The excavation of the Cemetery of S. Callixtus, which was begun in 1854, and was carried on with great care by De Rossi, led to the clearing out of a crypt in which the early Bishops of Rome had been laid. The bodies had been removed when Paschal I. conveyed so many of those of the saints and martyrs into Rome, on account of the ruin into which the Catacombs had fallen, but their epitaphs remained, all of the third century, and in Greek; among these, that of Urbanus, 230; and it was perhaps precisely this fact which led the recomposer of the Acts to confound the Urban of S. Cæcilia’s time with the Pope. The first Pope known to have been laid there was Zephyrinus, in 218. Here also was found an inscription set up by Damasus I., recording how that the bodies of bishops and priests, virgins and confessors lay in that place.

Now by a narrow, irregular opening in the rock, entrance is obtained to a further chamber, about twenty feet square, lighted by a luminare in the top, or an opening to the upper air cut in the tufa. This, there can be no manner of doubt, is the crypt in which reposed the body of S. Cæcilia.

In the Acts it was said to adjoin that in which were laid the Bishops of Rome; though, as these bishops were of later date than Cæcilia, if we take her death to have been in 177, their crypt must have been dug out or employed for the purpose of receiving their bodies at a later period.

Again, it is an interesting fact, that here a number of the tombstones that have been discovered bear the Cæcilian name, showing that this cemetery must have belonged to that gens or clan. Not only so, but one is inscribed with that of Septimus Prætextatus Cæcilianus, a servant of God during thirty years. It will be remembered that Prætextatus was the name of the brother of Valerian, who was betrothed to Cæcilia, and it leads one to suspect that the families of Valerian and of Cæcilia were akin.

The chapel or crypt contains frescoes. In the luminare is painted a female figure with the hands raised in prayer. Beneath this a cross with a lamb on each side. Below are three male figures with the names Sebastianus, Curinus (Quirinus), and Polycamus. Sebastian is doubtless the martyr of that name whose basilica is not far off. Quirinus, who has the corona of a priest, is the bishop and martyr of Siscia, whose body was brought in 420 to Rome. Of Polycamus nothing is known, save that his relics were translated in the ninth century to S. Prassede.

Against the wall lower down is a seventh-century representation of S. Cæcilia, richly clothed with necklace and bracelets; below a head of Christ of Byzantine type, and a representation of S. Urban. But these paintings, which are late, have been applied over earlier decoration; behind the figure of S. Cæcilia is mosaic, and that of Christ is painted on the old porphyry panelling. There are in this crypt recesses for the reception of bodies, and near the entrance an arched place low enough to receive a sarcophagus; and there are traces as though the face had at one time been walled up.

The walls are covered with graffiti, or scribbles made by pilgrims. An inscription also remains, to state that this was the sepulchre of S. Cæcilia the Martyr, but this inscription is not earlier than the ninth or tenth century.

In 817 Paschal I. was Pope, and in the following year he removed enormous numbers of the remains of martyrs from the Catacombs into the churches of Rome, because the condition into which these subterranean cemeteries were falling was one of ruin. They had been exposed to the depredations of the Lombards, and then to decay. Some had fallen in, and were choked.

Precisely this Catacomb had been plundered by the Lombard king, Astulf, and it was not known whether he had carried off the body of S. Cæcilia or not. All those of the former popes Paschal removed.

In 844, however, Paschal pretended that he had seen S. Cæcilia in a dream, who had informed him that she still lay in her crypt in the Catacomb of S. Callixtus. No reliance can be placed on the word of a man so unprincipled as Paschal. At this very time two men of the highest rank, who were supporters of Louis the Pious, the Emperor, had been seized, dragged to the Lateran Palace, their eyes plucked out, and then beheaded. The Pope was openly accused of this barbarous act. The Emperor sent envoys to examine into it, but Paschal threw all sorts of difficulties in their way. He refused to produce the murderers; he asserted that they were guilty of no crime in killing these unfortunate men, and he secured the assassins by investing them with a half-sacred character as servants of the Church of S. Peter. Himself he exculpated from all participation in the deed by a solemn, expurgatorial oath. Such was the man who pretended to visions of the saints. His dream was an afterthought. In the clearing out of the crypt of S. Cæcilia, the wall that had closed the grave was broken through, and the cypress chest was disclosed. Whereupon Paschal promptly declared he had dreamt that so it would be found. The body was found in the coffin, incorrupt, and at its feet were napkins rolled together and stained with blood.
