THE IDEA

Domicile is a planet's own sign; exaltation and depression are another pair of opposite places. One table shows them all.

FIGURE / dignityTableSHILAI · ATLAS
Domicile, exaltation and depression for the seven planets, after Tetrabiblos I.17 and I.19.

Table: the Sun rules Leo, exalted in Aries and depressed in Libra; the Moon rules Cancer, exalted in Taurus, depressed in Scorpio; Mercury rules Gemini and Virgo, exalted in Virgo, depressed in Pisces; Venus rules Libra and Taurus, exalted in Pisces, depressed in Virgo; Mars rules Scorpio and Aries, exalted in Capricorn, depressed in Cancer; Jupiter rules Sagittarius and Pisces, exalted in Cancer, depressed in Capricorn; Saturn rules Capricorn and Aquarius, exalted in Libra, depressed in Aries.

01

Domicile is the sign each planet is given as its own; seven planets share out all twelve signs.

Domicile: a planet's own sign

A planet in a sign it rules is often said to be stronger, as if at home: what that planet stands for comes more easily and naturally.

Later interpretation

The table holds seven planets: the Sun and Moon take one sign each, and Mercury, Venus, Mars, Jupiter and Saturn take two each, which uses up all twelve signs.

How to look it up: find which sign your Venus is in, then see that Venus rules Libra and Taurus. If it is in one of them, Venus is in its own sign. Check the other planets the same way, one at a time.

Reflection prompt

What the old texts say: Ptolemy's Tetrabiblos, Book I ch. 17, reasons like this. Cancer and Leo are closest to our zenith and make the most heat, so they go to the two lights: masculine Leo to the Sun, feminine Cancer to the Moon. The half-circle from Leo to Capricorn counts as the Sun's and Aquarius to Cancer as the Moon's, and each of the five planets takes one sign on each side. Saturn, coldest and furthest, takes Capricorn and Aquarius opposite; Jupiter, moderate, the next pair, Sagittarius and Pisces; Mars, dry, Scorpio and Aries; Venus, mild and fertile, Libra and Taurus; and Mercury, never more than one sign from the Sun, the remaining Gemini and Virgo.

02

Exaltation is another special place for a planet, and depression sits directly opposite it.

Exaltation and depression

Exaltation is often read as a place where a planet can really show what it does; depression as a place where it works harder and takes more effort.

Later interpretation

Depression is always directly opposite exaltation: the Sun is exalted in Aries, so its depression is Libra opposite; the Moon is exalted in Taurus, so its depression is Scorpio opposite. Remember the exaltation and you can work out the depression.

Derived calculation

When someone writes “Venus in Pisces: exalted,” you can trace the reason: Venus is moist, and Pisces is where the moist spring begins. Once you know the reason it is easy to remember, and easier to sense what that placement is about.

Reflection prompt

What the old texts say: Book I ch. 19 goes planet by planet. In Aries the Sun turns north, days lengthen and its heat grows, so it is exalted in Aries and depressed in Libra; Saturn, standing opposite the Sun, is exalted in Libra and depressed in Aries. The Moon starts to grow brighter after meeting the Sun in Aries, and is exalted in Taurus, the first sign of her own triangle, with Scorpio opposite as depression. Jupiter reaches furthest north in Cancer and is at full strength, so it is exalted in Cancer and depressed in Capricorn; Mars, fiery by nature and fiercer furthest south in Capricorn, is exalted there and depressed in Cancer; Venus, moist, is strongest in Pisces where the moist spring begins, so exalted there and depressed in Virgo; and Mercury, drier, is the reverse: exalted in Virgo, the dry autumn, and depressed in Pisces.

Put the chart page next to this table and you can find which kind of place each planet is in.

Using it on your chart

The chart page lists the sign each planet is in. Put it next to this lesson's table and you can find for yourself which planets are in domicile and which in exaltation or depression.

How this tool works

Once you have found them, ask yourself: does what the planet in its domicile or exaltation stands for come especially easily to me? Does the one in depression take a little more effort, or a longer way round?

Reflection prompt

One placement is one clue, read together with the rest. Next time another site says “Venus in Pisces: exalted,” you will know where that comes from, and remember to look at that Venus's aspects and the house it falls in as well.

Reflection prompt

What the old texts say: Book I ch. 17 opens by saying a planet's closeness to the signs comes in several kinds, including houses, triangles, exaltations and terms; chs. 20 and 21 then give two different systems of terms, the Egyptian and the Chaldaean, and note that the Egyptian one is not consistent in order or amount. Classical strength is a set of linked rules.

OBSERVE YOUR OWN CHART

Look at my chart

Your turn: put the chart page next to this lesson's table and check one planet at a time.

  1. Check the table: is any planet in a sign it rules?
  2. Then check: is any in its exaltation or depression?
  3. Write one line: does what your planet in domicile or exaltation stands for come easily to you?

Without a birth time, rising sign and houses stay blank.

LOOK CLOSER

A common mix-up

“A planet in exaltation makes someone superior.”

The reasons for exaltation are seasons, direction and hot, cold, dry and moist: the planet and sign suit each other. It describes how a planet acts and ranks no one.

“A planet in depression is bad.”

Depression sits opposite exaltation and is often read as a planet working harder and taking more effort. It describes a way of doing things, not good or bad, and not something you cannot do.

“You have to memorise the whole table to use it.”

Two patterns are enough: domicile spreads out evenly from Leo and Cancer on both sides, and exaltation and depression are always opposite. The rest you can look up.

CHECK YOURSELF

Now, try it yourself.

1. Why does the old text give Leo to the Sun and Cancer to the Moon?
2. The Sun is exalted in Aries. Where is its depression?

  1. Ptolemy, Tetrabiblos, trans. F. E. Robbins (Loeb Classical Library, 1940)

    Book I ch. 17 starts from Cancer and Leo being nearest our zenith and most productive of heat, assigns them to the Moon and the Sun, and then distributes the rest by semicircle, planetary nature, orbital distance and aspect: Saturn Capricorn and Aquarius, Jupiter Sagittarius and Pisces, Mars Scorpio and Aries, Venus Libra and Taurus, Mercury Gemini and Virgo — noting that Mercury never goes more than one sign from the Sun and Venus no more than two. Ch. 19 explains each exaltation and depression with its seasonal reasoning. Ch. 20 notes two systems of terms, Egyptian and Chaldaean, and that the Egyptian one is inconsistent in order and quantity. “Stronger in its own sign” and exaltation as a bonus are later shorthands; outer-planet rulerships have no classical source; and this app implements none of these judgments, for the reason the lesson gives.

Limits of this lesson

Domicile, exaltation and depression are tools for describing what a planet is like, for getting to know yourself; they do not rank people or charts.
