Why did Mary cassett use mirrors in her paintings?

Mary Cassatt used mirrors in her paintings to explore themes of reflection, intimacy, and the complexity of women's roles in society. Mirrors allowed her to create layered compositions that captured both the subject and the act of observing, emphasizing the connection between the viewer and the depicted moment. This technique also highlighted the domestic sphere, often portraying mothers and children, while inviting contemplation on self-perception and identity. By incorporating mirrors, Cassatt added depth and narrative to her intimate scenes.
