Pausanias, Description of Greece 9. 38. 8 (trans. Jones) (Greek travelogue C2nd A.D.) :
"The town [Aspledon in Boiotia] got its name from Aspledon, who was a son of the Nymphe Mideia and Poseidon. Their view is confirmed by some verses composed by Khersias (Chersias), a man of Orkhomenos (Orchomenus) :--‘To Poseidon and glorious Mideia was born Aspledon in the spacious city’ . . . Originally this city stood on high ground and was called Mideia after the mother of Aspledon."
