St. Rosa of Viterbo, Virgin
[Of the Third Order of St. Francis.] 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 Waddings 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.
