Rhea

Titaness, daughter of Earth and Heaven, wife of Cronus and mother of Hestia, Demeter, Hera, Hades, Poseidon and Zeus; seized by "unceasing grief" as each was swallowed, she sought her parents' counsel and bore Zeus in Crete. Homer has her hand the infant Hera to Oceanus and Tethys; the Hymn to Demeter makes her Zeus's envoy to her daughter.
