21. Next to the Sea of Sicily, are the Cretan, Saronic,[812] and Myrtoan Seas, comprised between Crete, Argia,[813] and Attica.[814] Their greatest breadth, measured from Attica, is 1200 stadia, and their length not quite double the distance. Within are included the Islands of Cythera,[815] Calauria,[816] Ægina,[817] Salamis,[818] and certain of the Cyclades.[819] Adjacent to these are the Ægæan Sea,[820] the Gulf of Melas,[821] the Hellespont,[822] the Icarian and Carpathian Seas,[823] as far as Rhodes, Crete, Cnidus, and the commencement of Asia. [In these seas] are the Cyclades, the Sporades, and the islands opposite Caria, Ionia, and Æolia, as far as the Troad, namely, Cos,[824] Samos,[825] Chios,[826] Lesbos,[827] and Tenedos;[828] likewise on the Grecian side as far as Macedonia and the borders of Thrace, Eubœa,[829] Scyros,[830] Peparethus,[831] Lemnos,[832] Thasos,[833] Imbros,[834] Samothracia,[835] and numerous others, of which it is our intention to speak in detail. The length of this sea is about 4000 stadia, or rather more,[836] its breadth about 2000.[837] It is surrounded by the coast of Asia above mentioned, and by those of Greece from Sunium[838] northwards to the Thermaic Gulf[839] and the Gulfs of Macedonia,[840] and as far as the Thracian Chersonesus.[841] 22. Here too is the strait, seven stadia in length, which is between Sestos[842] and Abydos,[843] and through which the Ægæan and Hellespont communicate with another sea to the north, named the Propontis,[844] and this again with another called the Euxine. This latter is, so to speak, a double sea, for towards its middle are two projecting promontories, one to the north, on the side of Europe, and the other opposite from the coast of Asia, which leave only a narrow passage between them, and thus form two great seas. The European promontory is named Criu-metopon;[845] that of Asia, Carambis.[846] They are distant from each other about 2500 stadia.[847] The length of the western portion of this sea[848] from Byzantium to the outlets of the Dnieper is 3800 stadia, its breadth 2000. Here is situated the Island of Leuca.[849] The eastern portion is oblong and terminates in the narrow recess in which Dioscurias is situated. In length it is 5000 stadia, or rather more, and in breadth about 3000. The entire circumference of the Euxine is about 25,000 stadia. Some have compared the shape of its circumference to a Scythian bow when bent, the string representing the southern portions of the Euxine, (viz. the coast, from its mouth to the recess in which Dioscurias is situated; for, with the exception of Carambis, the sinuosities of the shore are but trifling, so that it may be justly compared to a straight line,) and the remainder [of the circumference representing] the wood of the bow with its double curve, the uppermost very much rounded, the lower more in a straight line. So this sea forms two gulfs, the western much more rounded than the other.
