In this manner is the third great Gulf of Europe bounded. The mountains of Thrace, besides those already mentioned, are Edonus, Gigemoros, Meritus, and Melamphyllos; the rivers are the Bargus and the Syrmus, which fall into the Hebrus. The length of Macedonia, Thrace, and the Hellespont has been already[2590] mentioned; some writers, however, make it 720 miles, the breadth being 384. What may be called a rock rather than an island, lying between Tenos and Chios, has given its name to the Ægean Sea; it has the name of Æx[2591] from its strong resemblance to a goat, which is so called in Greek, and shoots precipitately from out of the middle of the sea. Those who are sailing towards the isle of Andros from Achaia, see this rock on the left, boding no good, and warning them of its dangers. Part of the Ægean Sea bears the name of Myrtoan[2592], being so called from the small island [of Myrtos] which is seen as you sail towards Macedonia from Geræstus, not far from Carystus[2593] in Eubœa. The Romans include all these seas under two names,—the Macedonian, in those parts where it touches the coasts of Macedonia or Thrace, and the Grecian where it washes the shores of Greece. The Greeks, however, divide the Ionian Sea into the Sicilian and the Cretan Seas, after the name of those islands; and they give the name of Icarian to that part which lies between Samos and Myconos. The gulfs which we have already mentioned, have given to these seas the rest of their names. Such, then, are the seas and the various nations which are comprehended in the third great Gulf of Europe. CHAP. 19. (12.)—THE ISLANDS WHICH LIE BEFORE THE LANDS ALREADY MENTIONED. Lying opposite to Thesprotia, at a distance of twelve miles from Buthrotus, and of fifty from Acroceraunia, is the island of Corcyra[2594], with a city of the same name, the citizens of which are free; also a town called Cassiope[2595], and a temple dedicated to Jupiter Cassius. This island is ninety-seven miles in length, and in Homer has the names of Scheria and Phæacia; while Callimachus calls it Drepane. There are some other islands around it, such as Thoronos[2596], lying in the direction of Italy, and the two islands of Paxos[2597] in that of Leucadia, both of them five miles distant from Corcyra. Not far[2598] from these, and in front of Corcyra, are Ericusa, Marathe, Elaphusa, Malthace, Trachie, Pythionia, Ptychia, Tarachie, and, off Phalacrum[2599], a promontory of Corcyra, the rock into which (according to the story, which arises no doubt from the similarity of appearance) the ship of Ulysses was changed.
