Quo Vadis by Henryk Sienkiewicz — Read

At last the hour was accomplished for both Apostles. But, as if to complete his service, it was given to the fisherman of the Lord to win two souls even in confinement. The soldiers, Processus and Martinianus, who guarded him in the Mamertine prison, received baptism. Then came the hour of torture. Nero was not in Rome at that time. Sentence was passed by Helios and Polythetes, two freedmen to whom Caesar had confided the government of Rome during his absence.

On the aged Apostle had been inflicted the stripes prescribed by law; and next day he was led forth beyond the walls of the city, toward the Vatican Hill, where he was to suffer the punishment of the cross assigned to him. Soldiers were astonished by the crowd which had gathered before the prison, for in their minds the death of a common man, and besides a foreigner, should not rouse such interest; they did not understand that that retinue was composed not of sightseers, but confessors, anxious to escort the great Apostle to the place of execution. In the afternoon the gates of the prison were thrown open at last, and Peter appeared in the midst of a detachment of pretorians. The sun had inclined somewhat toward Ostia already; the day was clear and calm. Because of his advanced age, Peter was not required to carry the cross; it was supposed that he could not carry it; they had not put the fork on his neck, either, so as not to retard his pace. He walked without hindrance, and the faithful could see him perfectly.
