Book excerpt: All ten books of Eusebius' famous church history are presented here complete in a superb and authoritative translation. Eusebius' Ecclesiastical History is one of the first comprehensive, chronologically arranged histories ever written about the Christian church, and it is consulted by scholars and historians to this day. Eusebius authored his history as the Roman Empire's influence upon the European continent waned amid insurgencies and surrender of Roman lands to other peoples. This also a time in which Christianity's influence upon Europe's peoples burgeoned and grew. As one of a very few learned and scholarly Christians of his era Eusebius enjoyed a rare privilege: access to the document archives of the early Christian church. Much of these archives have since been lost; Eusebius' use of these long lost texts is the only window which readers of today have to such records. Thus, a sense of mystery is present as events for which scant evidence still exists are told.
