In Individuals and Materials in the Greco-Roman Cults of Isis Valentino Gasparini and Richard Veymiers present a collection of reflections on the individuals and groups which animated one of Antiquity's most dynamic, significant and popular religious phenomena: the reception of the cults of Isis and other Egyptian gods throughout the Hellenistic and Roman worlds. These communities, whose members seem to share the same religious identity, for a long time have been studied in a monolithic way through the prism of the Cumontian category of the "e;Oriental religions"e;. The 26 contributions of this book, divided into three sections devoted to the "e;agents"e;, their "e;images"e; and their "e;practices"e;, shed new light on this religious movement that appears much more heterogeneous and colorful than previously recognized.
