John Lateran, built by the same emperor, may serve as evidence of the same fact, namely, that sculpture had already greatly declined in his time, because the figures of the Saviour and of the twelve apostles in silver, which he caused to be made, were very base works, executed without art and with very little design. In addition to this, it is only necessary to examine the medals of this emperor, and other statues made by the sculptors of his day, which are now at the Capitol, to clearly perceive how far removed they are from the perfection of the medals and statues of the other emperors, all of which things prove that sculpture had greatly declined long before the coming of the Goths to Italy. Architecture, as I have said, maintained its excellence at a higher though not at the highest level. Nor is this a matter for surprise, since large buildings were almost entirely constructed of spoils, so that it was easy for the architects to imitate the old in making the new, since they had the former continually before their eyes. This was an easier task for them than far the sculptors, as the art of imitating the good figures of the ancients had declined. A good illustration of the truth of this statement is afforded by the church of the chief of the apostles in the Vatican, which is rich in columns, bases, capitals, architraves, cornices, doors and other incrustations and ornaments which were all taken from various places and buildings, erected before that time in very magnificent style. The same remarks apply to S. Croce at Jerusalem, which Constantine erected at the entreaty of his mother, Helena; of S. Lorenzo outside the wall, and of S. Agnesa, built by the same emperor at the request of his daughter Constance. Who also is not aware that the font which served for the baptism of the latter and of one of her sisters, was ornamented with fragments of great antiquity? as were the porphyry pillar carved with beautiful figures and some marble candelabra exquisitely carved with leaves, and some children in bas-relief of extraordinary beauty? In short, by these and many other signs, it is clear that sculpture was in decadence in the time of Constantine, and with it the other superior arts. If anything was required to complete their ruin it was supplied by the departure of Constantine from Rome when he transferred the seat of government to Byzantium, as he took with him to Greece not only all the best sculptors and other artists of the age, such as they were, but also a quantity of statues and other beautiful works of sculpture.
