The Via Labicana
Leads from the Porta Maggiore, the ancient Porta Prænestina, to Palestrina. The Itineraries tell us of two cemeteries on this road, that of S. Castulus and that of SS. Peter and Marcellinus. The Catacomb of S. Castulus has only been very partially examined. It is in a ruinous condition, and is not at present accessible. S. Castulus suffered martyrdom in the persecution of Diocletian.
The Catacomb of SS. Peter and Marcellinus, sometimes called “ad duas lauros,” from the original name of the district, is in the immediate neighbourhood of the famous Torre Pignatara, the tomb of S. Helena, this appellation being derived from the pignatte or earthen pots used in the building. The magnificent porphyry sarcophagus now in the Vatican was removed from this tomb. SS. Peter and Marcellinus, from whom this once celebrated catacomb is named, suffered in the persecution of Diocletian. S. Peter was in orders as an exorcist. S. Marcellinus was a priest. Pope Damasus, in his inscription originally placed on their crypt, tells us he learned the particulars of their martyrdom from the executioner employed by the State. This cemetery has lately been partially explored. The bodies of the two saints who gave their names to the catacomb were carried away, and are now in Seligenstadt, near Mayence. The saints termed “the Quatuor Coronati” were in the first instance buried here, but their remains were subsequently translated by Pope Leo IV to the church on the Cœlian. This cemetery is of considerable extent.
The Itineraries enumerate the names of several martyrs once evidently well known. They also speak of many other martyrs buried here, using such expressions as “innumerabilis martyrum multitudo sepulta jacent”—“alii (Martyres) innumerabiles,” etc.
The Via Tiburtina
The Via Tiburtina leads to Tivoli. It quits Rome by the Porta S. Lorenzo, which stands on the site of the ancient Porta Tiburtina. On this road are two large cemeteries, that of S. Cyriaca and that of S. Hippolytus. S. Cyriaca was a Christian widow. The importance, however, of this catacomb is mainly derived from its possessing the tomb of S. Laurence. S. Laurence suffered martyrdom A.D. 258, three days after the death of Pope Sixtus II, to whom he was attached as deacon. A very general tradition relates that Laurence suffered on a gridiron. An extraordinary popularity is attached to his memory. Marucchi, one of the latest scholars who has written on the catacombs, does not hesitate to say that the veneration paid to him was almost equal that accorded to the apostles. There is scarcely a city in Western Christendom which does not possess a church bearing his honoured name. In Rome itself there are six of these.
Over the crypt containing the tomb of S. Laurence, Constantine the Great built a little oratory or memoria, which soon became too small for the crowds of pilgrims. A second church was erected by Pope Sixtus III, A.D. 432, by the side of Constantine’s Memoria which was ever known as “Basilica ad Corpus.” The second church was termed the “Basilica Major.” Three of the fifth century Popes of Rome were buried in the “Basilica ad Corpus.” In the thirteenth century the two churches were made into one by Honorius III, A.D. 1218.
The Itineraries mention several well-known martyrs buried in the cemetery which was excavated round the martyr’s sacred tomb, notably SS. Justus, Cyriaca, Simferosa, etc., “cum multis martyribus.” The catacomb in comparatively modern times has been ruthlessly damaged by the works in connection with a very large modern cemetery. Only since A.D. 1894 has more care been taken in the preservation of the precious remains of this once important catacomb.
Cemetery of S. Hippolytus.—On the same great road, the Via Tiburtina which stretches across the now desolate Campagna to Tivoli, on the northern side of the road almost opposite the Cemetery of S. Cyriaca on which stands the Basilica of S. Laurentius just described, is the Catacomb of S. Hippolytus. It is only comparatively recently that this cemetery has been really explored, and much still remains to be excavated here. A small basilica underground was discovered, with the historic crypt in which the once famous martyr was buried. The corridors around have been sadly ravaged again and again by barbarian invaders in the fifth and following centuries, and the whole catacomb is in ruin, and has been only in part investigated. It is evidently of considerable extent. Proximity to the tomb of the great scholar martyr was evidently a privilege eagerly sought by many from the middle years of the third century onward. The numbers of Pilgrim “Graffiti” or inscriptions more or less roughly carved and painted in the neighbourhood of the sanctuary, tell us that the spot where the remains of Hippolytus lay, was long the object of reverent pilgrimage after the Peace of the Church all through the fourth and following centuries. The Itineraries mention many martyrs buried here, among whom S. Genesius is perhaps the best known; he was a celebrated actor; once a mocker at the religion of which eventually he became the brave confessor; he died for his faith.
