This volume offers a counterbalance to the dismissal that Orosius'sHistories Against the Paganshas suffered in most recent criticism. Orosius is traditionally considered to be a mediocre scholar and an essentially worthless historian. This book takes his literary endeavour seriously, recognizing the unique contribution theHistoriesmade at a crucial moment of debate and uncertainty, where the present was shaped by restructuring the past. The significance of theHistoriesis recognised intrinsically rather than only in comparison with other texts and authors, principally Augustine of Hippo, Orosius's mentor. The approach of the book is historiographical, exploring the form, purpose, and meaning of theHistories. The themes of divine providence, monotheism, and imperial authority are examined, and the subjects of war and the sack of Rome receive extended analysis. The book foregrounds Orosius's significant historiographical innovations that are seldom explored, such as the subversion of imperial history within a Christian spectrum in the synchronization of the emperor Augustus and Christ. Each chapter contributes to the progression of knowledge about Orosius'sHistoriesand the wider literary and historiographical culture of disruption that characterised the late fourth and early fifth centuries CE.
