In his academic career, that by now spans six decades, Daniel J. Lasker distinguished himself by the wide range of his scholarly interests. In the field of Jewish theology and philosophy he contributed significantly to the study of Rabbinic as well as Karaite authors. In the field of Jewish polemics his studies explore Judeo-Arabic and Hebrew texts, analyzing them in the context of their Christian and Muslim backgrounds. His contributions refer to a wide variety of authors who lived from the 9th century to the 18th century and beyond, in the Muslim East, in Muslin and Christian parts of the Mediterranean Sea, and in west and east Europe. This Festschrift for Daniel J. Lasker consists of four parts. The first highlights his academic career and scholarly achievements. In the three other parts, colleagues and students of Daniel J. Lasker offer their own findings and insights in topics strongly connected to his studies, namely, intersections of Jewish theology and Biblical exegesis with the Islamic and Christian cultures, as well as Jewish-Muslim and Jewish-Christian relations. Thus, this wide-scoped and rich volume offers significant contributions to a variety of topics in Jewish Studies.
