The chief authorities consulted in the preparation of this book are named in the text. Besides the well-known works of reference on the English Cathedrals, and the "Monastic Chronicles," there are several that deal with Peterborough alone, of which the most important and valuable are "Gunton's History" with Dean Patrick's Supplement, "Craddock's History," the monographs by Professor Paley and Mr Poole, and the Guide of Canon Davys. If I have ventured to differ from some of these writers on various points, I must appeal, in justification, to a careful and painstaking study of the Cathedral and its history, during a residence at Peterborough of more than twenty years.

            My best thanks are due to Mr Caster of Peterborough, for permission to incorporate with this account the substance of a Guide, which I prepared for him, published in 1893; and to Mr Robert Davison of London, for his description of the Mosaic Pavement, executed by him for the Choir. I desire also to express my thanks for the drawings supplied by Mr W.H. Lord, Mr H.P. Clifford, and Mr O.R. Allbrow; and to acknowledge my indebtedness to the Photochrom Company, Ld., and to Messrs S.B. Bolas & Co., for their excellent photographs.
