The internal arrangements here do not present much subject for notice. The Coro is in the nave, and in the screen on its western side the entrance-doorway still remains. It is of marble, of two well-moulded orders, and the outer order of the arch has voussoirs of grey and white marble counterchanged. The steps are of dark marble, with three shields in low relief on the riser of each, and the bearings which occur here are seen also in the keystone of the tower vaulting--both being works of the fourteenth century. The choir stalls and the panelling behind them are of the very richest and most delicate fifteenth-century work; and the great desk for books, in the centre of the Coro, is of the same age.[274] The stall-ends are covered with delicate tracery, put on in a separate piece against the end, and not carved out of the solid. The divisions between the panelling at the back of the stalls are wrought with foliage and animals of really marvellous execution, and a band of inlaid work with coats-of-arms goes all round just above the stalls. There is a throne on the right hand of the entrance to the choir, and another at the east end of the south side; but both of these are of Renaissance character. Many of the choir books are mediæval, with large knops at their angles, and a piece of fringed leather under each knop. At the east end of the Coro, and in a line with the west wall of the transepts, is the iron Reja, and on each side of it a pulpit facing east. These have all the appearance of having been rebuilt. They have the same armorial bearings as the doorway to the Coro; and as the screen in which the latter is now built is not old, it is probable that they all form part of the same old choir screen, and that the two pulpits were the ambons. I saw nothing to prove decidedly whether the Coro was in its original place, or whether it has been moved down into the nave as at Burgos. The great organ is on the north side of the Coro; it is not very old, but its pipes are picturesquely arranged, and it has enormous painted wings or shutters.
