Handbooks devoted to a single area of ritual practice figure prominently among the works produced by German Jews from the thirteenth century to the fifteenth. These handbooks include minhagim books intended primarily as liturgical guides for cantors and manuals for other types of communal functionaries, such as scribes and ritual slaughterers. Historians typically associate minhagim books with the post–Black Death period and the desire to provide guidance during a time of decline for German Jewry. Similarly, the flourishing of halakhic manuals is considered a fourteenth-century phenomenon, a result of the rabbinate’s professionalization. However, these explanations are insufficient since both genres emerged earlier. This article links the production of ritual handbooks to two trends: geographic mobility and a more text-oriented culture. Between the thirteenth century and the fifteenth, major changes in German Jewish settlement patterns disrupted the transmission of ritual practice and led to a need for practical guides. The proliferation of ritual handbooks was also related to the increase in Ashkenazic society—as in medieval Europe generally—in the production of written texts. These texts included liturgical genres and practical halakhic works, some of which served as sources for the handbooks. However, the handbooks tend to be more accessible than their predecessors and to include more practical details. The proliferation of late medieval ritual handbooks demonstrates that changes typically associated with the advent of print, including a growing reliance on written sources for practical information and a move toward the standardization of ritual practice, began to emerge in earlier centuries.
