"This study of Yiddish texts dating from 1100 to 1750 is the definitive work in the field. Frakes is at home in the classics, medieval studies, German studies, comparative religion, and Hebrew and Yiddish, and he brings to this historical study of many of the same texts the impeccable scholarship characteristic of his previous works."-- Choice "Jerold Frakes offers an excellent presentation of the Jewish vernacular as a multi-faceted, multivalent cultural phenomenon that shows the slow religious evolution and socio-cultural turn from the Middle Ages to the Early Modern period."--Jean Baumgarten, author of Introduction to Old Yiddish Literature "Jerold Frakes raises particularly poignant questions on how the work of Christians influenced Jewish society."--Edward Fram, author of My Dear Daughter: Rabbi Benjamin Slonik and the Education of Jewish Women in Sixteenth-Cen.
