The middle part of Egeria's writing survived and was copied in the
Codex Aretinus, which was written at
Monte Cassino in the 11th century, while the beginning and end are lost. This
Codex Aretinus was discovered in 1884 by the Italian scholar
Gian Francesco Gamurrini, in a monastic library in
Arezzo. Gamurrini published the Latin text and theorised the author was
Sylvia of Aquitaine. In 1903, Marius Férotin claimed the author is one Aetheria or Egeria, known from a letter written by the seventh century
Galician monk
Valerio of Bierzo. He dated her pilgrimage to about 381–384, during the reign of
Theodosius I. Férotin believed she was from
Gallaecia, but in 1909 Karl Meister disputed Férotin's theory about the date of Egeria's pilgrimage and her identity. Meister argues that her language shows no evidence of
Iberian Romance but rather suggests that she may have been from one of the well-known religious houses of sixth century
Gallia Narbonensis; according to this theory, her pilgrimage took place in the first half of the reign of
Justinian I (
r. 527–565). It is through Valerio's letter that we first see the name Aetheria or Egeria, and have much of the biographical information. He praises Egeria and identifies her as a nun, perhaps because she addresses her account to her "sorores" (Latin for "sisters") at home. However, others (including Hagith Sivan, 1988) have pointed out that during Egeria's time it was common to address fellow lay Christians as "sisters" and "brothers". It is possible that Egeria used the term to address her Christian acquaintances. Valerio may also have believed her to be a nun because she went on such a pilgrimage, although lay women of the time are known to have engaged in such
religious tourism. Egeria's ability to make a long and expensive journey by herself, her numerous acquaintances and attentive guides in the places she visited, and her education indicate her middle or upper class wealthy background. In his letter to Egeria, Valerio mentioned the shores of the "Western sea" or "Ocean" from which Egeria was sprung, which suggests he was writing about a person travelling from the Roman
Gallaecia, but Meister believes that her reference to the river
Rhone supports his theory of Gaulish origin. ==
