Concentrating on the states of the issues being discussed and researched in the field of Semitic linguistics, this new collection of articles combines the input of top scholars in their areas of expertise with topics under discussion and current research. IOS 20 is a vital addition for research libraries, linguists, biblical and ancient Near Eastern scholars. Israel Oriental Studies has ceased publication with volume 20.

Islam has always had ambivalent relations with Judaism and Christianity, as also with Jews and Christians. The awkwardness of their character has been accentuated by the creation and perpetuation, on all sides, of partial and ill-intentioned images during the middle ages and by political developments in the modern period. Since the beginning of serious modern study of Islam in the west, these relations have found an important place in scholars' interest, partly because many of those in the west who have studied Islam have been Jews, with a natural attraction to an interest in those topics which affected Jews and other minorities in the Islamic environment. In this volume, we have tried to assemble a collection of papers which reflect something of the diversity of the problems offered by this range of relations. We have also attempted to reflect, in the variety of the papers and the topics discussed in them, the rich variety of approach adopted by scholars over the last century and a half of such study. Israel Oriental Studies has ceased publication with volume 20.

Sociology of Shiʿite Islam is a comprehensive study of the development of Shiʿism. Its bearers first emerged as a sectarian elite, then a hierocracy and finally a theocracy. Imamate, Occultation and the theodicy of martyrdom are identified as the main components of the Shiʻism as a world religion. In these collected essays Arjomand has persistenly developed a Weberian theoretical framework for the analysis of Shiʿism, from its sectarian formation in the eighth century through the establishment of the Safavid empire in the sixteenth century, to the Islamic revolution in Iran in the twentieth century. These studies highlight revolutionary impulses embedded in the belief in the advent of the hidden Imam, and the impact of Shiʻite political ethics on the authority structure of pre-modern Iran and the constitution of the Islamic Republic of Iran.

Being direct descendants of the Aramaic spoken by the Jews in antiquity, the still spoken Jewish Neo-Aramaic dialects of Kurdistan deserve special and vivid interest. Geoffrey Khan’s A Grammar of Neo-Aramaic is a unique record of one of these dialects, now on the verge of extinction. This volume, the result of extensive fieldwork, contains a description of the dialect spoken by the Jews from the region of Arbel (Iraqi Kurdistan), together with a transcription of recorded texts and a glossary. The grammar consists of sections on phonology, morphology and syntax, preceded by an introductory chapter examining the position of this dialect in relation to the other known Neo-Aramaic dialects. The transcribed texts record folktales and accounts of customs, traditions and experiences of the Jews of Kurdistan.

An integrative approach to Jewish and Muslim philosophy in al-Andalus Al-Andalus, the Iberian territory ruled by Islam from the eighth to the fifteenth centuries, was home to a flourishing philosophical culture among Muslims and the Jews who lived in their midst. Andalusians spoke proudly of the region's excellence, and indeed it engendered celebrated thinkers such as Maimonides and Averroes. Sarah Stroumsa offers an integrative new approach to Jewish and Muslim philosophy in al-Andalus, where the cultural commonality of the Islamicate world allowed scholars from diverse religious backgrounds to engage in the same philosophical pursuits. Stroumsa traces the development of philosophy in Muslim Iberia from its introduction to the region to the diverse forms it took over time, from Aristotelianism and Neoplatonism to rational theology and mystical philosophy. She sheds light on the way the politics of the day, including the struggles with the Christians to the north of the peninsula and the Fāṭimids in North Africa, influenced philosophy in al-Andalus yet affected its development among the two religious communities in different ways. While acknowledging the dissimilar social status of Muslims and members of the religious minorities, Andalus and Sefarad highlights the common ground that united philosophers, providing new perspective on the development of philosophy in Islamic Spain.

The Gnostic World is an outstanding guide to Gnosticism, written by a distinguished international team of experts to explore Gnostic movements from the distant past until today. These themes are examined across sixty-seven chapters in a variety of contexts, from the ancient pre-Christian to the contemporary. The volume considers the intersection of Gnosticism with Jewish, Christian, Islamic and Indic practices and beliefs, and also with new religious movements, such as Theosophy, Scientology, Western Sufism, and the Nation of Islam. This comprehensive handbook will be an invaluable resource for religious studies students, scholars, and researchers of Gnostic doctrine and history.

Volume 5 examines the history of Judaism in the Islamic World from the rise of Islam in the early sixth century to the expulsion of Jews from Spain at the end of the fifteenth. This period witnessed radical transformations both within the Jewish community itself and in the broader contexts in which the Jews found themselves. The rise of Islam had a decisive influence on Jews and Judaism as the conditions of daily life and elite culture shifted throughout the Islamicate world. Islamic conquest and expansion affected the shape of the Jewish community as the center of gravity shifted west to the North African communities, and long-distance trading opportunities led to the establishment of trading diasporas and flourishing communities as far east as India. By the end of our period, many of the communities on the 'other' side of the Mediterranean had come into their own—while many of the Jewish communities in the Islamicate world had retreated from their high-water mark.

This volume consists of an edition, translated into English and with an extensive introduction, of the Arabic translation and commentary on the book of Esther by one of the preeminent litterateurs of the Karaite “Golden Age” (10th–11th centuries), Yefet ben ‘Eli ha-Levi. Yefet’s text represents the first completely extant, devoted commentary on Esther and, consequently, provides fascinating insight into the history and development of exegetical thought on this book, both among the Karaites as well as the Rabbanites. Various facets of Yefet’s exegesis which we explore in our introduction include his rationalistic method, compilatory tendency, relationship to the doctrines of the Islamic Mu‘tazila, and his influence both by and upon other Jewish exegetes (Karaite and Rabbanite). We also assess Yefet’s Arabic translation technique and include a survey of all extant Karaite commentaries on Esther, both in Arabic as well as Hebrew. "At first sight, the book stands out as a model of systematic organization and thoroughness in treatment of detail...Wechsler has given us a detailed survey of the place of Yefet in the history of Karaite exegesis and in the history of Karaite theoretical argument." - I.R.M. Bóid "Altogether, this book may be considered an important step forward in the availability of Yefet ben 'Eli's commentaries in critical editions and will serve as a standard for future publications of his vast exegetical oeuvre." - Ronny Vollandt, University of Cambridge
