"When the Persians," says Herodotus, "saw the Athenians running down on them, without horse or bowmen, and scanty in numbers, they thought them a set of madmen rushing upon certain destruction." They began, however, to prepare to receive them and the Eastern chiefs arrayed, as quickly as time and place allowed, the varied races who served in their motley ranks. Mountaineers from Hyrcania and Affghanistan, wild horsemen from the steppes of Khorassan, the black archers of Ethiopia, swordsmen from the banks of the Indus, the Oxus, the Euphrates, and the Nile, made ready against the enemies of the Great King. But no national cause inspired them, except the division of native Persians; and in the large host there was no uniformity of language, creed, race, or military system. Still, among them there were many gallant men, under a veteran general; they were familiarized with victory; and in contemptuous confidence their infantry, which alone had time to form, awaited the Athenian charge. On came the Greeks, with one unwavering line of levelled spears, against which the light targets, the short lances and scymetars of the Orientals offered weak defence. The front rank of the Asiatics must have gone down to a man at the first shock. Still they recoiled not, but strove by individual gallantry, and by the weight of numbers, to make up for the disadvantages of weapons and tactics, and to bear back the shallow line of the Europeans. In the centre, where the native Persians and the Sacae fought, they succeeded in breaking through the weaker part of the Athenian phalanx; and the tribes led by Aristides and Themistocles were, after a brave resistance, driven back over the plain, and chased by the Persians up the valley towards the inner country. There the nature of the ground gave the opportunity of rallying and renewing the struggle: and meanwhile, the Greek wings, where Miltiades had concentrated his chief strength, had routed the Asiatics opposed to them; and the Athenian and Plataean officers, instead of pursuing the fugitives, kept their troops well in hand, and wheeling round they formed the two wings together. Miltiades instantly led them against the Persian centre, which had hitherto been triumphant, but which now fell back, and prepared to encounter these new and unexpected assailants. Aristides and Themistocles renewed the fight with their re-organized troops, and the full force of the Greeks was brought into close action with the Persian and Sacian divisions of the enemy. Datis's veterans strove hard to keep their ground, and evening [ARISTOPH. Vesvoe 1085.] was approaching before the stern encounter was decided.
