Book excerpt: [Preparations for the Gospels] The prominent position occupied by Eusebius of Caesarea in the Arian controversy and the Council of Nicaea has given rise to so many important treatises on his life and character, that it would be quite superfluous to prefix a formal biography to the present edition of one among his many literary works. It will be sufficient to mention a few of the best sources of information accessible to the English reader.
