Flavius Josephus, born Yosef ben Matityahu in Jerusalem, was a first-century Romano-Jewish scholar, historian, and hagiographer. Born in the year 37 CE into a priestly Jewish family, Josephus was well-educated, excelling in the study of Jewish law and history. His most significant works include 'Jewish Antiquities,' 'The Jewish War,' and 'Against Apion,' where he defends Judaism and its ancient heritage against detractors. In 'Against Apion,' Josephus refutes the anti-Jewish allegations made by Apion and others, providing a valuable apologetic source concerning the Jewish people and their ancient traditions. He wrote in a meticulous and detailed style, offering insights into first-century Judaism and the background of early Christianity. Josephus' works are pivotal primary sources for the understanding of the Judeo-Roman world, giving scholars comprehensive narratives of Jewish history from the creation up to the First Jewish–Roman War, including the fall of Jerusalem in 70 CE. His adoption of the Roman perspective and self-serving accounts has stirred debate, but his literary contributions remain indispensable for historical studies of this era (Feldman, 1998).
