Hydriel is one of the great wandering princes of the air described in the Ars Theurgia, the second book of the Lesser Key of Solomon. Unlike many infernal rulers who are assigned to a fixed point of the compass, Hydriel belongs to the wandering hierarchy and moves through the aerial regions with an enormous court of subordinate spirits.
His dominion is formidable. The text attributes to Hydriel one hundred great dukes and two hundred lesser dukes, while the number of spirits serving beneath them is described as virtually beyond calculation. Among this immense retinue, twelve dukes are singled out as the most important members of his court, and each of these principal spirits commands one thousand three hundred and twenty attendants of his own.
The twelve chief dukes begin with Mortoliel and Chamoriel, followed by Pelariel and Musuziel. Lameniel and Barchiel belong to the same ruling circle, as do Samiel and Dusiriel. The remaining members of Hydriel’s principal court are Camiel and Arbiel, together with Luciel and Chariel. Through these dukes, Hydriel governs an enormous network of subordinate aerial spirits.
The Planetary Hours of Hydriel
The spirits of Hydriel’s court are bound to particular periods of manifestation determined by the movement of the planetary hours. They may be approached during either daylight or darkness, but their appearance must correspond with the proper sequence assigned to them.
The first duke belongs to the first hour of the day or night, while the next follows during the succeeding period. The progression continues through Hydriel’s principal spirits until each has reached his allotted time.
This dependence upon magical timing is characteristic of the Ars Theurgia. Spirits do not simply exist as names available whenever the magician desires them. They occupy a supernatural order governed by rank, direction, movement, and time, and the magician is expected to understand that structure before attempting any interaction with them.
Hydriel’s wandering nature makes this particularly fascinating. Although his court is not confined permanently to one compass direction, it remains subject to a precise temporal order.
The spirits wander through space.
Their hours do not.
The Serpent Spirits of Hydriel
Hydriel’s dukes share an extraordinary manifestation.
When they become visible, they are described as taking the form of serpents possessing the heads and faces of beautiful young women. The image combines the human and serpentine in a form that appears repeatedly throughout ancient mythology and later demonological literature.
The serpent traditionally occupies an ambiguous place within occult symbolism. It can signify hidden knowledge and transformation while simultaneously evoking danger, temptation, and forces moving beneath the visible world. The beautiful female face adds another dimension, producing spirits whose appearance combines attraction with something distinctly inhuman.
Yet the spirits of Hydriel are not described as particularly hostile.
The Ars Theurgia characterises them as courteous and willing to obey, distinguishing them from more stubborn or malicious spirits encountered elsewhere in the same magical tradition. Their strange appearance therefore contrasts sharply with their reputed temperament.
These are serpentine demons who may look threatening but are described as comparatively cooperative when approached within the ritual order assigned to them.
Spirits of Water and Moist Places
Hydriel and his court possess a pronounced affinity for water.
His spirits are said to delight in places where moisture dominates the landscape, particularly areas surrounding rivers, lakes, marshes, wetlands, and other watery environments. Their association with such places gives Hydriel’s hierarchy a very different atmosphere from infernal spirits connected with deserts, ruins, mountains, or fire.
Water creates boundaries that are rarely permanent.
Shorelines shift, marshes conceal solid ground, reflections distort what appears above them, and mist transforms familiar landscapes into uncertain spaces. Such environments fit naturally with wandering aerial spirits whose own forms seem fluid and difficult to fix.
Hydriel therefore presides over a court that exists between several worlds. His spirits belong to the air but are drawn towards water, while their bodies combine the serpent with the human face. They wander rather than rule from a single direction, yet they remain tightly governed by their appointed hours.
Everything about Hydriel’s hierarchy seems to exist between states.
That quality makes him one of the more intriguing wandering princes of the Ars Theurgia.
Hydriel and the Hidden Architecture of the Ars Theurgia
Hydriel demonstrates why the Ars Theurgia cannot be understood as a simple catalogue of demons.
Behind a single prince lies an entire supernatural government. Hydriel commands great dukes who themselves govern enormous companies of spirits, while those spirits are simultaneously bound to particular manifestations and periods of activity.
The result is an infernal hierarchy of astonishing scale.
Hydriel is not merely one demon among many.
He is the centre of a moving court.
Around him travel hundreds of dukes and innumerable subordinate spirits, while the twelve most powerful members of his entourage emerge according to an invisible celestial timetable.
The Ars Theurgia therefore presents the spirit world almost as a parallel kingdom operating alongside the human one.
The magician does not create that order.
The magician attempts to understand it.
