Saint Hilarion, Schemamonk of Kiev Caves, a strict ascetic, was a disciple and co-ascetic with Saint Theodosius (May 3). Imitating the example of his teacher, Saint Hilarion prayed to God with tears day and night, while observing a strict fast. His contemporaries knew him as a chronicler, who toiled over the copying of books in the cell of Saint Theodosius. During this time his teacher chanted Psalms and spun wool. Saint Hilarion lived an ascetic life during the eleventh century. His memory is also celebrated on August 28 and on the second Sunday of Great Lent.
