In this play about the Deadly Sin of Lust, Saint Francis, almost blind and toothless and nearing the end of his life, revisits Assisi, where he encounters Pica, a young girl with the same name as his mother; Mother Clara of Saint Damian's Convent; and Mona Lucrezia (now a mad woman) with whom he had a love affair when he was a wild, willful young man known as Francis the Frenchman, and she was a young married woman. Saint Francis still seeks expiation for the "load of sin" with which he has offended God. The play poses questions about the true meaning of love-and, as Wilder wrote, about "the ideas of the Erotic as Destroyer and the Erotic as Creative."
