The Dove
The author figuratively uses the dove to symbolize peace, beauty, and innocence. The dove’s image is predominant throughout the text. However, the symbolic meaning of the dove starts becoming eminent when the reader learns more about Milly. The dove symbolizes Milly's tranquility and love. Unlike other characters, Milly is not violent and does not get involved in any manipulative activities. Similarly, the dove symbolizes Milly's beauty and innocence. For instance, Kate Croy complements Milly by telling her that she is a dove, meaning that she is harmless.
Water
The author uses water to symbolize re-enactment. In the text, characters swim in a flowing river to renew their thinking and refresh their bodies. Consequently, the water in the river symbolizes restoration, and every character needs to refresh at some point to continue doing things correctly. The author compares swimming in the river to renewed consciousness and experiences that make life meaningful.
The symbolism of death
Death is symbolized by Milly when she turns her face to the wall. For instance, Susan tells Merton, "Milly has turned her face to the wall," to notify him that Milly's situation is worsening. Consequently, Susan uses a Biblical quote to describe the end of life. According to Susan, Milly will die slowly but happily only if Merton confesses his love for her.
