Byzantine Studies have reached a high level of scholarship in the international academic scene, especially in the European and North American continents; one could not yet say the same with regard to the relations of these studies with the Arab and the Islamic world. Religious Studies (Religionswissenschaft) have also reached an impressive level of breath and maturation; not so, again, with regard to the relations of Byzantine Christianity with Islam — not an insignificant connection in the context of world history and civilization, interreligious encounter, cross-fertilization, interaction and dialogue.
