Aidoneus (Gr. Ἀїδωνεύς) was a mythical king of the Molossians in Epirus, who is represented as the husband of Persephone. After Theseus, with the assistance of Pirithous, concealed Helen at Aphidnae, he went to Epirus to procure for Pirithous Kore, the daughter of Aidoneus, as a reward. When Aidoneus discovered that they had come with the intention of carrying off his daughter, he had Pirithous killed by Cerberus, and kept Theseus in captivity, who was afterwards released at the request of Heracles.Eusebius calls the wife of Aidoneus a daughter of queen Demeter, with whom he had eloped. Thus the story of Aidoneus is the legend of Hades' rape of Persephone, in the form of a real-world history, and is undoubtedly the work of a late interpreter of ancient myths.
