By the 4th century BC it had grown in importance and included a theatre, a sanctuary to Asclepius and an agora.
A room in Pyrrhus's palace at Buthrotum; an antechamber separating the apartments of Titus and Bérénice in Rome; Agamemnon's camp at Aulis; an antechamber in the temple at Jerusalem: by choosing such vague and remote settings Racine gives his plays a universal character, and the presentation of conflicting and hesitating states of mind is not hampered by an undue insistence on material surroundings.
It is thus that the see appears in the sources from the 9th century on as "Nafpaktos of Nicopolis" (μητρόπολις Ναυπάκτου Νικοπόλεως), counting initially eight suffragans covering all of Epirus: Vonditsa, Aetos, Acheloos, Rogoi, Ioannina, Photiki, Hadrianopolis, Buthrotum.
