The Romans were careful not to assail the phalanx with their legions, but sent against it the archers and slingers, not one of whose missiles failed to take effect on the densely-crowded mass. The phalanx nevertheless retired slowly and in good order, till the elephants stationed in the interstices became frightened and broke the ranks. Then the whole army dispersed in tumultuous flight; an attempt to hold the camp failed, and only increased the number of the dead and the prisoners. The estimate of the loss of Antiochus at 50,000 men is, considering the infinite confusion, not incredible; the legions of the Romans had never been engaged, and the victory, which gave them a third continent, cost them 24 horsemen and 300 foot soldiers. Asia Minor submitted; including even Ephesus, whence the admiral had hastily to withdraw his fleet, and Sardes the residence of the court. Conclusion of Peace Expedition against the Celts of Asia Minor Regulation of the Affairs of Asia Minor The king sued for peace and consented to the terms proposed by the Romans, which, as usual, were just the same as those offered before the battle and consequently included the cession of Asia Minor. 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. But with the day of Magnesia Asia was erased from the list of great states; and never perhaps did a great power fall so rapidly, so thoroughly, and so ignominiously as the kingdom of the Seleucidae under this Antiochus the Great. He himself was soon afterwards (567) slain by the indignant inhabitants of Elymais at the head of the Persian gulf, on occasion of pillaging the temple of Bel, with the treasures of which he had sought to replenish his empty coffers.
