City of demons

the long version

"City of Demons presents three richly detailed case studies of urban church leaders who are demonologists and active and innovative exorcists in the midst of dangerous, potentially violent religious conflicts dominating their cities. John Chrysostom of Antioch, Cyril of Jerusalem, and Ambrose of Milan have individually been described as exemplary church figures, who Christianize their fourth-century cities in ways that contribute to progress rather than to decline ... In contrast ... this book attends closely to these three leaders' demonological discourses and related ritual descriptions ... City of Demons argues that each leader's actions result in the material transformation (i.e, Christianization) of his respective urban environment."--Introduction, p. 3.
