A folkloric and anthropological study examines belief in the evil eye among Gaelic-speaking Highland communities, attributing it to natural jealousy and covetousness while noting how Christian teaching has shaped its expression. The author collects oral testimony and Gaelic examples that describe symptoms, social repercussions, and effects attributed to the glance, and provides extensive documentation of charms, preventive measures, diagnostic rites, cures, and theories of transmission alongside discussion of local variants and practice.
