Aristides, the son of Lysimachus, was of the tribe Antiochis, and township of Alopece. As to his wealth, statements differ; some say he passed his life in extreme poverty, and left behind him two daughters whose indigence long kept them unmarried: but Demetrius, the Phalerian, in opposition to this general report, professes in his Socrates, to know a farm at Phalerum going by Aristides's name, where he was interred; and, as marks of his opulence, adduces first, the office of archon eponymus, which he obtained by the lot of the bean; which was confined to the highest assessed families, called the Pentacosiomedimni; second, the ostracism, which was not usually inflicted on the poorer citizens, but on those of great houses, whose elation exposed them to envy; third and last, that he left certain tripods in the temple of Bacchus, offerings for his victory in conducting the representation of dramatic performances, which were even in our age still to be seen, retaining this inscription upon them, "The tribe Antiochis obtained the victory: Aristides defrayed the charges: Archestratus's play was acted." But this argument, though in appearance the strongest, is of the least moment of any. For Epaminondas, who all the world knows was educated, and lived his whole life, in much poverty, and also Plato, the philosopher, exhibited magnificent shows, the one an entertainment of flute-players the other of dithyrambic singers; Dion, the Syracusan, supplying the expenses of the latter, and Pelopidas those of Epaminondas. For good men do not allow themselves in any inveterate and irreconcilable hostility to receiving presents from their friends, but while looking upon those that are accepted to be hoarded up and with avaricious intentions, as sordid and mean, they do not refuse such as, apart from all profit, gratify the pure love of honor and magnificence. Panaetius, again, shows that Demetrius was deceived concerning the tripod by an identity of name. For, from the Persian war to the end of the Peloponnesian, there are upon record only two of the name of Aristides, who defrayed the expense of representing plays and gained the prize neither of which was the same with the son of Lysimachus; but the father of the one was Xenophilus, and the other lived at a much later time, as the way of writing, which is that in use since the time of Euclides, and the addition of the name of Archestratus prove, a name which, in the time of the Persian war, no writer mentions, but which several, during the Peloponnesian war, record as that of a dramatic poet. The argument of Panaetius requires to be more closely considered. But as for the ostracism, everyone was liable to it, whom his reputation, birth, or eloquence raised above the common level; insomuch that even Damon, preceptor to Pericles, was thus banished, because he seemed a man of more than ordinary sense. And, moreover, Idomeneus says, that Aristides was not made archon by the lot of the bean, but the free election of the people. And if he held the office after the battle of Plataea, as Demetrius himself has written, it is very probable that his great reputation and success in the war, made him be preferred for his virtue to an office which others received in consideration of their wealth. But Demetrius manifestly is eager not only to exempt Aristides but Socrates likewise, from poverty, as from a great evil; telling us that the latter had not only a house of his own, but also seventy minae put out at interest with Crito.

Aristides being the friend and supporter of that Clisthenes, who settled the government after the expulsion of the tyrants, and emulating and admiring Lycurgus the Lacedaemonian above all politicians, adhered to the aristocratical principles of government; and had Themistocles, son to Neocles, his adversary on the side of the populace. Some say that, being boys and bred up together from their infancy, they were always at variance with each other in all their words and actions as well serious as playful, and that in this their early contention they soon made proof of their natural inclinations; the one being ready, adventurous, and subtle, engaging readily and eagerly in everything; the other of a staid and settled temper, intent on the exercise of justice, not admitting any degree of falsity, indecorum, or trickery, no, not so much as at his play. Ariston of Chios says the first origin of the enmity which rose to so great a height, was a love affair; they were rivals for the affection of the beautiful Stesilaus of Ceos, and were passionate beyond all moderation, and did not lay aside their animosity when the beauty that had excited it passed away; but, as if it had only exercised them in it, immediately carried their heats and differences into public business.

Themistocles, therefore, joining an association of partisans, fortified himself with considerable strength; insomuch that when some one told him that were he impartial, he would make a good magistrate; "I wish," replied he, "I may never sit on that tribunal where my friends shall not plead a greater privilege than strangers." But Aristides walked, so to say, alone on his own path in politics, being unwilling, in the first place, to go along with his associates in ill doing, or to cause them vexation by not gratifying their wishes; and, secondly, observing that many were encouraged by the support they had in their friends to act injuriously, he was cautious; being of opinion that the integrity of his words and actions was the only right security for a good citizen.

However, Themistocles making many dangerous alterations, and withstanding and interrupting him in the whole series of his actions, Aristides also was necessitated to set himself against all Themistocles did, partly in self-defense, and partly to impede his power from still increasing by the favor of the multitude; esteeming it better to let slip some public conveniences, rather than that he by prevailing should become powerful in all things. In fine, when he once had opposed Themistocles in some measures that were expedient, and had got the better of him, he could not refrain from saying, when he left the assembly, that unless they sent Themistocles and himself to the barathrum, there could be no safety for Athens. Another time, when urging some proposal upon the people, though there were much opposition and stirring against it, he yet was gaining the day; but just as the president of the assembly was about to put it to the vote, perceiving by what had been said in debate the inexpediency of his advice, he let it fall. Also he often brought in his bills by other persons, lest Themistocles, through party spirit against him, should be any hindrance to the good of the public.

In all the vicissitudes of public affairs, the constancy he showed was admirable, not being elated with honors, and demeaning himself tranquilly and sedately in adversity; holding the opinion that he ought to offer himself to the service of his country without mercenary news and irrespectively of any reward, not only of riches, but even of glory itself. Hence it came, probably, that at the recital of these verses of Aeschylus in the theater, relating to Amphiaraus,

For not at seeming just, but being so
He aims; and from his depth of soil below,
Harvests of wise and prudent counsels grow,

the eyes of all the spectators turned on Aristides, as if this virtue, in an especial manner, belonged to him.
