The Athenians at this time had recently expelled Hippias, the son of Pisistratus, the last of their tyrants. They were in the full glow of their newly-recovered liberty and equality; and the constitutional changes of Cleisthenes had inflamed their republican zeal to the utmost. Miltiades had enemies at Athens; and these, availing themselves of the state of popular feeling, brought him to trial for his life for having been tyrant of the Chersonese. The charge did not necessarily import any acts of cruelty or wrong to individuals: it was founded on so specific law; but it was based on the horror with which the Greeks of that age regarded every man who made himself compulsory master of his fellow-men, and exercised irresponsible dominion over them. The fact of Miltiades having so ruled in the Chersonese was undeniable; but the question which the Athenians, assembled in judgment, must have tried, was, whether Miltiades, by becoming tyrant of the Chersonese, deserved punishment as an Athenian citizen. The eminent service that he had done the state in conquering Lemnos and Imbros for it, pleaded strongly in his favour. The people refused to convict him. He stood high in public opinion; and when the coming invasion of the Persians was known, the people wisely elected him one of their generals for the year. Two other men of signal eminence in history, though their renown was achieved at a later period than that of Miltiades, were also among the ten Athenian generals at Marathon. One was Themistocles, the future founder of the Athenian navy and the destined victor of Salamis: the other was Aristides, who afterwards led the Athenian troops at Plataea, and whose integrity and just popularity acquired for his country, when the Persians had finally been repulsed, the advantageous pre-eminence of being acknowledged by half of the Greeks as their impartial leader and protector. It is not recorded what part either Themistocles or Aristides took in the debate of the council of war at Marathon. But from the character of Themistocles, his boldness, and his intuitive genius for extemporizing the best measures in every emergency (a quality which the greatest of historians ascribes to him beyond all his contemporaries), we may well believe that the vote of Themistocles was for prompt and decisive action. [See the character of Themistocles in the 138th section of the first book of Thucydides, especially the last sentence.] On the vote of Aristides it may be more difficult to speculate. His predilection for the Spartans may have made him wish to wait till they came up; but, though circumspect, he was neither timid as a soldier nor as a politician; and the bold advice of Miltiades may probably have found in Aristides a willing, most assuredly it found in him a candid, hearer.
