Opening on to the southern aisle, opposite the Capilla de Santa Tecla, is the cruciform chapel of the Santisimo Cristo de la Agonia, containing a very ancient, curious, and (it is alleged) miraculous image of Christ. It is supposed to have been carved by the fearful Nicodemus, and to have been afterwards found floating in a boat on the sea. It is a grotesque and yet a weird and impressive object, dressed up after the ridiculous custom in Spain. The chapel of the Presentation was founded in 1519 by the Canon Gonzalo de Lerma, whose noble tomb in the centre of the chapel was executed during his lifetime by Vigarni. Another fine tomb is here--that of Canon Jacubo de Bilbao. This chapel possesses a beautiful Virgin and Child painted on a panel, probably by Sebastiano del Piombo, and sculptures by Berruguete. The railing is another example of Andino’s craftsmanship. In the chapel of San Juan de Sahagun are preserved the relics of the saint, who was a canon of Burgos. Here are also numerous other relics, chiefly fragments of the bodies of sainted personages, among them two local martyrs, Centola and Helena. The image of the Virgin of Oca is fabled to have testified by a nod to the promise of marriage made by a faithless Don Juan to a damsel--a silly story also told of the Cristo de la Vega at Toledo. Simon, the last Bishop of Oca, is buried in this chapel, and also the Blessed Lesmes, who is invoked by sufferers from nephritic disorders. More interesting than any of these things is the Cristo de la Agonia, a painting signed by El Greco. In the chapel of the Visitation is the handsome tomb of the founder, the Bishop de Cartagena; and in the seventeenth-century chapel of San Enrique repose the remains of the bishops of Oca, and those of the founder, Bishop Peralta--contained in a beautiful tomb of alabaster, beneath a superb kneeling effigy in bronze. Of alabaster is also the beautiful flooring of the chapel; and of bronze, the fine eagle lectern. We now reach the sacristy, a great part of which is in the bad style of the eighteenth century. There is some good carving, which, indeed, is not rare in Spain; but the pictures ascribed to Murillo and other masters are all very doubtful. A jasper table is among the most interesting objects. We complete the circuit of the church by a visit to the large chapel of Santiago, designed in the sixteenth century by Juan de Vallejo. It is considered to be the parish church of Burgos. The Apostle of Spain is shown on horseback on the high altar, and again on the beautiful _reja_. Here lies the Abbot of San Quirce, one of the Velasco family, beneath a tomb worthy of his illustrious ancestry. Not far off is the sarcophagus of the Astudillos, one of whom was the founder of the chapel of the Three Kings at Cologne. There are other interesting tombs in this chapel, among the oldest being that of Bishop de Villacreces, who died in 1463.
