Sarah Iles Johnston has innovated in the study of myth, ritual, and belief, and her scholarship in these areas informs the contributions to this volume, each of which uses Johnston to innovate in turn. The capacity of Johnston's work to underpin scholarship on phenomena from the ancient Mediterranean to the present day--from Isis charms in Christian Egypt to American goddess worship; from healing in the Epidaurian iamata to the medicine of Linda Hogan's Indios; from the believability of a Syriac ghost story to that of theurgic ritual--illustrates Johnston's impact and the vibrant state of work on myth, ritual, and belief.
