 A historical school might be defined as a group of interrelated historians who share a significant number of specific assumptions about evidence, explanation, and narrative. The Annales school, established by Marc Bloch and Lucien Febvre in the 1920s, represented a distinctive and fertile approach to social history (Burguière 2009), united by shared assumptions about both topics and intellectual approaches to the past. Historiography becomes itself historical when we recognize that frameworks of assumptions about historical knowledge and reasoning change over time. On this assumption, the history of historical thinking and writing is itself an important subject. How did historians of various periods in human history conduct their study and presentation of history? Under this rubric we find books on the historiography of the ancient Greeks; Renaissance historiography; or the historiography of German romanticism. Arnaldo Momigliano’s writings on the ancient historians fall in this category (Momigliano 1990). In a nutshell, Momigliano is looking at the several traditions of ancient history-writing as a set of normative practices that can be dissected and understood in their specificity and their cultural contexts.
