The light of the night
he Moon is the lesser luminary — the light that governs the night, as the Sun governs the day. It is the body closest to the Earth and the fastest in the sky: it traverses the whole zodiac in about 27 days and changes sign every two and a half days. Because it moves so quickly and because it waxes and wanes continually, it became in the tradition the significator of all that changes, flows, and is transformed — the body, the humours, the tides of daily life. It is the leader of the nocturnal sect.

Observational curiosity: the Moon has no light of its own — it reflects that of the Sun. Hence its phases: waxing when it moves away from the Sun toward the opposition (full Moon), waning when it returns to it (new Moon). The tradition reads the waxing Moon as gaining force, and the waning as losing it.
The mythology: Selene and Artemis
The Greeks had more than one lunar figure. Selene was the Moon personified, the goddess who each night crossed the sky in her chariot of silver, sister of Helios (the Sun). Artemis, daughter of Zeus and Leto and twin sister of Apollo, was the virgin goddess of the hunt, of the woods, of childbirth, and of women — in time, identified with the Moon, especially in her wild and protective face.
The two faces say the same of the astrological Moon: the body that reflects and nourishes (Selene) and that protects the life which grows — childbirth, the mother, the body (Artemis). The Moon is, above all, the principle that receives, nourishes, and gives form.
In traditional astrology
Nature and sect
The Moon is a luminary — the lesser light — feminine, cold and moist by nature, of the nocturnal sect, of which it is the leader. It is neither benefic nor malefic in itself, but it is strongly tinged by that to which it joins, being so receptive. By its speed, it governs what is brief, mutable, and everyday.
Essential dignities
| Dignity | Sign(s) |
|---|---|
| Domicile | Cancer |
| Exaltation | Taurus (3°) |
| Detriment | Capricorn |
| Fall | Scorpio |
The Moon rules a single sign, Cancer — cardinal water, comfort, nourishment, the home. It is exalted in Taurus, where the fixed earth of Venus gives it rest and fecundity. In detriment, in Capricorn (opposite to Cancer), saturnine coldness dries up what the Moon wants moist and nourishing; in its fall, in Scorpio, martial heat wounds its receptive nature, producing intensity and withdrawal.
The Moon has its joy in the 3rd house — the place of comings and goings, of siblings and neighbours, of daily religion. Akin to its mutability and its incessant transit, there the nocturnal luminary recognizes itself, acting according to its moving nature.
What the Moon signifies
By nature, the Moon governs:
- The physical body and the constitution — more than any other planet;
- The mother and the women of the native's life;
- Nourishment, sustenance, and care — all that feeds and supports;
- The people, the multitude and the common everyday;
- memory, habits, and the fluids that wax and wane;
- among the metals, silver; in the body, the stomach and what receives and digests.
The condition of the Moon in the chart
The Moon is the most living and variable point of the chart, and the most dependent — it is judged by many testimonies. Its phase matters (waxing, gaining light and force; waning, losing it), its speed (fast is prompt and fluid; slow, sluggish), its dignity, and above all its dispositor — the ruler of the sign where it is, in whose state one reads how that Moon in fact expresses itself. Heed also the Moon void of course, when it completes no further aspect before changing sign: under it, the tradition says, "nothing new is concluded."
The Moon, being the closest to the Earth and the swiftest, is the one that most partakes of human affairs, receiving the influence of the others and transmitting it to the matters of the native.
Begin with the sign (element and quality) and the dignity of the Moon in it; pass to the dispositor and judge its state; then read phase, speed, and aspects. The Moon is never judged alone — it is a receptive luminary, and it always speaks in the company of the planet that rules it.
Conclusion
The Moon is the light that nourishes and the tide that moves all — the body, the mother, the everyday, the life that waxes and wanes. To read it in the traditional way is to weigh its phase, its dignity, its house, and, above all, its dispositor. Well disposed, it gives a solid constitution and a firm spirit; afflicted, it asks for care with the body and with the affections that oscillate to the rhythm of the inner tides.
