Eusebius was baptized and ordained in the city of Cesarea in Palestine. He became bishop there in about AD 313. Best known for his Ecclesiastical History, he had earlier produced an outline of world history (the Chronicle) presented country by country and year by year, from the earliest times to his own day. (Jerome’s Latin translation of Eusebius’s lost Greek original preserves and extends the second, tabular part.) Both of Eusebius’s works draw on earlier sources, preserving fragments of older histories otherwise lost. A favorite of Constantine, Eusebius also produced a panegyric life of the emperor.
