This had no permanent influence on the condition of the Spanish Hebrews. During the long reigns of San Fernando III and Alfonso X of Castile and of Jaime I of Aragon, covering the greater part of the thirteenth century, the services which they rendered to the monarchs were repaid with increasing favor and protection. After Jaime had conquered Minorca he took, in 1247, all Jews settling there under the royal safeguard and threatened a fine of a thousand gold pieces for wrong inflicted on any of them and, in 1250, he required that Jewish as well as Christian testimony must be furnished in all actions, civil or criminal, brought by Christians against Jews. So, when in 1306 Philippe le Bel expelled the Jews from France and those of Majorca feared the same fate, Jaime II reassured them by pledging the royal faith that they should remain forever in the land, with full security for person and property, a pledge confirmed, in 1311, by his son and successor Sancho.[266] In Castile, when San Fernando conquered Seville, in 1244, he gave to the Jews a large space in the city, and, in defiance of the canons, he allotted to them four Moorish mosques to be converted into synagogues, thus founding the aljama of Seville, destined to a history so deplorable. Alfonso X, during his whole reign, patronized Jewish men of learning, whom he employed in translating works of value from Arabic and Hebrew; he built for them an observatory in Seville, where were made the records embodied in the Alfonsine Tables; he permitted those of Toledo to erect the magnificent synagogue now known as Santa María la Blanca, and Jews fondly relate that the Hebrew school, which he transferred from Córdova to Toledo, numbered twelve thousand students.[267] He was prompt to maintain their privileges, and, when the Jews of Burgos complained that in mixed suits the alcaldes would grant appeals to him when the Christian suitor was defeated, while refusing them to defeated Jews, he at once put an end to the discrimination, a decree which Sancho IV enforced with a penalty of a hundred maravedís when, in 1295, the complaint was repeated.[268] Yet Alfonso, in his systematic code known as the Partidas, which was not confirmed by the Córtes until 1348, allowed himself to be influenced by the teachings of the Church and the maxims of the imperial jurisprudence. He accepted the doctrine of the canons that the Jew was merely suffered to live in captivity among Christians; he was forbidden to speak ill of the Christian faith, and any attempt at proselytism was punished with death and confiscation. The murder rite was alluded to as a rumor, but in case it was practised it was a capital offence and the culprits were to be tried before the king himself. Jews were ineligible to any office in which they could oppress Christians; they were forbidden to have Christian servants, and the purchase of a Christian slave involved the death punishment. They were not to associate with Christians in eating, drinking, and bathing and the amour of a Jew with a Christian woman incurred death. While Jewish physicians might prescribe for Christian patients, the medicine must be compounded by a Christian, and the wearing of the hateful distinctive badge was ordered under penalty of ten gold maravedís or of ten lashes. At the same time Christians were strictly forbidden to commit any wrong on the person or property of Jews or to interfere in any way with their religious observances, and no coercion was to be used to induce them to baptism, for Christ wishes only willing service.[269]
