When the Fatimid Dynasty dissolved during the twelfth century, the libraries and collections of books that existed in Cairo were dispersed, making it difficult to locate any complete manuscripts.[13] Only fragments of text and paper are able to provide information of the content and style of Fatimid manuscripts. It is rare to have an example of both text and illustrations of the same page, which makes it difficult to gather information about illuminated manuscripts. In some cases, it is possible that illustrations were added to an already existing text at a later date.[12] Fatimid illustration style can be demonstrated by one surviving piece of paper, which was excavated in Cairo.
