The Decans & Planetary Faces

The Decans and Planetary Faces

Chaldean Order, Egyptian Decans, Magical Images, and the Traditions of the Picatrix and Agrippa

Abstract

The thirty-six decans are among the oldest surviving subdivisions of celestial symbolism, yet they are also among the most frequently misunderstood. In contemporary astrology, decan, decanate, and face are often treated as interchangeable terms for a ten-degree division of a zodiac sign. Historically, however, several distinct systems converged upon the same thirty-sixfold structure.

The earliest Egyptian decans were stellar groups connected with calendrical reckoning and the measurement of the night. They were not originally thirty-six neat tropical zodiac sectors ruled by planets. During the Hellenistic and late antique periods, the decanal structure became zodiacalized, so that each sign contained three ten-degree divisions. These divisions acquired planetary rulers, images, gods, spirits, bodily correspondences, and eventually sophisticated talismanic applications.

Within medieval and Renaissance astrology, the most familiar planetary faces follow the so-called Chaldean order of the seven traditional planets. Parallel traditions, however, assign the decans according to elemental triplicities. The Picatrix preserves both conceptual layers, while Heinrich Cornelius Agrippa incorporates the faces and their mysterious images into his system of celestial magic.

The result is not one simple doctrine called “the decans,” but a historical complex composed of astronomy, astrology, image magic, planetary dignity, and Hermetic cosmology.

1. What Is a Decan?

In ordinary astrological usage, every zodiac sign of 30° may be divided into three equal parts:

• First decan: 0°00′–9°59′59″
• Second decan: 10°00′–19°59′59″
• Third decan: 20°00′–29°59′59″

Twelve signs multiplied by three divisions produces:

12 × 3 = 36 decans

This geometrical definition is straightforward. The historical meaning is not.

The thirty-sixfold division accumulated several different systems:

1. Egyptian stellar decans — groups of stars associated with ten-day periods and nocturnal timekeeping.
2. Zodiacal decans — thirty-six ten-degree sections incorporated into the zodiac.
3. Planetary faces — the same ten-degree sections receiving rulers according to the seven-planet Chaldean sequence.
4. Triplicity decans or decanates — another planetary attribution based upon successive signs of the same element.
5. Decanic images — anthropomorphic or symbolic figures associated with each ten-degree division.
6. Magical faces — decans used as specific celestial powers in astrological image magic.

A serious traditional astrologer should therefore resist saying simply, “the Egyptians invented the modern planetary decans.” That formulation compresses centuries of development into a single statement.

2. The Egyptian Decans Before Zodiacal Astrology

The historical roots of the decans lie in ancient Egypt.

The Egyptians organized their civil year into twelve months of thirty days, with an additional five epagomenal days. Each thirty-day month could be understood as three periods of approximately ten days. The thirty-six recurring ten-day divisions of the year corresponded to a succession of stellar groups conventionally called decans by modern historians.

These stellar groups were used in systems of nocturnal timekeeping. Their successive risings helped mark the passage of the hours during the night.

Decanal lists appear in Egyptian astronomical material, including the famous diagonal star tables found on Middle Kingdom coffin lids and later astronomical ceilings.

This earliest stage is crucial:

The Egyptian decans were originally stellar and calendrical phenomena, not simply thirty-six tropical zodiac segments ruled by Mars, the Sun, Venus, and so forth.

The familiar zodiacal system emerged only after considerable transformation.

The Thirty-Six and the Year

The mathematical elegance is obvious:

36 × 10 days = 360 days

The remaining five epagomenal days completed the 365-day Egyptian civil year.

The number thirty-six therefore belonged naturally to the structure of Egyptian sacred and calendrical time long before Renaissance astrologers engraved figures for “the first face of Aries” upon talismans.

3. From Egyptian Star Clocks to Zodiacal Decans

As Egyptian, Greek, Mesopotamian, and later Hermetic astrological traditions interacted, the decans underwent an important conceptual transformation.

Instead of functioning primarily as sequences of stars marking portions of the year and night, they became attached to the zodiac itself:

• three decans to Aries,
• three to Taurus,
• three to Gemini,
• and so forth.

Each acquired a ten-degree territory.

The thirty-sixfold celestial hierarchy was now embedded within the 360° zodiac:

360° / 36 = 10°

This zodiacalization allowed the decans to function directly in natal, electional, interrogational, and magical astrology.

A planet was no longer merely “in Scorpio.”

It might be:

Mars at 14° Scorpio, in the second face of Scorpio.

That ten-degree location could then possess:

• a planetary face ruler,
• a decanic image,
• an associated spirit or god,
• a magical virtue,
• particular iconography,
• and sometimes additional subdivisions or degree images.

Thus the decan became a bridge between the broad sign and the individual degree.

4. The Planetary Faces and the Chaldean Order

The most familiar traditional face rulers are based upon the seven classical planets:

Saturn → Jupiter → Mars → Sun → Venus → Mercury → Moon

This sequence is generally called the Chaldean order.

It reflects the traditional ordering of the planetary spheres according to their apparent speed and cosmological distance in the geocentric model:

1. Saturn
2. Jupiter
3. Mars
4. Sun
5. Venus
6. Mercury
7. Moon

The face sequence uses this same planetary cycle but is traditionally anchored with Mars ruling the first face of Aries.

The rulers then proceed:

Mars → Sun → Venus → Mercury → Moon → Saturn → Jupiter → repeat

This generates the classical table of planetary faces.

5. Complete Table of the Chaldean Planetary Faces

Notice something unusual at the end of the zodiac.

The third face of Pisces is ruled by Mars, while the first face of Aries is also ruled by Mars.

This is not an error.

Thirty-six faces do not divide evenly by seven:

36 = (7 × 5) + 1

The traditional sequence therefore produces the characteristic Mars-to-Mars junction around 0° Aries.

6. Why the Chaldean Order Matters

The Chaldean sequence is not merely a convenient list of rulers.

It also governs other important structures of traditional astrology, most famously the planetary hours.

The recurrence of the same sevenfold order reflects a cosmological principle: celestial influences descend through an ordered hierarchy.

The face ruler therefore acts as a secondary planetary coloration within the larger environment of the sign.

For example:

4° Scorpio

Scorpio is fundamentally a Mars-ruled fixed water sign.

Its first face is also ruled by Mars.

Mars is therefore strongly echoed.

15° Scorpio

The second face belongs to the Sun.

The Martial nature of Scorpio is modified by a Solar undertone involving visibility, authority, centralization, pride, illumination, kingship, or command.

25° Scorpio

The third face belongs to Venus.

The sign remains Scorpio, but Venus introduces themes of attraction, desire, alliance, beauty, pleasure, reconciliation, seduction, or attachment into a fundamentally Martial sign.

The face does not replace the sign ruler.

It qualifies it.

7. Face as an Essential Dignity

In medieval and Renaissance astrology, a planet located in its own face possesses a small degree of essential dignity.

William Lilly’s familiar numerical scheme gives:

• Domicile: +5
• Exaltation: +4
• Triplicity: +3
• Term/Bound: +2
• Face: +1

The face is therefore the weakest of the five commonly tabulated essential dignities.

But weak does not mean meaningless.

A planet possessing only face dignity is traditionally understood as having just enough authority to maintain itself.

Lilly gives the memorable analogy of a person who has little property or security but can still preserve some measure of status.

Most importantly:

A planet in its own face is not completely peregrine.

This distinction can matter in horary and electional judgment.

Nevertheless, face dignity should never be allowed to overwhelm stronger considerations.

A planet that is:

• combust,
• retrograde,
• badly afflicted,
• cadent,
• contrary to sect,
• severely debilitated,
• or ruled by a hostile dispositor

does not suddenly become excellent merely because it receives one point for face.

The face is a fine adjustment, not a rescue mechanism.

8. The Important Terminological Problem: Face and Decan Are Not Always Identical

Modern astrology frequently uses face, decan, and decanate interchangeably.

Historical sources are less consistent.

One especially important tradition distinguishes:

Planetary Faces

The rulers proceed according to the Chaldean sequence:

Mars → Sun → Venus → Mercury → Moon → Saturn → Jupiter

Triplicity Decans

The three decans of a sign are assigned according to the rulers of the three signs belonging to that elemental triplicity.

For example, the fire signs are:

Aries → Leo → Sagittarius

Their rulers are:

Mars → Sun → Jupiter

Thus the triplicity-based decans of Aries become:

• Aries I — Mars
• Aries II — Sun
• Aries III — Jupiter

Compare this with the Chaldean faces:

• Aries I — Mars
• Aries II — Sun
• Aries III — Venus

The systems agree at first and then diverge.

This distinction becomes particularly important when reading the Picatrix and Agrippa.

9. The Triplicity-Based Decanate System

For reference, the triplicity model produces the following scheme:

The logic is elemental rather than sevenfold.

For Taurus, for example, follow the earth signs:

Taurus → Virgo → Capricorn

and therefore:

Venus → Mercury → Saturn

For Pisces, follow the water signs:

Pisces → Cancer → Scorpio

giving:

Jupiter → Moon → Mars

Neither system should automatically be “corrected” into the other.

They belong to different streams of transmission.

10. Agrippa’s Remarkable Preservation of Both Systems

Agrippa provides unusually valuable evidence that the distinction was still meaningful in Renaissance magical astrology.

In Three Books of Occult Philosophy, Book II, he sometimes identifies a location simultaneously by its face and its decanate, assigning different planets to each.

For example, he describes the second face of Scorpio as belonging to the Sun while associating the corresponding decanate with Jupiter.

That is exactly what we would expect from the two systems:

Scorpio II

Chaldean face: Sun

Triplicity decanate: Jupiter
because the second water sign after Scorpio is Pisces, ruled traditionally by Jupiter.

Likewise, he can associate a Cancer face with one planet and its decanate with another.

This is an extremely useful warning for modern readers:

Do not automatically normalize historical terminology according to modern astrological software.

The text may intentionally be preserving two superimposed systems.

11. The Decans as Images Rather Than Merely Rulers

The planetary ruler is only one dimension of a face.

Perhaps the strangest and most fascinating tradition associates each of the thirty-six divisions with a specific image.

These are frequently human figures, although they may include:

• animals,
• weapons,
• tools,
• musical instruments,
• clothing,
• books,
• agricultural implements,
• crowns,
• serpents,
• birds,
• vessels,
• or scenes involving several people.

The images sometimes appear disturbing or contradictory.

A decan may simultaneously contain imagery of:

• wealth and greed,
• beauty and violence,
• justice and anger,
• sexuality and destruction,
• kingship and conflict.

This is important.

The decanic image is not merely a pleasant illustration of the planetary ruler.

It behaves more like a symbolic condensation of a specific celestial condition.

The image is the “face” shown by that portion of heaven.

12. Why Are They Called Faces?

The Latin facies literally means a face, appearance, form, aspect, or outward presentation.

This gives the concept greater depth than simply “ten-degree subdivision.”

A zodiac sign possesses three different countenances.

Aries does not present exactly the same celestial face throughout its thirty degrees.

The first ten degrees reveal one image.

The next ten reveal another.

The last ten reveal a third.

This idea becomes especially meaningful in astrological magic, where celestial forces are thought to descend into material forms through similarity.

The image therefore becomes a visible analogue of an invisible celestial quality.

13. Agrippa and the Thirty-Six Images of the Faces

Agrippa’s Three Books of Occult Philosophy, Book II, Chapter 37, gives a complete sequence of thirty-six face images.

He explicitly connects the tradition with Teucer and later Arabic authors.

The descriptions belong to a long chain of transmission and should not be mistaken for pristine Pharaonic Egyptian iconography.

They are better understood as a late antique, Arabic, and Renaissance development of the decanic tradition.

The following table summarizes Agrippa’s images and their major significations.

14. The Thirty-Six Faces: Images and Themes

Aries

Interpretation

Aries begins in extreme Martial force, rises toward Solar sovereignty, and concludes under Venus with the problem of transforming raw force into relationship, pleasure, form, or civilization.

The third face is particularly instructive: a Venus-ruled face does not make Aries “soft.” Venus must operate through Aries, producing desire and beauty within a fundamentally Martial environment.

Taurus

Taurus develops material form progressively.

Mercury measures and organizes it.

The Moon possesses and sustains it.

Saturn reveals the burden, necessity, limitation, and price of maintaining it.

Gemini

Gemini’s intellectual mobility becomes progressively more unstable.

Jupiter gives learning.

Mars intensifies activity.

The Sun can produce brilliant self-expression but also theatricality, pride, or speech that exists primarily to display itself.

Cancer

Cancer therefore cannot be reduced to passive domesticity.

Its third face, ruled by the Moon herself, is explicitly active and acquisitive: it seeks, tracks, protects, hunts, and captures.

Leo

The beginning of Leo is particularly interesting because Saturn rules the first face of the Sun’s domicile.

The symbolism is not simply “weak Saturn.”

Rather, Saturn gives structure, gravity, endurance, and consequence to Solar power.

Virgo

Virgo’s sequence emphasizes the complete material cycle:

production → accumulation → deterioration.

It is an excellent example of why decans can describe temporal processes rather than merely psychological characteristics.

Libra

Libra demonstrates another important principle:

justice is not necessarily passive harmony.

Its first images contain confrontation precisely because balance sometimes requires resistance to inequality.

Scorpio

The Scorpio faces are among the clearest demonstrations that planetary combinations cannot be interpreted by simplistic keywords.

Venus in a Martial water sign does not automatically mean romance.

It may describe desire entangled with control, jealousy, erotic intensity, attachment, or conflict.

Sagittarius

The Sagittarius sequence moves from directed action toward emotional uncertainty and finally toward hardened conviction.

This can describe the danger of belief becoming inflexible.

Capricorn

Capricorn’s images repeatedly concern resources, ambitions, calculation, and the consequences of worldly striving.

Aquarius

These images are strikingly different from the modern stereotype of Aquarius as purely idealistic or technological.

The traditional sequence emphasizes labor, intellect, social conduct, and the possibility of alienation.

Pisces

The zodiac concludes not with pure dissolution but with a remarkably embodied image of pleasure and repose.

Then Mars immediately rules the first face of Aries again, beginning another cycle.

15. The Picatrix and the Magical Faces

The Picatrix, the Latin name of the Arabic Ghāyat al-Ḥakīm, is one of the most important surviving texts of medieval astral magic.

Its significance for the decans is enormous.

The work does not treat the heavens merely as a system of abstract meanings. Celestial configurations can be deliberately embodied through:

• images,
• materials,
• planetary timing,
• suffumigations,
• inscriptions,
• ritual actions,
• and sympathetic correspondences.

The decanic images therefore become operational rather than merely interpretive.

A face is not simply something to describe.

Within astral magic, it is something that may be captured in an image under an appropriate celestial configuration.

16. Why the Magical Image Matters

The philosophical premise behind celestial image magic is that similitude creates receptivity.

An image corresponding to a celestial configuration is understood as a vessel capable of receiving that influence more effectively.

The magical image works through several layers simultaneously:

celestial configuration
+ symbolic image
+ appropriate material
+ planetary correspondence
+ electional timing
+ intention

The image is therefore not a decorative logo attached after the election.

It is part of the magical architecture.

This point is central both to the Picatrix and to Agrippa’s discussion of celestial images.

17. Agrippa’s Theory of Celestial Images

Agrippa explains that artificial things may receive celestial virtues when they are properly configured under suitable heavenly conditions.

His reasoning follows the broader doctrine of cosmic sympathy.

The superior and inferior worlds correspond.

An earthly image constructed in conformity with a celestial figure becomes analogous to a resonant instrument tuned to the same frequency.

Agrippa therefore stresses two forms of correspondence:

Material Correspondence

The substance should naturally correspond to the desired celestial power.

Formal Correspondence

The figure or image should resemble the relevant celestial form.

The closer the correspondence, the more suitable the object becomes as a receptacle of celestial influence.

This is the theoretical framework within which the thirty-six face images should be understood.

18. Picatrix Versus Agrippa

The two sources should not simply be collapsed into one.

Picatrix

The Picatrix is fundamentally a manual of astral magic.

Its interest lies in:

• celestial images,
• planetary spirits,
• magical elections,
• materials,
• suffumigations,
• prayers,
• magical operations,
• and philosophical explanations of astral causation.

Its decanic material belongs to this practical environment.

Agrippa

Agrippa’s Three Books of Occult Philosophy is an encyclopedic Renaissance synthesis.

He places the decanic images inside a vast hierarchy linking:

• natural philosophy,
• number,
• geometry,
• astrology,
• planetary magic,
• angelology,
• theology,
• and ceremonial practice.

Agrippa therefore preserves the images while systematizing them within a larger Renaissance occult philosophy.

Their Relationship

Many of Agrippa’s decanic descriptions closely resemble material transmitted through Arabic astrological magic and the Picatrix tradition.

But one should not assume that every phrase, object, color, or gesture is identical across:

• the Arabic Ghāyat al-Ḥakīm,
• different Latin Picatrix manuscripts,
• Agrippa,
• later Renaissance authors,
• or modern editions.

Transmission produces variation.

19. Manuscript Variation Is Not a Minor Problem

Decanic images are especially vulnerable to textual and artistic mutation.

A manuscript artist may misunderstand an unusual object.

A translator may interpret a word in several possible ways.

A description may change:

• a staff into a branch,
• a bone into a flute,
• one garment color into another,
• a bracelet into another circular object,
• a symbolic tool into an ordinary object.

Different traditions may also intentionally preserve different images.

Therefore, when reconstructing a historical decanic talisman, the practitioner should not casually combine:

• an image from Agrippa,
• a planetary ruler from a modern website,
• a color from an unrelated manuscript,
• a Golden Dawn tarot title,
• and a planetary spirit from another system

and then call the result “the traditional decan.”

It is a modern synthesis.

That may be legitimate if done consciously, but it should be identified as such.

20. Are the Agrippan Images “Egyptian Decans”?

Only in a qualified historical sense.

The thirty-sixfold framework ultimately descends from Egyptian decanal tradition.

But Agrippa’s images passed through many centuries of:

• Hellenistic astrology,
• Hermetic religion,
• late antique astrological iconography,
• Arabic astral magic,
• medieval Latin translation,
• and Renaissance occultism.

Calling Agrippa’s image of each face “the original Egyptian image” would therefore be historically misleading.

A better formulation is:

Agrippa preserves a Renaissance form of the magical decanic image tradition whose remote ancestry lies in the Egyptian thirty-sixfold celestial system.

That statement respects both continuity and transformation.

21. The Decanic Image Is Not Merely Psychological

Modern astrology frequently converts everything into personality description.

Thus a decan becomes something like:

“People born in the second decan of Scorpio are charismatic leaders.”

This approach captures only a fraction of the traditional material.

Historical decanic images describe:

• actions,
• professions,
• conflicts,
• economic conditions,
• diseases,
• journeys,
• erotic situations,
• warfare,
• agriculture,
• social hierarchy,
• justice,
• poverty,
• wealth,
• violence,
• craftsmanship,
• and magical operations.

They are not simply psychological archetypes.

A more sophisticated interpretation asks:

What kind of event, condition, process, role, or manifestation does this face portray?

That question is usually more productive.

22. How to Interpret a Planet Through Its Face

A reliable hierarchy is:

1. Planet

What is acting?

2. Sign

What environment and essential condition does the planet inhabit?

3. Sign ruler

Who governs that environment?

4. House

Where does the matter manifest?

5. Sect and planetary condition

How constructively can the planet express itself?

6. Aspects and applications

What is the planet doing and toward what is it moving?

7. Term and face

What finer layer of authority or expression modifies the planet?

8. Decanic image

What specific symbolic scene describes the manifestation?

This prevents the decan from being inflated beyond its proper role.

23. Example: Venus at 23° Scorpio

Venus is in Scorpio:

• a sign ruled traditionally by Mars,
• a sign contrary to Venus’s own domicile Taurus,
• therefore a potentially difficult essential environment for Venus.

At 23° Scorpio she lies in the third Chaldean face of Scorpio, which Venus herself rules.

This gives Venus a small amount of face dignity.

The traditional decanic image, however, remains intense and conflictual.

This combination is extremely instructive.

Venus has some local authority, but she must exercise it in Mars’s sign.

Thus one might expect Venusian matters to become:

• highly passionate,
• possessive,
• erotic,
• strategic,
• jealous,
• transformative,
• or entangled with power.

Her face dignity does not convert Scorpio into Libra.

Instead, Venus finds a narrow territory within Scorpio where she can operate in her own manner.

24. Example: Saturn in the First Face of Leo

The first face of Leo is ruled by Saturn.

At first glance this seems contradictory:

• Leo is the domicile of the Sun.
• Saturn is traditionally contrary to Solar warmth and vitality.

Yet this is exactly why face rulership becomes interesting.

Saturn inside Leo can symbolize the structure required to sustain sovereignty:

• responsibility,
• hierarchy,
• endurance,
• constraint,
• discipline,
• consequences of power.

The image of a figure riding a lion captures this beautifully.

The problem is no longer merely:

“Is Saturn good or bad in Leo?”

The more useful question becomes:

“What happens when Saturnian control must ride and govern Solar leonine power?”

That is the kind of symbolic precision the decans can provide.

25. Natal Astrology: Recommended Use

For natal interpretation, the faces are most effective as a fine-grained descriptive layer.

They are particularly useful for:

• the Ascendant,
• its ruler,
• the Sun,
• the Moon,
• the Lot of Fortune,
• the Lot of Spirit,
• the ruler of the relevant topic,
• and planets dominating major configurations.

Recommended Priority

Do not interpret:

planet → decan → personality

in isolation.

Instead use:

planet + sign + house + ruler + sect + aspects + condition → face

The face should refine an already established judgment.

It should rarely overturn it.

26. Horary Astrology: Recommended Use

In horary, face rulership has a precise traditional role as minor essential dignity.

If a significator has no domicile, exaltation, triplicity, or term dignity but is in its own face, it possesses at least a minimal claim to competence.

That matters.

But the weighting should remain proportional.

For example:

A significator that is:

• in its own face,
• retrograde,
• combust,
• cadent,
• and separating from the desired perfection

is still severely compromised.

The single face dignity should not be used to manufacture a positive judgment.

Use the face as supporting testimony.

27. Electional Astrology: Recommended Use

In ordinary elections, decans are best treated as refinements rather than foundations.

Prioritize first:

1. Ascendant and its ruler.
2. Moon.
3. Relevant house and significator.
4. Angular strength.
5. Applications.
6. Reception.
7. Avoidance of serious afflictions.
8. Essential dignity.
9. Sect and motion.
10. Only then finer subdivisions such as terms and faces.

A magnificent decan does not compensate for:

• a destroyed Ascendant ruler,
• a combust significator,
• a severely afflicted Moon,
• or a malefic dominating the principal angle.

The decan is precision, not structural repair.

28. Astrological Magic: The Priority Changes

In explicitly decanic talismanic work, the situation is different.

Now the face itself is the target.

Its:

• ruler,
• image,
• meaning,
• rising,
• planetary relationship,
• and source-specific instructions

may become central to the election.

This is why rules taken from ordinary natal or electional astrology cannot simply be copied mechanically into image magic.

A magical text may specifically demand:

• a particular face rising,
• its ruler in a particular condition,
• a planetary day or hour,
• the Moon free from certain afflictions,
• or a defined image constructed under that configuration.

The recipe matters.

29. Planetary Hour Alone Is Not Enough

A common modern simplification is:

“This is a Venus decan, so make the talisman during the hour of Venus.”

Historically this is inadequate.

Planetary hours are one layer of celestial timing.

A serious astrological election may also need to consider:

• the Ascendant,
• the face rising,
• ruler of the face,
• relevant planet’s dignity,
• angularity,
• combustion,
• retrogradation,
• planetary speed,
• applications,
• the Moon,
• malefic interference,
• and the instructions of the specific source.

A planetary hour cannot magically repair a disastrous celestial configuration.

30. Do Not Add Uranus, Neptune, or Pluto to the Classical Face Sequence

If the goal is traditional astrology or traditional astrological magic, the seven-planet structure should be preserved.

The Chaldean sequence is mathematically and cosmologically built from:

• Saturn,
• Jupiter,
• Mars,
• Sun,
• Venus,
• Mercury,
• Moon.

Adding Uranus, Neptune, or Pluto would not merely expand the table.

It would destroy the internal structure that generates the traditional sequence.

Modern astrologers may create experimental outer-planet decan systems, but they should not label them the classical planetary faces.

31. Do Not Confuse Decanic Magic with Golden Dawn Tarot Correspondences

The familiar association of the thirty-six decans with the numbered Minor Arcana:

• 2–10 of Wands,
• 2–10 of Cups,
• 2–10 of Swords,
• 2–10 of Pentacles

belongs to a much later layer of Western esotericism, especially the Hermetic Order of the Golden Dawn and related nineteenth- and twentieth-century systems.

These correspondences can be extremely valuable.

But they are not evidence for ancient Egyptian tarot decans.

The historical sequence is roughly:

Egyptian stellar decans
→ Hellenistic zodiacal decans
→ late antique and Arabic astrological images
→ medieval/Renaissance magic
→ modern Hermetic and tarot synthesis

Keeping these layers separate makes the whole system more meaningful, not less.

32. A Practical Method for Working with the Faces

For serious astrological research, the following method is recommended.

Step 1 — Identify the Exact Ten-Degree Division

Determine whether the planet lies within:

• 0°–10°,
• 10°–20°,
• or 20°–30°.

Step 2 — Identify the Chaldean Face Ruler

Use the traditional seven-planet table.

Step 3 — Examine the Ruler’s Actual Condition

Do not treat the face ruler as an abstract keyword.

Ask:

• Where is it?
• In what house?
• Is it dignified?
• Is it in sect?
• Is it direct?
• Is it combust?
• What does it aspect?
• Does it receive the planet occupying its face?

Step 4 — Read the Historical Image

Consult the relevant face image.

Do not reduce it immediately to one keyword.

Ask what the scene is doing.

Step 5 — Compare Source Traditions

Where necessary compare:

• Picatrix,
• Agrippa,
• other medieval image lists,
• later Renaissance authorities.

Step 6 — Separate Historical Layers

Ask whether you are examining:

• an Egyptian stellar decan,
• a Chaldean planetary face,
• a triplicity decan,
• a magical image,
• or a modern Hermetic correspondence.

Step 7 — Synthesize Only at the End

The best interpretation emerges from the interaction of these layers rather than from selecting whichever one produces the most attractive meaning.

33. Which System Should You Use?

For Medieval or Renaissance Horary

Use the Chaldean planetary faces as part of essential dignity.

This is the safest and most historically coherent choice.

For Traditional Natal Astrology

Use the Chaldean face ruler as a secondary or tertiary modifier.

The image tradition may then add symbolic nuance.

For Historical Decanic Research

Keep Egyptian stellar decans separate from later zodiacal faces.

Do not project Renaissance rulerships backward into Pharaonic astronomy.

For Picatrix-Style Astrological Magic

Follow the rulership, image, and electional instructions of the specific textual tradition being used.

Do not casually mix manuscript traditions.

For Agrippan Magic

Use Agrippa’s own face imagery and his broader theory of celestial images, correspondences, planetary conditions, and electional timing.

Read Book II as a system rather than extracting Chapter 37 in isolation.

For Modern Psychological Astrology

Decans may be used as symbolic refinements, but it is better to distinguish modern interpretive synthesis from historical doctrine.

34. The Most Important Rule: Source Before Synthesis

There is no single universal “decan system” that contains every historical attribution simultaneously.

A responsible practitioner should be able to say:

“I am using the Chaldean faces.”

or:

“I am using the triplicity decanates.”

or:

“I am studying the Picatrix face images.”

or:

“I am reconstructing Agrippa’s decanic imagery.”

That simple discipline prevents enormous confusion.

It also allows meaningful comparison.

35. Final Recommendations

The decans become most useful when treated neither as decorative subdivisions nor as miniature zodiac signs.

They occupy an intermediate scale.

A sign gives the broad territory.

A bound defines a more localized planetary jurisdiction.

A face gives the sign a particular countenance.

A degree may refine the symbolism still further.

For general traditional astrology, the following hierarchy is recommended:

Sign and ruler → planetary condition → house → aspects → sect → triplicity and bounds → face → image

For astrological magic:

Target celestial power → historical source → election → ruler → face/decan → image → material correspondences → ritual construction

Several principles should remain constant:

1. Do not identify the original Egyptian stellar decans with the later Chaldean face rulers without qualification.
2. Do not assume that face and decanate mean precisely the same thing in every historical text.
3. Use the seven classical planets when working with the Chaldean faces.
4. Treat face dignity as real but minor in ordinary astrological judgment.
5. Give the face greater importance when the face itself is the deliberate target of astrological magic.
6. Do not allow a favorable face to override severe planetary affliction.
7. Do not treat the magical images as literal personality descriptions.
8. Choose a textual lineage before creating a talismanic image.
9. Avoid silently combining Agrippa, the Picatrix, Golden Dawn, modern decan theory, and Egyptian iconography into an allegedly ancient single system.
10. Read the image as a dynamic scene rather than a static keyword.

Conclusion

The history of the decans is the history of astrology itself in miniature.

They begin as ancient Egyptian stars marking sacred time.

They enter the zodiac and become thirty-six celestial regions.

They receive planetary rulers.

They acquire gods, spirits, bodies, occupations, and images.

Arabic astral magicians transform them into instruments of celestial magic.

The Picatrix preserves their operational dimension.

Agrippa transmits them into the philosophical architecture of Renaissance occultism.

Later astrologers reduce the face to one point of essential dignity, while modern Hermeticists connect the same thirty-six divisions with tarot and ceremonial symbolism.

None of these developments completely erases what came before.

The result is a layered celestial language.

The Chaldean ruler tells us which planetary intelligence colors the face.

The zodiac sign tells us the field through which it must operate.

The historical image shows us what that combination looks like when it becomes form.

And the older Egyptian background reminds us why the decans are more than arbitrary slices of a horoscope: behind the thirty-six ten-degree divisions lies one of humanity’s oldest surviving attempts to divide celestial time into intelligible, sacred powers.

For the traditional astrologer, the face is therefore small but significant.

For the historian, it is a fossil preserving several civilizations inside one technique.

And for the practitioner of astrological magic, it is something still more profound:

a particular countenance through which the heavens were believed to reveal — and impress — their power upon the world below.
