Castile, but were not unheard of either. Abraham Zacuto was a professor at the university of Cartagena. Vidal Astori was the royal silversmith for Ferdinand II of Aragon and conducted business in his name. And King Ferdinand himself was said to have remote Jewish ancestry on his mother's side. Medieval Inquisition in Castile There was never a tribunal of the Papal Inquisition in Castile, nor any inquisition during the Middle Ages. Members of the episcopate were charged with surveillance of the faithful and punishment of transgressors, always under the direction of the king. During the Middle Ages in Castile, the Catholic ruling class and the population paid little or no attention to heresy. Castile did not have the proliferation of anti-Jewish pamphlets as England and France did during the 13th and 14th centuries—and those that have been found were modified, watered-down versions of the original stories. Jews and Muslims were tolerated and generally allowed to follow their traditional customs in domestic matters. The legislation regarding Muslims and Jews in Castilian territory varied greatly, becoming more intolerant during the period of great instability and dynastic wars that occurred by the end of the 14th century. Castilian law is particularly difficult to summarize since, due to the model of the free Royal Villas, mayors and the population of border areas had the right to create their own fueros (law) that varied from one villa to the next. In general, the Castilian model was parallel to the initial model of Islamic Spain. Non-Catholics were subject to discriminatory legislation regarding taxation and some other specific discriminatory legislation—such as a prohibition on wearing silk or "flashy clothes"—that varied from county to county, but were otherwise left alone. Forced conversion of minorities was against the law, and so was the belief in the existence of witchcraft, oracles or similar superstitions. In general, all "people from the book" were permitted to practice their own customs and religions as far as they did not attempt proselytizing on the Christian population. Jews particularly had surprising freedoms and protections compared with other areas of Europe and were allowed to hold high public offices such as the counselor, treasurer or secretary for the crown. During most of the medieval period, intermarriage with converts was allowed and encouraged. Intellectual cooperation between religions was the norm in Castile. Some examples are the Toledo School of Translators from the 11th century. Jews and Moors
