The English version of the Ecclesiastical History" in the following pages is a revision of the translation of Dr. Giles, which is itself a revision of the earlier rendering of Stevens. In the present edition very considerable alterations have been made, but the work of Dr. Giles remains the basis of the translation. The Latin text used throughout is Mr. Plummer's. Since the edition of Dr. Giles appeared in 1842, so much fresh work on the subject has brought so many new facts to light, that it has been found necessary to rewrite the notes almost entirely, and to add a new introduction. After the appearance of Mr. Plummer's edition of the Historical Works of Bede, it might seem superfluous, for the present at least, to write any notes at all on the "Ecclesiastical History." The present volume, however, is intended to fulfil a different and much humbler function. There has been no attempt at any original work, and no new theories are advanced. The object of the book is merely to present in a short and convenient form the substance of the views held by trustworthy authorities, and it is hoped that it may be found useful by those students who have either no time or no inclination to deal with more important works."
