Written in Arabic in the first half of the ninth century, Twenty Chapters is the first medieval Jewish philosophical work, and had a major influence on the development of Jewish theological and philosophical thought. Dawūd al-Muqammaṣ, a Jewish convert to Christianity, who wrote this theological Summa after his return to Judaism, also authored the first Judeo-Arabic Bible commentaries, and some of the earliest Judeo-Arabic polemical works. The annotated Hebrew translation of this pioneering work, published here for the first time, presents al-Muqammaṣ in his intellectual and historical context and throws light on his Jewish, Muslim and Christian background.

This book offers a cultural biography of Maimonides as a product of his multi-cultural and multi-religious background. It studies “the great eagle” in his multi-faceted historical and cultural context, and highlights the deep impact on him of Islamic culture as a whole: not only his philosophy, but also his legal and scientific writings as well as his correspondences. The aim of the book is twofold. On the one hand, it highlights universal patterns in Maimonides’ thought. On the other hand, it shows Maimonides’ relevance to the study of Medieval Islam. The presentation of Maimonides as a Mediterranean thinker elucidates his consistent interpretation of his own Jewish tradition in contemporary terms, as they were shaped by his Mediterranean legacy.

This volume covers some fifty years of Pines' work in the field of Islamic philosophy, from the very first article he published ("Some Problems of Islamic Philosophy", in 1937") to an article that was found in his paper after his death and is published here for the first time (" The origin of the Tale of Salâmân and Absâl").
