Egeria, Etheria or Aetheria was a woman, widely regarded to be the author of a detailed account of a pilgrimage to the Holy Land. The long letter, dubbed Peregrinatio (pilgrimage) 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 the kind. It survives in fragmentary form in a later copy – lacking any title, date and attribution.
