Pedro built more than one palace, or, more correctly, two or three wings of the same palace, in this enclosure. Traces of his Stucco Palace (Palacio del Yeso) remain. Pedro looms very large in the history of Seville. He plays as prominent a part here as Harûn-al-Rashid in the story of Bagdad. He was fond of the Moors, and affected their costumes and customs. He also favoured the Jews, and was alleged by his enemies to be the changeling child of a Jewess. His treasurer and trusted adviser was an Israelite named Simuel Ben Levi. He served the king long and faithfully, till one day it was whispered that half the wealth that should fill the royal coffers had been diverted into his own. Ben Levi was seized without warning and placed on the rack, whereupon he expired, not of pain, but of sheer indignation. Under his house--so the story goes--was found a cavern in which were three piles of gold and silver, twice as high as a man. Pedro on beholding these was much affected. "Had Simuel surrendered a third of the least of these piles," he exclaimed, "he should have gone free. Why would he rather die than speak?" Stories innumerable are told of this king, a good many, no doubt, being pure inventions. There is no reason to question the account of his treatment of Abu Saïd, the Moorish Sultan of Granada. This prince had usurped the throne, and being solicitous of Pedro's alliance, came to visit him at the Alcazar with a magnificent retinue. The costliest presents were offered to the Castilian king, whose heart, however, was bent on possessing the superb ruby in the regalia of his guest. Before many hours had passed, the Moors were seized in their apartments and stripped of their raiment and valuables. Abu Saïd, ridiculously tricked out, was mounted on a donkey, and with thirty-six of his courtiers, hurried to a field outside the town, where they were bound to posts. A train of horsemen appeared, Don Pedro at their head, and transfixed the helpless men with darts, the king shouting, as he hurled his missiles at his luckless guest: "This for the treaty you made me conclude with Aragon! This for the castle you took from me!" The ruby which had been the cause of the Moor's death was presented by his murderer to the Black Prince, and now adorns the crown of England.
