Stephanos of Byzantium - Ethnika
Delphoi: a city on Parnassos near Phokis, where the inner sanctuary was built of Pentelic stone, the work of Agamedes and Trophonios. There is also a fountain in the place called 'Delphoussa'. The ethnonym has the same name as the city; the feminine is 'Delphis', and the possessive adjective is 'Delphikos'. They were called 'Delphoi' because Apollo sailed alongside in the likeness of a dolphin; a sanctuary has also been established for Apollo. There is also Delphousia, a city in Arkadia, as per Androtion in book 2 of his Atthis. The ethnonym is 'Delphousiates', formed on the pattern used for a region.
