It cannot be doubted that there were various ways of interaction between different groups in Graeco-Roman Egypt, as a number of more or less recent regional studies have further reinforced. And as is well-known, Egypt emerges as a sort of exception in the study of ancient cultures and religions, providing scholars with the possibility of relying on a great number and variety of documents. Exploring interactively the diversity of documentary material is the main aim of this volume. In socio-cultural terms, such an analysis corroborates the image of Egypt as a pervasive cultural system where for many centuries different elites coagulated themselves around a number of standard modalities to produce cultural and religious micro-systems. This shows that people, even when different languages and textual practices survive, respond to specific modalities of cohabitation under the umbrella of this hegemonic cultural field.
