At the time of the cultural mother stage, the male and the female lived together in partnership. Both were safe in the maternal, in the great provide*ss who brought everything forth, took it back and brought it back again. This primordial mother, here in the picture as the birthing mother on the leopard throne, can still be found during patriarchal times in the Greek primordial mother Gaia. Here she is the primordial deity, the first and only one to emerge from chaos; as primordial mother she is the "Broad-chested Gaia", seat of all immortals the "Mother of all Gods".
Gaia - the mother of all gods
Gaia's importance in mythology as well as in cult lies mainly in the idea of the earth. From this idea, which was spread throughout all continents and over very long epochs, derives both Gaia's main meaning as Mother Goddess, who brings forth and nourishes all living things, and that of a Deity of Death, who takes man into her womb after his death. Delphi means "womb or uterus" and it was the famous oracle of Greece where Mother Earth was worshipped as the goddess Gaia and her snake dragon Phyton.
Gaia, the mother of all gods, was outshined by male gods as patriarchy progressed, whose power increasingly passed from father to son. According to Hesiod, the power of Uranos goes to his son Kronos and from him to his son Zeus, who is proclaimed to be the high god and father god of Olympus. Zeus therefore destroyed his own ancestors, sex of Titans, in a murderous battle and forcibly appropriated the creative power and the chthonic (earthly) powers, which until then had mainly been in the hands of great goddesses.
Patriarchization - the Disempowerment of Gaia
Zeus devoured the goddess of wisdom Metis when she got pregnant with her daughter Athena, and then let the goddess Athena arise from his head as a head birth. Behind the wisdom goddess Metis lies the ancient Egyptian goddess Maat and the Libyan snake goddess Medusa, both of whom represent female wisdom. Zeus devours them and thereby acquires the ability that is reserved only for mothers: He gives birth to Athenians, but out of his head because he lacks the life-giving maternal organs. This appropriation of the female natal act then finally lays the final psychological foundation for the justification of matricide and the taboo suppression of the cultural mother stage, which had determined the lives of humans on their life-giving mother over a period of at least 150,000 years.
