Mattie’s character constitutes the hinge on which the plot of Ethan Frome turns. All of the story’s events are set in motion by her presence in the Frome household. Yet we glimpse Mattie, as we glimpse Zeena, only through Ethan’s eyes, and his perception of her is skewed by his passion. With her grace, beauty, and vitality, she obviously embodies everything that he feels Zeena has denied him, and so becomes the focus of his aborted rebellion against his unhappy life. Mattie is distinguished by little other than the red decoration she wears, which symbolizes both passion and transgression.
