[of the Third Order of Saint Francis] From her childhood she addicted herself entirely to the practice of mortification and assiduous prayer; she was favoured with the gift of miracles, and an extraordinary talent of converting the most hardened sinners. She professed the third rule of Saint Francis, living always in the house of her father in Viterbo, where she died in 1261.
She was refused admittance in the Franciscan nunnery in Viterbo; therefore led a solitary life in a cottage adjoining, in the most austere penitential practices, and in assiduous contemplation and prayer. She died about the year 1252. Her body is shown enshrined in the church of this nunnery entirely incorrupt; her face appears full of flesh, and as if the corpse was just dead. She is honoured on the 6th of March, the day of her death, and on the 4th of September, the day of her translation. Her two lives are not in all parts authentic. See Wadding’s Annals of the Order, ad an. 1252, n. 17, and Suysken, the Bollandist, on her two lives, and the Acts of her canonization, t. 2, Sept. p. 414.
