How did a thirteenth-century Italian friar become one of the best-loved saints in America? Around the nation today, St. Francis of Assisi is embraced as the patron saint of animals, beneficently presiding over hundreds of Blessing of the Animals services on October 4, St. Francis's Catholic feast day. Not only Catholics, however, but Protestants and other Christians, Hindus, Buddhists, Jews, and nonreligious Americans commonly name him as one of their favorite spiritual figures. Drawing on a dazzling array of art, music, drama, film, hymns, and prayers, Patricia Appelbaum explains what happened to make St. Francis so familiar and meaningful to so many Americans.
