(It. Ant. p. 230; It. Hier. p. 569; in Geog. Rav. 4.6, Tarpodizon), a town in the E. of Thrace, on the road from Byzantium to Anchialus.
According to Kiepert, its site answers to that of the modern Bojuk-Derbend;
according to Reichard, to that of Kodsje-Tarla;
according to Lapie, to that of Dewlet-Agatch.
But in some maps it is placed nearly due south of Sadame, and on or near the river Artiscus: if this is correct, Tarpodizus must have been in the neighbourhood of Erekli.
