Rabbi Moshe Ben Maimon (1135–1204) was a Cordova-born polymath famous for his rationalist approach to religion and life (he was fond of quoting Aristotle). The nearby Maimonides Heritage Center has exhibits on the sage's life and writings.
The Rambam's most famous works are the Mishneh Torah, the first systematic codification of Jewish law; Guide to the Perplexed, a work of theology, written in Arabic, that is still hugely influential today; and various books on medicine (he served as the personal physician of the sultan of Egypt, where he spent the last decades of his life).
