Eubœa[2672] itself has also been rent away from Bœotia; the channel of the Euripus, which flows between them, being so narrow as to admit of the opposite shores being united by a bridge[2673]. At the south, this island is remarkable for its two promontories, that of Geræstus[2674], which looks towards Attica, and that of Caphareus[2675], which faces the Hellespont; on the north it has that of Cenæum[2676]. In no part does this island extend to a greater breadth than forty miles, while it never contracts to less than two. In length it runs along the whole coast of Bœotia, extending from Attica as far as Thessaly, a distance of 150 miles[2677]. In circumference it measures 365, and is distant from the Hellespont, on the side of Caphareus, 225 miles. The cities for which it was formerly famous were, Pyrrha, Porthmos, Nesos, Cerinthos[2678], Oreum, Dium, Ædepsos[2679], Ocha, and Œchalia; at present it is ennobled by those of Chalcis[2680] (opposite which, on the mainland, is Aulis), Geræstus[2681], Eretria[2682], Carystus[2683], Oritanum, and Artemisium[2684]. Here are also the Fountain of Arethusa[2685], the river Lelantus, and the warm springs known as Ellopiæ; it is still better known, however, for the marble of Carystus. This island used formerly to be called Chalcodontis and Macris[2686], as we learn from Dionysius and Ephorus; according to Aristides, Macra; also, as Callidemus says, Chalcis, because copper was first discovered here. Menæchmus says that it was called Abantias[2687], and the poets generally give it the name of Asopis. CHAP. 22.—THE CYCLADES.
