Nicole Belayche is professor emerita at the École Pratique des Hautes Études, PSL (Paris). Her research interests include pagan cults in the Roman Empire and analysis of rituals in the context of interactions, and she has recently co-edited Puissances divines à l'épreuve du comparatisme (2017).
Francesco Massa, Ph.D., is assistant professor at the University of Fribourg. He is specialised in religious interactions in the Roman Empire, and is the author of Tra la vigna e la croce. Dioniso nei discorsi letterari e figurativi cristiani (2014).

This book fills a gap in the study of mystery cults in Graeco-Roman Antiquity. Focusing on the visual language surrounding these cults, it aims to understand how images depict mysteries in different cults: Dionysus, Mithras, Mother of the Gods, and Isiac cults.
