  The Ibn Tibbon dynasty of translators was instrumental in creating a philosophical library in Hebrew. They also developed a technical terminology, which was used by translators, philosophers, and commentators throughout the Middle Ages. Perhaps more significant, however, were their contributions as original authors. Thus Samuel and Moses wrote philosophical commentaries on the Bible and rabbinic literature and philosophical-exegetical monographs, while Jacob Anatoli wrote a collection of philosophical sermons. These writings, inspired by the work of Maimonides and saturated with the philosophy of al-Farabi and Averroes, laid the foundations for a whole movement of Jewish philosophy and exegesis: Maimonideanism. This movement attracted enthusiasts in Provence, as well as in Italy, Byzantium, and to a lesser extent Spain. It exercised influence and caused controversy throughout the thirteenth and fourteenth centuries and even into the fifteenth, when Jewish philosophy gradually turned to Christian-Latin rather than Graeco-Arabic and Arabic sources for inspiration.
