The moon changes its face every night. It is born as a thin thread, grows to the full disc, wanes and disappears for a few nights before returning. No other object in the sky shows so clearly the cycle of birth, fullness, decline and rebirth. This is why the moon is one of the richest symbols in every culture: linked to time, night, the waters, the feminine and dreams. In this article we look at the moon as a symbol, in images and myths.
The moon and the measure of time
Before becoming a spiritual symbol, the moon was a clock. Many ancient calendars were lunar or lunisolar, and even today the Islamic calendar is entirely lunar, while the Jewish calendar combines lunar months with the solar year. The date of Christian Easter also depends on the moon: it is celebrated on the Sunday after the first full moon of spring.
The very word "month" is linked, in many European languages, to the name of the moon. The lunar cycle was therefore the first great rhythm shared by humanity.
The symbolic meaning of the phases
| Phase | Image | Symbolic meaning |
|---|---|---|
| New moon | the moonless sky | hidden beginning, seed, silence |
| Waxing moon | the widening crescent | growth, momentum, plans taking shape |
| Full moon | the luminous disc | fullness, revelation, completion |
| Waning moon | the narrowing crescent | release, gathering in, purification |
In European folk traditions the phases of the moon also governed practical work: sowing, cutting wood, bottling wine. Whatever the practical value of these beliefs, they show how deeply the moon was woven into daily life.
The crescent moon
The crescent is one of the most recognisable forms of lunar symbolism. It appears:
- on the heads of lunar goddesses such as Artemis and Diana;
- beneath the feet of the Virgin in the iconography of the Immaculate Conception, inspired by the "woman clothed with the sun, with the moon under her feet" of Revelation;
- in many emblems and flags of the Islamic world, often accompanied by a star.
The crescent represents the moon in its moment of growth or decline: not fullness, but movement, becoming.
Lunar deities
The ancient world gave the moon many faces:
- Selene, in Greek mythology, is the personified moon, crossing the sky in a chariot;
- Artemis, and the Roman Diana, is the goddess of the hunt, the woods and moonlight, protector of women in childbirth;
- Hecate is linked to crossroads, night and passages, often depicted with three faces.
In modern readings these three figures have sometimes been brought together in the image of a "triple goddess" corresponding to the three visible phases of the moon. It should be said that this is a recent interpretation, not a unified cult attested in the ancient world. In other cultures the moon is masculine: in Mesopotamia it was the god Sin, and in Germanic mythology the moon is a male figure.
The moon in alchemy
In alchemical language metals were associated with the heavenly bodies. The moon corresponded to silver, the white, shining metal that reflects light as the moon reflects the sun's. In the alchemical work the sun and moon represent two complementary principles, often depicted as a king and queen whose union produces the philosophers' stone.
The stage of purification, the albedo, was also called the "white work" and connected with the moon: a reflected, calm light that comes before the full light of the sun.
The Moon arcanum
In tarot, arcanum XVIII shows the moon in the sky, two dogs or a dog and a wolf howling at it, two towers and a crayfish emerging from a pool of water. It is the card of the unconscious, of night fears, imagination and illusion. Moonlight lets you see, but it distorts outlines: what is seen at night must be interpreted with caution.
The Studio's reading
For Studio Esoterico Cornelio the moon teaches the value of cycles. Not every moment of life is one of growth, nor should it be. There are phases of gathering in and phases of silence, as necessary as those of fullness.
An exercise for a whole month:
- look at the moon every evening it is visible, even for just a minute;
- note the phase and one word about your state of mind;
- at the end of the cycle reread your notes and observe how your relationship with the different phases changes.
In short
- The moon, with its phases, is the clearest symbol of the cycle of birth, fullness and decline.
- It was the first measure of time and still governs several religious calendars.
- The crescent moon appears in the iconography of goddesses, of the Virgin and in Islamic symbols.
- In alchemy the moon corresponds to silver and to the white work.
- Arcanum XVIII represents the unconscious and invites caution in interpreting what you see.
