"Then the proconsul, according to the imperial command, bound the blessed John the Apostle with chains, and brought him with him to Rome, and announced his arrival to Domitian, who, being indignant, gave command to the proconsul that the holy John should be placed in a boiling caldron, in presence of the senate, in front of the gate which is called the Latin Gate, when he had been scourged, which was done. But, by the grace of God protecting him, he came forth uninjured and exempt from corruption of the flesh. And the proconsul, being astonished that he had come forth from the caldron anointed but not scorched, was desirous of restoring him to liberty, and would have done so if he had not feared to contravene the royal command. And when tidings of these things had been brought to Domitian, he ordered the holy Apostle John to be banished to the island called Patmos, in which he saw and wrote the Apocalypse, which bears his name, and is read by us." THE TOMB OF LUTATIUS CATULUS is a lofty concrete tomb of the time of the republic, on the left, near the Church of S. John. This may be the general who ended the First Punic War, 242 B.C., or his descendant consul, 102 B.C., proscribed by Marius, and who suffocated himself with charcoal fumes. _Behind the round chapel is_ THE COLUMBARIA OF HYLAS AND VITALINE. The columbaria were underground chambers, containing niches in the walls, in which were placed the urns containing the ashes of those who were burned. As the niche was like a dove's nest in shape, it was called a "columbarium," the whole tomb a "columbaria." This one was discovered by the Marchese Campana, and is carefully preserved. Here were buried the freedmen of Augustus while Hylas and Vitaline were the custodians. _Returning to the Via Appia_, the second gate on the left admits to the CHAPEL OF THE SEVEN SLEEPERS, dedicated to S. Gabriel and the Sleepers of Ephesus. It was decorated in fresco by the same Beno and Maria de Rapiza who did the frescoes in S. Clement's towards the end of the eleventh century. Beyond, a tall cypress tree marks the entrance to the (No. 13) TOMB OF THE SCIPIOS. The vaults, hewn in the tufa, with the traces of a cornice over the entrance arch, and the stump of a Doric column, are all that now remain. The tomb was discovered in 1780; and the bones of the consul, found in good preservation, were carried to Padua, where they were interred by Senator Quirini. Six sarcophagi were found, and several recesses for more bodies; the original inscriptions were removed to the Vatican and placed in the vestibule of the Belvedere. Lucius Scipio Barbatus, his son; Aula Cornelia, wife of Cneius Scipio Hispanus, a son of Scipio Africanus, senior; Lucius Cornelius, son of Asiaticus; Cornelius Scipio Hispanus and his son Lucius, were buried here. Africanus senior was buried at Liternum. From this tomb we can ascend into a brick tomb of the second century. TOMB OF CORNELIUS TACITUS.
