Sweeney, who has written several popular histories of religious movements and figures, presents a dual biography conveying the intense religious spirit of the medieval world while describing a platonic friendship of two kindred souls. Francis, of course, had an immense and enduring impact on Christianity with his devotion to compassion, simplicity, and the preaching of the Gospels. Clare, also from Assisi, was 12 years younger than Francis and deeply moved by his preaching. She consciously rejected the affectations of her upper-class friends and family, disdaining fine clothes and other ostentatious displays of wealth. Like Francis, she strove to imitate the life of Jesus by living a life of poverty combined with service to humanity. Sweeney's story is reverent and inspiring, and it also sheds light on many aspects of medieval society that are often ignored in religious tracts, including the corruption of the clergy, schisms within the early Franciscan movement, and the role of women in religious reform movements. This work will be particularly appealing to religious laypeople, but general readers can also find much of value here.
