Project Description: Religious Dissension and Social Order in Late Antique Rome

This project examines religious conflicts in Rome during the fourth and early fifth centuries, focusing on documents preserved in two significant late canonical collections: the Collectio Avellana and the Collectio Quesnelliana. These collections contain records of contentious papal elections and violent doctrinal disputes within Rome. By analysing these documents, which are exclusively conserved in these collections, historians and legal scholars can gain a profound understanding of the imperial administration and religious jurisdiction of the period. Specifically, the study sheds light on the functions of the urban prefecture, offering valuable insights into the drafting and communication of laws during Late Antiquity.
