The daughter of king Pandion of Athens and Zeuxippe. She was the wife of Tereus and by him the mother of Itys. After Tereus raped her sister Philomela, Procne killed their son Itys and served the boy for dinner to him. When he realized whom he had eaten, the enraged Tereus pursued Procne and her sister, but the gods intervened and turned them all into birds; Procne was turned into a swallow.
