These facts are of great interest, proving as they do that the stalls stood from the year 1410 to 1518 in their proper place in the choir, and were then moved to their present position in the nave precisely in the same way that we have already seen the old arrangement changed at Burgos at about the same period. This peculiar Spanish arrangement of the Coro in the nave, and separated from the altar, we may now, I think, assume was not known or thought of until this comparatively late date in this part of Spain, though now it is universal throughout the country. The design of the stalls is somewhat like that of late Flemish work, but peculiar in many respects: the forward slope of the stall elbows, the rich traceries behind the lower stalls--very varied in their design--and the upper stalls, are all worthy of notice. I did not observe any distinction in the style of the work answering to the dates at which Maestro Centellas and Pedro de Guadalupe were employed, and I think, therefore, that the latter must have copied rather closely the work of the former. Probably, however the Prie-Dieu desk in front of the bishop’s stall is of the later date, as also the desks which have been widened in front of the upper row of stalls; and possibly Pedro de Guadalupe executed the twenty stalls on each side of the choir forming the easternmost block. [Illustration: Prie-Dieu.] The eastern part of the church has been worse treated even than the nave, all the old arrangements having been ruthlessly altered. The apse, shut in by screens, covered with a low groined gallery, and used as a mere chapel,[67] is dark, dismal, and undignified. The bay west of the apse is open from north to south, but walled in on the west with the wall behind the high altar. West of this are two bays walled in at the sides, and then we come to the transept, which is open, save the rails marking the passage from the Coro to the choir. The whole arrangement is so confused, unintelligible, and contrary to the obvious intentions of the first designers of the fabric, that it hardly needed documentary evidence to prove that it had no kind of ancient authority. There is no lantern or Cimborio at the crossing. The metal screens[68] across the choir are of no special interest, but those round the apse and opening into one or two of the chapels of the chevet are better, and well illustrate the designs of most of the fifteenth-century iron screens in Spain. They are met with in all directions, for there was no country in the middle ages which made so free a use of iron. They have most of the faults of German ironwork of the same age, the smiths having apparently forgotten the right use of their hammers, and, like Birmingham smiths of the present day, having tried to do what was necessary with thin plates of iron twisted about fantastically here and there, but very much more easily wrought, and proportionably less effective, than the work of the English smiths of a couple of hundred years earlier.
