It was lunar symbolism that enabled man to relate and connect such heterogeneous things as: birth, becoming, death, and resurrection; the waters, plants, woman, fecundity, and immortality; the cosmic darkness, prenatal existence, and life after death, followed by the rebirth of the lunar type ("light coming out of darkness"); weaving, the symbol of the "thread of life," fate, temporality, and death; and yet others. In general most of the ideas of cycle, dualism, polarity, opposition, conflict, but also of reconciliation of contraries, of coincidental oppositorum, were either discovered or clarified by virtue of lunar symbolism. We may even speak of a metaphysics of the moon, in the sense of a consistent system of "truths" relating to the mode of being peculiar to living creatures, to everything in the cosmos that shares in life, that is, in becoming, growth and waning, death and resurrection.
