The coins, which begin in the fourth century BC, bear the name Apollonia and the image of Apollo; the imperial coins, which continue to the first half of the third century AD, and the Tabula Peutinger also contain the name Apollonia; but the "Periplus Ponti Euxini", 85, and the Notitiæ episcopatuum have only the new name Sozopolis. In 1328 Cantacuzene (ed. Bonn, I, 326) speaks of it as a large and populous town.
