=37.= He then overran Asia Minor, and crossing the Hellespont, seized the Thracian Chersonesus. The Romans, who had conquered Philip and were guardians of Ptolemy, now sent an embassy to Antiochus, requiring him to surrender all his conquests of territory belonging to either prince, B. C. 196. Antiochus indignantly rejected their interference, and prepared for war, with the aid of their great enemy, Hannibal, who had taken refuge at his court. In 192 B. C., he crossed into Greece and captured Chalcis; but he was signally defeated soon after by the Romans, at Thermopylæ, and compelled to withdraw from Europe. They followed him across the sea, and by two naval victories gained the western coast of Asia Minor. The two Scip´ios crossed the Hellespont and defeated Antiochus a fourth time, near Magnesia, in Lydia. He obtained peace only by surrendering all Asia Minor except Cilicia, with his navy and all his elephants, and by paying an enormous war indemnity. Twenty hostages were given for the payment, among whom was Antiochus Epiphanes, the king’s son. The king of Pergamus received the ceded provinces, and became a most formidable rival to Syria. To meet his engagements with the Romans, Antiochus plundered the temples of Asia, and in a commotion excited by this means in Elyma´is, he lost his life. =38.= Seleucus IV. (Philop´ator) had a reign of eleven years, unmarked by important events. The kingdom was exhausted, and the Romans were ready to seize any exposed province at the least hostile movement of the Syrians. Heliodo´rus, the treasurer, at length murdered his master and assumed the crown; but his usurpation was cut short by the arrival of Antiochus Epiphanes, brother of the late king, who with the aid of Eumenes, king of Pergamus, established himself upon the throne. =39.= Antiochus IV. had been thirteen years a hostage at Rome, and surprised his people by the Roman customs which he introduced. He made a four years’ war against Egypt, and had nearly conquered the country when the Romans interfered, and commanded him to give up all his conquests. He was forced to obey, but he vented his rage upon the Jews, whose temple he plundered and desecrated. They sprang to arms, under the leadership of Mat´tathi´as, the priest, and his brave son, Judas Maccabæ´us, and defeated the army sent to subdue them. Antiochus, who was now in the East, set forth in person to avenge this insult to his authority. On his way, he attempted to plunder the temple at Elymais, and was seized with a furious insanity, in which he died. Both Jews and Greeks believed his madness to be a judgment for his sacrilege.
