Percy Bysshe Shelley (1792-1822) was an English Romantic poet who had unorthodox views for his time including atheism, free love, and vegetarianism. He was expelled from Oxford for publishing an atheist pamphlet. Some of his most famous works include the poems Ozymandias, Prometheus Unbound, and Queen Mab as well as the essays A Defence of Poetry and The Necessity of Atheism. Though he died young by drowning, Shelley is considered one of the major English Romantic poets and his works often dealt with themes of political and intellectual freedom.
