No. 18 — Duke

Bathin

A duke of the air whose knowledge encompasses the properties and powers of all natural things, herbs, stones, and their hidden virtues.

Manifestation

Bathin manifests as a figure whose form seems to shift between organic and crystalline structures—sometimes appearing as a humanoid made of flowing plants and vines, sometimes as a being composed of geometric stones and minerals. Their presence brings the smell of growing things, rich earth, and the faint mineral scent of caves. Those who encounter Bathin report a sudden amplification of sensory perception, as though they can perceive the hidden properties and essences of all living and mineral things around them.

The demon's aura suggests profound knowledge concentrated in a form barely large enough to contain it. Being near Bathin feels like standing in a vast library where all knowledge is organized according to natural categories. The demon radiates neither malice nor benevolence but rather pure, impartial understanding of how the world actually functions.

Historical Origins

The emergence of Bathin within the Western grimoire tradition.

Bathin appears in the major European grimoire compilations of the sixteenth and seventeenth centuries, cataloged as the Duke of the Goetia's infernal hierarchy. The spirit commands 25 legions and holds dominion over matters of teaches herbs, stones, and virtues.

The name Bathin does not appear in pre-medieval sources with certainty, suggesting this spirit may represent a later codification of older folk beliefs about elemental air spirits, planetary venus intelligences, or localized spirits of place that were systematized during the great period of grimoire compilation.

What is certain is that by the time Johann Weyer published the Pseudomonarchia Daemonum in 1577, Bathin had been assigned a fixed position in the hierarchy, specific powers, and a defined method of conjuration — details that would be refined but largely preserved in the later Ars Goetia.

c. 1500s

Early Grimoire Appearances

Bathin appears in manuscript traditions circulating among European magical practitioners, though exact dates of first inclusion remain debated.

1577

Pseudomonarchia Daemonum

Johann Weyer includes Bathin in his systematic catalog of infernal spirits, establishing the demon's rank, legions, and primary powers.

c. 1600s

The Ars Goetia

The anonymous compilation that becomes the canonical source fixes Bathin's position as number 18 in the hierarchy of seventy-two, with refined descriptions of appearance and powers.

1818–1863

Dictionnaire Infernal

Collin de Plancy's encyclopedia brings Bathin to a wider audience, though with varying degrees of embellishment and artistic interpretation.

Grimoire Variations

How different sources describe Bathin across centuries of compilation.

Ars Goetia

Lesser Key of Solomon · c. 1600s

Bathin is the Duke of the Goetia, commanding 25 legions of spirits. Bathin possesses perfect knowledge of herbs, stones, and all natural things, revealing their properties, virtues, and hidden uses. He also grants the ability to traverse any distance instantly, carryi.

The canonical source. Establishes Bathin's position as number 18 in the hierarchy and defines the primary powers that subsequent sources would reference.

Pseudomonarchia Daemonum

Johann Weyer · 1577

Weyer's earlier catalog describes Bathin with similar attributes but often provides additional practical details about the spirit's temperament and the conditions required for successful conjuration.

Weyer's text predates the Ars Goetia and served as one of its primary sources. Differences between the two versions reveal how the tradition evolved over decades of transmission.

Dictionnaire Infernal

Collin de Plancy · 1818 / 1863

De Plancy's encyclopedia entry for Bathin draws primarily from the Ars Goetia but adds editorial commentary and, in the 1863 edition, an accompanying illustration by Louis Le Breton.

De Plancy's contribution is primarily visual and editorial — his encyclopedia brought these spirits to a general audience for the first time, framed as objects of scholarly curiosity rather than practical conjuration.

Grimoire Tradition

The Duke in the Western Magical Canon

Modern Practice

Contemporary Engagement

In modern occult practice, Bathin is approached through multiple frameworks — from traditional Solomonic ceremonial magick to psychological models that treat the demon as an archetype of teaches herbs, stones, and virtues. The spirit's domain over air and connection to Venus inform the timing and methods practitioners use.

Games & Media

Digital Afterlife

Like many spirits of the Goetia, Bathin appears across video games, tabletop RPGs, and fantasy literature — the Ars Goetia serving as one of gaming's most reliable bestiaries. Each adaptation preserves the core attributes while recontextualizing them for new audiences and media.

Ritual Traditions

Historical and modern approaches to working with Bathin.

Solomonic Ceremonial

The classical method requires a circle of protection, Bathin's seal inscribed on a lamen worn over the heart, and conjuration through graduated orations. The magician commands by divine authority, and Bathin appears within a brass triangle. Timing: Friday, during the planetary hour of Venus.

Grimoire Purist

Strict adherence to original manuscript instructions — hand-crafted tools, specific materials, precise ritual timing. The argument is that the grimoire's specific procedures create a coherent symbolic language. For Bathin, this means working with copper implements and air correspondences.

Psychological Model

Following the chaos magick tradition, Bathin is approached as an archetype — a personification of the practitioner's own capacity for teaches herbs, stones, and virtues. The seal becomes a meditation focus; invocation becomes active imagination. The circle is a psychological boundary.

Modern Devotional

A relational approach treating Bathin as an autonomous entity worthy of respect. Practitioners build ongoing relationships through offerings — typically incense, candles, or libations associated with Venus — and regular communication. The seal is displayed on an altar. Bathin is petitioned, not commanded.

Regardless of method, the irreducible correspondences remain: the seal is central, the element is Air, the planet is Venus, the metal is copper, and the day is Friday. These form the signal beneath the noise of varying approaches.

O Bathin, lord of herb and stone and tree,
Whose knowledge grants the hidden virtue's key,
From twenty-five legions of air I call thy name,
Grant me the sight to know each plant's true claim.

Bathin responds readily to those with genuine interest in natural knowledge, herbalism, or alchemy, particularly when invoked in gardens or wild places.
