Romantic Poetry
In 1784, James Thomson's book was published, The Poetical Works of James Thomson. Thomson was one of the many revered poets of the Romantic era that led to inspiring the character 'Marianne' in Austen's Sense and Sensibility. William Cowper, another Romantic poet Sense and Sensibility's 'Marianne is said to have read, also had his book published, The Task with Tirocinium, and Selections from the Minor Poems, in 1784.
