After Luke's history, spanning roughly the first thirty years of church history, the work of Josephus, who chronicled Roman and Jewish history about the same time the New Testament was being written, is the first external historical documentation of Jesus' life and impact. Ignatius, the bishop of Antioch who was a child in the time of Jesus, and Eusebius, the bishop of Caesarea in Palestine in the time of Constantine the Great, were the next recorders of some aspects of church history.
