'Abd al-Rahman's court physician and minister was Hasdai ibn Shaprut, the patron of Menahem ben Saruq, Dunash ben Labrat and other Jewish scholars and poets. In following centuries, Jewish thought flourished under famous figures such as Samuel Ha-Nagid, Moses ibn Ezra, Solomon ibn Gabirol and Judah Halevi. During 'Abd al-Rahman's term of power, the scholar Moses ben Hanoch was appointed rabbi of Córdoba, and as a consequence al-Andalus became the center of Talmudic study, and Córdoba the meeting-place of Jewish savants.
