AUTONOE
a daughter of Cadmus and Harmonia, was the wife of Aristaeus, by whom she became the mother of Polydorus. (Theogony of Hesiod 977) According to Apollodorus (Apollodorus iii), Polydorus was a brother of Autonoe, and Actaeon was her son.
Autonoe together with her sister Agave tore Pentheus to pieces in their Bacchic fury.
At last grief and sadness at the lamentable fate of the house
of her father induced her to quit Thebes, and she went to Erineia
in the territory of Megara, where her tomb was shewn as late as
the time of Pausanias.
