the Romans were endeavouring to disturb the peace of the people; they even required that the exiles should be reinstated. There was among the Achæans a traitor, Callicrates, who had entirely sold himself to the Romans, and who was so detested and execrated, that people were loth to go near him, or even to touch his garment: the more he became an object of contempt, the deeper he sank in his infamy. After the victory over Perseus, ten Roman commissioners appeared in Greece, two of whom, C. Claudius and Cn. Domitius, went to the Achæans. They asserted that among the papers of Perseus clear proofs had been discovered of the treachery of many eminent Achæans, and they now demanded that the Achæans should pronounce sentence of death upon all whom the Romans had found guilty. This the senate at once refused to do, declaring most properly, that the names must be given, the evidence produced, and the parties regularly tried; those who were brought in guilty should then be punished without mercy. But the envoys would have nothing to say to this, they wanted to give in the list after the executions only; and when they were urged to mention names, they said, that all those who had been _strategi_ were guilty. Then Xeno, who had formerly been _strategus_, got up, and declared that he was so conscious of his innocence, that he would take his trial before a tribunal in Achaia, and, if this were not sufficient, he would even defend himself at Rome. The Roman commissioners eagerly caught at this, and they had a list drawn up by Callicrates of those who were to be sent to Italy and judged there. There were more than a thousand of these; some of them made their escape, for which they were denounced as convicted offenders, and the punishment of death was inflicted upon them when they were taken. The rest were not brought before a court of justice at all, but were distributed as hostages in the municipal towns: it was only after the lapse of seventeen years, that the three hundred who were still alive, were let go. On this occasion, Polybius also came to Rome: his lot was soon bettered; for he got intimate with several families of high rank, and Æmilius Paullus himself made him the companion of his sons, that he might guide them into Greek learning.
