Abstract: This article investigates what it means for the Virgin Mary to be a common figure between Christianity and Islam. Departing from approaches which emphasize the textual biography and personality of figural saints, it explores the Virgin as a contested image of divine intercession among Muslims and Christians on the ground. Beginning with lived contexts of everyday mediation, it thus situates the “commonness” of the Virgin within the thick practical realities of modern communication and imagination. More specifically, it probes one ethnographic case of a Marian apparition which occurred in Giza in 2009, producing eyewitness observation and critical reflection. My aim is to show how the historical phenomenon of “collective apparitions” provides a distinctive visual-cultural platform for evaluating the communicatively public aspects of saintly mediation. In doing so, this study concretely traces how growing cults of the Virgin Mary shape newly widespread practices of religious identification and differentiation among contemporary Orthodox, Protestants, and Muslims in Egypt.
