The show is a rare offering and an archaeological detective story. And what an extraordinary revelation “The World of the Fatimids” proves to be. Upon entering, the visitor sees the three monotheistic religions juxtaposed: a glazed earthenware bowl depicting a Coptic priest; beyond it, a beautifully carved wooden Ismaili mihrab (Muslim prayer niche); and nearby the photo of a wooden synagogue door carving - all objects from Fatimid times.
