Ateret Zekenim is a work of historical research into the lives of several well-known medieval halakhists from France, Germany, and Spain. The primary focus of the book is biographical, and it attempts to resolve difficult questions that have puzzled the scholarly community for many years. Its author seeks to rely on the writings of his predecessors, but he first substantiates that these foundations were properly laid and that he is not adding to an edifice that is destined to collapse. Thus, for example, the author re-examines the story of Rabbi Asher b. Yeḥiel (Rosh)’s migration from Germany to Spain in the early 14th century, a migration that had a dramatic impact on the culture of Sephardi and Ashkenazi Jewry alike. Is the scholarly consensus – according to which Rosh meticulously planned his flight to distant Toledo, in an entirely different cultural realm, over the course of two decades – correct? After methodical examination of the sources, a very different story emerges. Rosh, and with him the Ashkenazi halakhic tradition, moved from Germany to Spain at the last moment, when there were no other options.

The purpose of this volume, like its predecessor, is to uncover fragments of important Hebrew works hidden in the “European Genizah”. Thousands of pages of Hebrew manuscripts have been discovered in this “Genizah”, which is scattered in hundreds of libraries and archives throughout Europe and even beyond. In the late medieval and early modern eras, these pages were used to bind books and as folders of archival documents. The nine works published herein are from a variety of genres: Biblical exegesis, Talmud commentary, halakhic literature, and liturgical interpretation. They appear in this volume in chronological order, from earliest to latest. The most significant of the works is also the work whose discovery required more effort than all of the others; it appears in the first chapter of the book. This work was written in ninth or tenth-century Palestine. It reveals valuable information on the history of halakhah in Palestine of that era, and also teaches a great deal about how Palestinian Traditions made their way to the European continent.

The discovery of the Cairo Geniza has transformed scholarly research in multiple areas of Jewish Studies and revolutionized several disciplines. It has provided the materials for thousands of studies and is by no means exhausted. Alongside the Cairo Geniza, an additional "Geniza" is slowly emerging in Europe, one that consists of many thousands of individual pages that were torn from Hebrew manuscripts hundreds of years ago and subsequently used for bookbinding and as folders for archive files. Although the first fruits of the European Geniza appeared considerably before the discovery of its Cairo counterpart, this "European Geniza" has not been at the center of scholarly interest, and relatively few scholars have made use of it. However, in recent decades thousands of new fragments have come to light, increasing the quantity previously known to us exponentially. Hidden Treasures from Europe seeks to bring the European Geniza to the forefront of scholarly research. Chapter One is an extensive and detailed introduction to the nature of this Geniza. The heart of the book, Chapters Two through Twelve, comprises the first publication of eleven important texts found in the European Geniza that are not extant in published editions or in whole manuscripts. These were carefully chosen from among a much broader range of previously unknown texts that were preserved in the European Geniza. Half of these compositions are Bible commentaries (Section I, Chapters Two–Six), and the other half are commentaries to the Talmud (Section II, Chapters Seven–Twelve). Most were composed in France, Germany, or Italy, while the country of origin of one early work, Sefer efeî, has yet to be determined.

Tarbiz is the only Hebrew academic journal that is devoted to the entire range of Jewish studies. Appearing quarterly, this journal is the principal forum for the expression of the most important developments in Jewish studies in our generation, and its contributors include the leading scholars in the various fields of Jewish studies in Israel and the world, as well as young scholars who are beginning to make their mark. Tarbiz was first published in 1930 at the Institute of Jewish Studies at the Hebrew University of Jerusalem, under the editorial pen of Prof. Jacob Nachum Epstein z"l.

The Torah of the Ba'aeli Tosaphists-the scholars of Germany and France in the 12th and 13th Century, is the iron pillar of the Halacha and the Jewish law.
