Keresztes, P.: Imperial Rome and the Christians. Vol. 1. From Herod the Great to about 200 A.D. Lanham, MD./New York/London, 1989.
Keresztes focuses on Roman government and law. Chapter 2: “Paul, the Acts and Imperial Rome” (pp. 45-66), chapter 3: “The Profession of Christianity Made Criminal” (pp. 67-82) and chapter 4: “The Terror of Domitian” (pp. 83-101) are relevant to the themes of imperial cult and persecuties. Keresztes has quite another view than, e.g., Thompson, Book of Revelation (monograph).
