This volume investigates the evolution of religious authority in Rome by documenting the individuals who held ritual and administrative offices across eight centuries. Jörg Rüpke, a scholar of ancient religion, utilizes a prosopographical approach to map the intersection of pagan, Jewish, and Christian cults within the Roman state. By synthesizing documentary evidence into a comprehensive database of office-holders, the work provides a structural framework for understanding how religious identity and institutional power shifted from the Republic through the late Empire.

Scholars recognize this work as a foundational reference tool for the study of Roman religious history. Readers frequently note the academic density of the data, which serves as a primary resource for researchers examining social and institutional religious structures in antiquity.
