In the first book and the greater part of the second, where he is taken up with the preliminary introduction, he had ample sources before him, and his functions were only to abstract and compile; but when he comes to the final struggle with Rome, he would have us believe that he depended mainly on his independent knowledge. Recent investigation has thrown grave doubts on his claim, and has suggested that with Josephus it is true that "once a compiler, always a compiler." The habit of direct copying from the works of predecessors was fixed in the literary ethics of the day. In company with most of the historians of antiquity he introduces his general ideas upon the march of events in the form of addresses, which he puts into the mouth of the chief characters at critical moments. Here he is free to invent and intrude his own opinions, and here he almost unfailingly adopts a Roman attitude. The work, in fact, bears the character of official history, and has all the partiality of that form of literature. Titus, as the author proudly recalls, subscribed his own hand to it, and ordered that it should be published, and King Agrippa wrote a glowing testimonial to it in the most approved style.[1] It was accepted in Rome as the standard work upon the Jewish struggle. Patronage may have saved literature at certain epochs, but it always undermines the feeling of truth. It is not improbable that a juster appreciation of events was contained in the original writings of Josephus, but was corrected at the order of the royal traitor or the Imperial master, to whom he perforce submitted them.
