Hatzopoulos 2007, "Since only Hellenes participated in the Panhellenic sacrifices and contests, it is obvious that the theoroi visited only communities which considered themselves and were considered by the others as Greek. [...] Similarly the [theorodokoi] section Epirus lists the states of Pandosia, Kassopa, Thesprotoi, Poionos, Korkyra, Chaonia, Artichia, Molossoi, Ambrakia, Argos (of Amphilochia). Of these the Elean colony of Pandosia and the Corinthian colonies of Korkyra and Ambrakia represent the southern Greek element, while Kassopa, the Thesprotoi, the Molossoi, Chaonia and Argos the "native" Epirote one. (Nothing is known of Poionos and Artichia). The important point is that colonial cities, Epirote cities and Epirote ethne, republican and monarchical alike, are considered equally Greek and invited to the great panhellenic sacrifices at Epidauros."
