Preparations of Antiochus for War with Rome
Antiochus employed the unexpected respite in strengthening his position at home and his relations with his neighbours before beginning the war, on which for his part he was resolved, and became all the more so, the more the enemy appeared to procrastinate. He now (561) gave his daughter Cleopatra, previously betrothed, in marriage to the young king of Egypt. That he at the same time promised to restore the provinces wrested from his son-in-law, was afterwards affirmed on the part of Egypt, but probably without warrant; at any rate the land remained actually attached to the Syrian kingdom.(3)
3. For this we have the testimony of Polybius (xxviii. i), which the sequel of the history of Judaea completely confirms; Eusebius (p. 117, -Mai-) is mistaken in making Philometor ruler of Syria. We certainly find that about 567 farmers of the Syrian taxes made their payments at Alexandria (Joseph, xii. 4, 7); but this doubtless took place without detriment to the rights of sovereignty, simply because the dowry of Cleopatra constituted a charge on those revenues; and from this very circumstance presumably arose the subsequent dispute.
