Speaker, Reciter (rhêtos)
RHETIA was an Oreiad-nymph of Mount Saon on the north Aegean island of Samothrake. She was the mother by Apollon of the nine Samothrakian Korybantes (Corybantes)--orgiastic dancers of the Mysteries. Rhetia was probably the goddess who presided over the recitation of the lore of the Mysteries to the new initiates.
Rhetia was probably associated with the Mousai (Muses), two of whom are named as the mother of the Samothrakian Korybantes in alternate genealogies. Her name means "Reciter" or "Speaker" which also suggests a Mousa.
