We need not say any more to show how important is the addition to our Catholic Biblical literature made by F. Vercellone. II. _S. Pietro in Roma, etc. St. Peter in Rome_, or the historical truth of St. Peter's journey to Rome, proved against a recent assailant. By John Perrone, S.J. Rome: Tipografia Forense, 1864--1 vol. 8vo, pag. 168. Any new work by Father Perrone is sure to be received with respect and attention. The assailant, whose attack on the historical truth of St. Peter's journey to Rome is refuted in this book, is the author of an anonymous treatise published at Turin in 1861, entitled _The historical impossibility of St. Peter's journey to Rome demonstrated, by substituting the true for the false tradition_. In an introduction, headed "The Protestants in Italy", Father Perrone laments the great mischief they have done to his country, and at the same time expresses his hopes that their attempts at proselytism will end in failure. He commences by an examination of the statements made by his adversary, to the effect that even Catholic writers of the highest authority had denied St. Peter's presence in Rome, that it is proved from the sacred Scriptures that St. Peter could not have come to Rome either in the time of Claudius or in that of Nero, and that, therefore, he could not have been there at all. In reply, F. Perrone proves that no Catholic author has ever denied St. Peter's journey to Rome; that we neither can nor ought to expect from Sacred Scripture a history of the journey in question, but only a proof that it was possible; and that, because the precise year of the event is not known, it does not follow that the event itself could never have taken place. He then proceeds to develope the arguments which prove the Prince of the Apostles to have been at Rome. 1^o, from the writers of the first three centuries, and then from those of the fourth; 2^o, from the monuments existing at Rome, sarcophagi, figured glasses from the Catacombs (one of which he illustrates at great length), inscriptions, and spots ever held sacred at Rome to the memory of St. Peter; 3^o, from the pilgrimages made to his shrine by Christians from every portion of the Church during the first three centuries; and 4^o, from the catalogues of the Roman Pontiffs drawn up by writers of the early ages. In the next two chapters he defends the authority of several of the fathers from the ignorant and malicious misrepresentations of his adversary, and crowns the work by reprinting at the end of his volume a dissertation delivered by him some years ago in one of the Roman academies, in which he proves that "the love and the hatred men show to Rome are two consequences of the presence, the episcopate, and the martyrdom of St. Peter in the Eternal City".
