Wharton's use of structure contributes to the depiction of Ethan's tragedy. The prologue and the epilogue, which take place some twenty years after the events of the main story, are written in first person from The Narrator's point of view. Structurally, these portions of the novel constitute a "frame" around the story itself; however, this frame is more than a decoration. The prologue not only establishes the nature of theme and action, but also begins the characterization of Zeena and Ethan Frome. It also sets the important patterns of imagery and symbolism and starts a tone of omniscient narration throughout the body of the novel. Ethan is the only character who is thoroughly explored.
Wharton's attention to minor details and her use of structure to relay Ethan's complicated and tragic life story to readers enables her to portray her characters as victims of the rules of society.
