The analysis of the dynamic nature of rituals has become a heuristic tool for the investigation not only of religious behaviour and beliefs, but also for the study of social practice and communication in ancient and modern societies. From public assembly gatherings and funerals to celebration of cult feasts or the honouring of individuals, rituals mark socially important occasions, define beginnings and endings, and aid social transitions. Thus, rituals carry all kinds of messages intended to support and express the performance of those involved, and to create the desired results. The present volume brings together a collection of articles on rituals in the Graeco-Roman world, focussing on the interconnection between ritual as a means of communication and communication as a ritual phenomenon. In regarding rituals as an interface in the realm of cultural practices, the contributors demonstrate the manifold function of ritual communication in the life of ancient communities.
