Tradition and Sources
Apollinaria belongs to a group of saints in the Eastern tradition — among them Saints Pelagia, Eugenia, and Marina (Marinos) — whose lives recount a noblewoman or virgin living undetected as a monk in a men's monastery. Her surviving life identifies her ascetic home as the desert of Scetis (Wadi El Natrun in the Nitrian Desert) and places her under the direction of an abba named Macarius; the sources differ as to whether this is Macarius of Egypt (the Great) or Macarius of Alexandria. The narrative is preserved in the synaxaria and was given literary form by later hagiographers, and modern scholarship treats the story as largely legendary, the date of her death being variously given as 420 or 470.
She is honored in the Eastern Orthodox Church on January 5 and, as a saint of the undivided Church, in the Roman Catholic Church on January 4.
