As soon as he thought that it was Babylon 's fate to fall, he came and inquired of Darius if taking Babylon were very important to him; and when he was assured that it was, he then cast about for a plan by which the city's fall would be accomplished by him alone; for good service among the Persians is very much esteemed, and rewarded by high preferment. He could think of no other way to bring the city down than to mutilate himself and then desert to the Babylonians; so, making light of it, he mutilated himself beyond repair, and after cutting off his nose and ears and cropping his hair as a disfigurement and scourging himself, he came before Darius.
