Whatever you think about the poetry of Walt Whitman (1819–1892), indisputably he does go on. As our poetry editor has noted before, it’s hard to choose a Whitman poem for the Sun’s Poem of the Day, simply because so many of them are so long. Of course, Whitman is not alone in this. Many nineteenth-century poets did go on. Longfellow’s “The Song of Hiawatha” and “Evangeline,” for example, are not haiku.
