The studies in this book derive from an international workshop held in Budapest in 2012 on magical gems: precious stone amulets engraved with inscriptions, images and magical signs, which represent the most sophisticated amulet type of the Roman Imperial Period. With contributors from a number of scholarly disciplines (classical archaeology, classical philology, Egyptology, Jewish studies, history of religions), the book provides a comprehensive overview of its subject, highlighting the many perspectives from which it can be studied, and bringing this long neglected object group on the wider horizons of classical research.
