Till they were ratified, the army remained in Asia Minor at the expense of the king; which came to cost him not less than 3000 talents (730,000 pounds).

Antiochus himself in his careless fashion soon consoled himself for the loss of half his kingdom; it was in keeping with his character, that he declared himself grateful to the Romans for saving him the trouble of governing too large an empire.
