Itinerarium Egeriae Y2 [= Peter the Deacon's citation]; ed. R. Weber, CCSL 175:100; PL 173:1129D; trans. Wilkinson 1999, p. 94. This passage is not found in the sole surviving manuscript, which is only partially preserved, but appears in a later work by Peter the Deacon that uses Egeria as a source; see Wilkinson 1999, 4, 86. Wilkinson is confident "this is the first text to mention what became the regular Christian explanation of the pyramids" (94 n. 4); cf. Osborne 1986, p. 115.
Historia monachorum in Aegypto 18.3; ed. Preuschen 1897, 79; ed. Festugière 1971, 115; trans. Russell 1980, p. 102. There is also a Latin version by Rufinus, which includes "additions and alterations appropriate to a man who had seen the places and people for himself and regarded the experience as the most treasured of his life" (Russell 1981, 6). Rufinus seems less clear: "There is a tradition that these sites, which they call the storehouses (thesauros) of Joseph, are where Joseph is said to have stored up the grain. Others say it is the Pyramids themselves in which it is thought that the grain was collected" (PL 21:440; ed. Schulz-Flügel 1990, p. 350).
