The repairs must have been made in haste, between March, 537, the date of the flight of Vitiges, and the following November, the date of the journey of Virgilius to Constantinople, from which he never returned. Traces of this Pope's restorations have been found in other catacombs. In those of Callixtus the fragments of a tablet, dedicated by Damasus to S. Eusebius, have been found, dispersed over a large area, and also a copy set up by Virgilius in the place of the original. In those of Hippolytus, on the Via Tiburtina, an inscription was discovered in 1881, which stated that the "sacred caverns" had been restored _præsule Virgilio_. The example of Virgilius and his successors in the See of Rome was followed by private individuals. The tomb of Crysanthus and Daria on the Via Salaria was restored, after the retreat of the barbarians, _pauperis ex censu_, that is to say, with the modest means of a devotee. Nibby has attributed the origin of cemeteries within the walls to the invasion of Vitiges, burial within the city limits having been strictly forbidden by the laws of Rome. But the law seems to have been practically disregarded even before the Gothic wars. Christians were buried in the Prætorian camp, and in the gardens of Mæcenas, during the reign of Theodoric (493-526). I have mentioned this particular because it marks another step towards the abandonment of suburban cemeteries. The country around Rome having become insecure and deserted, it was deemed necessary to place within the protection of the city walls the bodies of martyrs who had been buried at a great distance from the gates. The first translation took place in 648: the second in 682, when the bodies of Primus and Felicianus were removed from Nomentum, and those of Viatrix, Faustinus and Simplicius from the _Lucus Arvalium_ (Monte delle Piche, by la Magliana). The last blow to the catacombs was given by Paschal I. (817-824). Contemporary documents mention innumerable transferences of bodies. The mosaic legend of the apse of S. Prassede says that Pope Paschal buried the bodies of many saints within its walls.[152] The official catalogue of the remains removed on July 20, 817, which was compiled by the Pope's notary and engraved on marble, has come down to us. It speaks of the translation of twenty-three hundred bodies, most of which were buried under the chapel of S. Zeno, which Paschal I. had built as a memorial to his mother, Theodora Episcopa. The legend in the apse of S. Cæcilia speaks, likewise, of the transference to her church of bodies "which had formerly reposed in crypts" (_quæ primum in cryptis pausabant_): among them those of Cæcilia herself, Valerianus, Tiburtius, and Maximus. The finding and removal of Cæcilia's remains from the Catacombs of Callixtus is one of the most graceful episodes in the life of Paschal I. He describes it at length in a letter addressed to the people of Rome.
