Original material for a biography of Peter the Hermit either does not exist in this country, or, if here, does not yield itself readily to knowledge and use. The "Life of Peter the Hermit," by D'Outremant, and another by AndrÉ Thevet, on which Michaud draws heavily, seem beyond reach, as are also the histories of the Crusades, by von Raumer and Maunbourg.

On examining a number of English and American "Histories of the Crusades," I found them to be largely abridgments or paraphrases of Michaud's monumental work.

It is, then, from Michaud and Milman chiefly that the writer has drawn the facts herein recorded, having often found it necessary to chasten the too pronounced Roman sympathies of Michaud by the equally pronounced Protestantism of Milman. To these authors I am so much indebted as to call for the fullest acknowledgment. The Rev. Dr. J. A. Faulkner, Professor in Drew Theological Seminary, has put me under great obligations by permitting me to use Hagenmeyer's "Life of Peter," especially valuable to the early and late parts of Peter's life.
