[Illustration: PLATE VII.--(Page 93--Vol. V.) PIERCED ORNAMENTS FROM LISIEUX, BAYEUX, VERONA, AND PADUA.] XX. The method of decoration by shadow was, as far as we have hitherto traced it, common to the northern and southern Gothic. But in the carrying out of the system they instantly diverged. Having marble at his command, and classical decoration in his sight, the southern architect was able to carve the intermediate spaces with exquisite leafage, or to vary his wall surface with inlaid stones. The northern architect neither knew the ancient work, nor possessed the delicate material; and he had no resource but to cover his walls with holes, cut into foiled shapes like those of the windows. This he did, often with great clumsiness, but always with a vigorous sense of composition, and always, observe, depending on the _shadows_ for effect. Where the wall was thick and could not be cut through, and the foilings were large, those shadows did not fill the entire space; but the form was, nevertheless, drawn on the eye by means of them, and when it was possible, they were cut clear through, as in raised screens of pediment, like those on the west front of Bayeux; cut so deep in every case, as to secure, in all but a direct low front light, great breadth of shadow. The spandril, given at the top of Plate VII., is from the southwestern entrance of the Cathedral of Lisieux; one of the most quaint and interesting doors in Normandy, probably soon to be lost forever, by the continuance of the masonic operations which have already destroyed the northern tower. Its work is altogether rude, but full of spirit; the opposite spandrils have different, though balanced, ornaments very inaccurately adjusted, each rosette or star (as the five-rayed figure, now quite defaced, in the upper portion appears to have been) cut on its own block of stone and fitted in with small nicety, especially illustrating the point I have above insisted upon--the architect's utter neglect of the forms of intermediate stone, at this early period. The arcade, of which a single arch and shaft are given on the left, forms the flank of the door; three outer shafts bearing three orders within the spandril which I have drawn, and each of these shafts carried over an inner arcade, decorated above with quatre-foils, cut concave and filled with leaves, the whole disposition exquisitely picturesque and full of strange play of light and shade.
