Perseus was at the head of a numerous and well-appointed army, but of all his allies, only Cotys, king of the Odrysians, ventured to support him against so formidable a foe. Yet the war was protracted three years without any decisive result; nay, the balance of success seemed on the whole to incline in favor of Perseus, and many states, which before were wavering, now showed a disposition to join his cause. But his ill-timed parsimony restrained him from taking advantage of their offers, and in B.C. 168 the arrival of the Consul L. AEmilius Paullus completely changed the aspect of affairs. Perseus was driven from a strong position which he had taken up on the banks of the Enipeus, forced to retreat to Pydna, and, finally, to accept an engagement near that town. At first the serried ranks of the phalanx seemed to promise superiority; but its order having been broken by the inequalities of the ground, the Roman legionaries penetrated the disordered mass, and committed fearful carnage, to the extent, it is said, of 20,000 men. Perseus fled first to Pella, then to Amphipolis, and finally to the sanctuary of the sacred island of Samothrace, but was at length obliged to surrender himself to a Roman squadron. He was treated with courtesy, but was reserved to adorn the triumph of his conqueror. Such was the end of the Macedonian empire. The Senate decreed that Macedonia should be divided into four districts, each under the jurisdiction of an oligarchical council. Before leaving Greece, Paullus was commanded by the Senate to inflict a terrible punishment upon the Epirotes, because they had favored Perseus. Having placed garrisons in the seventy towns of Epirus, he razed them all to the ground in one day, and carried away 150,000 inhabitants as slaves. Epirus never recovered from this blow. In the time of Augustus the country was still a scene of desolation, and the inhabitants had only ruins and villages to dwell in. Paullus arrived in Italy toward the close of B.C. 167. The booty which he brought with him from Macedonia, and which he paid into the Roman treasury, was of enormous value; and his triumph, which lasted three days, was the most splendid that Rome had yet seen. Before his triumphal car walked the captive monarch of Macedonia, and behind it, on horseback, were his two eldest sons, Q. Fabius Maximus, and P. Scipio Africanus the younger, both of whom had been adopted into other families. But his glory was darkened by the death of his two younger sons, one dying a few days before, and the other a few days after his triumph. After the triumph Perseus was thrown into a dungeon, but, in consequence of the intercession of Paullus, he was released, and permitted to end his days in an honorable captivity at Pella. His son Alexander learned the Latin language, and became a public clerk at Rome.
