(M420) Aristides was inferior to both Alcibiades and Themistocles in genius, in resource, in boldness, and in energy; but superior in virtue, in public fidelity, and moral elevation. He pursued a consistent course, was no demagogue, unflinching in the discharge of trusts, just, upright, unspotted. Such a man, of course, in a corrupt society, would be exposed to many enmities and jealousies. But he was, on the whole, appreciated, and died, in a period of war and revolution, a poor man, with unbounded means of becoming rich—one of the few examples which our world affords of a man who believed in virtue, in God, and a judgment to come, and who preferred the future and spiritual to the present and material—a fool in the eyes of the sordid and bad—a wise man according to the eternal standards. (M421) Aristides, Miltiades, and perhaps Themistocles, were elected among the ten generals, by the ten tribes, in the year that Datis led his expedition to Marathon. Each of the ten generals had the supreme command of the army for a day. Great alarm was felt at Athens as tidings reached the city of the advancing and conquering Persians. Couriers were sent in hot haste to the other cities, especially Sparta, and one was found to make the journey to Sparta on foot—one hundred and fifty miles—in forty-eight hours. The Spartans agreed to march, without delay, after the last quarter of the moon, which custom and superstition dictated. This delay was fraught with danger, but was insisted upon by the Spartans. (M422) Meanwhile the dangers multiplied and thickened, that not a moment should be lost in bringing the Persians into action. Five of the generals counseled delay. The polemarch, Calimachus, who then had the casting vote, decided for immediate action. Themistocles and Aristides had seconded the advice of Miltiades, to whom the other generals surrendered their days of command—a rare example of patriotic disinterestedness. The Athenians marched at once to Marathon to meet their foes, and were joined by the Platæans, one thousand warriors, from a little city—the whole armed population, which had a great moral effect.
