“ Agnes had left him to become the spouse of Christ, he is said to have remarked: "If she had left me for a mortal man, I would have taken vengeance with the sword, but I cannot take offence because in preference to me she has chosen the King of Heaven."

She was elected abbess of the monastery, and became in this office a model of Christian virtue and religious observance for all. ”
