carrying round of string courses, and other such continuous work; not but that they may stop sometimes, on the point of going into some palpably impenetrable recess, but then let them stop boldly and markedly, on some distinct terminal ornament, and never be supposed to exist where they do not. The arches of the towers which flank the transepts of Rouen Cathedral have rosette ornaments on their spandrils, on the three visible sides; none on the side towards the roof. The right of this is rather a nice point for question.
XII. Visibility, however, we must remember, depends, not only on situation, but on distance; and there is no way in which work is more painfully and unwisely lost than in its over delicacy on parts distant from the eye. Here, again, the principle of honesty must govern our treatment: we must not work any kind of ornament which is, perhaps, to cover the whole building (or at least to occur on all parts of it) delicately where it is near the eye, and rudely where it is removed from it. That is trickery and dishonesty. Consider, first, what kinds of ornaments will tell in the distance and what near, and so distribute them, keeping such as by their nature are delicate, down near the eye, and throwing the bold and rough kinds of work to the top; and if there be any kind which is to be both near and far off, take care that it be as boldly and rudely wrought where it is well seen as where it is distant, so that the spectator may know exactly what it is, and what it is worth. Thus chequered patterns, and in general such ornaments as common workmen can execute, may extend over the whole building; but bas-reliefs, and fine niches and capitals, should be kept down; and the common sense of this will always give a building dignity, even though there be some abruptness or awkwardness in the resulting arrangements. Thus at San Zeno at Verona, the bas-reliefs, full of incident and interest, are confined to a parallelogram of the front, reaching
