The Cairo Geniza, alternatively spelled Genizah, is a collection of some 400,000 Jewish manuscript fragments and Fatimid administrative documents that were found in the genizah or storeroom of the Ben Ezra Synagogue in Fustat or Old Cairo, Egypt. These manuscripts outline a 1,000-year continuum of Jewish Middle-Eastern and North African history and comprise the largest and most diverse collection of medieval manuscripts in the world. The Genizah texts are written in various languages, especially Hebrew, Arabic and Aramaic, mainly on vellum and paper, but also on papyrus and cloth. In addition to containing Jewish religious texts such as Biblical, Talmudic and later Rabbinic works, the Genizah gives a detailed picture of the economic and cultural life of the North African and Eastern Mediterranean regions, especially during the 10th to 13th centuries. It is now dispersed among a number of libraries, including the libraries of Cambridge University, the Jewish Theological Seminary of America, the University of Manchester, and in the Antonin Cairo Genizah Collection in Saint Petersburg. Some additional fragments were found in the Basatin cemetery east of Old Cairo, and the collection includes a number of old documents bought in Cairo in the latter nineteenth century.
