Walled towns serve thus as one of the evidences, that a large part of the population of Greece had, even in the Homeric times, reached a level higher than that of the Ætolians and Lokrians of the days of Thucydidês. The remains of Mykênæ and Tiryns demonstrate the massy and Cyclopian style of architecture employed in those early days: but we may remark that, while modern observers seem inclined to treat the remains of the former as very imposing, and significant of a great princely family, Thucydidês, on the contrary, speaks of it as a small place, and labors to elude the inference, which might be deduced from its insignificant size, in disproof of the grandeur of Agamemnôn.[197] Such fortifications supplied a means of defence incomparably superior to those of attack. Indeed, even in historical Greece, and after the invention of battering engines, no city could be taken except by surprise or blockade, or by ruining the country around, and thus depriving the inhabitants of their means of subsistence. And in the two great sieges of the legendary time, Troy and Thêbes, the former is captured by the stratagem of the wooden horse, while the latter is evacuated by its citizens, under the warning of the gods, after their defeat in the field. [197] Thucyd. i. 10. Καὶ ὅτι μὲν Μυκῆναι μικρὸν ἦν, ἢ εἴ τι τῶν τότε πόλισμα νῦν μὴ ἀξιόχρεων δοκεῖ εἶναι, etc. This decided superiority of the means of defence over those of attack, in rude ages, has been one of the grand promotive causes both of the growth of civic life and of the general march of human improvement. It has enabled the progressive portions of mankind not only to maintain their acquisitions against the predatory instincts of the ruder and poorer, and to surmount the difficulties of incipient organization,—but ultimately, when their organization has been matured, both to acquire predominance, and to uphold it until their own disciplined habits have in part passed to their enemies. The important truth here stated is illustrated not less by the history of ancient Greece, than by that of modern Europe during the Middle Ages. The Homeric chief, combining superior rank with superior force, and ready to rob at every convenient opportunity, greatly resembles the feudal baron of the Middle Ages, but circumstances absorb him more easily into a city life, and convert the independent potentate into the member of a governing aristocracy.[198] Traffic by sea continued to be beset with danger from pirates, long after it had become tolerably assured by land: the “wet ways” have always been the last resort of lawlessness and violence, and the Ægean, in particular, has in all times suffered more than other waters under this calamity.
