Percy Bysshe Shelley

Percy Bysshe Shelley (/bɪʃ/ ^ⓘ BISH; 4 August 1792 – 8 July 1822) was an English writer who is considered one of the major English Romantic poets. A radical in his poetry as well as in his political and social views, Shelley did not achieve fame during his lifetime, but recognition of his achievements in poetry grew steadily following his death, and he became an important influence on subsequent generations of poets, including Robert Browning, Algernon Charles Swinburne, Thomas Hardy, and W. B. Yeats. American literary critic Harold Bloom describes him as "a superb craftsman, a lyric poet without rival, and surely one of the most advanced sceptical intellects ever to write a poem."

Shelley's reputation fluctuated during the 20th century, but since the 1960s he has achieved increasing critical acclaim for the sweeping momentum of his poetic imagery, his mastery of genres and verse forms, and the complex interplay of sceptical, idealist, and materialist ideas in his work. Among his best-known poetic works are the long poems Alastor, or The Spirit of Solitude (1816), Julian and Maddalo (1818-19), The Mask of Anarchy (1819, a political poem), Adonais (1821, a pastoral elegy for John Keats) and The Triumph of Life (1822, his last major work, unfinished); the short poems Ozymandias (1818), Ode to the West Wind (1819) and To a Skylark (1820); and the verse dramas The Cenci (1819), Prometheus Unbound (1820) and Hellas (1822).

Shelley also wrote prose fiction and a quantity of essays on political, social, and philosophical issues. Much of this poetry and prose was not published in his lifetime, or only published in expurgated form, due to the risk of prosecution for political and religious libel. From the 1820s, his poems and political and ethical writings became popular in Owenist, Chartist, and radical political circles, and later drew admirers as diverse as Karl Marx, Mahatma Gandhi, and George Bernard Shaw.

Shelley's life was marked by family crises, ill health, and a backlash against his avowed atheism, political views, and defiance of social conventions. He went into permanent self-exile in Italy in 1818 and over the next four years produced what Zachary Leader and Michael O'Neill call "some of the finest poetry of the Romantic period". His second wife, Mary Shelley, was the author of Frankenstein. He died in a boating accident in 1822 at age 29.
