). In the procession which took place on S. Mark's day, from the church of S. Lorenzo in Lucina to S. Peter's, through the Via Flaminia and across the Ponte Milvio, the first halt was made at S. Valentine's,[93] the second at the chapel of the Holy Cross. The "Liber Pontificalis," in the Life of Leo III. (795-816), speaks of this strange ceremony. It was called the "great litany," and occurred on the twenty-third of April, the day on which the Romans used to celebrate the Robigalia. The Christian litany and the pagan ceremony had the same purpose, that of securing the blessing of Heaven upon the fields, and averting from them the pernicious effects of late spring frosts. The rites were nearly the same, the principal one being a procession which left Rome by the Porta Flaminia, and passed across the Ponte Milvio to a suburban sanctuary. The end of the pagan pilgrimage was a temple of the god Robigus or the goddess Robigo, situated at the fifth milestone of the Via Claudia; that of the Christian the monumental cross near the same road, and ultimately the basilica of S. Peter's. In course of time the oratory and cross lost their genuine meaning; they were thought to mark the spot on which the miraculous vision had appeared to Constantine on the eve of battle. This was not the case, however, because Eusebius, to whom the emperor himself described the event, says that the luminous sign appeared to him before the commencement of military operations, which means before he crossed the Alps and took possession of Susa, Turin, and Vercelli. But, if the heavenly apparition of the "sign of Christ" on Monte Mario is historically without foundation, the existence of the oratory is not. Towards the end of the twelfth century it was in a ruinous state, and converted probably into a stable or a hay-loft. The last archæologist who mentions it is Seroux d'Agincourt. He describes the ruins "on the slopes of the hill of the Villa Madama," and gives a sketch of the paintings which appeared here and there on the broken walls. Armellini and myself have explored the beautiful woods of the Villa Madama in all directions without finding a trace of the building. It was probably destroyed in the disturbances of 1849.
The noble house of the Millini, to whom the Mons Vaticanus owes its present name of Monte Mario (from Mario Millini, son of Pietro and grandson of Saba), while building their villa on the highest ridge, in 1470, raised a chapel in place of the one which had been profaned, and called it Santa Croce a Monte Mario. It was held in great veneration by the Romans, who made pilgrimages to it in times of public calamities, such as the famous plague (contagio-moria) of Alexander VII. I well remember this interesting little church, before its disappearance in 1880. Its pavement, according to the practice of the time, was inlaid with inscriptions from the catacombs, whole or in fragments, twenty-four of which are now preserved in the Lipsanotheca (Palazzo del Vicario, Piazza di S. Agostino). They contain a curious list of names, like Putiolanus (so called from his birth-place, Pozzuoli) or Stercoria, a name which seems to have been taken up by devout people, as a sign of humility. Another inscription over the door of the sacristy spoke of a restoration of the building in 1696; a third, composed by Pietro and Mario Mellini in 1470, sang the praises of the cross. The most important record, however, was engraved on a slab of marble at the left of the entrance:—
"This oratory was first built in the year of the jubilee, MCCCL, by Pontius, bishop of Orvieto and vicar of the city of Rome."
The inscription, besides proving that the removal of the oratory from its original site to the summit of the mountain had been accomplished before the age of the Millini, is the only historical record of the jubilee of 1350, which attracted to Rome enormous multitudes, so that pilgrims' camps had to be provided both inside and outside the walls. Petrarca and king Louis of Hungary (then on his way back from Apulia) were among the visitors. Bishop Pontius of Orvieto, Ponzio Perotti, is also an historical man. He was intrusted with the government of the city in consequence of the attempted assassination of his predecessor, cardinal Annibaldo, by a partisan of Cola di Rienzo.
This chapel, to which so many interesting souvenirs were attached, which owed its origin to one of the greatest battles in history, which commanded one of the finest panoramas in the world, is no more. It was sacrificed in 1880 to the necessity of raising a fortress on the hill. No sign is left to mark its place.
