In 1288 Agnes, despite her youth at only 20 years of age, was noted for her devotion to the Blessed Sacrament and deep life of prayer, and was elected as the abbess of the community. There she gained a reputation for performing miracles; people suffering from mental and physical ailments seemed cured by her presence. She was reported to have "multiplied loaves", creating many from a few on numerous occasions, recalling the Gospel miracle of the loaves and fishes. She herself, however, suffered severe bouts of illness which lasted long periods of time.
