Even as the first of the poets, by common consent, is said to be Homer, not because there were none before him, for there were, although not so excellent, which is seen clearly from his own works, but because of these early poets, whatever manner of men they were, all knowledge had been lost quite 2,000 years before. However, leaving behind us this part, as too uncertain by reason of its antiquity, let us come to the clearer matters of their perfection, ruin, and restoration, or rather resurrection, whereof we will be able to discourse on much better grounds. I say, then, it being true indeed, that they began late in Rome, if the first figure was, as is said, the image of Ceres made of metal from the treasure of Spurius Cassius, who, for conspiring to make himself King, was put to death by his own father without any scruple; and that although the arts of sculpture and of painting continued up to the end of the twelve Caesars, they did not, however, continue in that perfection and excellence which they had enjoyed before, for it may be seen from the edifices that the Emperors built in succession one after the other that these arts, decaying from one day to another, were coming little by little to lose their whole perfection of design. And to this clear testimony is borne by the works of sculpture and of architecture that were wrought in the time of Constantine in Rome, and in particular the triumphal arch raised for him by the Roman people near the Colosseum, wherein it is seen that in default of good masters they not only made use of marble groups made at the time of Trajan, but also of the spoils brought from various places to Rome. And whosoever knows that the votive offerings in the medallions, that is, the sculptures in half-relief, and likewise the prisoners, and the large groups, and the columns, and the mouldings, and the other ornaments, whether made before or from spoils, are excellently wrought, knows also that the works which were made to fill up by the sculptors of that time are of the rudest, as also are certain small groups with little figures in marble below the medallions, and the lowest base wherein there are certain victories, and certain rivers between the arches at the sides, which are very rude and so made that it can be believed most surely that by that time the art of sculpture had begun to lose something of the good. And there had not yet come the Goths and the other barbarous and outlandish peoples who destroyed, together with Italy, all the finer arts. It is true, indeed, that in the said times architecture had suffered less harm than the other arts of design had suffered, for in the bath that Constantine erected on the Lateran, in the entrance of the principal porch it may be seen, to say nothing of the porphyry columns, the capitals wrought in marble, and the double bases taken from some other place and very well carved, that the whole composition of the building is very well
