Cults Myths and Legends of Ancient Sicily
5.1 Cults and Minor Myths: Rea
According to Greek mythology Rhea was the daughter of Gaia and Uranus, she married Cronos with whom she had six children: Estia, Demeter, Hera, Hades, Poseidon, Zeus. Hera was therefore considered the parent of the entire lineage of the Olympic gods and for this reason she was given the nickname of Great Mother or Mother of the Gods. With the same name she was also called Cybele, a non-Greek divinity of Asia Minor. When the Asian cult merged with the Greek one, Rea was identified with Cybele, and it is with this last name that she was known in the West and, therefore, also in Sicily.
