Origin 100 BCE to 200 CE

The Moon governs the inner life: emotion, instinct, memory, habit, and the rhythms of need and nurture. In myth she is Selene crossing the night sky, Artemis the wild huntress, and Roman Luna, the ever-changing goddess whose phases measure time. Fastest of the seven traditional lights, she reflects the Sun rather than shining of her own, and so she signifies how we respond, feel, and are fed rather than how we choose. She rules the sign Cancer and is exalted in Taurus, in detriment in Capricorn, and in fall in Scorpio, at ease where feeling and security are honored and strained where control or intensity rules. Psychologically she is the unconscious, the mother, the child within, and the felt sense of belonging. In the body she rules the stomach, breasts, and bodily fluids and tides; she governs Monday; her metal is silver; and her colors are white, silver, and pale sea-tones.

The Moon as a Classical Planet

The Moon is the second luminary, ruling Cancer as its sole domicile, exalted in Taurus, in fall in Scorpio and in detriment in Capricorn. Ptolemy gives it a moist nature, and it is the chief of the nocturnal sect. Because it moves fastest of all the bodies, roughly thirteen degrees a day, it is the principal timekeeper of the classical system: it carries the applying and separating aspects on which horary judgment turns, and its position relative to the Sun defines the phases, which the tradition reads as a cycle of increase and decrease. Its natural significations are the mother in a night chart, the body, the common people, the household, liquids, and everything that changes, receives and reflects. In medical astrology it governs the humours and the flow of fluids, and in electional practice the phase of the Moon is one of the first things considered.

Ptolemy's Tetrabiblos explains the Moon's assigned quality on physical rather than merely traditional grounds, stating that she is chiefly humidifying because she stands nearest the earth and to the moist exhalations that rise from it, the same four-quality framework of hot, cold, wet and dry that classical medicine used to describe bodies and temperaments generally. That reasoning belongs to the Hellenistic synthesis of roughly the first century BCE to the second century CE in Greco-Roman Egypt, but the Moon's astrological importance is far older, rooted in Babylonian celestial omen-reading and horoscopy reaching back to perhaps 1000 BCE, where her monthly appearance, disappearance and eclipses were tracked for omens concerning the state long before Hellenistic astrology built the personal, chart-based system of phases and aspects now used to read an individual nativity.

Lunar Calendars and Lunar Deities

The synodic month of about twenty-nine and a half days is the basis of the lunar and lunisolar calendars used across the world, and the atlas records several: the Hebrew, Islamic, Hindu and Chinese systems each solve differently the problem that twelve lunar months fall about eleven days short of the solar year. The Islamic calendar simply lets the year drift; the Hebrew and Chinese insert intercalary months; the Hindu system does both in different regional forms. Lunar deities are as widespread as solar ones and are as often male as female, which is worth stating because the modern popular association of the Moon with the feminine is a generalisation that the historical record does not support: Sin and Nanna in Mesopotamia, Thoth and Khonsu in Egypt, Chandra and Soma in India, and Tsukuyomi in Japan are all male, while Selene, Luna, Artemis-Diana and Chang-e are female.

Two different months lie behind those calendars and confusing them is the commonest error in reading a lunar date. The synodic month, 29.53 days, is phase to phase, new moon to new moon, and it is what a lunar calendar counts. The sidereal month, 27.32 days, is the Moon's return to the same star, and it is what a nakshatra or mansion scheme counts. The difference of just over two days is the Sun's own movement during the month, which the Moon has to make up. The eleven day shortfall against the solar year resolves neatly at nineteen years: 235 synodic months come to within about two hours of 19 tropical years, the Metonic cycle, and it is that near coincidence the Hebrew and Chinese intercalation schemes exploit.

Glyph and Origin

Its glyph is a crescent. The Moon is one of the seven classical planets, watched and deified in ancient Mesopotamia and absorbed into Hellenistic astrology as a foundational body. As with the Sun's pairing to gold, alchemy assigned the Moon its own metal, silver, and the association is old enough to have left a mark on ordinary language: the Latin name for the Moon's day, dies Lunae, gives English Monday and the corresponding day in every Romance language, a naming pattern inherited from the same seven-day planetary week that fixed the classical glyphs in the first place.

The crescent sign travelled into modern computing with the rest of the classical set when Unicode encoded it in the Miscellaneous Symbols block in 1991, and it remains one of the few astrological glyphs whose modern printed form is essentially unchanged from its late antique original, unlike the Sun's circumpunct or Mercury's staff, both of which show real evolution across the Byzantine and medieval periods before settling into their present shapes. That stability may also owe something to necessity: because the Moon moves so quickly through the zodiac compared with the other classical bodies, its sign appears far more often in any working chart or ephemeris than most of its neighbours, and a mark that is drawn constantly has less room to drift than one consulted only rarely.

Correspondences & Relations

Exalted In

The Moon is exalted in Taurus, and the tradition reads the emotional nature at its most settled here - feelings that are steady and slow to disturb, an instinct for comfort, and a deep need for security and the reassurance of the senses. Astrologers describe a calm inner life that is hard to unsettle and equally hard to shift.

In Detriment In

The Moon is in its detriment in Capricorn, and the tradition reads a feeling nature that keeps itself in check - needs met through self-reliance rather than shown, emotions disciplined and held at a distance. Astrologers describe a reserved inner life that seeks security in structure and duty and is slow to admit its own wants.

In Fall In

The Moon is in its fall in Scorpio, and the tradition reads a feeling nature of great intensity that guards its depths - needs held secret, emotions that run to extremes, and attachments that are total. Astrologers describe a powerful inner life, slow to trust and slow to release, that transforms through what it feels most deeply.

Placed in House

With the Moon in the tenth house the emotional life is exposed to public view, and astrologers read a person whose feelings and need to nurture are expressed through career and reputation. The tradition notes a standing that fluctuates, a responsiveness to the public mood, and often a vocation of care.

The Moon in the eleventh house seeks emotional belonging in friendship and the group, and astrologers read a person who treats friends as family and whose feelings are engaged by shared hopes. The tradition notes comfort found in community and a nurturing instinct extended to the collective.

With the Moon in the twelfth house the feelings withdraw into the hidden, and astrologers read a rich, private emotional life easily overwhelmed by the world and in need of retreat. The tradition notes deep compassion, unspoken needs, and moods drawn from sources below the surface.

Astrologers read the Moon in the first house as a feeling nature worn openly - moods visible in the manner, a presence that responds to and reflects the emotional weather around it. The tradition notes sensitivity, changeability, and a self met first through its receptivity.

With the Moon in the second house emotional security is tied to material security, and astrologers read a person who needs the reassurance of resources and comfort to feel safe. The tradition notes fluctuating finances and a habit of seeking in possessions the steadiness the feelings crave.

The Moon in the third house colours thought and speech with feeling, and astrologers read a mind that needs to talk through its moods and stays close, emotionally, to siblings and the immediate surroundings. The tradition notes a changeable, impressionable intelligence and comfort found in familiar exchange.

The Moon in the fifth house ties the feelings to pleasure, romance and children, and astrologers read a person whose emotional life is expressed through play and creativity and who loves warmly and demonstratively. The tradition notes moods bound up with the joys of self-expression and a tender devotion to children.

With the Moon in the sixth house emotional wellbeing is tied to the daily round, and astrologers read a person who nurtures through work and service and whose moods register in the body and health. The tradition notes comfort found in useful routine and a tendency for feeling to affect the constitution.

The Moon in the seventh house seeks emotional security in partnership, and astrologers read a person who needs a close relationship to feel settled and is drawn to nurturing or to being nurtured. The tradition notes a strong instinct for union and a domestic warmth carried into marriage.

With the Moon in the eighth house the feelings run deep and hidden, and astrologers read an intense emotional nature drawn to intimacy, crisis and what is shared or concealed. The tradition notes powerful attachments, emotional extremes, and a capacity to be transformed through what is felt most privately.

The Moon in the ninth house ties feeling to belief and the far horizon, and astrologers read an emotional need for meaning, movement and the foreign. The tradition notes moods lifted by travel and philosophy and an instinctive rather than reasoned faith.

Placed in Sign

With the Moon in Aquarius the feelings are held at a cool remove, and astrologers read an inner life that meets its needs through friendship, ideals and independence rather than through intimacy alone. The tradition notes emotions understood before they are felt and a comfort found in belonging to something larger than the personal.

Astrologers read the Moon in Aries as a feeling nature that reacts fast and without disguise - needs pressed immediately, moods that flare and pass, an instinct to meet emotion with action. The tradition notes courage and impatience in the inner life and comfort found in independence rather than in being tended.

With the Moon in Gemini the feelings are filtered through the mind, and astrologers read an inner life that talks itself through its moods and needs variety to feel at ease. The tradition notes changeable, curious emotions and a habit of meeting need with words and understanding rather than with quiet.

Astrologers read the Moon in Leo as a warm and demonstrative feeling nature that needs to be loved openly and answers coldness with hurt pride. The tradition notes generous, steady affections, a dramatic inner life, and an instinct to give warmth and to command it in return.

The Moon in Libra ties emotional wellbeing to harmony, and astrologers read a nature that needs relationship and peace to feel settled and is unbalanced by discord. The tradition notes a gracious, accommodating inner life that reaches for another to steady itself and dislikes being at odds.

The Moon in Pisces dissolves the edge of feeling, and the tradition reads an inner life of great sympathy that absorbs the moods of everything around it. Astrologers describe boundless, compassionate emotions, a need for retreat and imagination, and a nature that can lose its own needs in another's.

With the Moon in Sagittarius the emotional nature needs room and a reason to hope, and astrologers read an inner life that is restless when confined and buoyed by movement, belief and the open view. The tradition notes warm, frank feelings and a comfort found less in settling than in seeking.

With the Moon in Virgo the feelings seek order, and astrologers read an inner life that tends its needs through usefulness, routine and care of detail. The tradition notes emotions kept modestly in check, a tendency to worry, and comfort found in being helpful and in things done properly.

Rules the House

With the Moon in the fourth house it rests in a domain close to its own nature, and astrologers read deep emotional roots in home and family - a powerful need for a private base and a strong bond to origin and memory. The tradition notes an inner life that is the emotional foundation of the whole chart.

Rules the Sign

In Cancer the Moon rules its own sign, and the tradition reads the emotional nature undiluted - deep, tidal feeling, a powerful instinct to nurture and protect, and needs bound up with home, family and memory. Astrologers describe an inner life of great receptivity, strongly attuned to the moods around it.

Worshipped As

Arianrhod's name means silver wheel, and her fortress Caer Arianrhod was identified with a constellation rather than with the moon. The lunar reading is a twentieth century neopagan development, not anything found in the Mabinogi.

Chandra, also called Soma, is the second graha, and the Indian calendar is lunisolar, so the moon carries more structural weight in jyotisha than in Western practice. The Moon's sign, not the Sun's, grounds a typical Indian reading.

Chang e fled to the moon after taking the elixir of immortality and remains its best known occupant, with the Mid-Autumn Festival still addressed to her. Chinese astronomy treated the moon as Yue, a body rather than a person.

Khonsu is a genuine Egyptian lunar god whose name is read as traveller, describing the moon's passage. Thoth also carried lunar functions, so Egyptian practice divided the moon between two gods rather than settling on one.

Luna is simply the Latin word for the moon treated as a goddess, used where the Greeks used Selene. The word survives in the lunar vocabulary of astrology and in the ordinary speech of the Romance languages.

Mani steers the moon in Norse cosmology and is Sol's brother, likewise pursued by a wolf. Monday carries his name into English through the Germanic translation of the Roman planetary week, which is the real mechanism here.

Metztli is the Nahuatl moon, and the Mexica read a rabbit rather than a face in its markings, an image shared with East Asia. Coyolxauhqui, dismembered by Huitzilopochtli, carries the moon's mythic role more prominently.

Selene is the moon as body rather than as huntress, and Greek practice kept her distinct from Artemis, who acquired lunar associations later. Hellenistic astrology inherited the lunar planet under Selene's name from Babylonian precedent.

Sin of Ur was the moon itself in Babylonian reckoning rather than merely its patron, and the lunar month governed the Mesopotamian calendar. This is the source layer from which the later Greek and Roman moon deities were mapped.

Tsukuyomi is the moon kami born from Izanagi's right eye as Amaterasu was born from the left, and their estrangement in myth explains why sun and moon never share the sky. Monday, Getsuyobi, carries the same character.
