[238] Now when Antiochus was come to Tarsus in Cilicia, Petus ordered a centurion to go to him, and send him in bonds to Rome. However, Vespasian could not endure to have a king brought to him in that manner, but thought it fit rather to have a regard to the ancient friendship that had been between them, than to preserve an inexorable anger upon pretense of this war. Accordingly, he gave orders that they should take off his bonds, while he was still upon the road, and that he should not come to Rome, but should now go and live at Lacedemon; he also gave him large revenues, that he might not only live in plenty, but like a king also. When Epiphanes, who before was in great fear for his father, was informed of this, their minds were freed from that great and almost incurable concern they had been under. He also hoped that Caesar would be reconciled to them, upon the intercession of Vologeses; for although he lived in plenty, he knew not how to bear living out of the Roman empire. So Caesar gave him leave, after an obliging manner, and he came to Rome; and as his father came quickly to him from Lacedemon, he had all sorts of respect paid him there, and there he remained.
