Hence we return to the corridor of the Grotte Nuove, containing a number of mosaics and statues detached from different papal tombs, the best being those from that of Nicholas V. and that of Paul II., by Mino da Fiesole (a figure of Charity is especially beautiful), and a bas-relief of the Virgin and Child, by Arnolfo, from the tomb of Benedict VIII.

Here also are a half-length statue of Boniface VIII., ascribed to Andrea Pisano; a half-length of Benedict XII., by Paolo di Siena; and a figure of St. Peter seated on a gothic throne which once supported a statue of Benedict XII.

The Chapel of St. Longinus has a mosaic from a picture by Andrea Sacchi. Near the entrance of the shrine are marble reliefs of the martyrdoms of St. Peter and St. Paul. Opposite to the entrance of the shrine is the magnificent sarcophagus of Junius Bassus, Christian prefect of Rome, who died A.D. 359. It was discovered near its present site in 1595. It is adorned with admirable sculptures from the Old and New Testament.

Opening from the centre of the circular passage is the Confession or Shrine of SS. Peter and Paul, which contains the sarcophagus brought from the Catacomb near S. Sebastiano in 257, and which the Roman Catholic Church has always revered as that of St. Peter. On the altar, consecrated in 1122, are two ancient pictures of St. Peter and St. Paul. Only half the bodies of the saints are held to be preserved here, the other portion of that of St. Peter being at the Lateran, and of St. Paul at S. Paolo fuori Mura.

To the Roman Catholic mind this is naturally one of the most sacred spots in the world, since it holds literally the words of St. Ambrose, that: "Where Peter is, there is the Church,—and where the Church is, there is no death, but life eternal."[340]

"From this place Peter, from this place Paul, shall be caught up in the resurrection. Oh consider with trembling that which Rome will behold, when Paul suddenly rises with Peter from this sepulchre, and is carried up into the air to meet the Lord."—St. John Chrysostom, Homily on the Ep. to the Romans.

"Among the cemeteries ascribed by tradition to apostolic times, the crypts of the Vatican would have the first claim on our attention, had they not been almost destroyed by the foundations of the vast basilica which guards the tomb of St. Peter.... The Liber Pontificalis says that Anacletus, the successor of Clement in the Apostolic See, 'built and adorned the sepulchral monument (construxit memoriam) of blessed Peter, since he had been ordained priest by St. Peter, and other burial-places where the bishops might be laid.' It is added that he himself was buried there; and the same is recorded of Linus and Cletus, and of Evaristus, Sixtus I., Telesphorus, Hyginus, Pius I., Eleutherius, and Victor, the last of whom was buried A.D. 203; and after St. Victor, no other pontiff is recorded to have been buried at the Vatican until Leo the Great was laid in St. Peter's, A.D. 461. The idea conveyed by the words construxit memoriam is that of a monument above-ground according to the usual Roman custom; and we have seen that such a monument, even though it covered the tomb of Christian bishops, would not be likely to be disturbed at any time during the first or second century. For the reason we have already stated, it is impossible to confront these ancient notices with any existing monuments. It is worth mentioning, however, that De Rossi believes that the sepulchre of St. Linus was discovered in this very place early in the seventeenth century, bearing simply the name of Linus."—Northcote and Brownlow, Roma Setterranea.

To ascend the Dome of St. Peter's requires a special order. The entrance is from the first door in the left aisle, near the tomb of Maria-Clementina Sobieski. The ascent is by an easy staircase à cordoni, the walls of which bear memorial tablets of all the royal personages who have ascended it. The aspect of the roof is exceedingly curious from the number of small domes and houses of workmen with which it is studded,—quite a little village in themselves. A chamber in one of the pillars which support the dome contains a model of the ancient throne of St. Peter, and a model of the church, by Michael Angelo and his predecessor, Antonio di Sangallo. The dome is 300 feet above the roof, and 613½ feet in circumference. An iron staircase leads thence to the ball, which is capable of containing sixteen persons.

"Cette hauteur fait frémir," dit Beyle, "quand on songe aux tremblements de terre qui agitent fréquemment l'Italie, et qu'un instant peut vous priver du plus beau monument qui existe. Certainement jamais il ne serait relevé: nous sommes trop raisonables."

"De Brosse raconte que deux moines espagnoles, qui se trouvaient dons la boule de St. Pierre lors de la secousse de 1730, eurent une telle peur, que l'un d'eux mourut sur la place."—A. Du Pays.
