The book tells about the famous Jewish historian and political figure of the 1st century AD Josephus (Joseph ben Mattityahu), an eyewitness, active participant and chronicler of the Jewish War - a grand uprising of Jews against the rule of the Romans. We largely know about the main events of this war, the most tragic in the history of the Jewish people - the death of Jerusalem and the destruction of the Jerusalem Temple - from his writings. But who was their author: a traitor to his people (as most Jews considered him for almost two millennia), an assistant to the Roman Caesars, who received the right to bear their family name - Flavius, and composed his historical works to please them - or a person devoted to the faith fathers and tried to defend the interests of their people until the end of their lives? What is the significance of Josephus’s testimony about the personality of Jesus Christ for the apologetics of Christianity and why were his books translated into many languages (including Old Russian) in ancient times? These are the questions posed by the author of the book, the famous Israeli writer, historian and journalist Peter Lukimson.
