The 17th Aethyr, called TAN, belongs to the middle portion of the thirty Aethyrs. In the system received by John Dee and Edward Kelley, the Aethyrs are names inserted into the Nineteenth Call and are linked with the governors of the terrestrial parts. In Aleister Crowley’s later record The Vision and the Voice, TAN became the setting for the path of Lamed and a vision of justice or universal balance. The two layers are related historically, but they should not be collapsed into one: Dee’s sixteenth-century documents provide the names, Call, and governors, while Crowley’s twentieth-century visions provide the most influential narrative interpretation.
This article explains TAN without treating one practitioner’s symbolism as an unquestionable map of reality. It distinguishes manuscript history, Crowley’s Thelemic commentary, later occult reception, and modern psychological or literary readings. That distinction is essential because the Aethyrs are often discussed as though Dee, Kelley, the Golden Dawn, Crowley, and contemporary scryers all reported the same cosmology. They did not.

Where the Aethyr Comes From
The name TAN comes from the list of thirty Aethyrs associated with the Nineteenth Call. The Call contains a variable position into which a chosen three-letter Aethyr name is inserted. Dee’s surviving material also assigns governors to the Aethyrs. For TAN, the commonly transmitted governor names are Sigmorf, Avdropt, Tocarzi. These names belong to a wider scheme of ninety-one governors distributed across thirty Aethyrs, with the outermost Aethyr receiving four governors and the others generally three.
The governor material should not be confused with Crowley’s visionary characters. A governor name is part of Dee’s table-based cosmology; a figure appearing in Crowley’s crystal or imagination belongs to a later visionary event. A modern article that calls every creature in a Crowley vision a governor creates a false historical equivalence. The distinction may seem technical, but it protects the reader from one of the most common errors in popular Enochian writing.
Crowley’s work with TAN belongs to a sequence begun in Mexico in 1900 and continued most fully in Algeria in 1909 with Victor Neuburg serving as scribe during much of the expedition. Crowley understood the sequence as an initiatory drama. His own synopsis defines TAN as the path of Lamed and a vision of justice or universal balance. That description is not a neutral translation of Dee; it is Crowley’s retrospective organization of the vision through Thelema, Qabalah, Tarot, and the grade structure of the A∴A∴.
Therefore, the safest historical formulation is precise: Dee and Kelley transmitted the name TAN, its place in the Aethyr system, and governing names; Crowley later produced the best-known detailed vision of TAN; subsequent occultists interpreted or revisited that record in different ways. The visionary content is evidence of what was reported and believed, not independent proof that the beings described exist as objective organisms.
The Visionary Architecture of TAN
Crowley’s record opens or develops around a formal visionary tribunal of scales, law, measured forces, and figures whose gestures turn ethical judgment into cosmic proportion. The scene matters because visionary texts communicate through arrangement before they communicate through doctrine. Location, color, direction, scale, movement, and the seer’s relation to the image form a grammar. In TAN, the arrangement places the reader inside a symbolic problem rather than merely presenting a list of supernatural names.
The leading figures include the angel of balance, judicial or priestly figures, and the seer placed before an impersonal standard. They do not all function in the same way. Some act as speakers, some as guardians, some as transformations of one another, and some may be visual condensations of an idea. Treating all of them as literal species of spirit erases the dramatic logic of the text.
The dominant themes are justice beyond revenge, equilibrium and consequence, self-judgment, and the danger of absolutizing private moral intuitions. These themes explain why TAN has continued to attract readers even outside Thelema. The vision stages a problem that can be read religiously, psychologically, aesthetically, or historically. Each lens reveals something, but no single lens exhausts the record.
Because TAN stands at rank 17, its imagery also gains meaning from sequence. The Aethyrs are not thirty interchangeable rooms. Crowley’s editorial framework presents movement from the outermost TEX toward the innermost LIL. LEA overturns former structures through a fiery and disruptive Kether symbolism associated by Crowley with a new authority. Reading TAN in isolation can therefore exaggerate a single image and miss the transformation enacted across neighboring Aethyrs.
The Major Symbols in Detail
Scales
In TAN, the scales is one of the central visual anchors. A symbol in a visionary text is not a dictionary entry with one permanent meaning. Its function depends on its position, movement, color, relation to the speaker, and relation to earlier and later scenes. Its specific importance here comes from the way it supports the Aethyr’s concern with justice beyond revenge.
A literal reading would ask whether the scales was an externally existing object. A source-critical reading first asks what Crowley recorded, what Neuburg could verify as scribe, what later editors added in commentary, and how the image relates to the path of Lamed and a vision of justice or universal balance. This sequence of questions preserves the force of the symbol without converting an extraordinary report into an untested factual claim.
Sword
In TAN, the sword is one of the central visual anchors. Crowley’s commentary often links the image to Tarot, Qabalah, astrology, and Thelemic doctrine. Those links are historically important because they show how he understood the experience, but they are interpretations layered onto the reported vision. Its specific importance here comes from the way it supports the Aethyr’s concern with equilibrium and consequence.

This sequence of questions preserves the force of the symbol without converting an extraordinary report into an untested factual claim.
Pillars
In TAN, the pillars is one of the central visual anchors. A comparative reader should ask what the image meant in Renaissance angelology, what it meant in late nineteenth-century ceremonial magic, and what it meant in Crowley’s personal system. The answers may overlap without being identical. Its specific importance here comes from the way it supports the Aethyr’s concern with self-judgment.

This sequence of questions preserves the force of the symbol without converting an extraordinary report into an untested factual claim.
Measured Paths
In TAN, the measured paths is one of the central visual anchors. Psychologically, the image can be read as a way the mind gives form to conflict, value, fear, vocation, or transformation. This reading does not prove that the vision was only psychological; it simply offers an accountable interpretive method. Its specific importance here comes from the way it supports the Aethyr’s concern with the danger of absolutizing private moral intuitions.

This sequence of questions preserves the force of the symbol without converting an extraordinary report into an untested factual claim.
Black Cross Of Themis
In TAN, the black cross of Themis is one of the central visual anchors. Literarily, the symbol contributes rhythm and structure. Repetition, reversal, impossible scale, and sudden transformation are not defects to be edited away. They are part of the genre of visionary writing. Its specific importance here comes from the way it supports the Aethyr’s concern with justice beyond revenge.

Four Interpretive Lenses
1. Historical Lens
Historically, TAN should be situated between Dee’s manuscript system and Crowley’s 1909 Thelemic project. The historical lens pays attention to dates, scribal roles, variant spellings, editorial layers, and later publication. It resists the temptation to quote a twentieth-century commentary as though it were spoken by Dee’s angels in the 1580s.
The governor names Sigmorf, Avdropt, Tocarzi belong to Dee’s received geography. Crowley’s scene of a formal visionary tribunal of scales, law, measured forces, and figures whose gestures turn ethical judgment into cosmic proportion belongs to a different documentary event. Placing both on the same page is useful, provided the difference is stated plainly.
2. Thelemic and Initiatory Lens
Within Crowley’s system, TAN is part of a coherent ascent and is summarized as the path of Lamed and a vision of justice or universal balance. The initiatory lens asks what change is demanded of the seer, what former identity becomes inadequate, and how the Aethyr prepares the next stage. This makes the vision more than a catalogue of marvels.
A responsible Thelemic reading also remembers that Crowley’s own symbolic claims were historically situated. His language about new and old Aeons, masters, gods, gender, and authority should be studied rather than simply repeated. Critical reading is not hostility; it is the condition for understanding how a system was constructed.
3. Psychological Lens
Psychologically, TAN can be approached as a structured encounter with justice beyond revenge and equilibrium and consequence. The figures may represent autonomous-seeming complexes, idealized authorities, feared possibilities, or creative syntheses. The important point is not to diagnose the seer from a distance, but to notice how the narrative organizes attention and conflict.
Visionary states can feel more vivid and authoritative than ordinary thought. That intensity does not automatically validate every interpretation made during or after the event. Journaling, comparison, rest, and willingness to revise are more reliable than treating emotional force as proof.
4. Literary and Comparative Lens
As literature, the vision of TAN uses compressed images, sudden metamorphosis, ritual speech, and impossible perspective. It can be compared with apocalyptic literature, mystical ascent texts, dream reports, and visionary poetry without claiming that all these genres describe the same metaphysical place.
Comparative study is strongest when it identifies both similarity and difference. A throne in one tradition may symbolize sovereignty; in another it may stage judgment; in another it may simply reflect the reader’s expectations. Parallel imagery is evidence of shared human and cultural forms, not automatic evidence of a single hidden doctrine.
How TAN Connects to the Neighboring Aethyrs
The preceding Aethyr in the outward-to-inward reading is ZEN. Moving from ZEN to TAN changes the symbolic problem rather than merely increasing intensity. The reader should track which images disappear, which return in altered form, and whether the speaker becomes more personal, more abstract, or more difficult to identify.
The next Aethyr is LEA. LEA overturns former structures through a fiery and disruptive Kether symbolism associated by Crowley with a new authority. This connection is valuable for internal linking because it lets readers follow an argument across the entire series instead of landing on seventy isolated pages.
Within the full sequence, TAN is best understood as a transition with its own integrity. It carries forward unresolved material, gives it a distinctive dramatic form, and hands a transformed question to the next Aethyr. The sequence does not demand that every reader accept Crowley’s metaphysics; it asks the reader to notice the architecture of transformation.
What the Vision Does Not Prove
- It does not prove that every figure appeared as an objectively measurable being.
- It does not show that Dee and Kelley had the same vision as Crowley.
- It does not make Crowley’s later Qabalistic commentary identical with the original record.
- It does not justify dangerous ritual behavior, coercion, sleep deprivation, drugs, or self-harm.
- It does not replace medical, psychological, legal, or financial judgment.
The value of TAN does not depend on making claims stronger than the evidence. The text is already valuable as a document of modern occultism, a sophisticated symbolic composition, a record of altered consciousness, and a node in the long reception of Dee’s angelic materials.
Frequently Asked Questions
What does TAN mean?
TAN is the three-letter name used for the 17th Aethyr. The manuscripts present it as a name inserted into the Nineteenth Call. Any claim that the letters have one final English translation should be treated cautiously because Enochian spelling, pronunciation, and later attributions vary.
Who rules the TAN Aethyr?
The commonly transmitted governors are Sigmorf, Avdropt, Tocarzi. They belong to Dee’s governor scheme. They should not automatically be identified with every angel, animal, voice, or symbolic figure in Crowley’s later vision.
What is the central message of TAN?
Crowley’s synopsis centers on the path of Lamed and a vision of justice or universal balance. A broader interpretation emphasizes justice beyond revenge while recognizing that the record contains several layers and does not reduce to a single slogan.
Did Victor Neuburg see the same beings?
Neuburg served primarily as scribe and ritual collaborator during the Algerian workings. His presence supports the documentary reality of the sessions, but the published record does not provide a second, independent, matching visual report for every scene. It is more accurate to call him a witness to the procedure and speech than a co-seer of identical images.
Can the Aethyr be read without practicing magic?
Yes. It can be studied as history of religions, Western esotericism, visionary literature, reception of Renaissance manuscripts, psychology of imagery, or comparative mysticism. Close reading is not a lesser form of engagement.
Conclusion
The 17th Aethyr TAN is significant because it combines Dee’s inherited Aethyr framework with Crowley’s later vision of a formal visionary tribunal of scales, law, measured forces, and figures whose gestures turn ethical judgment into cosmic proportion. Its symbols revolve around justice beyond revenge, equilibrium and consequence, self-judgment, the danger of absolutizing private moral intuitions. Read historically, it reveals how a Renaissance angelic catalogue became a modern initiatory epic. Read symbolically, it offers a disciplined way to think about transformation without requiring the reader to confuse intensity with proof.
