By these means prosperity and abundance prevailed in this beautiful city; its gates were thronged with commerce, and its warehouses filled with luxuries and merchandise of every clime and country. He moreover gave premiums and privileges to the best artisans; improved the breed of horses and other domestic animals; encouraged husbandry; and increased the natural fertility of the soil twofold by his protection, making the lovely valleys of his kingdom to bloom like gardens. He fostered also the growth and fabrication of silk, until the looms of Granada surpassed even those of Syria in the fineness and beauty of their productions. He moreover caused the mines of gold and silver and other metals, found in the mountainous regions of his dominions, to be diligently worked, and was the first king of Granada who struck money of gold and silver with his name, taking great care that the coins should be skilfully executed. It was towards the middle of the thirteenth century, and just after his return from the siege of Seville, that he commenced the splendid palace of the Alhambra; superintending the building of it in person; mingling frequently among the artists and workmen, and directing their labors. Though thus magnificent in his works and great in his enterprises, he was simple in his person and moderate in his enjoyments. His dress was not merely void of splendor, but so plain as not to distinguish him from his subjects. His harem boasted but few beauties, and these he visited but seldom, though they were entertained with great magnificence. His wives were daughters of the principal nobles, and were treated by him as friends and rational companions. What is more, he managed to make them live in friendship with one another. He passed much of his time in his gardens; especially in those of the Alhambra, which he had stored with the rarest plants and the most beautiful and aromatic flowers. Here he delighted himself in reading histories, or in causing them to be read and related to him, and sometimes, in intervals of leisure, employed himself in the instruction of his three sons, for whom he had provided the most learned and virtuous masters.
