The Retablo is no less worthy of notice. Its colour as well as its sculpture is of the richest kind. Below, on either side of the tabernacle (which has been modernized), are St. John Baptist and S. Mary Magdalene, and subjects on either side of them; on the left the Annunciation, and S. Mary Magdalene anointing our Lord’s feet, and on the right the Adoration of the Magi, and the Betrayal of our Lord; whilst beyond, Alfonso and Isabel kneel at faldstools, with their coats-of-arms above them. Above the Tabernacle is the Assumption of the Blessed Virgin, and above this a grand circle entirely formed of clustered angels, in the centre of which is a great crucifix surmounted by the Pelican vulning her breast. Within this circle are four subjects from the Passion, and a King and a Pope on either side holding the arms of the Cross, which is completely detached from the background. On either side are S. John and S. Mary; and beside all these, a crowd of subjects and figures, pinnacles and canopies, which it is impossible to set down at length. The whole of this work was done by the same Gil de Siloe, assisted by Diego de la Cruz, at a cost of 1,015,613 maravedis, and was executed between A.D. 1496 and 1499. Behind the Retablo some of the old pavement remains, of encaustic tiles in blue, white, and red. The works at this church seem to have made but slow progress owing to the troubled state of the kingdom after the death of Juan II. His son gave something towards the works in A.D. 1454, but nothing more until A.D. 1465. In A.D. 1474 he died, and was succeeded by Isabel the Catholic, who, in A.D. 1476, confirmed the grants to the monastery, and completed the church in A.D. 1488; but it was not, as we have seen, until the end of the century that the whole work was really finished. Juan de Colonia made the plan for the building in A.D. 1454, for which he received 3350 maravedis: he directed its construction for twelve years, and after his death, in A.D. 1466, Garci Fernandez de Matienzo continued it till he died of the plague in the year 1488, when Simon, son of Juan de Colonia, completed it.[43]
