The sea which divides Greece from Italy is contracted, between the Iapygian peninsula and the coast of Epirus, into a channel only thirty geographical miles in breadth; and the Italian coast may be seen not only from the mountains of Corcyra, but from the low headland of the Ceraunian hills. Thus on two sides Greece is bounded by a narrow sea; but towards the north its limits were never precisely defined. The word Hellas did not convey to the Greeks the notion of a certain geographical surface, determined by natural or conventional boundaries: it denoted the country of the Hellenes, and was variously applied according to the different views entertained of the people which was entitled to that name. The original Hellas was included in the territory of a little tribe in the south of Thessaly. When these Hellenes had imparted their name to other tribes, with which they were allied by a community of language and manners, Hellas might properly be said to extend as far as these national features prevailed. On the east, Greece was commonly held to terminate with Mount Homole at the mouth of the Peneus; the more scrupulous, however, excluded even Thessaly from the honour of the Hellenic name, while Strabo,[f] with consistent laxity, admitted Macedonia. But from Ambracia to the mouth of the Peneus, when these were taken as the extreme northern points, it was still impossible to draw a precise line of demarcation; for the same reason which justified the exclusion of Epirus applied, perhaps much more forcibly, to the mountaineers in the interior of Ætolia, whose barbarous origin, or utter degeneracy, was proved by their savage manners, and a language which Thucydides[g] describes as unintelligible. When the Ætolians bade the last Philip withdraw from Hellas, the Macedonian king could justly retort, by asking where they would fix its boundaries, and by reminding them that of their own body a very small part was within the pale from which they wished to exclude him.
