I. King Don Ferrando succeeded to the states of Castille after the death of his father King Don Sancho el Mayor, in the era 1072, which was the year of the Incarnation 1034, and from the coming of the Patriarch Tubal to settle in Spain 3197, and from the general deluge 3339, and from the creation of the world 4995, according to the computation of the Hebrews, and from the beginning of the false sect of the Moors 413. And in the year 1037 Ferrando slew Bermudo the King of Leon in battle, who was his wife's brother, and conquered his kingdom, and succeeded to it in right of his wife Doña Sancha. So he was the first person who united the states of Castille and Leon, and the first who was called King of Castille; for till this time the lords of that country had been called Counts. He was a good king, and one who judged justly and feared God, and was bold in all his doings. Before he reigned he had by Doña Sancha his wife the Infanta Doña Urraca, his eldest daughter, who was a right excellent lady, of good customs and bounty and beauty; and after her he had the Infante Don Sancho, his eldest son and heir; and then the Infanta Doña Elvira, whom after the death of the King her father, her brother King Don Alfonso married to the Count Don Garci de Cabra. And after he became King he had the Infante Don Alfonso, and the Infante Don Garcia, who was the youngest of all. And he put his sons to read, that they might be of the better understanding, and he made them take arms, and be shown how to demean themselves in battle, and to be huntsmen. And he ordered that his daughters should be brought up in the studies beseeming dames, so that they might be of good customs, and instructed in devotion and in all things which it behoved them to know.
