Great Mother of the Gods, in ancient Middle Eastern religion (and later in Greece, Rome, and W Asia), mother goddess, the great symbol of the earth's fertility. As the creative force in nature she was worshiped under many names, including Astarte (Syria), Ceres (Rome), Cybele (Phrygia), Demeter (Greece), Ishtar (Babylon), and Isis (Egypt). The later forms of her cult involved the worship of a male deity (her son or lover, e.g., Adonis, Osiris), whose death and resurrection symbolized the regenerative power of the earth.
Gaea, in Greek mythology, the earth; daughter of Chaos, mother and wife of both Uranus (the sky) and Pontus (the sea). She was mother, by Uranus, of the Cyclopes, the Titans, and others, and, by Pontus, of five sea deities. She helped cause the overthrow of Uranus by the Titans and was worshiped as the primal goddess, the mother of all things.
Uranus, in Greek mythology, the heavens, first ruler of the universe; son and husband of Gaea; father of Titans, Cyclops, and Hundred-handed Ones. Uranus was castrated and dethroned by Cronus. His blood, falling onto Earth, produced the vengeful Furies; from his discarded flesh and the sea Aphrodite arose.
