The Cemetery of Generosa, on the road to Porta, is not alluded to in the Pilgrim Guides, no doubt owing to its distance—some five miles—from the city. Lanciani gives a vivid description of its story and of its discovery in 1867. It is of small extent, and apparently was excavated in the persecution of Diocletian, circa A.D. 303, in what was once a sacred grove belonging to the College of the Arval Brothers, but which had been abandoned, probably after the dissolution of the Brotherhood, which is supposed to have taken place about the middle of the third century.

The Via Ostiensis
The Via Ostiensis, on the city side of the Tiber, one of the principal roads of the Empire, begins at the ancient Porta Ostiensis, known from the sixth century onwards as the Porta S. Pauli, and leads to the old harbour of Ostia. The Pilgrim Itineraries enumerate three cemeteries as situated hard by this road—the tomb of the Apostle S. Paul with the little Cemetery of Lucina, the Cemetery of Commodilla, and that of S. Theckla.
(1) According to a very general tradition, S. Paul suffered martyrdom, A.D. 67, and his body was laid in a tomb on the Ostian Way in a garden belonging to a Christian lady named Lucina,—some identify her with the “Lucina” of the Cemetery of Callistus on the Appian Way. There it rested, according to the most recent investigations, until the persecution and confiscation of the cemeteries in A.D. 258, when for security’s sake it was secretly removed at the same time as the body of S. Peter was brought from the grave on the Vatican Hill. The sacred remains of the two apostles were laid in the “Platonia” Crypt, in what was subsequently known as the Catacomb of S. Sebastian, on the Via Appia; and probably after an interval of some two years, when the cemeteries were restored to the Christian congregations by the Emperor Gallerius, the bodies of the two apostles were brought back again to their original resting-places.
Anacletus, the third in succession of the Roman bishops, erected in the first century a small “Memoria” or chapel over the tomb of S. Paul, like the one he built over the tomb of S. Peter on the Vatican Hill.
In the year 324–5 the first Christian Emperor, Constantine, over the apostle’s tomb and little “Memoria,” caused the first important basilica, known as S. Paul’s, to be erected; the Emperor treated the loculus or sarcophagus of S. Paul in the same manner as he had treated the sarcophagus of S. Peter, enclosing it in a solid bronze coffin, on which he laid a cross of gold. When the basilica was rebuilt, after the fire of A.D. 1813, a marble slab, which apparently was a part of the vaulted roof of the original sepulchral chamber of the apostle, came to light. On this slab, or rather slabs of marble, which now lie directly under the altar, are engraved the simple words Pavlo Apostolo Mart: the inscription evidently dating from the days of Constantine (A.D. 324–5). No further investigation of the tomb was permitted. It is believed that the bronze sarcophagus with its sacred contents, with the golden cross, lie immediately under the solid masonry upon which the slab of marble we have been speaking of rests.
On the slab of marble in question, besides the simple inscription above quoted, are three apertures: the most important of these is circular; it is, in fact, a little well, and is 23½ inches in depth, and was no doubt originally what is termed the “billicum confessionis,” through which handkerchiefs and other objects were lowered, so as to be hallowed by resting for a brief space on the sarcophagus when access to the vault itself was not permitted. The other two apertures or little wells are only 12½ and 8 inches deep respectively. It is not known for what purpose these two were intended.
The history of the famous basilica is as follows. Lanciani writes how “wonder has been manifested at the behaviour of Constantine the Great towards S. Paul, whose basilica at the second milestone of the Via Ostiensis appears like a pigmy structure in comparison with that which he erected over the tomb of S. Peter. Constantine had no intention of placing S. Paul in an inferior rank, or of showing less honour to his memory.” In his original design which he carried out, the high road to Ostia ran close by the grave; thus the space at his disposal was limited. But before the fourth century had run out it was imperatively felt that the Church of S. Paul ought to be equal in size and beauty to that on the Vatican Hill: so, in rebuilding the basilica the original plan was changed by the Emperor Valentinian II., in A.D. 386. The tomb and the altar above it were left undisturbed, a great arch was raised above the altar, and westwards from that point, in the direction of the Tiber, a vast church was built. The great work was continued by Theodosius and completed by Honorius, and the splendid decorative work finally carried out by Honorius’ sister, the famous Placidia, who died in A.D. 450. Certain Popes, notably Gregory the Great, and later Honorius III, in A.D. 1226, added to the decorations of Placidia.
There was evidently in very early times a cemetery around the crypt which contained the body of S. Paul; this was the original Cemetery of Lucina. But it has been disturbed by the subsequent erection of the Basilica of Constantine, and later by the far larger church begun under Valentinian II. It is hoped that a future careful exploration of the cemetery will bring to light much that is at present unknown.
