Antiquarian celestial illustration of the planet Moon

The lunar luminary in historical planetary correspondence systems.

Overview

The Moon is the changing luminary of the classical planetary order, long observed through phases, tides of light, and nightly motion. Ptolemy describes it as moist and moderately warm, benefic, and ruler of Cancer. Renaissance and Solomonic sources connect it with water and earth, lunar plants and stones, Monday, silver, and argentine color.

Historical and Astrological Context

The Moon’s visible phases made it a natural measure of change, return, and nocturnal time. Historical astrology counts it among the seven planets because “planet” there means a wandering celestial light. The database also holds modern phase records, but a phase-to-intention convention is not silently promoted into a direct Moon-to-intention claim.

Traditional and Modern Rulerships

Ptolemy assigns Cancer to the Moon in Book I, Chapter XX. This classical domicile remains distinct from modern lunar-phase conventions and from divine figures whose identities cannot be reduced to the astronomical Moon.

Traditional Qualities

Ptolemy gives the Moon a chiefly moist influence with moderate warmth and classifies it among the benefics. These terms belong to classical astrology and are not statements about the Moon’s geological surface or temperature.

Plants, Stones, Metals, and Ritual Materials

Agrippa’s lunar correspondences include water and earth, rosemary, olive, palm, rock crystal, and historically identified beryl. The Key of Solomon connects the Moon with Monday, silver, and an argentine color. Uncertain historical stone names retain their cautions.

Modern Practice

Modern lunar practice commonly attends to waxing, fullness, waning, and darkness as distinct ritual times. Mystic keeps those phase relationships non-default and source-scoped so that modern convention does not overwrite the historical planetary layer.

Safety and Physical Boundaries

Planetary records describe symbolic and historical relationships. They do not authorize ingestion, burning, topical use, or handling of connected materials. Each physical entity carries its own safety review, and hazardous records are excluded from default ritual candidates.
