Lyco and Orphe

Lyco and Orphe (Λυκώ καὶ Ὄρφη) are two sisters from Greek mythology. Their story survives in the works of Maurus Servius Honoratus, a Latin grammarian of the early fifth century AD.

Family
They were the daughters of Amphithea and Dion, the queen and king of Laconia. They had a third sister named Carya.

Mythology
Once Apollo, the god of prophecy, paid a visit to Dion and his family. He was so well-received that he gave all three of Dion's daughters the gift of prophecy, under the condition that they would never betray the gods or seek after forbidden things. Later, Dionysus visited the family and fell in love with Carya, so that he visited again in order to see her. But Lyco and Orphe guarded Carya, and tried to prevent Dionysus from wooing her. Dionysus then reminded them of their promise to Apollo, and drove them mad. As the two sisters reached the top of Mount Taygetus in their raging madness, they were transformed into rocks.
