Book excerpt: The fourth and fifth centuries AD were an era of religious conflict, political change and military conflict. The responses of contemporary historians to these turbulent times reflect their diverse backgrounds - Christian and pagan, writing in both Greek and Latin, documenting church and state. This volume is the first to offer an accessible survey of the lives and works of these varied figures. The first half of the book explores the structure, style, purpose and nature of their writings. The second half compares and contrasts the information the historians provide, and the views they express on some central topics. These range from historiography, government and religion to barbarian invasions, and the controversial emperors Julian 'The Apostate' and Theodosius.
