In one respect, however, the design of this church is very important. The Spanish architects seldom troubled themselves to suit their buildings in any respect to the climate; and this, no doubt, because in very many cases they were merely imitating the works of another country, in which no precautions against heat were necessary. Here we have a church expressly designed, and with great judgment, for the requirements of the climate. The windows are very high up, and very small for the size of the building, so that no sunlight could ever make its way to any unpleasant extent into it. There are galleries in front of all the windows, both in the nave and aisles, but they are of thoroughly Renaissance character. The section of the church gives a main clerestory to the nave, and a second clerestory on one side of each aisle over the arches opening into the side chapels. The upper clerestory has two windows of two lights, and a circular window above them in each bay, and the lower clerestory traceried windows generally, I think, of three lights. The traceries are very weak and ill proportioned; but I noticed in places what seemed to be a recurrence to earlier traditions in the groupings of small windows, with several circles pierced in the wall above them. It was, however, just like the imitation of old works we so often see from incompetent hands at the present day. You see whence the idea has been taken, though it is so travestied as to be not even tolerable where the original was probably perfect! The planning of the church is certainly infelicitous. The square east end is bald to a degree externally, and finished as it is inside with chapels corresponding with those of the aisles, wants relief and life. If the square east end is adopted in a great church, no doubt the prolonged Lady Chapels of our own churches are infinitely to be preferred to such a plan as this, which fails to give the great east windows of which we boast, and loses all the effects of light and shade in which the apsidal chevets of the Continent are so rich.
