When Antiochus was overcome, the Romans pressed harder upon Greece, and encompassed the Achaeans with their power; the popular leaders in the several cities yielded before them; and their power speedily, under the divine guidance, advanced to the consummation due to it in the revolutions of fortune. Philopoemen, in this conjecture, carried himself like a good pilot in a high sea, sometimes shifting sail, and sometimes yielding, but still steering steady;and omitting no opportunity nor effort to keep all who were considerable, whether for eloquence or riches, fast to the defence of their common liberty.
Aristaenus, a Megalopolitan of great credit among the Achaeans, but always a favourer of the Romans, saying one day in the senate that the Romans should not be opposed, or displeased in any way, Philopoemen heard him with an impatient silence; but at last, not able to hold longer, said angrily to him, "And why be in such haste, wretched man, to behold the end of Greece?" Manius, the Roman consul, after the defeat of Antiochus, requested the Achaeans to restore the banished Lacedaemonians to their country, which motion was seconded and supported by all the interest of Titus. But Philopoemen crossed it, not from ill-will to the men, but that they might be beholden to him and the Achaeans, not to Titus and the Romans. For when he came to be general himself, he restored them. So impatient was his spirit of any subjection and so prone his nature to contest everything with men in power.
Being now three score and ten, and the eighth time general, he was in hope to pass in quiet, not only the year of his magistracy, but his remaining life. For as our diseases decline, as it is supposed with our declining bodily strength, so the quarrelling humour of the Greeks abated much with their failing political greatness. But fortune or some divine retributive power threw him down in the close of his life, like a successful runner who stumbles at the goal. It is reported, that being in company where one was praised for a great commander, he replied, there was no great account to be made of a man who had suffered himself to be taken alive by his enemies.
A few days after, news came that Dinocrates the Messenian, a particular enemy to Philopoemen, and for his wickedness and villainies generally hated, had induced Messene to revolt from the Achaeans, and was about to seize upon a little place called Colonis. Philopoemen lay then sick of a fever at Argos. Upon the news he hasted away, and reached Megalopolis, which was distant above four hundred furlongs, in a day. From thence he immediately led out the horse, the noblest of the city, young men in the vigour of their age, and eager to proffer their service, both from attachment to Philopoemen and zeal for the cause. As they marched towards Messene, they met with Dinocrates, near the hill of Evander, charged and routed him. But five hundred fresh men, who, being left for a guard to the country, came in late, happening to appear, the flying enemy rallied again about the hills.
Philopoemen, fearing to be enclosed, and solicitous for his men, retreated over ground extremely disadvantageous, bringing up the rear himself. As he often faced, and made charges upon the enemy, he drew them upon himself; though they merely made movements at a distance, and shouted about him, nobody daring to approach him. In his care to save every single man, he left his main body so often, that at last he found himself alone among the thickest of his enemies. Yet even then none durst come up to him, but being pelted at a distance, and driven to stony steep places, he had great difficulty, with much spurring, to guide his horse aright. His age was no hindrance to him, for with perpetual exercise it was both strong and active; but being weakened with sickness, and tired with his long journey, his horse stumbling, he fell encumbered with his arms, and faint, upon a hard and rugged piece of ground. His head received such a shock with the fall that he lay awhile speechless, so that the enemy, thinking him dead, began to turn and strip him. But when they saw him lift up his head and open his eyes, they threw themselves all together upon him, bound his hands behind him, and carried him off, every kind of insult and contumely being lavished on him who truly had never so much as dreamed of being led in triumph by Dinocrates.
The Messenians, wonderfully elated with the news, thronged in swarms to the city gates. But when they saw Philopoemen in a posture so unsuitable to the glory of his great actions and famous victories, most of them, struck with grief and cursing the deceitful vanity of human fortune, even shed tears of compassion at the spectacle. Such tears by little and little turned to kind words, and it was almost in everybody's mouth that they ought to remember what he had done for them, and how he had preserved the common liberty, by driving away Nabis. Some few, to make their court to Dinocrates, were for torturing and then putting him to death as a dangerous and irreconcilable enemy;all the more formidable to Dinocrates, who had taken him a prisoner, should he after this misfortune regain his liberty. They put him at last into a dungeon underground, which they called the treasury, a place into which there came no air nor light from abroad; and which, having no doors, was closed with a great stone. This they rolled into the entrance and fixed, and placing a guard about it, left him.
