The second-century Pope Anicetus, wishing to demonstrate that he spoke with the authority of Peter, reported that Peter had travelled to Rome to lead the congregation there, and had been beheaded in Rome. A century later, Origen changed this to say that Peter was sentenced to crucifixion but, feeling unworthy of being crucified like Jesus, asked to be crucified upside down.
Taken literally, this made Peter the first real leader of the Christians in Rome and thus the predecessor of the Catholic pope. Although the evidence is that the role of bishop was only created in the second century, a tradition also arose that Peter was the first bishop of Rome, and a line of bishops was defined, leading from Peter through the remainder of the first century to Clement at the end of the century and onwards to Anicetus later in the second century. Interestingly, Clement of Rome did mention Peter in his epistle, 1 Clement, but seems to have been unaware that Peter ever visited Rome.
