The north transept doorway opens into a groined aisle which occupies the space between the transept and the cloister. This aisle is very dark, and opens at its eastern end into the chapel of Santiago, a fine late building of the age of Ferdinand and Isabella, running north and south, and showing its side elevation in the general view of the east end to the north of the choir. The cloister is so mutilated as to have well-nigh lost all its architectural value. The entrance to the porch in front of the north transept is, however, in its old state; it is a fine doorway, richly and delicately carved with small subjects enclosed in quatrefoils. The original groining shafts, which still remain, show that the whole cloister was built early in the fourteenth century; the traceries, however, have all been destroyed; and the groining, the outer walls, and buttresses altered with vast trouble and cost, into a very poor and weak kind of Renaissance. But if the cloister has lost much of its architectural interest, it is still full of value from another point of view, containing as it does one of the finest series of illustrations of the New Testament that I have ever seen, remaining in each bay of the cloister all the way round. These subjects begin to the east of the doorway to the north transept, and are continued round in regular order till they finish on its western side. I have not been able to learn anything as to the history of these works. If they are Spanish, they prove the existence of a school of painters of rare excellence here, for they are all more or less admirable in their drawing, in the expression of the faces, and in the honesty and simplicity with which they tell their story. The colours, too, where they are still visible, are pure and good, and the whole looked to me like the work of some good Florentine artist of about the middle of the fifteenth century. It would not be a little curious to find the King or Bishop of Leon not only sending to France for his architect, but to Tuscany for his wall-painter, and, if it be the fact, it would show how firm must have been the resolve to make this church as perfect as possible in every respect, and how little dependence was then placed on native talent. The subjects represented are the following, each painting filling the whole of the upper part of the wall in each bay of the cloister:--
