The poem "Ode to the West Wind" by Percy Bysshe Shelley is divided into 5 sections called cantos. The first 3 cantos describe the effects of the West Wind on leaves, clouds, and sea. The last 2 cantos feature Shelley speaking directly to the wind, asking it to lift him up and spread his thoughts to awaken the world, like the wind spreads seeds. The wind represents the power of nature and the coming of autumn and winter.
