stone, and evidently Moorish in its origin, though, at the same time, the work probably of Christian hands, as in some of them, the figure of the Cross is very beautifully introduced.[271] It is so rare to find any such influence as this exerted, that these traceries have an artificial interest. Yet they are in themselves very charmingly designed, and serve admirably to break the too-powerful rays of the sun. Indeed, nothing in its way can be much prettier than the effect of the shadows of these delicate piercings thrown sharply on the pavement by the brilliant sunlight. The groining is carried by triple engaged shafts, and its thrust resisted by buttresses, with an engaged shaft on their outer face. The groining is simple quadripartite, and the ribs are well moulded; many of the capitals are carved with great vigour, and some of their abaci are covered also with stories admirably rendered. Take, for instance, this story of the Cat and the Rats, which I sketched on one of the abaci of the southern walk of the cloister. It is full of a spirit and humour which are thoroughly foreign to the conventional traditions of our present school of workmen. Give one, now-a-days, such a story to illustrate, and the result would probably be simply absurd, whilst in the hands of this natural Tarragonese artist the whole thing is instinct with life and humour, to as great an extent now as it was when his brother workmen first gathered round him and laughed their approval of the speedy retribution which met the silly rats when they forgot to tie the limbs of their enemy. I ought to have sketched the capitals which were under this abacus, for they were sculptured with cocks fighting, with their wings and heads so ingeniously arranged as to conform to the ordinary outlines of the early thirteenth-century foliage capital. It is rarely that so much fine and original sculpture of various kinds is to be found in one such church as this; and I recommend those who follow my footsteps here to go prepared to devote some little time to the accurate delineation and careful study of it.
