The frescoes by Giotto, sadly repainted, in the fourth chapel on the left, must be noted. They represent the four Evangelists with their symbols over them, and the four Latin fathers of the Church, S. Jerome, S. Ambrose, S. Austin, and S. Gregory. Certain fragments of a thirteenth-century mosaic pavement are to be seen in the chapel of S. Bartholomew, which is itself perhaps the oldest part of the church.
We turn now to the church of S. Giovanni Battista which was founded by a certain Baduarius, according to Agnellus, and consecrated by S. Peter Chrysologus. It is possible that Baduarius was the mere builder, and that he built by order of Galla Placidia. Nothing, however, is left of the old church, which was entirely rebuilt in 1683, except the apse as it is seen from the outside, the round campanile in its first story and the beautiful columns sixteen in number, four of bigio antico, two of pavonazzetto, one of cipollino, and the rest of greco venato, according to Dr. Ricci.

There remains to be considered what is, when all is said, I suppose the noblest monument of the fifth century left to us in Italy or in Europe—the Mausoleum of Galla Placidia.
Agnellus tells us that the Augusta built close to her palace a great church in the shape of a Latin cross. This she dedicated in honour of the Holy Cross which it will be remembered her predecessor S. Helena had discovered in Jerusalem. Of this church, though it has long since disappeared—the "western" part of it having been destroyed in 1602 and what remained restored out of all recognition in 1716—we know a good deal. According to Agnellus it was covered with most precious stones (? marbles) and apparently with mosaics and was full of splendid ornaments. It had, too, a great narthex, and at the end of this Galla Placidia presently built a cruciform oratory for her own mausoleum, where she was to lie between her brother Honorius and her son Valentinian.

The Mausoleum of Galla Placidia is the oldest complete building left to us in Ravenna, for it dates from well within the first half of the fifth century, whereas the baptistery, altered and transformed as it was by S. Neon, is as we see it a work of the first years of the second half of that century. Simple as it is, without, a cruciform building of plain brick, within it is so sumptuously and splendidly adorned that not an inch anywhere remains that is not encrusted with mosaic or precious marbles. These mosaics were, before their radical "restoration," perhaps finer and more classical than those of the baptistery. It might seem, indeed, that they were perhaps the finest and subtlest work done in the Roman realistic tradition, nor was there perhaps anywhere to be found so noble a representation of the Good Shepherd as that which adorned this great monument. It is, however, impossible to speak with any confidence of what we see there now, for all has been restored again and again, and is now little better than a rifacimento of our own time, a copy, faithful perhaps, but still a copy, of the work of the fifth century.
Nevertheless, the impression of the whole is very splendid and solemn. The roofs and dome are covered with mosaics of a wonderful and indescribable night blue, powdered with stars. In the cupola is a cross and at the four angles are set the symbols of the four Evangelists, glorious heraldic figures.
Above the door we see Christ the Good Shepherd, youthful, classic in form and repose, very noble and Roman, seated on a rock in a broken hilly landscape, a cross in His left hand, caressing His sheep with His right. This figure even after "restoration" gives us more than a glimpse of what it once was. Nowhere had Christian art produced so majestic a representation of its Lord; nor had the subject of the Good Shepherd been anywhere more splendidly treated than here.
Over the great sarcophagus, opposite the entrance, we see a very different scene. Here is no longer a youthful Christ, with the hair and the noble aspect of Apollo, but a bearded and majestic figure in the fullness of manhood, His eyes full of anger, His draperies flying about Him, moving swiftly, the cross on His shoulders, in His left hand an heretical, probably Arian, book which he is about to cast into the furnace in the midst. Upon the extreme left is a case or cupboard in which we see the books of the four Gospels. In the other lunettes we see very gorgeous decorative work of arabesques and stags at a fountain and two doves drinking from a vase. Above in the spandrils of the arches are figures of apostles or saints. Nothing in the world is more solemnly gorgeous in effect than this beautiful rich interior. The pavement is composed of fragments of the same precious marbles as those which line the lower parts of the walls.
