Autonoe was the daughter of King Cadmus of Thebes and the goddess Harmonia, in Greek mythology. She was married to Aristaeus, and had two children, Actaeon and Macris. She was a follower of the god Dionysus, who was her nephew; when she and the other believers were banned from worshipping their god by King Pentheus, Dionysus drove them into a frenzy, during which they killed Pentheus. Her son, Actaeon, was a capable hunter, who was torn to pieces by his hounds, punished for seeing the goddess Artemis naked.
