‘’O Captain! My Captain” is an extended metaphor, as Whitman symbolically connects the death of the sea captain to the assassination of Abraham Lincoln on April 14, 1865, just five days after the end of the Civil War. Looking at the poem through the lens of the extended metaphor, explain what Whitman intends each of the following items to represent: a. “our fearful trip” (line 1) c. “the vessel” (line 4) b. “the prize” (line 2) d. “the swaying mass” (line 12)
