Josephus was the great apologist of his race. His chief aims in writing his histories were: (1) to excuse his own acts in connection with the great rebellion; (2) to show why the overwhelming calamity had overtaken his race; and (3) to answer the attack of their Gentile foes by tracing the remarkable history of his people, and by presenting in attractive form their beliefs, institutions, and laws. Of his two great historical works the one entitled _The Jewish War_ was issued probably between 75 and 79 A.D. It opens with the beginnings of the Maccabean struggle, and traces the history, with increasing detail, to the destruction of Jerusalem and the suppression of the Jewish revolt at Gyrene, two or three years before the book was written. His second great work was issued in 93 A.D. under the title of _The Antiquities of the Jews_. In twenty books it traces Israel's history from the earliest beginnings to the opening years of the Jewish war (68 A.D.). The first half of this extensive history is based on the author's free paraphrase of the Greek version of the Old Testament. For the latter half he draws largely from the apocryphal book of I Maccabees and from the writings of contemporary Greek and Jewish historians. Chief among these are Polybius, Nicolaus of Damascus, and Strabo. At certain points, where earlier sources fail him, he employs popular romances and late traditions. The result is that the different parts of his history are of widely varying values. All must be carefully tested by the canons of historical criticism. After due allowance has been made for his apologetic purpose and his well-known tendencies, a large and valuable body of historical facts remain with which it is possible at many otherwise obscure points to reconstruct the course of Israel's history.
