RHEA

(Rheidae; Ϯ Greater Rhea R. americana) Gr. myth. Rhea, daughter of Gaia and Uranus, and mother to Zeus and the gods  < ῥεω rheō  to flow, because rivers flow from Earth (γαια gaia  Earth). The relevance of this epithet is unknown, although it may reflect the humorous juxtaposition of Rhea, the Great Mother, with the Ostrich, the Great Bird, in Aristophanes’ comedy Ornithes (The Birds). Valdés Chadwick 2016, recalls the myth of Cronon and Rhea, his sister and wife. Troubled by prophecy Cronon devoured his new-born children, with the exception of Zeus whom Rhea replaced with a stone wrapped in swaddling clothes. Cronon swallowed the offering, and, by association, it is noted that rheas, and other struthious birds, swallow stones and pebbles as an aid to digestion. "Amerikaanse Struis.
