Nemo Non Metuit has the ambitious goal of discussing some of the fundamental themes in the development of the idea of magic, in all its facets, in the long chronological span of the Roman world, between the 8th century BCE and the 5th century CE. At the same time, this volume is the result of a team effort that has brought together both accomplished scholars and young researchers at the beginning of their scholarly careers. Altogether, this ample work is the result of a synergy that brought together different approaches to the study of Roman magic. The broad content of this volume includes studies on magical gems of Etruscan, Greek and Phoenician background; curse tablets; amulets targeting malaria; erotic spells; the use of veneficia or poisons for magical purposes; judicial prayers in Roman Britain; witches in the literary tradition; the role of women in the matter of magic and divination; the figure of the "Orphic witch" in the age of Augustus; sorcerers and rivals of Jesus Christ; early-Christian sermons against magic and superstition; the fight of late-antique Church against magical powers. By addressing such a diverse spectrum of topics, this volume aims to challenge traditional views and open new paths of interpretation in the reconstruction of a long-term cultural-historical object such as magic in connection to the Roman civilization.
