_Eusebius_, _H. E._ II. xiv., gives a definite date for the first coming of Peter to Rome, and his preaching there. The historian was describing the influence of Simon Magus at Rome. This, he adds, did not long continue, “for immediately under the reign of Claudius, by the benign and gracious providence of God, Peter, that powerful and great apostle who by his courage took the lead of all the rest, was conducted to Rome against this pest of mankind. He (S. Peter) bore the precious merchandise of the revealed light from the East to those in the West, announcing this light itself, and salutary doctrine of the soul, the proclamation of the kingdom of God.” _Eusebius_ also writes that “Linus, whom he (Paul) has mentioned in his Second Epistle to Timothy as his companion at Rome, has been before shown to have been the first after Peter that obtained the Episcopate at Rome.”--Eusebius, _H. E._ III. iv. * * * * * The _traditional_ memories of Peter’s residence in Rome and his prolonged teaching there are very numerous. De Rossi while quoting certain of these as legendary, adds that an historical basis underlies these notices. Some of the more interesting of these are connected with the house and family of Pudens on the Aventine, and with the cemetery of Saint Priscilla on the Via Salaria. To the pilgrims of the fifth and following centuries were pointed out the chair in which Peter used to sit and teach (Sedes ubi prius sedit S. Petrus), and also the cemeterium fontis S. Petri--cemeterium ubi Petrus baptizaverat. Marucchi, the pupil and successor of De Rossi, believes that this cemetery where it was said S. Peter used to baptize, is identical with parts of the vast and ancient catacomb of Priscilla. These and further traditional notices are dwelt on with greater detail presently when the general evidence is summed up.[4] II A SUMMARY OF LITERARY NOTICES And now to sum up the evidence we have been quoting: The _Literary Notices_ have been gathered from all parts of the Roman world where Christianity had made a lodgment. From _Rome_ (Clement of Rome) in the first and second centuries and early in the third century. From _Antioch_ (Ignatius, Papias) (including Syria and Asia Minor) very early in the second century. From _Corinth_ (Greece) (Dionysius) in the second half of the second century. From _Lyons_ (Gaul) (Irenæus) in the second half of the second century. From _Alexandria_ (Egypt) (Clement of Alexandria) in the second half of the second century. From _Carthage_ (North Africa) (Tertullian) in the close of the second century.
