When the crucifixion of St. Peter and the decollation of St. Paul are represented together in the same picture, such a picture must be considered as religious and devotional, not historical; it does not express the action as it really occurred, but, like many pictures of the crucifixion of our Saviour, it is placed before us as an excitement to piety, self-sacrifice, and repentance. We have this kind of treatment in a picture by Niccolò dell’ Abate:[204] St. Paul kneels before a block, and the headsman stands with sword uplifted in act to strike; in the background, two other executioners grasp St. Peter, who is kneeling on his cross and praying fervently: above, in a glory, is seen the Virgin; in her arms the Infant Christ, who delivers to two angels palm-branches for the martyred saints. The genius of Niccolò was not precisely fitted for this class of subjects. But the composition is full of poetical feeling. The introduction of the Madonna and Child stamps the character of the picture as devotional, not historical—it would otherwise be repulsive, and out of keeping with the subject. There is a Martyrdom of St. Peter and St. Paul engraved after Parmigiano,[205] which I shall notice on account of its careless and erroneous treatment. They are put to death together; an executioner prepares to decapitate St. Peter, and another drags St. Paul by the beard: the incidents are historically false, and, moreover, in a degraded and secular taste. These are the mistakes that make us turn disgusted from the technical facility, elegance, and power of the sixteenth century, to the simplicity and reverential truth of the fourteenth. * * * * * There are various traditions concerning the relics of St. Peter and St. Paul. According to some, the bodies of the two apostles were, in the reign of Heliogabalus, deposited by the Christian converts in the catacombs of Rome, and were laid in the same sepulchre. After the lapse of about two hundred years, the Greek or Oriental Christians attempted to carry them off; but were opposed by the Roman Christians. The Romans conquered; and the two bodies were transported to the church of the Vatican, where they reposed together in a magnificent shrine, beneath the church. Among the engravings in the work of Ciampini and Bosio are two rude old pictures commemorating this event. The first represents the combat of the Orientals and the Romans for the bodies of the Saints; in the other, the bodies are deposited in the Vatican. In these two ancient representations, which were placed in the portico of the old basilica of St. Peter, the traditional types may be recognised—the broad full features, short curled beard, and bald head of St. Peter, and the oval face and long beard of St. Paul. * * * * *
