The importance of the Cairo Geniza, a cache of texts discovered in the attic of a medieval Egyptian synagogue, goes beyond Jewish history, crossing the breadth of the medieval world and offering an intimate view of commerce, slavery, heresy and seafaring; of what people wore, ate, rode, believed and did all day; of who married whom and why; of a Shi’ite state ruling over Sunnis, Christians and Jews; and of a society that remains the best documented of its period. Students in the course will read unpublished primary sources to gain an insider’s glimpse of what we can know and can’t know in premodern history.
