From Doriscus there is a winding coast as far as Macron Tichos[2538], or the “Long Wall,” a distance of 122 miles; round Doriscus flows the river Melas, from which the Gulf of Melas[2539] receives its name. The towns are, Cypsela[2540], Bisanthe[2541], and Macron Tichos, already mentioned, so called because a wall extends from that spot between the two seas,—that is to say, from the Propontis to the Gulf of Melas, thus excluding the Chersonesus[2542], which projects beyond it. The other side of Thrace now begins, on the coast[2543] of the Euxine, where the river Ister discharges itself; and it is in this quarter perhaps that Thrace possesses the finest cities, Histropolis[2544], namely, founded by the Milesians, Tomi[2545], and Callatis[2546], formerly called Acervetis. It also had the cities of Heraclea and Bizone, which latter was swallowed up by an earthquake; it now has Dionysopolis[2547], formerly called Cruni, which is washed by the river Zyras. All this country was formerly possessed by the Scythians, surnamed Aroteres; their towns were, Aphrodisias, Libistos, Zygere, Rocobe, Eumenia, Parthenopolis, and Gerania[2548], where a nation of Pigmies is said to have dwelt; the barbarians used to call them Cattuzi, and entertain a belief that they were put to flight by cranes. Upon the coast, proceeding from Dionysopolis, is Odessus[2549], a city of the Milesians, the river Panysus[2550], and the town of Tetranaulochus. Mount Hæmus, which, with its vast chain, overhangs the Euxine, had in former times upon its summit the town of Aristæum[2551]. At the present day there are upon the coast Mesembria[2552], and Anchialum[2553], where Messa formerly stood. The region of Astice formerly had a town called Anthium; at the present day Apollonia[2554] occupies its site. The rivers here are the Panisos, the Riras, the Tearus, and the Orosines; there are also the towns of Thynias[2555], Halmydessos[2556], Develton[2557], with its lake, now known as Deultum, a colony of veterans, and Phinopolis, near which last is the Bosporus[2558]. From the mouth of the Ister to the entrance of the Euxine, some writers have made to be a distance of 555 miles; Agrippa, however, increases the length by sixty miles. The distance thence to Macron Tichos, or the Long Wall, previously mentioned, is 150 miles; and, from it to the extremity of the Chersonesus, 126.
