XVI. It might have been thought that, by this plan, enough variety had been secured, but the builder was not satisfied even thus: for--and this is the point bearing on the present part of our subject--always calling the central arch _a_, and the lateral ones _b_ and _c_ in succession, the northern _b_ and _c_ are considerably wider than the southern _b_ and _c_, but the southern _d_ is as much wider than the northern _d_, and lower beneath its cornice besides; and, more than this, I hardly believe that one of the effectively symmetrical members of the façade is actually symmetrical with any other. I regret that I cannot state the actual measures. I gave up the taking them upon the spot, owing to their excessive complexity, and the embarrassment caused by the yielding and subsidence of the arches. Do not let it be supposed that I imagine the Byzantine workmen to have had these various principles in their minds as they built. I believe they built altogether from feeling, and that it was because they did so, that there is this marvellous life, changefulness, and subtlety running through their every arrangement; and that we reason upon the lovely building as we should upon some fair growth of the trees of the earth, that know not their own beauty. XVII. Perhaps, however, a stranger instance than any I have yet given, of the daring variation of pretended symmetry, is found in the front of the Cathedral of Bayeux. It consists of five arches with steep pediments, the outermost filled, the three central with doors; and they appear, at first, to diminish in regular proportion from the principal one in the centre. The two lateral doors are very curiously managed. The tympana of their arches are filled with bas-reliefs, in four tiers; in the lowest tier there is in each a little temple or gate containing the principal figure (in that on the right, it is the gate of Hades with Lucifer). This little temple is carried, like a capital, by an isolated shaft which divides the whole arch at about 2/3 of its breadth, the larger portion outmost; and in that larger portion is the inner entrance door. This exact correspondence, in the treatment of both gates, might lead us to expect a correspondence in dimension. Not at all. The small inner northern entrance measures, in English feet and inches, 4 ft. 7 in. from jamb to jamb, and the southern five feet exactly. Five inches in five feet is a considerable variation. The outer northern porch measures, from face shaft to face shaft, 13 ft. 11 in., and the southern, 14 ft. 6 in.; giving a difference of 7 in. on 14-1/2 ft. There are also variations in the pediment decorations not less extraordinary.
