"Ode to the West Wind" is an ode, written by Percy Bysshe Shelley in 1819 in Cascine wood near Florence, Italy. It was originally published in 1820 by Charles Ollier 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. The poem allegorises the role of the poet as the voice of change and revolution. At the time of composing this poem, Shelley without doubt had the Peterloo Massacre of August 1819 in mind. His other poems written at the same time—"The Masque of Anarchy", Prometheus Unbound, and "England in 1819"—take up these same themes of political change, revolution, and role of the poet.
