Invoking Stolas in Magic: Powers, Correspondences & Dangers
Stolas is one of the more intellectually commanding spirits in the Ars Goetia — the catalog of 72 demons attributed to the legendary King Solomon and preserved most famously in the 17th-century grimoire The Lesser Key of Solomon. He is ranked as a Great Prince, he commands 26 legions of infernal spirits, and his domain is knowledge: specifically, the kind of deep, systematic knowledge that takes years to accumulate — astronomy, astrology, the properties of herbs, and the hidden virtues of gemstones. If you are drawn to invocation work that sharpens your mind, expands your esoteric education, or amplifies magical workings rooted in herbalism or crystal magic, Stolas is one of the most potent Goetic allies you can cultivate. This article is your starting point — who he is, what he can do for your practice, what to watch for, and how to approach him with real intention.
Who Is Stolas? The Prince of Knowledge in the Goetic Tradition
Stolas holds the 36th position in the Ars Goetia, placing him precisely at the midpoint of the 72-spirit hierarchy — a position that carries its own kind of symbolic weight. His rank is Great Prince of Hell, a title shared by only a handful of Goetic spirits. In the infernal hierarchy, Princes answer to Kings and outrank Dukes, Marquises, Counts, and Presidents. What that means practically is that Stolas carries authority. He does not scramble to be heard. When you call him correctly, he comes with presence.
His name appears in various spellings across historical sources — Stolas, Stolos, and occasionally Solas — all referring to the same spirit. The variation is a product of manuscript transmission errors and the imprecision of early modern demonological writing. In modern practice, Stolas is the dominant and most recognized spelling, and the one used in standard editions of the Ars Goetia.
His appearance, as described in the Ars Goetia, is that of a great raven or crow — a large, dark bird that, when commanded, takes on the shape of a man. The raven is not a random association. Ravens have been connected across cultures to hidden knowledge, prophetic vision, and the boundary between the living world and deeper unseen truths. In Norse mythology, Odin's ravens Huginn and Muninn — Thought and Memory — flew across the world gathering intelligence. The raven as Stolas's natural form is a deliberate symbolic signature: this is a spirit whose entire power is rooted in perception, observation, and accumulated wisdom.
Within the Goetic hierarchy, Stolas has no formal alliances described in the traditional texts, but his domain overlaps significantly with spirits like Aim and Andrealphus, both of whom touch on astronomy and transformation. He is not typically classified as a violent or aggressive spirit by Goetic standards — his energies run toward the intellectual and the arcane rather than the martial. That said, knowledge is its own form of power, and Stolas grants the kind of knowledge that has real-world consequences when applied. He is not harmless by nature of being an educator. He is a Prince of Hell who happens to teach.
His powers as listed in the Ars Goetia are threefold: he teaches the art of astronomy and the movements of the stars, he imparts full knowledge of herbs and plants including their magical and poisonous properties, and he reveals the virtues of precious stones. These are not surface-level areas of study — each one is a complete field of esoteric and practical knowledge. Practitioners who work with Stolas report deepened intuition in plant-based magic, accelerated understanding of astrological timing, and a heightened sensitivity to the energetic properties of crystals and minerals.
Stolas's Magical Correspondences
Correspondences are the symbolic language that magic runs on. Every tool, color, metal, herb, and planet you bring into a working carries a specific energetic signature, and when those signatures align with the spirit you are calling, your invocation carries more force. Think of it as tuning your signal — the more precisely your ritual environment reflects Stolas's nature, the cleaner the connection. Here are Stolas's core correspondences as understood in traditional and modern practice:
- Element: Air — Stolas's entire domain is knowledge, perception, and mental clarity. Air governs the intellect, communication, and the transmission of information, all of which sit at the center of what he offers.
- Direction: East — the direction of Air and of rising light, associated with new understanding, the dawn of knowledge, and clear-eyed vision.
- Planet: Saturn — Saturn governs deep time, esoteric wisdom, occult study, and the kind of disciplined, structural knowledge that Stolas imparts. His connection to astronomy also reinforces the Saturnian link to celestial mechanics and long cycles.
- Number: 36 (his position in the Goetia — use this number in candle arrangements, petition repetitions, or ritual timing); 26 (his legions — useful in workings where you want to invoke his full command); 8 (the number associated with Saturn and disciplined mastery)
- Colors: Black, deep indigo, midnight blue, and dark purple — colors of the night sky, hidden knowledge, and Saturnian depth
- Metals: Lead (Saturn's metal, grounding and heavy with esoteric tradition) and silver (associated with lunar and astronomical perception)
- Incense and Herbs: Myrrh, fumitory, and cypress for Saturnian resonance; mugwort and wormwood for their associations with vision and plant magic; black pepper and star anise for clarity and opening the senses to hidden information
- Stones and Crystals: Obsidian (protection, depth, truth-seeing), labradorite (cosmic awareness and connection to astronomical forces), black tourmaline (grounding during deep intellectual or spirit work), and sapphire (traditionally linked to wisdom and celestial alignment)
- Sigil: Stolas's unique sigil from the Ars Goetia — used as the focal point of any invocation or petition working
- Day: Saturday — Saturn's day, the most aligned timing for any work involving Stolas's areas of power
- Time: Midnight or the pre-dawn hours — the darkest point of the night sky, when astronomical observation is sharpest and the threshold between states of awareness is most permeable
When you build a working around Stolas, you are not just assembling props. Each correspondence you include is a signal — a declaration that you understand his nature and have made your space reflect it. A black candle, a piece of obsidian, myrrh burning in the dark, his sigil drawn in ink at the center of your altar — that combination speaks a coherent language. Your will does the actual work, but the correspondences align your environment with his frequency and sharpen the transmission.
If you are using Stolas in a specific context — say, a working to deepen your herbal practice or to improve your astrological timing in spell work — weight your correspondences toward that domain. For herbal workings, mugwort, wormwood, and green candles alongside the black create a productive layering. For astronomical or astrological amplification, labradorite and deep blue candles bring additional resonance. The core correspondences remain constant. You are just building on top of the foundation.
Dangers and Precautions Specific to Stolas
Most of what you will read about Goetic spirit work lists the same generic warnings: use a circle, banish afterward, do not approach recklessly. That advice is not wrong, but it does not tell you what is actually specific to Stolas. He is not a spirit who manifests danger through violence or chaos. His risks are subtler, and that makes them easier to miss until they have already taken root.
The first and most significant risk with Stolas is intellectual inflation. Stolas opens doors to knowledge — rapidly, and without much filter on whether you are ready for what comes through. Practitioners who work with him intensively sometimes report a sudden sense of authority on subjects they have barely touched, a feeling of having unlocked something vast. That feeling can become untethered from actual, grounded competence. You may know things you cannot yet apply, or believe you understand systems you have only glimpsed the surface of. In esoteric traditions, this is called spiritual pride — and it is one of the most practically damaging states a practitioner can fall into. If you begin working with Stolas and notice an outsized sense of certainty, slow down and test your knowledge against real practice before acting on it.
The second specific risk involves his domain of herbalism, particularly the poisonous properties of plants. The Ars Goetia explicitly notes that Stolas teaches the poisonous qualities of herbs — not just their healing or magical uses. If you are doing physical herbal work in conjunction with Stolas invocations, this is not a spirit who will automatically steer you toward safe applications. He teaches what is asked. Your discernment about how to use what you receive is your responsibility, not his. Never apply herbal knowledge gained in a ritual state without verifying it through established, reliable sources before any physical use.
Third, Stolas as a Great Prince operates with a kind of cold authority that does not particularly respond to ungrounded enthusiasm. Practitioners who approach him from a place of ego — trying to command him aggressively or treating the invocation as a power flex — report sessions that feel hollow, blocked, or disorienting. He is not hostile in those encounters. He simply does not engage. The precaution here is internal: come to him from a place of genuine pursuit of knowledge, not performance. He can tell the difference, and your results will reflect it clearly.
Historical Roots: Stolas Through the Centuries
The Ars Goetia as we know it dates to the 17th century, compiled as part of The Lesser Key of Solomon, but the spirit catalog it contains draws on much older sources. The foundational predecessor is the Pseudomonarchia Daemonum, published in 1577 by Johann Weyer as an appendix to his larger work De Praestigiis Daemonum. Stolas appears there in essentially the same form — a great prince, a raven, a teacher of astronomy and herbs — which places his formal demonological description as at least 16th century in written record.
Before Weyer, the lineage is harder to trace with certainty, but the cluster of attributes assigned to Stolas — avian form, astronomical knowledge, plant lore — maps onto a much older archetypal pattern. Raven and crow deities associated with cosmic knowledge appear across European, Near Eastern, and Northern mythologies. The Greco-Roman god Apollo had the crow as a sacred bird tied to prophecy and knowledge. In Celtic traditions, corvid figures were associated with battle wisdom and sight beyond the ordinary. Whether Stolas as a named spirit descended from any specific tradition or was constructed from this wider archetypal pool during the medieval demonological synthesis is an open scholarly question.
What is clear historically is that Stolas belongs to a broader category of Goetic spirits whose primary function is transmission of forbidden or hidden knowledge — the idea that certain forms of wisdom are held by non-human intelligences and can be accessed through ritual contact. This concept runs through Hermetic philosophy, Neoplatonism, Jewish mysticism, and medieval ceremonial magic alike. Stolas is one of the more coherent and consistent figures in the Goetic catalog across different manuscript versions, which suggests either careful transmission of his description or a widely shared intuition about what kind of being he represents.
Continue Exploring the Goetic Hierarchy
Every spirit in the Ars Goetia belongs to a rank — King, Duke, Marquis, Count, President, Prince, or Knight — and knowing where a spirit sits in that hierarchy is what turns a list of names into a real working knowledge of the tradition. If you're ready to see how Stolas fits alongside the other 71 spirits and the Princes he ranks among, read The 72 Demons of Solomon: A Complete Compendium by Rank. It organizes the full Goetic catalog by nobility and walks you through the powers and character of each spirit in turn.
