Now, determining no longer to conceal his intended
war with the Romans, he formed alliances by marriage with the neighboring kings. To Ptolemy in Egypt he sent his daughter Cleopatra, surnamed Syra, giving with her Cœle-Syria as a dowry, which he had taken away from Ptolemy himself, thus flattering the young king in order to keep him quiet during the war with the Romans. To Ariarathes, king of Cappadocia, he sent his daughter Antiochis, and the remaining one to Eumenes, king of Pergamus. But the latter, seeing that Antiochus was about to engage in war with the Romans and that he wanted to form a marriage connection with him on this account, refused her. To his brothers, Attalus and Philetærus, who were surprised that he should decline marriage relationship with so great a king, who was also his neighbor and who made the first overtures, he showed that the coming war would be of doubtful issue at first, but that the Romans would prevail in the end by their courage and perseverance. "If the Romans conquer," said he, "I shall be firmly seated in my kingdom. If Antiochus is the victor, I may expect to be stripped of all my possessions by my powerful neighbor, or, if I am allowed to reign, to be ruled over by him." For these reasons he rejected the proffered marriage.
