A 17th-century magician copying the Ars Goetia into his grimoire paused at the name. Barbatos. It sounded like it belonged in a Homeric hymn, not a list of infernal princes. He wrote it down anyway. Today, that name still trips up readers who assume any figure with a Greek-sounding name must come from Greek mythology. They are wrong. But the mistake is understandable.
Barbatos is a duke of Hell in the Ars Goetia, the first book of the Lesser Key of Solomon. He commands thirty legions of spirits, appears with four crowned kings and a trumpet, and grants the ability to understand the speech of animals, locate hidden treasures, and reconcile friends. He has no place in Greek mythology. His name, however, carries Greek echoes that deserve examination.
Where Did the Name Barbatos Come From?
The Ars Goetia was compiled in the mid-17th century, drawing on earlier grimoires such as the Pseudomonarchia Daemonum (1583) by Johann Weyer and the Steganographia of Johannes Trithemius. Weyer listed a spirit called Barbatos as a duke, and the Lesser Key manuscripts (Sloane MS 3825, c. 1670) preserved the name. The etymology is debated.
Most scholars trace Barbatos to the Greek barbaros (βάρβαρος), meaning “foreign” or “non-Greek.” In ancient Greece, barbaros described anyone who did not speak Greek – the word was onomatopoeic, mimicking the “bar-bar” sound of unintelligible speech. By the Renaissance, barbaros had acquired connotations of the uncivilized, the wild, the other. A demon named Barbatos would therefore be the “foreign one,” the outsider spirit.
A minority of sources link the name to a corruption of Berith (another Goetic demon) or to the Latin barbatus (bearded). Neither has strong manuscript support. We follow the barbaros derivation because it aligns with the spirit’s attribute of understanding animal languages – the speech of beasts was as incomprehensible to humans as barbarian tongues were to Greeks.
What Barbatos Offers the Magician
The Ars Goetia gives Barbatos a short but specific list of powers. He can make the magician understand the voices of birds, dogs, and all other creatures. He can break open hidden treasures that have been sealed by enchantment. He can reconcile quarreling friends and reconcile enemies with their rulers. He appears with four kings and their companies, and he sounds a trumpet when he comes.
These powers cluster around a single theme: mediation between worlds. The animal speech ability is the most striking. In medieval and Renaissance thought, animals were believed to possess their own forms of knowledge – birds knew the weather, dogs sensed spirits, wolves understood the wild. A spirit who could translate that knowledge was a gatekeeper to a hidden ecology of meaning.
The treasure-finding power is more practical. Barbatos is not a treasure guardian; he is a revealer. He shows where things are hidden, often by breaking the magical seals that protect them. This aligns him with other Goetic spirits who specialize in discovery (e.g., Buer, who teaches natural philosophy, or Vassago, who declares past and future). The reconciliation power rounds out the profile: Barbatos restores harmony, whether between men or between man and nature.
How Barbatos Is Summoned
The Ars Goetia prescribes a precise ritual for invoking Barbatos. The magician draws his seal – a complex sigil featuring a central cross, four points, and curved lines – on virgin parchment using the blood of a black bird or the ink of a holy man. The seal is placed within a triangle of art, and the magician recites the appropriate conjurations from the Lesser Key.
Timing matters. Barbatos is most easily called when the sun is in the sign of Sagittarius, the archer. Sagittarius is a fire sign associated with travel, foreign lands, and the pursuit of knowledge – all fitting for a spirit whose name means “foreign.” The magician wears a ring inscribed with the seal and a crown of paper or cloth. He faces east, the direction of the rising sun and of revelation.
We should note that these instructions come from a grimoire tradition that treated spirits as fallen angels bound by Solomon. The magician does not worship Barbatos; he commands him through divine authority. The tone is hierarchical, not devotional.
Barbatos and Greek Gods: A Comparison
No ancient Greek text mentions Barbatos. He does not appear in Hesiod, Homer, or the Orphic hymns. But his attributes echo certain Greek deities in a way that may have influenced the grimoire authors.
Hermes is the closest parallel. Hermes was the messenger god, the psychopomp who guided souls, the patron of travelers and thieves. He also understood the languages of animals – in one myth, he taught the seer Melampus to understand the speech of birds and worms. Barbatos’s ability to interpret animal voices mirrors this. Hermes also carried a herald’s staff (the caduceus) that could reconcile enemies, a power Barbatos shares.
Apollo is another candidate. Apollo was the god of prophecy, music, and healing. He spoke through oracles in a voice that required interpretation. Barbatos’s trumpet blast and his association with kings suggest a heraldic role similar to Apollo’s. But Apollo was never a demon; he was a major Olympian.
The difference is crucial. Greek gods were worshipped with temples, sacrifices, and hymns. Barbatos is a spirit to be bound and commanded. The grimoire authors borrowed names and traits from classical sources, but they recontextualized them within a Christian demonological framework. Barbatos is not a degraded god; he is a literary creation that repurposed Greek material.
What People Get Wrong About Barbatos
The most persistent error is the belief that Barbatos is a figure from Greek mythology. This mistake appears in online forums, pop-culture demonology lists, and even some occult blogs. The reasoning is circular: his name sounds Greek, and he has powers that resemble Greek myths, therefore he must be Greek. It is not true.
A second misconception is that Barbatos is evil in the sense of a malevolent devil. The Ars Goetia treats all demons as fallen angels, but Barbatos’s powers are neutral or beneficial. He helps the magician find treasure and make peace. He does not tempt, corrupt, or destroy. The grimoire warns that he can be dangerous if disrespected, but that is true of any spirit.
A third error is the claim that Barbatos appears in the Testament of Solomon. He does not. That text lists many demons, but Barbatos is absent. His first appearance is in Weyer’s Pseudomonarchia Daemonum.

He belongs not to the pantheon of Homer but to the pages of the Ars Goetia, where foreignness became a demonic title.
