Josephus (AD 37-?100), a pro-Roman Jew closely associated with the emperor Titus, is one of the earliest systematic commentators on the Bible, as well as one of the foremost historians of the beginning of the Christian era. Politically, Josephus was pro-Roman, and although he had no sympathy for extreme Jewish nationalism, he was a zealous defender of Jewish religion and culture. This text examines the principles that guided Josephus in his understanding of the Bible, investigating his creative contribution in the writing of biblical accounts. The study evaluates Josephus as a historian and demonstrates the originality and consistency of his work as an author.
