Before they became symbols of evil, lust and deceit, associated with the biblical fall of man in the Garden of Eden, snakes were ancient symbols of divine female wisdom, regeneration, healing and immortality. They were associated with the moon, which sloughs its shadow as it wanes and waxes – just as the snake sheds its skin. And because the lunar cycle was taken to match the life-giving menstrual cycle of the womb (another cycle of shedding and regeneration), snakes also symbolised fertility and birth.
