Left a widow in 1492, she busied herself in the administration of her duchy and the education of her children. When she was relieved of the duties imposed upon her by her position, she decided to renounce the world and retired to Mortagne, to a monastery of religious women who followed the rule of Saint Elizabeth. Later, having brought with her to Argentan some of these nuns, she founded there another monastery which she placed, with the authorization of the pope, under the rule of
Saint Clare, modified by the Minor Observants. She herself took the religious habit in this house and made her vows on 11 October 1520. On 2 November 1521, after having lived an austere life for a year, she died in her modest cell, at the age of fifty-eight. Her body, preserved in the monastery of the Poor Clares, and when that monastery was suppressed, was transferred to the church of Saint Germain d'Argentan. In 1793, during the
French Revolution, it was profaned and thrown into the common burial place. ==Legacy==
