Egeria, Etheria, or Ætheria was a Western European Christian woman, widely regarded to be the author of a detailed account of a pilgrimage to the Holy Land about 381/2–386. The long letter, dubbed Peregrinatio or Itinerarium Egeriae, is addressed to a circle of women at home. Historical details it contains set the journey in the early 380s, making it the earliest of its kind. It survives in fragmentary form in a later copy—lacking a title, date and attribution.
