Luis Monroy. The Last Moments of Atala, 1871.
Atala tells of the tragic love story of Chactas, a Natchez Indian and Atala the half-caste Christian daughter of Simagan, the chief of the Muscogees, an enemy Indian tribe, who had captured and sentenced Chactas to death. Atala eventually frees him from captivity and they run away together. They are helped by Père Aubry, a Christian missionary and hermit, who takes them to his cave and gives them refuge.
Atala falls in love with Chactas, but cannot marry him as she has taken a vow of chastity. In despair she takes poison. Père Aubry assumes that she is merely ill, but in the presence of Chactas she reveals what she has done, and Chactas is filled with anger until the missionary tells them that in fact Christianity permits the renunciation of vows. They tend her, but she dies.
