Woman's mysterious bleedings in time with moon cycles were first seen as the human embodiment of the cosmic mysteries of birth, death and rebirth and served as the basis for time-keeping. With the rise of absolute kingships in the Ancient Near East, authority shifted from women and goddesses to men and gods. The male sun displaced the cycling moon as dominant deity. This conflict between the moon and sun estranged women from the cosmic dance and led to their social marginalization. Spiritual imagery became solar, an exclusive and masculine imagery recognizing only one truth and demonizing all else. Incorporated into Judaism and Christianity, this imagery became an integral part of Western culture.The history of the Jewish and Christian calendars show how women were excluded from time-keeping, further marginalizing them. This eliminated the natural world from time-keeping, adding to our alienation from nature.To end the Battle between the Moon and Sun a new spiritual imagery must replace the current solar form. The history of the Battle shows that redeveloping the old female lunar imagery could help restore social inclusiveness and a reverence for life.
