Rhea

Rhea is the name of a Titan in Greek mythology, the mother of Zeus and several other Olympian gods. Her exact name meaning is uncertain; proposals connect it with flowing or with the ground. The mythological identity is much firmer than describing Rhea as a literal translation of a flowing stream.

Rheia is another rendering of the ancient name, while Rea simplifies the spelling. English pronunciation can begin like either ree or ray, so the preferred sound is worth sharing. Actress Rhea Perlman is a familiar bearer. The short written form carries an extensive mythological story without needing a longer name behind it.
