Illuminata Bembo, wrote her biography in 1469. A strong local Bolognese cult of Caterina Vigri developed and she became a Beata in the 1520s but was not canonized until 1712. Literary works Catherine's best-known text is Seven Spiritual Weapons Necessary for Spiritual Warfare which she appears to have first written in 1438 and then rewritten and augmented between 1450 and 1456. Although she probably taught similar ideas, she kept the written version hidden until she neared death and then handed it to her confessor with instructions to send a copy to the Poor Clares at Ferrara. Part of this book describes at length her visions both of God and of Satan. The treatise was circulated in manuscript form through a network of Poor Clare convents. The Sette Armi Spirituali became an important part of the campaign for her canonization. It was first printed in 1475, and went through 21 later editions in the sixteenth and seventeenth centuries, including being translated into Latin, French, Portuguese, English, Spanish, and German. It, therefore, played an important role in the dissemination of late medieval vernacular mysticism in the early modern period. In addition, she wrote lauds, short religious treatises, and letters, as well as a 5000-line Latin poem called the Rosarium Metricum, the I Dodici Giardini and I Sermoni. These were discovered around 2000 and described by Cardinal Giacomo Biffi: as "now revealed in their surprising beauty. We can ascertain that she was not undeserving of her renown as a highly cultivated person. We are now in a position to meditate on a veritable monument of theology which, after the Treatise on the Seven Spiritual Weapons, is made up of distinct and autonomous parts: The Twelve Gardens, a mystical work of her youth, Rosarium, a Latin poem on the life of Jesus, and The Sermons, copies of Catherine's words to her religious sisters." Saint Catherine of Bologna had good education in drawing, writing, reading and language. Artistic works Catherine represents the rare phenomenon of a 15th-century nun–an artist whose artworks are preserved in her personal breviary. She meditated while she copied the scriptural text, adding about 1000 prayer rubrics, and drew initials with bust-portraits of saints, paying special attention to images of Clare and Francis. Besides multiple images of Christ and the infant swaddled Christ Child, she depicted other saints, including Thomas Becket, Jerome, Paul, Anthony of Padua, Mary Magdalene, and Catherine of Alexandria.
