THE considerations which induced me to undertake this monograph are mentioned in the introductory chapter. How far the design there indicated has been satisfactorily fulfilled, it is for others to decide. I am of course conscious of defects, for every workman’s ideal aim should be higher than what he can actually accomplish. The work has incurred a certain risk from having been once or twice suspended for a considerable period; but I have always returned to it with increased interest and pleasure, nor can I charge myself with having wittingly bestowed less pains on one part than another. I have endeavoured to make it a trustworthy narrative by drawing from the most original sources to which I could gain access; and where, as in those portions which touch on secular history, the lead of general historians, such as Gibbon or De Broglie, has been followed, I have, as far as possible, consulted the authorities to which they refer. To modern authors from whom I have derived valuable assistance for special parts of the work, such as M. Amédée Thierry and Dr. Foerster, my obligations are acknowledged in their proper place.
