The majority of Evagrius's extant letters survive in a corpos of 62 letters of various lengths, all providing spiritual counsel to various figures such as Rufinus, St. Melania the Elder, St. Gregory Nazianzus, Bp. John of Jerusalem. These survive entirely in Syriac, with fragmentary survival in Greek. Some letters may actually be extracts that were, for one reason or another, included in his letters. The Armenian translation of the corpus is restricted to thirty letters, and is framed as if a correspondence between Evagrius and Melania. For letters not included in this corpus, see CPG 2438, 2439; cover letters to other treatises, e.g., CPG 2430, 2434.
