Document 2: Ode to the West Wind: "Ode to the West Wind" is an ode, written by Percy Bysshe Shelley in 1819 near Florence, Italy. It was originally published in 1820 by Charles in London as part of the collection "Prometheus Unbound, A Lyrical Drama in Four Acts, With Other Poems". Perhaps more than anything else, Shelley wanted his message of reform and revolution spread, and the wind becomes the trope for spreading the word of change through the poet-prophet figure. Some also believe that the poem was written in response to the loss of his son, William (born to Mary Shelley) in 1819. The ensuing pain influenced Shelley.
