The Moon is the second of the two great luminaries and the complement of the Sun. Sources differ on the Moon's nature: in the exoteric myths told openly the Moon is the wife of the Sun and the maker of women, bound to menstrual blood and female fertility; in the esoteric versions held by the shaman-masters the Moon is instead the Sun's younger brother, a second male power. Cold and wet where the Sun is hot and dry, the Moon governs the damp pole of the cosmos; when it comes too close to the earth the world grows cold and sodden, and the interplay of the two luminaries determines the seasons and the success or failure of the gardens. Women are said to issue from the Moon as men issue from the Sun.
