The chancel is raised and surrounded by an inlaid marble screen. Instead of ambones there are two plain marble reading-desks for the epistle and gospel. The altar is inlaid, and has "transennæ," or a marble grating, through which the tomb of the saints Nereus and Achilles may be seen, and through which the faithful might pass their handkerchiefs to touch it. Behind, in the semicircular choir, is an ancient episcopal throne, supported by lions, and ending in a gothic gable. Upon it part of the twenty-eighth homily of St. Gregory was engraved by Baronius, under the impression that it was delivered thence,—though it was really first read in the catacomb, whence the bodies of the saints were not yet removed. All these decorations are of the restoration under Leo III., in the eighth century. Of the same period are the mosaics on the arch of the tribune (partly painted over in later times), representing, in the centre, the Transfiguration (the earliest instance of the subject being treated in art), with the Annunciation on one side, and the Madonna and Child attended by angels on the other.
It is worth while remarking that when the relics of Flavia Domitilla (who was niece of Vespasian) and of Nereus and Achilles were brought hither from the catacomb on the Via Ardeatina, which bears the name of the latter, they were first escorted in triumph to the Capitol, and made to pass under the imperial arches which bore as inscriptions: "The senate and the Roman people to Sta. Flavia Domitilla, for having brought more honour to Rome by her death than her illustrious relations by their works." ... "To Sta. Flavia Domitilla, and to the Saints Nereus and Achilles, the excellent citizens who gained peace for the Christian republic at the price of their blood."
Opposite, on the left, is a courtyard leading to the Church of S. Sisto, with its celebrated convent, long deserted on account of malaria.
It was here that St. Dominic first resided in Rome, and collected one hundred monks under his rule, before he was removed to Sta. Sabina by Honorius III. After he went to the Aventine, it was decided to utilize this convent by collecting here the various Dominican nuns, who had been living hitherto under very lax discipline, and allowed to leave their convents, and reside in their own families. The nuns of Sta. Maria in Trastevere resisted the order, and only consented to remove on condition of bringing with them a Madonna picture attributed to St. Luke, hoping that the Trasteverini would refuse to part with their most cherished treasure. St. Dominic obviated the difficulty by going to fetch the picture himself at night, attended by two cardinals, and a bare-footed, torch-bearing multitude.
"On Ash-Wednesday, 1218, the abbess and some of her nuns went to take possession of their new monastery, and being in the chapter-house with St. Dominic and Cardinal Stefano di Fossa Nuova, suddenly there came in one tearing his hair, and making great outcries, for the young Lord Napoleon Orsini, nephew of the cardinal, had been thrown from his horse, and killed on the spot. The cardinal fell speechless into the arms of Dominic, and the women and others who were present were filled with grief and horror. They brought the body of the youth into the chapter-house, and laid it before the altar; and Dominic, having prayed, turned to it, saying, 'O adolescens Napoleo, in nomine Domini nostri Jesu Christi tibi dico surge,' and thereupon he arose sound and whole, to the unspeakable wonder of all present."—Jameson's Monastic Orders.
After being convinced by this miracle of the divine mission of St. Dominic, forty nuns settled at S. Sisto, promising never more to cross its threshold.[194]
There is very little remaining of the ancient S. Sisto, except the campanile, which is of 1500. But the vaulted Chapter-House, now dedicated to St. Dominic, is well worth visiting. It has recently been covered with frescoes by the Padre Besson,—himself a Dominican monk,—who received his commission from Father Mullooly, Prior of S. Clemente, the Irish Dominican convent, to which S. Sisto is now annexed. The three principal frescoes represent three miracles of St. Dominic—in each case of raising from the dead. One represents the resuscitation of a mason of the new monastery, who had fallen from a scaffold; another, that of a child in a wild and beautiful Italian landscape; the third, the restoration of Napoleone Orsini on this spot,—the mesmeric upspringing of the lifeless youth being most powerfully represented. The whole chapel is highly picturesque, and effective in colour. Of two inscriptions, one commemorates the raising of Orsini; the other, a prophecy of St. Dominic, as to the evil end of two monks who deserted their convent.
Just beyond S. Sisto, where the Via della Ferratella branches off on the left to the Lateran, stands a small ædiculum, or Shrine of the Lares, with brick niches for statues.
Further, on the right, standing back from a kind of piazza, adorned with an ancient granite column, is the Church of S. Cesareo, which already existed in the time of St. Gregory the Great, but was modernized under Clement VII. (1523—34). Its interior retains many of its ancient features. The pulpit is one of the most exquisite specimens of church decoration in Rome, and is covered with the most delicate sculpture, interspersed with mosaic; the emblems of the Evangelists are introduced in the carving of the panels. The high altar is richly encrusted with mosaics, probably by the Cosmati family; tiny owls form part of the decorations of the capitals of its pillars. Beneath is a "confession," where two angels are drawing curtains over the tomb of the saint. The chancel has an inlaid marble screen. In the tribune is an ancient episcopal throne, once richly ornamented with mosaics.
In this church St. Sergius was elected to the papal throne, in 687; and here, also, an Abbot of SS. Vincenzo ed Anastasio was elected in 1145, as Eugenius III., and was immediately afterwards forced by the opposing senate to fly to Montecelli, and then to the Abbey of Farfa, where his consecration took place.
