For other uses, see Leaves of Grass (disambiguation). Leaves of Grass is a poetry collection by the American poet Walt Whitman (1819â1892). Though the first edition was published in 1855, Whitman spent most of his professional life writing and re-writing Leaves of Grass, revising it multiple times until his death. This resulted in vastly different editions over four decadesâthe first a small book of twelve poems and the last a compilation of over 400.
How Walt Whitman Changed The World of Poetry & What You Can Learn From It. In the early 19th century, poetry rhymed. Period. End of story. Free verse didnât exist yet, and anything that didnât descend from a long line of European traditions dictating style, content, and form was quickly dismissed as commonerâs gobbly-gook. It might be called sentimental, perhaps moving, but not poetic. Walt Whitman changed all that. The ideal American poet, according to Whitman, did not elevate himself above the common man. He didnât hold fast to tradition for traditionâs sake. And, above all, he did not identify with Europe, itâs land, people or society.
