For the lives of these two great Apostles, we can only recommend a reading of the entire New Testament, which contains accounts of their lives and many of their inspired writings. St Peter, after preaching in Judea, Antioch and parts of Asia, came to Rome, where he was crucified by order of the Emperor Nero, about the year 66. Being led to the cross, he begged the executioner to crucify him upside-down, because he felt unworthy to partake of the same death as the Savior.
  St Paul's apostolic labors extended from Arabia to Spain. He also ended his earthly course in Rome, beheaded by order of Nero, some say at the same time that St Peter was crucified.
