I have already stated that Cydas of Crete, while, serving in the army of Eumenes and held in especial honour by him, had in the first place had interviews with Cheimarus, one of the Cretans in the army of Perseus, and again had approached the walls of Demetrias, and conversed first with Menecrates, and then with Antimachus. Again, that Herophon had been twice on a mission from Perseus to Eumenes, and that the Romans on that account began to have reasonable suspicions of king Eumenes, is rendered clear from what happened to Attalus. For they allowed this prince to come to Rome from Brundisium, and to transact the business he had on hand, and finally gave him a favourable answer and dismissed him with every mark of kindness, although he had done them no service of any importance in the war with Perseus; while Eumenes, who had rendered them the most important services, and had assisted them again and again in their wars with Antiochus and Perseus, they not only prevented from coming to Rome, but bade him leave Italy within a certain number of days, though it was mid-winter. Therefore it is quite plain that some intriguing had been taking place between Perseus and Eumenes to account for the alienation of the Romans from the latter. What this was, and how far it went, is our present subject of inquiry.
