In Greek mythology, the Thriae ("pebbles"; also Thriai) were three virgin sisters. They were nature goddesses who were able to see the future (a trick learned from Hermes) and interpret the signs of nature and omens (such as tossing pebbles, the source of their name). They lived near Mount Parnassus.
In art, they were old, winged and silver-haired (covered in white flour). They bear a resemblance to bees covered with pollen.
Thriae are three Greek, holy sisters who are virgins.
They recieved their name, Thriae, because they are lesser goddesses of nature who can foresee the future or foretell the unknown by inspiration, magic, signs, or omens.
They live under a ridge of Mt. Parnassus, and the word Thriae means "pebbles," because the future was foretold by tossing pebbles.
