At ten years of age she was taken home again. After a short residence at home, she was placed at the Dominican Convent, probably the same of which De La Force gives so particular an account in his work, entitled Nouvelle Description De La France. It was founded in 1242.
I stayed, only a little while at home. The reason of my remaining so short a time was this: a nun of the Dominican Order, who belonged to a distinguished family, and was an intimate friend of my father, solicited him to place me in her Convent, of which she was Prioress. This lady had conceived a great affection for me; and she promised my father, that she would take care of me herself, and would make me lodge in her own chamber. But circumstances occurred, which prevented her from fulfilling her intentions. Various troubles arose in the Religious Community, of which she had the charge, which necessarily occupied her attention; so that she was not in a situation to take much care of me.
Her opportunities for intellectual improvement, during her residence in the Dominican Convent, where she continued during eight months, were interrupted in some degree by sickness. But with a mind of naturally enlarged capacity, and which seemed to have an instinct for knowledge, she could hardly fail to improve.
During her residence at this place, she was left more with herself than had been customary with her. But her solitary hours, secluded as she was in a great degree from objects that might have distracted her attention, were not unprofitable ones.
She remained at the Convent of the Dominicans eight months, after which she returned home.
