A conjurer once recorded that when Marbas first appeared, the lion’s mane seemed to flicker like candlelight before the beast rose on two legs and became a man. The transformation was not a threat. It was a credential.
Marbas is a demon of the Ars Goetia, the fifth spirit listed in the Lesser Key of Solomon. He is a president of hell who governs 36 legions of spirits, and his domains include revealing hidden truths, curing and causing diseases, granting knowledge of mechanical crafts, and transforming the shapes of people.

Where Marbas First Appears in the Grimoires
The earliest known description of Marbas appears in Johann Weyer’s Pseudomonarchia Daemonum (1583), where he is called Barbas. Weyer, a Dutch physician and demonologist, compiled his list of infernal spirits from earlier manuscripts and oral traditions. He ranked Barbas as a great president who answers truly of things past, present, and to come, and who gives men the power to change their shape.
When the anonymous compilers of the Lesser Key of Solomon (the Lemegeton) produced their grimoire around the mid-17th century, they adopted Weyer’s description nearly verbatim but changed the name to Marbas. The text gives him the same rank, the same 36 legions, and the same abilities. A later edition by the occultist S.L. MacGregor Mathers in the 19th century preserved the entry without alteration.
Collin de Plancy included Marbas in his Dictionnaire Infernal (1818), illustrating him as a lion-headed figure with a serpent’s tail. That image, though embellished, fixed Marbas in the popular imagination as a beast-man hybrid.
The name itself may derive from the Hebrew marbes (to increase) or from the Aramaic barbas (confusion). Sources disagree. What matters is the consistency of the description across four centuries of grimoire tradition.
What Marbas Governs: Healing, Craft, and Transformation
The Ars Goetia lists three specific powers for Marbas. First, he answers truly of things hidden or secret. This includes past events, buried treasures, lost objects, and the intentions of others. Second, he causes and cures diseases. The grimoire does not specify which diseases, but the implication is that he can manipulate the humors or the subtle bodies that underlie physical illness. Third, he gives knowledge of mechanical arts and changes men into other shapes.
That last power is rare among Goetic spirits. Most can appear in different forms themselves, but Marbas can alter the conjurer’s own body. The grimoire warns that the transformation is temporary and that the spirit must be commanded to reverse it.
The mechanical arts clause is equally distinctive. Marbas is one of the few Goetic spirits associated with practical craftsmanship: engineering, clockwork, architecture, and the manipulation of materials. A practitioner seeking to understand a complex mechanism or to design a device might call on Marbas for insight.
The Lion and the Man: Symbolism of Marbas
Marbas first appears as a great lion. The lion in Western esotericism carries multiple meanings: royalty, solar power, the animal soul, and the guardian of thresholds. By presenting himself as a lion, Marbas asserts his rank as a president (a ruler beneath kings) and his connection to the elemental fire of the sun.
Only after the conjurer commands him does he take human shape. That sequence is deliberate. The lion represents the untamed force of nature and the raw potential of the spirit. The human form represents reason, speech, and the capacity for dialogue. Marbas demonstrates that he can bridge instinct and intellect, which is why he is suited to teaching mechanical arts (which require both intuition and logic).
The transformation also mirrors the alchemical process of coagula: the spirit condenses from a bestial form into a human one, making it accessible to the magician.
How Marbas Is Used in Ceremonial Magic
The conjuration of Marbas follows the standard Goetic procedure. The magician draws a circle, a triangle of art, and the spirit’s seal (which appears in the Ars Goetia as a complex sigil). The conjuration is spoken in a commanding tone, often in Latin or Enochian, and the spirit is bound to appear in the triangle.
Because Marbas is a president, he is considered relatively cooperative compared to kings like Paimon or Balam. He answers questions directly and does not typically deceive. However, the grimoire warns that he must be treated with respect. A dismissive conjurer may find the spirit slow to respond or prone to testing his authority.
Practitioners invoke Marbas for three main purposes:
- Healing: to diagnose an illness or to request a cure. The conjurer may ask Marbas to reveal the cause of a disease or to directly alter the patient’s condition.
- Discovery: to locate lost objects, uncover secrets, or understand hidden motives.
- Craft: to gain insight into a mechanical problem, to learn a new skill, or to design a device.
The grimoire does not prescribe offerings, but traditional Goetic practice includes a brass vessel, a wand, and a ring with the spirit’s seal. Some modern practitioners offer incense (frankincense or myrrh) and a candle of a color corresponding to the spirit’s nature (red or gold for Marbas, given his lion association).
Marbas Compared to Other Goetic Spirits
Marbas is often confused with Buer, who also has a lion-like appearance and governs healing. But Buer appears as a star-shaped figure with lion heads, teaches moral philosophy and herbal medicine, and commands 50 legions. Marbas is more focused on mechanical arts and shape-shifting.
Botis reveals past and future events, but Botis appears as a viper and then a man with great teeth. Marbas is more approachable in form and more practical in his knowledge.
Paimon is a king who teaches all arts and sciences, but Paimon is far more powerful and requires elaborate conjuration. Marbas, as a president, is easier to constrain and more suitable for focused, practical questions.
The closest parallel is perhaps Vassago, who also reveals hidden things and knows past, present, and future. But Vassago is a prince, not a president, and his description lacks the mechanical arts and shape-shifting.
Common Misconceptions About Marbas
The most persistent misconception is that Marbas is inherently evil or malicious. The grimoires describe him as “answering truly” and do not list him among the spirits that deceive or harm without cause. Like all Goetic spirits, he is a force of nature that can be directed. His ability to cause disease is a tool, not a disposition.
Another confusion is the name Barbas. Weyer used it, and some later texts treat Barbas and Marbas as separate spirits. They are the same entity. The variation likely comes from scribal errors in copying the Hebrew or Aramaic root.
Some modern sources claim Marbas is a lion-headed demon in the same category as Buer or Andras. In fact, Marbas only appears as a lion temporarily. His true form, after transformation, is human. The lion head is a phase, not a permanent attribute.
Finally, there is the idea that Marbas can grant permanent shape-shifting. The grimoire says he “changes men into other shapes,” but the context implies temporary transformation under the conjurer’s control. No reliable source claims Marbas can permanently alter a person’s form.
FAQ
Is Marbas dangerous to conjure? No more than any Goetic spirit. He is considered cooperative and truthful, but the conjurer must follow the protective rituals of the circle and triangle.
What does Marbas look like? He first appears as a great lion. When commanded, he takes a human shape. Some grimoires depict him with a lion’s head and a serpent’s tail, but that is artistic license.
Can Marbas cure any disease? The grimoire says he causes and cures diseases, but it does not specify limits. Traditional practice treats him as a spirit of healing, not a replacement for medicine.
How many legions does Marbas command? Thirty-six legions of spirits, according to the Ars Goetia. Each legion is traditionally 6,660 spirits, though the number is symbolic.
The Lion’s Knowledge
Marbas is not a spirit of terror. He is a president of practical knowledge: the kind that heals, builds, and reveals. His lion form reminds us that wisdom often arrives first as a beast we must learn to speak with. When the conjurer commands him to take human shape, the real work begins.
