[273] There was also Simon, who had been a slave of Herod the king, but in other respects a comely person, of a tall and robust body; he was one that was much superior to others of his order, and had had great things committed to his care. This man was elevated at the disorderly state of things, and was so bold as to put a diadem on his head, while a certain number of the people stood by him, and by them he was declared to be a king, and thought himself more worthy of that dignity than any one else. He burnt down the royal palace at Jericho, and plundered what was left in it. He also set fire to many other of the king's houses in several places of the country, and utterly destroyed them, and permitted those that were with him to take what was left in them for a prey; and he would have done greater things, unless care had been taken to repress him immediately; for Gratus, when he had joined himself to some Roman soldiers, took the forces he had with him, and met Simon, and after a great and a long fight, no small part of those that came from Perea, who were a disordered body of men, and fought rather in a bold than in a skillful manner, were destroyed; and although Simon had saved himself by flying away through a certain valley, yet Gratus overtook him, and cut off his head. The royal palace also at Amathus, by the river Jordan, was burnt down by a party of men that were got together, as were those belonging to Simon. And thus did a great and wild fury spread itself over the nation, because they had no king to keep the multitude in good order, and because those foreigners who came to reduce the seditious to sobriety did, on the contrary, set them more in a flame, because of the injuries they offered them, and the avaricious management of their affairs.
