Life and Ascetic Struggle
According to the synaxarion, Anna was the daughter of a deacon who served at the church of Blachernae in Constantinople. After she was widowed, she set aside her former life and gave herself to monastic discipline. To enter and remain within a male monastic community, she dressed in men's clothing and took the name Euthymianus.
Together with her son John, she pursued the ascetic life in a monastic community situated in the Bithynian region near Mount Olympus, a major center of Byzantine monasticism. The two shared this concealed manner of life until Anna's death in Constantinople in 826.
