Before leaving the Vatican let me answer a doubt which may naturally have occurred to the mind of the reader, as it has long perplexed the author. After the many vicissitudes to which the place has been subject, from the time of Elagabalus to the pillage of the constable de Bourbon, can we be sure that the body of the founder of the Roman Church is still lying in its grave under the great dome of Michelangelo, under the canopy of Urban VIII., under the high altar of Clement VIII.? After considering the case from its various aspects, and weighing all the circumstances which have attended each of the barbaric invasions, I cannot see any reason why we should disbelieve the popular opinion. The tombs of S. Peter and S. Paul have been exposed but once to imminent danger, and that happened in 846, when the Saracens took possession of their respective churches and plundered them at leisure. Suppose the crusaders had taken possession of Mecca: their first impulse would have been to wipe the tomb of the Prophet from the face of the earth, unless the keepers of the Kaabah, warned of their approach, had time to conceal or protect the grave by one means or another. Unfortunately, we know very little about the Saracenic invasion of 846; still it seems certain that Pope Sergius II. and the Romans were warned days or weeks beforehand of the landing of the infidels, by a despatch from the island of Corsica. Inasmuch as the churches of S. Peter and S. Paul were absolutely defenceless, in their outlying positions, I am sure that steps were taken to conceal or wall in the entrance to the crypts and the crypts themselves, unless the tombs were removed bodily to shelter within the city walls. An argument, very little known but of great value, seems to prove that the relics were saved.
The "Liber Pontificalis" describes, among the gifts of Constantine, a cross of pure gold, weighing one hundred and fifty pounds, which he placed over the gold lid of the coffin. The golden cross bore the following inscription in niello work, "Constantine the emperor and Helena the empress have richly decorated this royal crypt, and the basilica which shelters it." If this precious object is there, the remains must a fortiori be there also. Here comes the decisive test. In the spring of 1594, while Giacomo della Porta was levelling the floor of the church above the Confession, removing at the same time the foundations of the Ciborium of Julius II., the ground gave way, and he saw through the opening what nobody had beheld since the time of Sergius II.,—the grave of S. Peter,—and upon it the golden cross of Constantine. On hearing of the discovery, Pope Clement VIII., accompanied by cardinals Bellarmino, Antoniano, and Sfrondato, descended to the Confession, and with the help of a torch, which Giacomo della Porta had lowered into the hollow space below, could see with his own eyes and could show to his followers the cross, inscribed with the names of Constantine and Helena. The impression produced upon the Pope by this wonderful sight was so great that he caused the opening to be closed at once. The event is attested not only by a manuscript deposition of Torrigio, but also by the present aspect of the place. The materials with which Clement VIII. sealed the opening, and rendered the tomb once more invisible and inaccessible, can still be seen through the "cataract" below the altar.
THE TWO BASILICAS OF S. PAUL
The original structure of Constantine in black, that of Theodosius and Honorius shaded
Wonder has been manifested at the behavior of Constantine towards S. Paul, whose basilica at the second milestone of the Via Ostiensis appears like a pigmy structure in comparison to that of S. Peter. Constantine had no intention of placing S. Paul in an inferior rank, or of showing less honor to his memory. He was compelled by local circumstances to raise a much smaller building to this apostle. As before stated, there were three rules which builders of sacred memorial edifices had to observe: first, that the tomb-altar of the saint in whose honor the building was to be erected should not be molested or moved from its original place either vertically or horizontally; second, that the edifice should be adapted to the tomb so as to give it a place of honor in the centre of the apse; third, that the apse and the front of the edifice should look towards the east. The position of S. Peter's tomb in relation to the circus of Nero and the cliffs of the Vatican was such as to give the builders of the basilica perfect freedom to extend it in all directions, especially lengthwise. This was not the case with that of S. Paul, which was only a hundred feet distant from an obstacle which could not be overcome,—the high-road to Ostia, the channel by which the city of Rome was fed. The road to Ostia ran east of the grave; hence the necessity of limiting the size of the church within these two points. Discoveries made in 1834, when the foundations of the present apse were strengthened, and again in 1850, when the foundations of the baldacchino of Pius IX. were laid,[87] have enabled Signor Paolo Belloni, the architect, to reconstruct the plan of the original building of Constantine. His memoir[88] is full of useful information well illustrated. One of his illustrations, representing the comparative plans of the original and modern churches, is here reproduced.
The plan needs no comment, but one particular cannot be omitted. In the course of the excavations for the baldacchino, the remains of classical columbaria were found a few feet from the grave of the apostle, with their inscriptions still in place. He must, therefore, have been buried, like S. Peter, in a private area, surrounded by pagan tombs.
In 386 Valentinian, Theodosius, and Arcadius asked Flavius Sallustius, prefect of the city, to submit to the Senate and the people a scheme for the reconstruction a fundamentis of the basilica, so as to make it equal in size and beauty to that of the Vatican. To fulfil this project, without disturbing either the grave of the apostle or the road to Ostia, there was but one thing to do; this was to change the orientation of the church from east to west, and extend it at pleasure towards the bank of the Tiber. The consent of the S. P. Q. R. was easily obtained, and the magnificent temple, which lasted until the fire of July 15, 1823, was thus raised so as to face in a direction opposite to the usual one.
