Opening from the left aisle is the chapel of the Caetani family, with tombs of the seventeenth century. Over the altar is a bas-relief of the Adoration of the Magi, by Paolo Olivieri. On each side are fine columns of Lunachella marble. Over the entrance from the nave are ancient mosaics,—of the Evangelists and of Sta. Pudenziana collecting the blood of the martyrs. Beneath, is a gloomy and neglected vault, in which all the sarcophagi and coffins of the dead Caetani are shown by torchlight.
In the tribune are magnificent mosaics, ascribed by some to the eighth, by others to the fourth century, and considered by De Rossi,[238] as the best of all ancient Christian mosaics.
"In conception and treatment this work is indeed classic: seated on a rich throne in the centre, is the Saviour with one arm extended, and in the other hand holding a book open at the words, Conservator Ecclesiæ Pudentianæ; laterally stand SS. Praxedis and Pudentiana with leafy crowns in their hands; and at a lower level, but more in front, SS. Peter and Paul with eight other male figures, all in the amply-flowing costume of ancient Romans; while in the background are seen, beyond a portico with arcades, various stately buildings, one a rotunda, another a parallelogram with a gable-headed front, recognizable as a baptistery and basilica, here, we may believe, in authentic copy from the earliest types of the period of the first Christian emperors. Above the group, and hovering in the air, a large cross, studded with gems, surmounts the head of our Saviour, between the four symbols of the Evangelists, of which one has been entirely, and another in the greater part, sacrificed to some wretched accessories in woodwork actually allowed to conceal portions of this most interesting mosaic! As to expression, a severe solemnity is that prevailing, especially in the principal head, which alone is crowned with the nimbus—one among other proofs, if but negative, of its high antiquity."—Heman's Ancient Christian Art.
Besides Sta. Pudenziana and St. Pudens,—St. Novatus and St. Siricius are said to be buried here. Those who visit this sanctuary every day obtain an indulgence of 3000 years, with remission of a third part of their sins! Excavations made by Mr. J. H. Parker, in 1865, have laid bare some interesting constructions beneath the church,—supposed to be those of the house of Pudens—a part of the public baths of Novatus, the son of Pudens, which were in use for some centuries after his time, and a chamber in which is supposed to have been the oratory dedicated by Pius I. in a.d. 145.
"Eubulus greeteth thee, and Pudens, and Linus, and Claudia, and all the brethren."—2 Timothy iv. 21.
The following account of the family of Pudens is received as the legacy of Pastor to the Christian Church.
"Pudens went to his Saviour, leaving his daughters strengthened with chastity, and learned in all the divine law. These sold their goods, and distributed the produce to the poor, and persevered strictly in the love of Christ, guarding intact the flower of their virginity, and only seeking for glory in vigils, fastings, and prayer. They desired to have a baptistery in their house, to which the blessed Pius not only consented, but with his own hand drew the plan of the fountain. Then calling in their slaves, both from town and country, the two virgins gave liberty to those who were Christians, and urged belief in the faith upon those who had not yet received it. By the advice of the blessed Pius, the affranchisement was declared, with all the ancient usages, in the oratory founded by Pudens; then, at the festival of Easter, ninety-six neophytes were baptized; so that thenceforth assemblies were constantly held in the said oratory, which night and day resounded with hymns of praise. Many pagans gladly came thither to find the faith and receive baptism.
"Meanwhile the Emperor Antonine, being informed of what was taking place, issued an edict commanding all Christians to dwell apart in their own houses, without mixing with the rest of the people, and that they should neither go to the public shops, nor to the baths. Praxedis and Pudentiana then assembled those whom they had led to the faith, and housed them. They nourished them for many days, watching and praying. The blessed bishop Pius himself frequently visited us with joy, and offered the sacrifice for us to the Saviour.
"Then Pudentiana went to God. Her sister and I wrapped her in perfumes and kept her concealed in the oratory. Then, at the end of twenty-eight days, we carried her to the cemetery of Priscilla, and laid her near her father Pudens.
"Eleven months after, Novatus died in his turn. He bequeathed his goods to Praxedis, and she then begged of St. Pius to erect a titular (a church) in the baths of Novatus, which were no longer used, and where there was a large and spacious hall. The bishop made the dedication in the name of the blessed virgin Praxedis. In the same place he consecrated a baptistery.
