The ancient Goddesses of Nature ruled the world since its creation till ca. 2000-1000 B.C.E., when they were slowly replaced by male deities. They were goddesses of birth, growth, and death, assimilated to the three phases of the Moon —waxing, full, and waning—.

This site attempts to provide scientific information about the history of Goddesses and the development of female rôle and sexuality through Indo-European times and Christianity.
