XV. Gil Díaz did his best endeavour to fulfil all that his Lord the Cid Ruydiez had commanded him, and to serve Doña Ximena and her companions truly and faithfully; and this he did so well, that she was well pleased with his faithfulness. And Doña Ximena fulfilled all that the Cid had commanded her; and every day she had masses performed for his soul, and appointed many vigils, and gave great alms for the soul of the Cid and of his family. And this was the life which she led, doing good wherever it was needful for the love of God; and she was alway by the body of the Cid, save only at meal times and at night, for then they would not permit her to tarry there, save only when vigils were kept in honour of him. Moreover Gil Diaz took great delight in tending the horse Bavieca, so that there were few days in which he did not lead him to water, and bring him back with his own hand. And from the day in which the dead body of the Cid was taken off his back, never man was suffered to bestride that horse, but he was alway led when they took him to water, and when they brought him back. And Gil Diaz thought it fitting that the race of that good horse should be continued, and he bought two mares for him, the goodliest that could be found, and when they were with foal, he saw that they were well taken care of, and they brought forth the one a male colt and the other a female; and from these the race of this good horse was kept up in Castille, so that there were afterwards many good and precious horses of his race, and peradventure are at this day. And this good horse lived two years and a half after the death of his master the Cid, and then he died also, having lived, according to the history, full forty years. And Gil Diaz buried him before the gate of the Monastery, in the public place, on the right hand; and he planted two elms upon the grave, the one at his head and the other at his feet, and these elms grew and became great trees, and are yet to be seen before the gate of the Monastery. And Gil Diaz gave order that when he died they should bury him by that good horse Bavieca, whom he had loved so well.
