Eusebius lived in the late third and early fourth centuries in Caesarea Palestine. His History of the Church chronicles the time from Christ to the victory of Constantine over Licinius. He wrote in Greek, but this translation Latinizes the names. Eusebius covers the period of Jewish persecution in the early first millennium a.d.; goes through the succession of the bishops of Rome, Antioch, Alexandria, Jerusalem, etc.; gives the account of heretical movements; and gives numerous examples of Christian martyrs in times of persecution. In the back of this edition is an extensive "Who's Who in Eusebius" spanning some 88 pages. It is a very useful tool in the reading of The History of the Church. It may also prove a valuable quick reference in further studies on early Christianity. Eusebius's style allows him to extensively quote several authors and historians in the early first millennium. His ten books of The History of the Church are riddled with passages from Josephus, Origen, Philo, Hegesippus, and the like. Also, behind the Who's Who in Eusebius, are a few appendices. I would highly recommend reading the appendices B, C, and D before undertaking the body of the book. A brief knowledge of the Roman empire at the time and Christianity will greatly benefit the reader.
