Percy Bysshe Shelley (1792 - 1822) was one of the major English Romantic poets, and is regarded by some as among the finest lyric, as well as epic, poets in the English language. A radical in his poetry as well as in his political and social views, Shelley did not see fame during his lifetime, but recognition for his poetry grew steadily following his death. Shelley was a key member of a close circle of visionary poets and writers that included Lord Byron; Leigh Hunt; Thomas Love Peacock; and his own second wife, Mary Shelley, the author of Frankenstein. Shelley is perhaps best known for such classic poems as Ozymandias, Ode to the West Wind, To a Skylark, Music, When Soft Voices Die, The Cloud and The Masque of Anarchy. His other major works include a groundbreaking verse drama The Cenci (1819) and long, visionary poems such as Queen Mab (later reworked as The Daemon of the World), Alastor, The Revolt of Islam, Adonais, Prometheus Unbound (1820)-widely considered to be his masterpiece-and his final, unfinished work The Triumph of Life (1822)."
