The considerable part played by the people of Greece during many ages must undoubtedly be ascribed to the geographical position of their country. Other tribes having the same origin, but inhabiting countries less happily situated—such, for instance, as the Pelasgians of Illyria, who are believed to be the ancestors of the Albanians—have never risen above a state of barbarism, whilst the Hellenes placed themselves at the head of civilised nations, and opened fresh paths to their enterprise. If Greece had remained for ever what it was during the tertiary geological epoch—a vast plain attached to the deserts of Libya, and run over by lions and the rhinoceros—would it have become the native country of a Phidias, an Æschylos, or a Demosthenes? Certainly not. It would have shared the fate of Africa, and, far from taking the initiative in civilisation, would have waited for an impulse to be given to it from beyond. {37} Greece, a sub-peninsula of the peninsula of the Balkans, was even more completely protected by transverse mountain barriers in the north than was Thracia or Macedonia. Greek culture was thus able to develop itself without fear of being stifled at its birth by successive invasions of barbarians. Mounts Olympus, Pelion, and Ossa, towards the north and east of Thessaly, constituted the first line of formidable obstacles towards Macedonia. A second barrier, the steep range of the Othrys, runs along what is the present political boundary of Greece. To the south of the Gulf of Lamia a fresh obstacle awaits us, for the range of the Œta closes the passage, and there is but the narrow pass of the Thermopylæ between it and the sea. Having crossed the mountains of the Locri and descended into the basin of Thebæ, there still remain to be crossed the Parnes or the spurs of the Cithæron before we reach the plains of Attica. The “isthmus” beyond these is again defended by transverse barriers, outlying ramparts, as it were, of the mountain citadel of the Peloponnesus, that acropolis of all Greece. Hellas has frequently been compared to a series of chambers, the doors of which were strongly bolted; it was difficult to get in, but more difficult to get out again, owing to their stout defenders. Michelet likens Greece to a trap having three compartments. You entered, and found yourself taken first in Macedonia, then in Thessaly, then between the Thermopylæ and the isthmus. But the difficulties increase beyond the isthmus, and Lacedæmonia remained impregnable for a long time.
