24th December is the day the Eastern Orthodox Church remembers St Eugenia / Eugenios of Alexandria, another of the group of female saints in the early church who dressed as men to be admitted to all-male monasteries.
Holy Virgin and Martyr Eugenia and her companions (~190)
“This Martyr was the daughter of most distinguished and noble parents named Philip and Claudia. Philip, a Prefect of Rome, moved to Alexandria with his family. In Alexandria, Eugenia had the occasion to learn the Christian Faith, in particular when she encountered the Epistles of Saint Paul, the reading of which filled her with compunction and showed her clearly the vanity of the world. Secretly taking two of her servants, Protas and Hyacinth, she departed from Alexandria by night. Disguised as a man, she called herself Eugene [Eugenios -ed.] while pretending to be a eunuch, and departed with her servants and took up the monastic life in a monastery of men. Her parents mourned for her, but could not find her. After Saint Eugenia had laboured for some time in the monastic life, a certain woman named Melanthia, thinking Eugene to be a monk, conceived lust and constrained Eugenia to comply with her desire; when Eugenia refused, Melanthia slandered Eugenia to the Prefect as having done insult to her honour. Eugenia was brought before the Prefect, her own father Philip, and revealed to him both that she was innocent of the accusations, and that she was his own daughter. Through this, Philip became a Christian; he was afterwards beheaded at Alexandria. Eugenia was taken back to Rome with Protas and Hyacinth. All three of them ended their life in martyrdom in the years of Commodus, who reigned from 180 to 192.” (Great Horologion)
