“ It was not until the reign of Constantine that Christian edifices began to assume the attributes of size, magnificence, and majestic boldness of outline. It was then that the emperor erected basilicas in the interior of his Lateran and Vatican palaces for the first time, and consecrated to the worship of the true God those immense edifices in which art was the humble handmaid of religion and bathed itself in the ineffable splendours of the faith. ”
