Behind | The Death of Peter in Christian Tradition

A number of early Christians mention the death of Peter, but one of the most complete accounts comes from the Latin Father Jerome (AD 340-420), in his work called On Illustrious Men:

Simon Peter the son of John, from the village of Bethsaida in the province of Galilee, brother of Andrew the apostle, and himself chief of the apostles, after having been bishop of the church of Antioch and having preached to the Dispersion—the believers in circumcision, in Pontus, Galatia, Cappadocia, Asia and Bithynia—pushed on to Rome in the second year of Claudius to overthrow Simon Magus, and held the sacerdotal chair there for twenty-five years until the last, that is the fourteenth, year of Nero. At his hands he received the crown of martyrdom being nailed to the cross with his head towards the ground and his feet raised on high, asserting that he was unworthy to be crucified in the same manner as his Lord. He wrote two epistles which are called Catholic, the second of which, on account of its difference from the first in style, is considered by many not to be by him. Then too the Gospel according to Mark, who was his disciple and interpreter, is ascribed to him. On the other hand, the books, of which one is entitled his Acts, another his Gospel, a third his Preaching, a fourth his Revelation, a fifth his Judgment are rejected as apocryphal.

Buried at Rome in the Vatican near the triumphal way he is venerated by the whole world.
