Christian Calendars in Medieval Hebrew Manuscripts
The phenomenon of Christian calendars in Hebrew has largely been ignored in modern scholarship; yet it points to an important dimension of Jewish Christian relations, and more specifically Jewish attitudes towards Christianity, in late medieval northern Europe. It is also evidence of transfer of religious knowledge between Christians and Jews, because the Hebrew texts closely replicate, in contents as well as in layout and presentation, the Latin liturgical calendars, which in many cases the Hebrew scribes must have used directly as base texts. Knowledge of the Christian calendar was essential to Jews for dating documents, especially (but not exclusively) those intended for Christians, for understanding dates in documents, for scheduling business or other meetings with Christians, and in short, for effectively coordinating their socio economic activities with the rhythms and structure of Christian medieval life.
