Peter Lampe builds a case from all the available evidence (archaeological, topographical, extant literature) in order to describe the Christian church in the city of Rome across the first two centuries or from Paul to Valentinus. Lampe is a first rate detective and I was enthralled from beginning to end. A reader will learn a great deal about the early church in the city of Rome and just as much about sound historical method and sober and strict assessment of the evidence.
