BUT the most harmful and destructive force which operated against these fine arts was the fervent zeal of the new Christian religion, which, after long and sanguinary strife, had at length vanquished and abolished the old faith of the heathen, by means of a number of miracles and by the sincerity of its acts. Every effort was put forth to remove and utterly extirpate the smallest things from which errors might arise, and thus not only were the marvellous statues, sculptures, paintings, mosaics and ornaments of the false pagan gods destroyed and thrown down, but also the memorials and honours of countless excellent persons, to whose distinguished merits statues and other memorials had been set up in public by a most virtuous antiquity. Besides all this, in order to build churches for the use of the Christians, not only were the most honoured temples of the idols destroyed, but in order to ennoble and decorate S. Pietro’ with more ornaments than it then possessed, they took away the stone columns from the mold of Hadrian, now the castle of Sant’Angelo, as well as many other things which we now see in ruins.
