How does Edith Wharton use imagery in Roman Fever?

Wharton makes use of a number of symbols and images to reinforce the emotions of the story. The ruins that the two women are gazing at of the Palatine, the Forum, and the Colosseum symbolize the ruins of these women's perceptions of themselves and each other. Mrs. Ansley calmly knits, which would seem to be the staid activity of a middle-aged woman, but what she is knitting is described as "a twist of crimson silk." Her knitting can be said to represent the passionate and more frivolous side of her nature. Also, the women's actions can be viewed symbolically, to indicate their feelings toward the conversation and each other. As soon as Mrs. Slade starts to talk about their shared past, Mrs. Ansley lifts her knitting "a little closer to her eyes," thus shielding herself and her reactions from Mrs. Slade. However, when Mrs. Slade learns that Mrs. Ansley did meet Delphin at the Colosseum, it is Mrs. Slade who must cover her face and hide her deepest emotions. In fact, by the end of the story, the power structure has changed, as shown by Mrs. Ansley's actions. After revealing the truth about Barbara's father, she "began to move ahead of Mrs. Slade toward the stairway."
