Final answer:
The repeated lines in Robinson's villanelle create a mournful tone, conveying grief and a profound sense of loss and resignation, emphasizing the theme of finality and desolation.
Step-by-step explanation:
The villanelle, "The House on the Hill" by Edwin Arlington Robinson, utilizes the lines "They are all gone away, / There is nothing more to say" as refrains to reinforce a theme of desolation and finality. The repetition of these lines throughout the poem underpins the poem's mournful tone and underscores a profound sense of loss and resignation to the passage of time. The use of the villanelle form, with its strict pattern of repetition, amplifies the haunting and obsessive quality of the speaker's ruminations on abandonment and decay. The effect is neither joyful nor a reminder to cherish memories, but rather to convey the speaker's grief and acceptance that there is no longer anything to be done or said about the past, creating a sense of hopelessness and finality.
