The titles of more than five hundred books and pamphlets relating to Pompeii are given in Furchheim's _Bibliografia di Pompei_ (second edition, Naples, 1891). To this list should be added an elaborate work on the temple of Isis, _Aedis Isidis Pompeiana_, which is soon to appear. The copperplates for the engravings were prepared at the expense of the old Accademia ercolanese, but only the first section of the work was published; the plates, fortunately, have been preserved without injury, and the publication has at last been undertaken by Professor Sogliano. Professor Mau wishes to make grateful acknowledgment of obligation to Messrs. C. Bazzani, R. Koldewey, G. Randanini, and G. Tognetti for kind assistance in making ready for the engraver the drawings presenting restorations of buildings; to the authorities of the German Archaeological Institute for freely granting the use of a number of drawings in its collection; and to the photographer, Giacomo Brogi of Florence, for placing his collection of photographs at the author's disposal and making special prints for the use of the engraver. In addition to the photographs obtained from Brogi, a small number were furnished for the volume by the translator, and a few were derived from other sources. The restorations are not fanciful. They were made with the help of careful measurements and of computations based upon the existing remains; occasionally also evidence derived from reliefs and wall paintings was utilized. Uncertain details are generally omitted. It is due to Professor Mau to say that in preparing his manuscript for English readers I have, with his permission, made some changes. The order of presentation has occasionally been altered. In several chapters the German manuscript has been abridged, while in others, containing points in regard to which English readers might desire a somewhat fuller statement, I have made slight additions. The preparation of the English form of the volume, undertaken for reasons of friendship, has been less a task than a pleasure. FRANCIS W. KELSEY. ANN ARBOR, MICHIGAN, October 25, 1899. PREFACE TO THE SECOND EDITION The author and the translator unite in expressing their deep appreciation of the kind reception accorded to the first edition of this book. The second edition has been revised on the spot. Besides minor additions, it has been enlarged by a chapter on the recently discovered temple of Venus Pompeiana, and a Bibliographical Appendix; prepared in response to requests from various quarters. Among the new illustrations in the text are a restoration of the temple of Vespasian and a reproduction of the bronze youth found in 1900, besides the Alexandria patera and one of the skeleton cups from the Boscoreale treasure; in Plate VIII are presented two additional paintings from the house of the Vettii.
