Saint Catherine of Genoa (Caterina Fieschi Adorno, born Genoa 1447 – 15 September 1510) is an Italian Roman Catholic saint and mystic, admired for her work among the sick and the poor. She was a member of the Fieschi family, and spent most of her life and her means serving the sick, especially during the plague which ravaged Genoa in 1497 and 1501. She died in that city in 1510. Her fame outside her native city is connected with the publication in 1551 of the book known in English as the Life and Doctrine of Saint Catherine of Genoa.
In 1551, 41 years after her death, a book about her life and teaching was published, entitled Libro de la vita mirabile et dottrina santa de la Beata Caterinetta de Genoa. This is the source of her "Dialogues on the Soul and the Body" and her "Treatise on Purgatory".
This edition of Treatise on Purgatory is specially formatted with a Table of Contents.
