Monastic life and works
In her monastic life Anthusa is described as taking part in manual labor, serving the other nuns at meals, and maintaining a strict discipline. Her care extended beyond the cloister to the poor, to orphans, and to widows, and the Omonia monastery she founded carried in its name (rendered as Concord or Charity) the charitable character ascribed to her work.
The narratives of her life set her piety against the iconoclast policy of her father Constantine V. Where the emperor is remembered for his hostility to the holy icons, his daughter is remembered for venerating them and for embracing the monastic life that the iconoclast establishment often opposed.
