Samuel Taylor Coleridge (1772-1834) was an English poet, critic, and philosopher who was, along with his friend William Wordsworth, one of the founders of the Romantic Movement in England and one of the Lake Poets. He is probably best known for his poems The Rime of the Ancient Mariner and Kubla Khan, as well as his major prose work Biographia Literaria.
Sometimes I actually prefer Coleridge's literary criticism to his poetry - although I enjoy both. This was really interesting, and it's pretty cool to see how Coleridge's thoughts on Shakespeare laid the foundation for our perception of the man and his works.
