Book excerpt: Comparing amulets over time and space, this volume focuses on the function of written words on these fascinating artefacts. Ranging from Roman Egypt to the Middle Ages and the Modern period, this book provides an overview on these artefacts in the Mediterranean world and beyond, including Europe, Iran, and Turkey. A deep analysis of the textuality of amulets provides comparative information on themes and structures of the religious traditions examined. A strong emphasis is placed on the material features of the amulets and their connections to ritual purposes. The textual content, as well as other characteristics, is examined systematically, in order to establish patterns of influence and diffusion. The question of production, which includes the relationships that linked professional magicians, artists and craftsmen to their clientele, is also discussed, as well as the sacred and cultural economies involved.
