The rulers: rulerships, dignities and the ruler of the Ascendant

Every sign is governed by one body, its ruler. The table can be learned at a glance: the Sun rules Leo, the Moon rules Cancer, its neighbor. On either side of these two signs, the planets line up from the nearest to the Sun to the farthest: Mercury (Gemini, Virgo), Venus (Taurus, Libra), Mars (Aries, Scorpio), Jupiter (Pisces, Sagittarius), Saturn (Aquarius, Capricorn).

Three signs received a second ruler when the slow planets were discovered: Pluto for Scorpio, Uranus for Aquarius, Neptune for Pisces. These are their modern rulers, the ones the site and the trial use. Mars, Saturn and Jupiter remain their traditional rulers: keep them alongside.

A body in a sign it rules is in domicile: at home, it acts with its own means. In the opposite sign, it is in detriment: it works on someone else’s ground and has to adjust. For the dignities, Mars keeps its two signs of the tradition: it is in domicile in Aries as well as in Scorpio, and therefore in detriment in Libra and in Taurus.

The example sky shows both cases. Saturn in Capricorn is in domicile: rigor comes naturally there. Venus in Aries is in detriment, facing Libra: love learns candor and boldness there. A detriment takes nothing away from a body: it asks for an effort, which becomes a strength.

The seven bodies of the tradition also have a sign of exaltation, where they are honored: the Sun in Aries, the Moon in Taurus, Mercury in Virgo, Venus in Pisces, Mars in Capricorn, Jupiter in Cancer, Saturn in Libra. Opposite lies their fall: the Sun in Libra, the Moon in Scorpio, and so on.

In the example sky, Jupiter in Cancer is exalted: confidence unfolds widely there. Mercury, exalted in Virgo, rules it too: there we say domicile, and in Pisces, detriment. Most placements have no particular dignity and are read through the ruler of the sign. A dignity tells a comfort, never a verdict: in fall or in detriment, a body works harder, and that work makes its strength.

The Ascendant tells how you approach life; its ruler tells where you steer your strength. It is the pilot of the chart, and you find it in three moves: read the sign of the Ascendant, on the left of the wheel; name the ruler of that sign; look for that body on the chart and read its house.

In the example sky, the Ascendant is in Virgo: its ruler is Mercury, found in Taurus, in house 9. This chart steers its strength toward studies, travel and the search for meaning, with the patience of Taurus. The sign, the house and the aspects of the pilot color the whole chart.

The method of the Ascendant works for all twelve houses. Each house begins with a line, its cusp: the one you cross to enter it, moving counterclockwise. The sign where that cusp falls colors the house, and the ruler of that sign becomes the ruler of the house.

In the example sky, house 10 opens at the Midheaven, at 4° Gemini: its ruler is Mercury. Jupiter stands in it, but the occupant of a house is not its ruler. And an empty house is never silent: its sign colors it, its ruler says where its matters play out.

You can name the ruler of a house; now look for where it stands on the wheel. It seldom lives at home: it is in another house, and it carries the matters of its own house there. “The ruler of the 7th in the 10th” reads like this: partnership and associations run through career and public standing.

Direction matters: the house that is ruled depends on the house where its ruler stands, never the other way round. The ruler of the 10th in the 7th would say something else: career runs through associations. In the example sky, Mercury, ruler of house 10, is in house 9: career runs through travel, studies and meaning.

When two bodies each stand in a sign of the other, they are in mutual reception: each receives the other at home. Venus in Aries and Mars in Taurus, for instance: each is in detriment, but in the home of the other. They lend each other strength, and the link is worth an aspect. The example sky holds one: the Moon is in Sagittarius, a sign of Jupiter, and Jupiter in Cancer, the sign of the Moon.

You now know who rules what, how to tell a body at ease from a body at work, and how to follow a ruler from house to house. On your own chart, start with the pilot: the ruler of your Ascendant. Next night, you will learn how the bodies talk to one another: the aspects.
