To have an idea of the building, as Michael Angelo designed it, it is necessary to go round to the back; and there, with the height and contour of the dome fully seen, all its lines of living force carrying the eye with them up to the elegant stone lantern that crowns the summit, some conception of the hugeness and symmetry of this mountain of art seems to dawn on the mind. But, from the best point of view, it is with the utmost difficulty one can apply any scale of measurement to what, by its vastness and perfection, is bewildering. The interior is most impressive. The arrangements are simple. Passing the vast vestibule, there is the nave of four bays, with two side aisles, and an immense central space, over which hangs the great dome. There are transepts and a choir, each with one bay, and an apse; and there are two side chapels. Since this largest church in the world is divided into so few parts, all of these must be of colossal dimensions. The piers are wonderful masses of masonry, while the spaces spanned by the lofty arches and vaults are prodigious. There is no sense of mystery felt about the interior. The eye at once grasps it as a whole, but hours must be spent before an adequate idea of its gigantic size is at all possible. The beauty of coloring adds wonderfully to the effect. The interior of the dome especially, and the drum on which it rests, are decorated in color throughout, in excellent taste. The designs are simple, the light to show them is ample; and though so rich, there is no impression of excessive decoration. The connection between the dome and the rest of the building seems admirable; and the spectator standing under its soaring vault has an impression of vastness made by no other work of art. In England the new order was introduced with a longer transition period. For a generation or more the style was mixed. In many instances the main lines are Gothic, while the details are partly Gothic and partly modified Renaissance. This is true of such buildings as Knowle, Penshurst, Hardwick, Hatfield, and many others.
