From the early modern period, Greek historiography has been studied in the context of Cicero's notion historia magistra vitae and considered to exclude conceptions of the future as different from the present and past. Comparisons with the Roman, Judeo-Christian and modern historiography have sought to justify this perspective by drawing on a category of the future as a temporal mode that breaks with the present. In this volume, distinguished classicists and historians challenge this contention by raising the question of what the future was and meant in antiquity by offering fresh considerations of prognostic and anticipatory voices in Greek historiography from Herodotus to Appian and by tracing the roots of established views on historical time in the opposition between antiquity and modernity. They look both at contemporary scholarly argument and the writings of Greek historians in order to explore the relation of time, especially the future, to an idea of the historical that is formulated in the plural and is always in motion. By reflecting on the prognostic of historical time the volume will be of interest not only to classical scholars, but to all who are interested in the history and theory of historical time.
