The Thriae (//; Ancient Greek: θριαί Thriaí) were nymphs, three virginal sisters, one of a number of such triads in Greek mythology. They were named Melaina ("The Black"), Kleodora ("Famed for her Gift"), and Daphnis ("Laurel") or Corycia. They were the three Naiads (nymphs) of the sacred springs of the Corycian Cave of Mount Parnassus in Phocis, and the patrons of bees. The nymphs had heads like women and lower body with wings like a bee.
These three bee maidens with the power of divination and thus speaking truth are described in Homer's Hymn to Hermes, and the food of the gods is "identified as honey"; the bee maidens were originally associated with Apollo, and are probably not correctly identified with the Thriae. Both the Thriae and the Bee Maidens are credited with assisting Apollo in developing his adult powers, but the divination that Apollo learned from the Thriae differs from that of the Bee Maidens. The type of divination taught by the Thriae to Apollo was that of mantic pebbles, the throwing of stones, rather than the type of divination associated with the Bee Maidens and Hermes: cleromancy, the casting of lots. Honey, according to a Greek myth, was discovered by a nymph called Melissa ("Bee"); and honey was offered to the Greek gods from Mycenean times. Bees were associated, too, with the Delphic oracle and the prophetess was sometimes called a bee.
