The outer walls of the chevet, as we have seen, are the most ancient part of the fabric, but the seven chapels formed within the thickness of the wall are of later date. The extraordinary beauty of this part of the church is due to the division of the ambulatory into two by a series of tall, slender columns carrying some excellent groining. The outer or recessed aisle is narrower than the inner, an inequality corrected very skilfully at the opening into the south transept by an imperceptible deviation in the line of columns. Very little light penetrates through the narrow slits in the chapel walls into this sombre, beautiful arcade.

Behind the reredos of the High Altar sleeps the learned bishop, Don Alonso Fernández de Madrigal, surnamed el Tostado and el Abulense, who died in 1455. The prelate, who was one of the most prolific writers that ever lived, is shown in alabaster writing at a desk. The framework of the tomb is adorned with reliefs of the Adoration of the Magi and Shepherds, of the Divine and Cardinal Virtues, and of the Eternal Father. This noble work has been variously ascribed to Berruguete and to Domenico Fancelli, whose more famous performance we shall see in the church of Santo Tomás.

In the chapel of Santa Ana is buried Don Sancho Davila, Bishop of Plasencia, who died in 1625. Most of the tombs in the chapels of the chevet belong, however, to the thirteenth century, though the dates on most of them are merely conjectural, and were inscribed in the sixteenth century by a prebendary of the cathedral.

The High Altar is backed by an elaborate retablo of the age of the Catholic Kings. It is divided into three stages, and was painted by Pedro Berruguete (father of the more famous Alonso), Santos Cruz, and Juan de Borgoña (father of Felipe). To the two first-named may be attributed the ten panels of the lowest stage, representing Saints Peter and Paul, the Four Evangelists, and Four Doctors of the Church, and the Transfiguration, Annunciation, Nativity, Adoration of the Magi, and Presentation in the Temple, in the second stage. To Borgoña we may ascribe the Agony in the Garden, the Scourging, Crucifixion, Descent into Hell, and Resurrection, in the third stage. To the right and left of the church are two beautiful Renaissance retablos in alabaster, illustrating the lives of Saints Secundus and Catharine, and two tasteful gilt iron pulpits. The light reaches the High Altar through two rows of thirteen windows, the lower ‘round-arched, of two horseshoe-headed lights divided by a shafted monial,’ and the upper ‘round-headed, broadish windows, with jamb-shafts and richly-chevroned arches.’ The fine stained glass is the work of Albert of Holland (1520-1525).

The choir was placed in the easternmost bay of the nave in 1531. The trascoro or back of the choir is adorned with reliefs of the Adoration of the Magi, the Massacre of the Innocents, and the Presentation; smaller panels represent other scenes from the history of Christ and the Blessed Virgin. The frieze with its fourteen figures of prophets is the finest part of the work. The choir stalls were begun in 1527 by Juan Rodrigo, and completed by Cornelius of Holland in 1536. The carving is of varying merit. The upper panels appear to portray the martyrdoms of different saints, episodes in whose lives are shown on the panels below. The ornamentation of the columns and friezes is profuse and delicately done.

In the south transept is the fine tomb of Don Sancho Davila, Bishop of Sigüenza, who died in 1534, and near him that of a namesake, whose effigy is clad in armour. This knight died before the walls of Alhama in a combat so furious that his scattered limbs had afterwards to be collected and pieced together by his friends. A curious tomb is to be seen near by: the figures of a knight in armour and an ecclesiastic repose on black coffins, the sides of which are sculptured with escutcheons upheld by woolly-haired savages; a monkey is seen pulling the negroes’ hair. In the chapel of San Miguel, at the north-west end of the nave, is an interesting tomb of the thirteenth century, representing a funeral, whereat the anguish of the mourners contrasts strikingly with the stoical indifference of the clergy.

The gorgeous chapel of San Segundo at the south-east of the apse, outside the town wall, was founded in 1595 by Bishop Manrique, on the model, it is said, of the Escorial. Magnificence, rather than good taste, characterises this chapel and its furniture. Frescoes by Francisco Llamas illustrate the life of the saint, whose ashes are contained in a Churrigueresque tabernacle. On the opposite side of the apse, but within the wall, is another excrescence, the Velada chapel, completed in the eighteenth century.

The sacristy is an ornate Renaissance structure, richly gilded and painted. The alabaster retablo over the altar of St. Barnabas is the work of a genius whose name unfortunately has not been handed down. The chamber also contains some curious fifteenth-century paintings relating to the life of St. Peter. Here may be seen the superb monstrance of Juan de Arfe, dated 1574, and therefore among his earliest works.

The cloister on the south side of the cathedral was built in the early sixteenth century on the site of an earlier one. There was an attempt made at the same time to restore, more or less at haphazard, all the tombs and epitaphs left from earlier times. At the angles are chapels, one of which, the Piedad, contains some good stained glass and iron-work. East of the cloister is the spacious apartment called the Cardinal’s Chapel, after Cardinal Davila y Mujica, whose tomb it contains. Here met the Junta of the Comuneros. The fine stained glass in the windows shows the skill of Juan de Santillana and Juan de Valdevieso, two famous glass-workers of Burgos.

In some respects more interesting than the cathedral, and probably more ancient, taken as a whole, is the Romanesque church of San Vicente, outside the walls, near the Segovia gate. It marks the site of the martyrdom of Vicente and his sisters, Sabina and Cristeta, who had taken refuge here to escape the persecution of Dacian, at the beginning of the fourth century. Their religion having been discovered, they were again apprehended, and put to death by their skulls being battered against the rocks. Their bodies were left unburied, but a great serpent came out of a hole near by and protected them from insult. A Jew approached the spot, led by spiteful curiosity, and was seized by the monster, which wound its coils about him. The terrified Hebrew invoked the name of Christ and was released. He was baptized, and secretly gave the martyrs honourable burial, subsequently raising a church over the scene of their martyrdom. So runs the tradition. These dissenters from the state religion of the Roman Empire are remembered and revered to this day, and magnificent fanes are rightly raised over their graves. Their ashes are preserved in reliquaries more costly than royal thrones, and kings kneel before their shrines. But no monuments are erected, no reverence paid to the equally high-minded and courageous dissenters from the state religion of the Spanish monarchy, who perished in the flames kindled by the Inquisition. The very city which delighted to honour Vicente and his sisters, and recorded its detestation of the lawful authority that put them to death, was the seat of the dreadful tribunal of Torquemada and the scene of cruelties worse than any perpetrated by the Romans.
