One of the most important British Romantic period writers and a mesmerizing conversationalist and lecturer, Coleridge authored poetry, plays, criticism, journalism, and philosophical works. His most important poetic works include Poems on Various Subjects (1796), Fears in Solitude (1798), Lyrical Ballads (with William Wordsworth, 1798), Christabel; Kubla Khan, a Vision; The Pains of Sleep (1816), and Sibylline Leaves (1817). His plays include The Fall of Robespierre (with Robert Southey 1794) and Remorse (1813). He authored the periodicals The Watchman (1796), The Friend (1809-1810), and The Statesman's Manual (1816). His Biographia Literaria (1817) is a part aesthetic, part philosophical study in the format of a literary autobiography. Specimens of the Table Talk of the late Samuel Taylor Coleridge (1835) provides a posthumous record of his conversation. A series of his lectures was published posthumously as Seven Lectures upon Shakespeare and Milton (1856).
