The form on the poem is a villanelle, with a rhyme scheme alternating “night” and “day.” A villanelle is a French poetic form that originally served as a vehicle for pastoral, simple, and light verse. A villanelle is a poem of nineteen lines that begins with five stanzas of three lines and a final quatrain of set pattern. The fact that Thomas use’s this form for the subject of death enhances the irony of beseeching a dying person to rage.

The close of the stanza is another command. This time, instead of a negative command “do not” Dylan writes a positive imperative statement “(you) rage.” The next three stanzas discuss how three different types of men might feel about their death when it comes. The beginning of the second stanza is
