all men," says Herodotus, "they are ever ready to adopt the manners of the foreigners. They take from the Medes their robe, from the Egyptians their breastplate." Happy, if to the robe and the breastplate they had confined their appropriations from the nations they despised! Happy, if they had not imparted to their august religion the gross adulterations of the Median magi; if they had not exchanged their mild laws and restricted government, for the most callous contempt of the value of life [48] and the dignity of freedom. The whole of the pure Persian race, but especially the nobler tribe of the Pasargadae, became raised by conquest over so vast a population, to the natural aristocracy of the land. But the valuable principle of aristocratic pride, which is the safest curb to monarchic encroachment, crumbled away in the atmosphere of a despotism, which received its capricious checks or awful chastisement only in the dark recesses of a harem. Retaining to the last their disdain of all without the Persian pale; deeming themselves still "the most excellent of mankind;" [49] this people, the nobility of the East, with the arrogance of the Spartan, contracting the vices of the Helot, rapidly decayed from all their national and ancient virtues beneath that seraglio-rule of janizaries and harlots, in which, from first to last, have merged the melancholy destinies of Oriental despotism. VII. Although Darius seems rather to have possessed the ardour for conquest than the genius for war, his reign was memorable for many military triumphs, some cementing, others extending, the foundations of the empire. A formidable insurrection of Babylon, which resisted a siege of twenty-one months, was effectually extinguished, and the new satrap government, aided by the yearly visits of the king, appears to have kept from all subsequent reanimation the vast remains of that ancient empire of the Chaldaean kings. Subsequently an expedition along the banks of the Indus, first navigated for discovery by one of the Greeks whom Darius took into his employ, subjected the highlands north of the Indus, and gave that distant river as a new boundary to the Persian realm. More important, had the fortunes of his son been equal to his designs, was the alarming settlement which the monarch of Asia effected on the European continent, by establishing his sovereignty in Thrace and Macedonia--by exacting homage from the isles and many of the cities of Greece--by breaking up, with the crowning fall of Miletus, the independence and rising power of those Ionian colonies, which ought to have established on the Asiatic coasts the permanent barrier to the irruptions of eastern conquest. Against these successes the loss of six thousand four hundred men at the battle of Marathon, a less number than Darius deliberately sacrificed in a stratagem at the siege of Babylon, would have seemed but a petty counterbalance in the despatches of his generals, set off, as it was,
