What metaphors are used in And of Clay Are We Created by Isabel Allende?

From the beginning, Rolf Carlé is determined to rescue the girl, to "snatch her from death." A meyaphor of Orpheus. But although she is trapped and can barely breathe, the girl does not struggle and does not seem desperate. She seems to know that she will die and to accept her fate. Some of her attitude may come from her Roman Catholic faith, which teaches that life and death are both gifts of God. Faith does not seem important to Carlé, who never mentions God or religion in his long talks with the girl, and he believes that he can defeat death.
