The remains of S. Hyacinthus were found as late as 1841 in a closed loculus and wrapped in a cloth which still emitted a sweet perfume. The bones had evidently been burned. It has been suggested that probably the martyr had suffered by fire; this was an unusual form of martyrdom. The name of the saint and date of the deposition and the word Martyr were on the loculus. The inscription and the hallowed remains are now in the Church of the Propaganda.
Probably further investigation will be made in this interesting but ruined Catacomb. Researches here, however, are difficult and dangerous. Much of the work of Damasus in the later part of the fourth century has been recognized in this place. This cemetery was apparently held in high estimation by the earlier pilgrims.
The Itineraries speak of another cemetery on the Via Salaria Vetus under the name of “ad Clivum Cucumeris.” but it has not as yet been identified.
Cemetery of S. Valentinus.—The old Via Flaminia leaves the city at its north-east corner, and is a direct continuation of the Corso. It is the great road communicating with the north of Italy, as the Via Appia does with South Italy. It passes through the Porta del Popolo, formerly the Gate of S. Valentinus; in old days it was termed the Flaminian Gate. On this Via Flaminia not very far from the city there is the Catacomb of S. Valentinus—the only cemetery on this road.
S. Valentinus is the last of our long catalogue of subterranean cemeteries. Little is known of the confessor and martyr after whom this Catacomb is named. His “Acts,” as we possess them, were only compiled in the sixth century. Valentinus suffered martyrdom circa A.D. 268–70. (Claudius Gothicus was then Emperor.) He is stated to have been a Christian priest and physician.
The martyr’s body was recovered by Sabinilla, a Christian lady, and was buried near the place where he suffered. The desire to be buried near S. Valentinus led to further excavations, but the tufa in this place was too hard and did not lend itself to the formation of galleries. Corridors were excavated above the tomb of the martyr; little, however, of interest has been found as yet. A third gallery was also constructed. It was the second gallery above the grave of the martyr which became the public cemetery, but it has been only very partially examined; much is still blocked up.
Some time after the Peace of the Church, under Pope Julius, A.D. 337–52, a basilica named after S. Valentinus was built a little to the right of the martyr’s crypt. This church was restored, probably rebuilt, by Pope Honorius I, A.D. 625–38. The ruins of this Church of S. Valentinus have been recently brought to light. The Itineraries speak of the body of S. Valentinus as in the restored basilica. These sacred remains were, as in other cases, no doubt translated from their original resting-place into the church above. The bodies of other martyrs who probably suffered in the Diocletian persecution are alluded to in the Pilgrim Guides. In the ruins of the basilica a chapel was identified by an inscription as having been dedicated to certain of the local martyrs, and with these nameless saints S. Zeno is mentioned by name. S. Zeno was evidently once highly venerated. His presence here is accounted for by a notice in one of the Itineraries, which styles him “frater Valentini,”—possibly only signifying “frater in Passione.”
S. Zeno was buried in the well-known Cemetery of Prætextatus on the Appian Way. He is perhaps best known now from the famous Chapel of S. Zeno in the Church of S. Prassedis, the work of Pope Paschal I—usually called the “Orto del Paradiso.” A mosaic in that beautiful chapel pictures the two martyrs S. Valentinus and S. Zeno together.
