Rick Barot’s poem “The Wooden Overcoat [3],” published in the April 2012 issue of Poetry, begins: “It turns out there’s a difference between a detail / and an image.” Barot develops this train of thought and proceeds to engage in differentiating between the two, positing that a dandelion on the sidewalk is “mere detail,” but “the dandelion inked on a friend’s bicep / is an image because it moves when her body does.” Write a poem that sets up an argument in the first sentence and then proceed to test it through rhetorical devices and concrete imagery. How can you use a poem to prove a thesis?
