He was born in Sussex in 1792, studief at Eton and met William Godwin and Byron. Between 1820 and 1821 he wrote the lyrics 'ode to the west wind', 'to a skylark', 'the cloud' and the dramatic poem 'Prometheus unbound'(in this last work the poet is compared with Prometheus: the poet has the fire of his ideas that conditions the poem). He was a radical who rebelled against all forms of cruelty, authority and tyranny. He believed in the essence of a god, a spiritual divinity for him. He is an outcast and a prophet: he takes the umanity to a world of love and liberty. He is the figure of the wandering Jew because he is insatisfied by the reality. For him the world is full of liberty, love and beauty and the nature is the manifestation of the god, is a refugee in times of social injustices and is instrumental to the poet because he uses the imagines of the nature for build a symbolic cosmos. He distinguishes between reason (faculty of analysis and calculation) and imagination (faculty of wholeness that produces a vision of beauty and truth). For him poetry is the expression of the imagination and is equated with love. In 1822 he began his last poem 'the triumph of life' and he was caught in a storm while he was sailing in his boat, the Ariel.
Ode to the west wind
It is an ode (lyric enthusiastic in tone, full of archaism, invocations and personifications) written in autumn near Florence in arcaic language where there is an invocation to the wind. This poem tells the story of a tempest of hail and rain which influenced the Cisalpine regions, in which the vegetation is influenced by the winds and changes is aspect.
