Agrippa’s tables of correspondence. Indeed, Agrippa indicates for Venus an intelligence named Hagiel and a “malignant” genius named Kedemel, associated with the number 175 of Venus’s square.

The Olympic genius of Venus, according to the Arbatel, is called Hagith. Hagith is described as the ruler of “Venusian things” (everything related to Venus). Anyone who bears the character (seal) of Hagith “will be adorned with all beauty”. Hagith has the power to “instantly convert copper into gold and gold into copper”, and he “gives faithful servants” to assist the mage. These attributes reflect the subtle alchemy of Venus: beauty (copper, Venus’s metal, can become gold, a symbol of solar perfection, and vice versa – thus Venus mediates between the material and the spiritual), the grace surrounding the loved one, and loyalty in love or friendship (the “faithful servants” can also be understood as the loyalty of companions). The Arbatel specifies that Hagith governs 21 celestial provinces and can be called on a Friday at Venus’s hour to benefit from his gifts.
Love and artistic magic throughout history have abundantly claimed Venus. Recipes for love potions, rituals to attract a partner or rekindle a spouse’s affection called upon the evening star. The Picatrix gives instructions to carve the image of a man and woman entwined on a Friday under a favorable Venus conjunction, fumigating with sweet perfumes (sandalwood, rose) to invoke the Venusian spirit who “unites hearts.” Likewise, it was advised to carry copper engraved with Venus’s signs (since its number 7 and its seal were often traced there) to increase one’s charm and popularity.
A notable use, reported by medieval texts, is the invocation of the angel Anael on Friday before sunrise to consecrate magic mirrors intended for love. Prayers were recited so that Anael would grant the mirror the power to reflect the image of the soulmate or to reconcile separated lovers. Renaissance astrologers’ journals also show that Venus was invoked to promote fertility: to help a couple conceive a child, a Venus talisman was calculated on a fig leaf, which, placed under the bridal bed, was meant to inspire harmony and fertility from the Venusian spirit.
Of course, Venusian spirits could also be diverted for less noble purposes – there are records of attempts at lust or forced seduction spells by calling upon the demons of Venus. Tradition even makes Asmodeus (Asmodai) a demon of lust once associated with Venus in certain classifications. However, in the serious sources we prioritize, the emphasis is on the positive celestial Venus, patron of sincere love and inspired art. Paracelsus considered the Venusian imprint essential in spagyric medicine for preparing remedies acting on the renal and reproductive organs. He spoke of the “fire of Venus” as a moderate, restorative vital heat, in contrast to the more violent “fire of Mars.”
The planetary genius of Venus, whether under the name Hagith, Haniel, or Anaël, embodies the force of attraction that binds the Universe. Its traditional invocation aimed to increase beauty, love, and harmony. The ancients said that Venus “softens manners” – indeed, in a well-conducted ritual, the mage had to surround themselves with music, songs, sweet perfumes, create a harmonious and joyful atmosphere to invite the Venusian genius. For it is through joy, grace, and pure affectionate intention that one touches the heart of this powerful spirit of cosmic love.
Mercury, the winged messenger and the Genius of knowledge
Mercury, a fast and elusive planet, has always been associated with the principle of movement, exchange, and intelligence. It is Hermes for the Greeks, Thoth for the Egyptians – the messenger of the gods, master of words, roads, and occult sciences. The planetary genius of Mercury is thus linked to knowledge, communication, and also, sometimes, to cunning or even ambiguity (Mercury can be deceptive).
In the Western Kabbalistic and angelic tradition, Mercury is placed under the aegis of Raphael, archangel of Medicine and Science. Raphael, whose name means “God heals,” is one of the seven archangels and is said to rule over Wednesday and the planet Mercury in many planetary magic grimoires. Other lists attribute Mercury to Mikhaël (this was the case in some correspondences of the Liber Juratus), which can be confusing – but most Renaissance occultists followed the scheme: Raphael for Mercury, Michael for the Sun. In any case, the mercurial spirit is seen as fundamentally luminous and airy, bearer of intellect. In Kabbalah, Mercury corresponds to the sephira Hod (Glory), domain of reason, language, and ritual magic – Raphael or Mikhaël are its guardian angels depending on the sources.

Faithfully, Agrippa endows Mercury with an intelligence named Tiriel and a lesser genius called Taphthartharat. The latter name, with its repetitive consonants, was reputedly difficult to pronounce – some saw it as a mnemonic device to trace the genius’s sigil on Mercury’s square (8x8 cells, sum 2080). Taphthartharat is described as an unstable spirit, like quicksilver (metallic mercury) that constantly changes form. In contrast, Tiriel represents the fixity of Mercurian intelligence capable of extracting order from chaos. Again, we find the idea of a dual aspect: Mercury can enlighten the mind (sudden intuition, eureka!) or mislead into illusions (deceit, sophistry), and the mage must therefore address Tiriel/the archangel Raphael for constructive results, while being wary of the cosmic trickster that is Taphthartharat.
The Olympic genius of Mercury is called Ophiel in the Arbatel. Ophiel is presented as the master of Mercurian things, dispensing knowledge and talents. The Arbatel states: "Ophiel is the governor of what is attributed to Mercury; he gives familiar spirits, teaches all arts, and allows the one who possesses his character to instantly change quicksilver into the philosopher's stone." This passage is rich in meaning: Ophiel easily grants familiars (servant spirits able to assist in intellectual or magical work), he teaches all arts (thus conferring inspiration and technical knowledge, whether in astrology, eloquence, or mathematics), and he holds the secret of the ultimate transmutation – vulgar Mercury (quicksilver) being fixed into the philosopher's stone. This last ability places Ophiel at the heart of spiritual alchemy: Mercury is indeed, for alchemists, the volatile principle to be transmuted. Ophiel, invoked on a Wednesday at Mercury’s hour, could according to legend reveal the recipe for the philosopher's stone or at least guide the alchemist on their path.
Invocations of Mercury throughout history have served various purposes: acquiring eloquence (for example, Roman orators worshipped Mercury to speak well in the forum), excelling in the sciences (many Renaissance scholars – Gérard Dorn, Tycho Brahe – wore Mercury talismans to stimulate their intellect), or traveling safely (Mercury being the patron of travelers and merchants, his seal was believed to protect during journeys). A traditional Mercurian talisman was made by engraving a symbol of Mercury on an emerald or an agate, said to bring quick memory and sharp wit to the wearer. Manuals also recommend using mastic or lavender incense for Mercurian fumigations, as these scents stimulate the mind without overexciting it.
A notable example is that of Dr. John Dee, an Elizabethan occultist, who mentions in his notebooks having invoked the “Angels of Mercury” multiple times to better understand the structure of the universe. Dee worked to decipher the angelic language and believed that Mercury – the planet of intellect – held the key to the sacred Word. In his scrying sessions with Edward Kelley, he hoped to obtain from Uriel or Raphael (linked to Mercury) the letters of the Enochian. Thus, Mercury is seen as the planet of ceremonial magic itself: it is through its genius that rituals are organized (Hod being the sphere of ritual magic in the Kabbalistic tree).
It should be noted, however, that Mercury was also invoked for more worldly tricks: highway robbers sometimes prayed to Mercury (as the Roman god of thieves) to grant them luck and cunning! Defensive magic texts suggest calling on Mercury to confuse a liar or thwart an unfair contract, reflecting the “trickster” aspect of the planet. Nevertheless, in serious esoteric literature, Mercury remains above all the genius of the Logos, that is, the ordering intelligence of the world. It is he who constantly connects the celestial domain and the earthly domain through the thread of reason and language. Invoking Mercury is seeking to understand, to translate the invisible into the visible – a quest dear to mages and philosophers of all times.
The Moon, guardian of dreams and Genius of mysterious flows
The Moon, Earth's only satellite, holds a unique place in esoteric cosmology: it is at the boundary between the sky and the sublunar world, mediator of the influences of the stars toward our world. Changing, reflecting the light of the Sun, it has always been associated with the world of dreams, imagination, waters, and biological cycles (especially feminine ones). The lunar planetary genius is therefore linked to the magic of illusions, nocturnal revelations, and natural growth.
In the classical angelic hierarchy, the archangel of the Moon is Gabriel, the Messenger of God, announcer and guide of souls. Gabriel governs Monday and the sphere of the Moon in the Heptameron and other grimoires; he is invoked for everything related to messages, fertility, and the protection of night journeys. Kabbalah associates the Moon with the sephira Yesod (the Foundation), reservoir of astral forces, and Gabriel reigns there as the provider of cosmic influences to Earth. Gabriel being the angel of the Annunciation aligns with the idea that the Moon transmits the “announcements” of the cosmos (astral influxes) into the sublunar world.
Representation of the Moon Genius according to Agrippa. Artist
Agrippa attributes to the Moon a multitude of complex names drawn from the Hebrew tradition. He mentions a genius named Hasmodai for the Moon – which is nothing other than a transliteration of Asmodeus, a well-known demon, here considered an evil lunar spirit (perhaps because the Moon governs fantasies and lust, of which Asmodeus is the demon). By contrast, the aggregate of benevolent lunar angels is called Malcha betharsithim hed beruah schehakim in some versions, which essentially means “King of the stars and heavens” – a grand title for the intelligence of the Moon. These rare names highlight the richness of the lunar tradition, where angels, demons, and nature spirits mingle.
The Olympic genius of the Moon, in the Arbatel, is named Phul. Phul is presented as the governor of “lunar things” and a friend of transformation. The text says of Phul that “he changes all metals into silver by word and deed; he governs lunar things, cures dropsy, and provides water spirits (Undines) who serve man in a corporeal and visible form; moreover, he makes [man] live 300 years”. Thus, Phul has the power of transmutation (into silver, the metal of the Moon), healing of water-related diseases (dropsy, excess fluids), and commands elemental water spirits (Undines or fountain spirits) by making them visible and useful to the operator. Finally, he can extend life, though less than higher geniuses (300 years versus 600 for Och). The Arbatel advises invoking him on Monday, which is obvious, and praises the relative simplicity of his invocation for those who respect the rituals. Phul is therefore a genius linked to water and moon magic, touching on the mysteries of fluidity, healing through fluids, and the appearance of spirits.
In historical magical practice, the Moon was heavily used for divination and spiritual journeys. Onomancy (divination through dreams) recommended praying to the Moon and Gabriel before sleeping to obtain clear prophetic dreams. Likewise, “magic mirrors” or water basins for catoptromancy (divination by mirror) were traditionally prepared during the hour of the Moon, so that the lunar genius would reflect visions there. A medieval tale recounts that a mage of King Henry III of England once, on a full moon night, summoned the angel Gabriel in a silver basin to show the king the image of the future queen – a probably legendary process, but one that illustrates the belief in the visionary power of the lunar genius.
The Moon was also crucial for agricultural magic: peasants planned sowing and harvesting according to it, and some rituals to promote plant growth invoked the “lady Moon” to water the fields with her beneficial dew. A small 15th-century agricultural grimoire advises, for example, to hang a lead talisman marked with the lunar sign in the orchard at the New Moon, while whispering a prayer to Phul, to ward off harmful insects and ensure a juicy harvest.
Let us not forget the more occult aspect: the Moon governing changeable spirits, it was invoked for transformations and enchantments. Witches in legends call upon the Moon to transform themselves (hence the werewolf myth linked to full moons). In learned ritual magic, there are recipes to become invisible using the illusory power of the Moon – the Book of Honorius offers a charm to be performed on a Monday night, burning camphor and salt (lunar substances), so that “men’s eyes see you as transparent.” Here, the genius of the Moon is summoned to plunge others into illusion.
However, warnings were given against lunar deceptions: the Moon reflects and distorts, it is unstable. Practitioners had to purify their intentions, as poorly framed magical work during an unfavorable lunar phase could lead to madness, hallucinations, or errors in judgment. That is why the Moon is both the source of prophetic visions and illusions. Alchemists revered it as Diane-Trivia, keeper of secrets, but knew that its riddles were not always easy to decipher.
The planetary genius of the Moon, whether called Phul, Gabriel, or otherwise, is the guardian of nocturnal mysteries and vital fluids. It governs the ebb and flow of the tides as well as the humors of the soul. Its invocation traditionally aimed to increase intuition, fertility, and occult protection. At the threshold of the material world (the Moon being the last sphere before Earth in the Ptolemaic system), it links the cosmos and our domain: it is both the transmission factor (hence its role in astrological astronomy) and an autonomous magical entity granting the mage insight into hidden arcana. Thus ends the journey of the classical planetary geniuses – with the Moon opens the door to our sublunar world and closes those of the heavens.
Through these successive explorations from Saturn to the Moon, an overall vision emerges: that of a living cosmos, inhabited by intelligences and mediating geniuses linking man to the divine. The planetary geniuses are an integral part of pre-modern magical and astrological thought. Even though our modern perspective is now nourished by science and astronomical observation, it remains difficult not to be moved by the idea that each planet could harbor a benevolent or terrible spirit capable of influencing our destiny.
