The outer walls of the choir are also completely covered with sculpture. It is thoroughly Gothic in character, crude, and fumbling for expression, consisting of arcades with niches above containing alto-relievo illustrations of Old Testament scenes and characters. You recognize the Garden of Eden, Abraham with agonized face, Isaac, Jacob, passages from Exodus, and other familiar scenes. Many of the panels depict further the small, everyday occurrences and incidents so loved by mediæval artists, and so full of earnest, religious feeling. Crowning it all, amid the pinnacles, are a whole flock of angels, quite prepared for Ascension Day. It is all very similar to the early fourteenth-century work in French cathedrals. The bay in front of the high altar, forming with it the Capilla Mayor, and the choir are closed from the transept by a huge reja as fine as the one facing it, and the work of the Spaniard Francesco Villalpando (1548).[14] The Capilla Mayor originally consisted of the one bay to the east of the transept, the adjacent terminating portion of the nave being the chapel containing the tombs of the kings. The great Cardinal Ximenez received Isabella's permission to remove the dividing wall in case he could accomplish the task without disturbing any of the monarchs' coffins. The walls all round, both internally and externally, are completely covered with sculpture. Many of the figures are faithful portraits; many of the groups tell an interesting story. On the Gospel side there are two carvings, one over the other, the upper representing Don Alfonso VIII, and the lower, the shepherd who guided the monarch and his army to the renowned plains of Las Navas de Tolosa, where the battle was fought which proved so glorious to Christian arms. One likewise sees the statue of the Moor, Alfaqui Abu Walid, who threw himself in the path of King Alfonso and prevailed upon him to forgive Queen Constance and Bishop Bernard for the expulsion of the Moors from their mosque, contrary to the king's solemn oath. All around us lie the early rulers of the House of Castile, Alfonso VII, Sancho the Deserted, and Sancho the Brave, the Prince Don Pedro de Aguilar, son of Alfonso XI, and the great Cardinal Mendoza. Below in the vault lie, by the sides of their consorts, Henry II, John I, and Henry III.
