In this work, Paul Michael Kurtz examines the historiography of ancient Israel in the German Empire through the prism of religion, as a structuring framework not only for writings on the past but also for the writers of that past themselves. The author investigates what biblical scholars, theologians, orientalists, philologists, and ancient historians considered religion and history to be, how they understood these conceptual categories, and why they studied them in the manner they did. Focusing on Julius Wellhausen and Hermann Gunkel, his inquiry scrutinizes to what extent, in an age of allegedly neutral historical science, the very enterprise of reconstructing the ancient past was shaped by liberal Protestant structures shared by dominant historians from the late nineteenth and early twentieth centuries.
