As the high-ranking Bishop of Alexandria from 328 to 373, Athanasius came into conflict with no fewer than four Roman emperors—Constantine himself, his son Constantius, Julian the Apostate, and the “Arian” Valens. In this new reconstruction of Athanasius’s career, Timothy D. Barnes analyzes the nature and extent of the Bishop’s power, especially as it intersected with the policies of these emperors.

Repeatedly condemned and deposed by church councils, the Bishop persistently resurfaced as a player to contend with in ecclesiastic and imperial politics. Barnes’s work reveals that Athanasius’s writings, though a significant source for this period, are riddled with deliberate misinterpretations, which historians through the ages have uncritically accepted.

Untangling longstanding misconceptions, Barnes reveals the Bishop’s true role in the struggles within Christianity, and in the relations between the Roman emperor and the Church at a critical juncture.

This study of the Roman Empire in the age of Constantine offers a thoroughly new assessment of the part Christianity played in the Roman world of the third and fourth centuries.

Timothy D. Barnes gives the fullest available narrative history of the reigns of Diocletian and Constantine. He analyzes Constantine’s rise to power and his government, demonstrating how Constantine’s sincere adherence to Christianity advanced his political aims. He explores the whole range of Eusebius’ writings, especially those composed before Constantine became emperor, and shows that many attitudes usually deemed typical of the “Constantinian revolution” were prevalent before the new Christian empire came into existence. This authoritative political and cultural history of the age of Constantine will prove essential to students and historians of the ancient world.
