The Moon

From the Latin 'luna'. The name is straightforward, but the card carries a long freight of lunar symbolism — the moon as the ruler of tides, dreams, illusions, and the uncertain path between waking and sleeping.

From the Marseille tradition onward the image is remarkably stable: a moon bearing a human face hangs in the sky, shedding dew-like drops. Two towers stand on either side, two beasts — dogs or a dog and a wolf — bay at the moon, and a crayfish or lobster crawls from the water along a winding path.

Smith sharpened the inherited image. A full moon with a brooding human face drops clear drops of dew, two towers flank a path that winds between them into the distance, two dogs howl, and a large crayfish emerges from a pool in the foreground. The landscape is nocturnal and uneasy.

The moonlit face is the unconscious and its flickering, deceptive light. The two towers mark the threshold of the known world; the two dogs are the tame and wild instincts aroused by the moon. The crayfish rising from the deep is the primitive fear and the archaic content climbing toward awareness. The Moon is the path through illusion, walked before the clarity of dawn.

The Marseille and Waite images are closely aligned, with Smith mainly intensifying the detail and mood. In the Thoth deck Crowley unites crescent and full moon, places the scarab Khepri at the bottom, and adds Anubis and a jackal flanking the lunar path, layering Egyptian solar-lunar mythology onto the image.

The card draws on Diana, Hecate, and Sin — lunar deities of the threshold and the underworld — and on the albedo phase of alchemy, the whitening that follows the dark work. Astrologically it corresponds to Pisces. As trump number 18 it is the nocturnal passage after the Star's hope: the trial of walking by uncertain light before the Sun's full clarity.
