Catherine of Bologna [Caterina de' Vigri] (8 September 1413 – 9 March 1463) was an Italian Poor Clare, writer, teacher, mystic, artist, and saint. The patron saint of artists and against temptations, Catherine de' Vigri was venerated for nearly three centuries in her native Bologna before being formally canonized in 1712 by Pope Clement XI. Her feast day is 9 March. Life Catherine came from an upper-class family, the daughter of Benvenuta Mammolini of Bologna and Giovanni Vigri, a Ferrarese notary who worked for Niccolò III d'Este, Marquis of Ferrara. She was raised at Niccolo III's court as a lady-in-waiting to his wife Parisina Malatesta (d. 1425) and became lifelong friends with his natural daughter Margherita d'Este (d. 1478). During this time, she received some education in reading, writing, music, playing the viola, and had access to illuminated manuscripts in the d'Este Court library. In 1426, after Niccolo III's execution of Parisina d'Este for infidelity, Catherine left court and joined a lay community of beguines living a semi-religious life and following the Augustinian rule. The women were divided over whether instead to adhere to the Franciscan rule, which eventually happened. In 1431 the beguine house was converted into the Observant Poor Clare convent of Corpus Domini, which grew from 12 women in 1431 to 144 women by the end of the century. Catherine lived at Corpus Domini, Ferrara most of her life from 1431 to 1456, serving as Mistress of Novices. She was a model of piety and reported experiencing miracles and several visions of Christ, the Virgin Mary, Thomas Becket, and Joseph, as well as future events, such as the fall of Constantinople in 1453. She wrote a number of religious treatises, lauds, sermons, and copied and illustrated her own breviary (see below). In 1455 the Franciscans and the governors of Bologna requested that she become abbess of a new convent, which was to be established under the name of Corpus Domini in Bologna. She left Ferrara in July 1456 with 12 sisters to start the new community and remained abbess there until her death on 9 March 1463. Catherine was buried in the convent graveyard, but after eighteen days, a sweet smell emanated from the grave and the incorrupt body was exhumed. It was eventually relocated to a chapel where it remains on display, dressed in her religious habit, seated upright behind glass. A contemporary Poor Clare, Sister
