This open-access volume is the first to explore systematically and comprehensively the concept and category of horror in antiquity. The contributors retrieve the ancient grammar of horror by paying equal attention to its affective and cognitive dimensions, and by looking at it as an embodied, enactive and full-rounded existential experience. They explore how horrifying experiences in antiquity are construed as embodied events while being conceptually rooted in cultural frameworks. They also showcase the ways in which the body itself can turn into a source of deep horror, be it in literary or medical texts and traditions in the Greek and Roman world, from the classical period to late antiquity. While maintaining a firm awareness of the fact that horror , a largely post-Romantic concept, is not unproblematic when applied to Graeco-Roman antiquity, this collection of studies shows that our Graeco-Roman past can shed substantial light on the ways in which the horrific is understood today, as a category of art but also of life itself.
