a fountain of inspiration to anyone who essays to write about Rome in the Middle Ages. Not only are its springs inexhaustible: the fountain itself is so clear and beautiful that to take draughts from it is a perpetual delight. The smaller volume of Gregorovius, from which I have made several quotations—the Tombs of the Popes, translated by Mr. R. W. Seton Watson, and published by Archibald Constable & Co. (with whose permission these quotations have been made) I should not have used so much but for the admirable English of the translation. Other books of Messrs. Bell, to which I have referred a few times, are Miss Mary Knight Potter's The Art of the Vatican, and Roscoe's Life of Leo X.
Mr. John Murray has published several books which I have constantly before me. Besides Murray's Handbook to Rome, which has always been recognized as one of the best in any language, there are Sir A. H. Layard's Handbook to the Italian Schools of Painting, based on Kugler's handbook, sixth edition (2 vols., 24s. nett); Dennis's Cities and Cemeteries of Etruria (2 vols., 36s. nett); Nielsen's History of the Papacy in the Nineteenth Century, 1907 (2 vols., 24s. nett); and Mr. W. G. Waters's Translation of the Journal of Montaigne's Travels, which contains some interesting passages about the Vatican Library.
