Eumenes and Antiochus had hitherto contended, independent. What was of more importance, the Galatians--who had been substantially in the power of Eumenes, ever since he had expelled the king of Pontus by force of arms from Caiatia and had on making peace extorted from him the promise that he would maintain no further communication with the Galatian princes--now, reckoning beyond doubt on the variance that had taken place between Eumenes and the Romans, if not directly instigated by the latter, rose against Eumenes, overran his kingdom, and brought him into great danger. Eumenes besought the mediation of the Romans; the Roman envoy declared his readiness to mediate, but thought it better that Attalus, who commanded the Pergamene army, should not accompany him lest the barbarians might be put into ill humour. Singularly enough, he accomplished nothing; in fact, he told on his return that his mediation had only exasperated the barbarians. No long time elapsed before the independence of the Galatians was expressly recognized and guaranteed by the senate. Eumenes determined to proceed to Rome in person, and to plead his cause in the senate. But the latter, as if troubled by an evil conscience, suddenly decreed that in future kings should not be allowed to come to Rome; and despatched a quaestor to meet him at Brundisium, to lay before him this decree of the senate, to ask him what he wanted, and to hint to him that they would be glad to see his speedy departure. The king was long silent; at length he said that he desired nothing farther, and re-embarked. He saw how matters stood: the epoch of half-powerful and half-free alliance was at an end; that of impotent subjection began. Humiliation of Rhodes
