Crossing Borders tells the intriguing but largely unfamiliar story of the exchange of culture and knowledge between Jews and non-Jews in the Muslim and Christian worlds during the late Middle Ages as part of the preparation of Hebrew manuscripts.  The book is composed of ten narratives, each of which brings to light a different aspect of Jewish life in a non-Jewish medieval society—highlighting the practical cooperation, social interaction, and religious toleration that was surprisingly common between the groups involved in the early enterprise of book production.

            Alongside the narratives, Crossing Borders is beautifully illustrated with images from the Hebrew holdings at the Bodleian Library—one of the largest and most important collections of Hebrew manuscripts worldwide. The art includes Christian codex fragments from the third century, a copy of Moses Maimonides’ Mishneh Torah signed by Maimonides himself, a thirteenth century German Jewish prayer book, and lavishly illuminated Spanish Bible manuscripts from the fifteenth century. This exquisitely illustrated book takes a fascinating look at the often-ignored role of Jews in the written transmission of culture and science throughout medieval Europe.

The Leipzig Mahzor is one of the most lavish Hebrew illuminated manuscripts of all time. A prayer book used during Jewish holidays, it was produced in the Middle Ages for the Jewish community of Worms in the German Rhineland. Though Worms was a vibrant center of Judaism in the eleventh and twelfth centuries and drew celebrated rabbis, little is known about the city's Jews in the later Middle Ages. In the pages of its famous book, Katrin Kogman-Appel discovers a portal into the life of this fourteenth-century community.

Medieval mahzorim were used only for special services in the synagogue and "belonged" to the whole congregation, so their visual imagery reflected the local cultural associations and beliefs. The Leipzig Mahzor pays homage to one of Worms's most illustrious scholars, Eleazar ben Judah. Its imagery reveals how his Ashkenazi Pietist worldview and involvement in mysticism shaped the community's religious practice. Kogman-Appel draws attention to the Mahzor's innovations, including its strategy for avoiding visual representation of God and its depiction of customs such as the washing of dishes before Passover, something less common in other mahzorim. In addition to decoding its iconography, Kogman-Appel approaches the manuscript as a ritual object that preserved a sense of identity and cohesion within a community facing a wide range of threats to its stability and security.

After the Bible, the Passover haggadah is the most widely read classic text in the Jewish tradition. More than four thousand editions have been published since the late fifteenth century, but few are as exquisite as the Washington Haggadah, which resides in the Library of Congress. Now, a stunning facsimile edition meticulously reproduced in full color brings this beautiful illuminated manuscript to a new generation.

Joel ben Simeon, the creator of this unusually well-preserved codex, was among the most gifted and prolific scribe-artists in the history of the Jewish book. David Stern’s introduction reconstructs his professional biography and situates this masterwork within the historical development of the haggadah, tracing the different forms the text took in the Jewish centers of Europe at the dawn of modernity.

Katrin Kogman-Appel shows how ben Simeon, more than just a copyist, was an active agent of cultural exchange. As he traveled between Jewish communities, he brought elements of Ashkenazi haggadah illustration to Italy and returned with stylistic devices acquired during his journeys. In addition to traditional Passover images, realistic illustrations of day-to-day life provide a rare window into the world of late fifteenth-century Europe.

This edition faithfully preserves the original text, with the Hebrew facsimile appearing in the original right-to-left orientation. It will be read and treasured by anyone interested in Jewish history, medieval illuminated manuscripts, and the history of the haggadah.
