These actions obtained him distinguished marks of affection and honour in all the theatres of Greece, but not without the secret ill-will of Titus Flamininus, who was naturally eager for glory, and thought it but reasonable a consul of Rome should be otherwise esteemed by the Achaeans than a common Arcadian; especially as there was no comparison between what he and what Philopoemen had done for them, he having by one proclamation restored all Greece, as much as had been subject to Philip and the Macedonians, to liberty. After this, Titus made peace with Nabis, and Nabis was circumvented and slain by the Aetolians. Things being then in confusion at Sparta, Philopoemen laid hold of the occasion, and coming upon them with an army, prevailed with some by persuasion, with others by fear, till he brought the whole city over to the Achaeans. As it was no small matter for Sparta to become a member of Achaea, this action gained him infinite praise from the Achaeans, for having strengthened their confederacy by the addition of so great and powerful a city, and not a little good-will from the nobility of Sparta itself, who hoped they had now procured an ally who would defend their *******.
Accordingly, having raised a sum of one hundred and twenty silver talents by the sale of the house and goods of Nabis, they decreed him the money, and sent a deputation in the name of the city to present it. But here the honesty of Philopoemen showed itself clearly to be a real, uncounterfeited virtue. For, first of all, there was not a man among them who would undertake to make him this offer of a present, but every one excusing himself, and shifting it off upon his fellow, they laid the office at last on Timolaus, with whom he had lodged at Sparta. Then Timolaus came to Megalopolis, and was entertained by Philopoemen; but struck into admiration with the dignity of his life and manners, and the simplicity of his habits, judging him to be utterly inaccessible to any such considerations, he said nothing, but pretending other business, returned without a word mentioned of the present. He was sent again, and did just as formerly. But the third time with much ado, and faltering in his words, he acquainted Philopoemen with the good-will of the city of Sparta to him. Philopoemen listened obligingly and gladly; and then went himself to Sparta, where he advised them, not to bribe good men and their friends, of whose virtue they might be sure without charge to themselves; but to buy off and silence ill citizens, who disquieted the city with their seditious speeches in the public assemblies; for it was better to bar liberty of speech in enemies than friends. Thus it appeared how much Philopoemen was above bribery.
Diophanes being afterwards general of the Achaeans, and hearing the Lacedaemonians were bent on new commotions, resolved to chastise them; they, on the other side, being set upon war, were embroiling all Peloponnesus. Philopoemen on this occasion did all he could to keep Diophanes quiet and to make him sensible that as the times went, while Antiochus and the Romans were disputing their pretensions with vast armies in the heart of Greece, it concerned a man in his position to keep a watchful eye over them, and dissembling, and putting up with any less important grievances, to preserve all quiet at home.
Diophanes would not be ruled, but joined with Titus, and both together falling into Daconia, marched directly to Sparta. Philopoemen, upon this, took, in his indignation, a step which certainly was not lawful, nor in the strictest sense just, but boldly and loftily conceived.
Entering into the town himself, he, a private man as he was, refused admission to both the consul of Rome and the general of the Achaeans, quieted the disorders in the city, and reunited it on the same terms as before to the Achaean confederacy.
Yet afterwards, when he was general himself, upon some new misdemeanour of the Lacedaemonians, he brought back those who had been banished, put, as Polybius writes, eighty, according to Aristocrates three hundred and fifty, Spartans to death, razed the walls, took away a good part of their territory and transferred it to the Megalopolitans, forced out of the country and carried into Achaea all who had been made citizens of Sparta by tyrants, except three thousand who would not submit to banishment. These he sold for slaves, and with the money, as if to exult over them, built a colonnade at Megalopolis. Lastly, unworthily trampling upon the Lacedaemonians in their calamities, and gratifying his hostility by a most oppressive and arbitrary action, he abolished the laws of Lycurgus, and forced them to educate their children and live after the manner of the Achaeans; as though, while they kept to the discipline of Lycurgus, there was no humbling their haughty spirits. In their present distress and adversity they allowed Philopoemen thus to cut the sinews of their commonwealth asunder, and behave themselves humbly and submissively.
But afterwards, in no long time, obtaining the support of the Romans, they abandoned their new Achaean citizenship; and as much as in so miserable and ruined a condition they could, re-established their ancient discipline.
When the war betwixt Antiochus and the Romans broke out in Greece, Philopoemen was a private man. He repined grievously when he saw Antiochus lay idle at Chalcis, spending his time in unreasonable courtship and weddings, while his men lay dispersed in several towns, without order, or commanders, and minding nothing but their pleasures. He complained much that he was not himself in office, and said he envied the Romans their victory; and that if he had had the fortune to be then in command, he would have surprised and killed the whole army in the taverns.
