According to Wikipedia: 'The Fortunes and Misfortunes of the Famous Moll Flanders (commonly known simply as Moll Flanders) is a novel written by Daniel Defoe in 1722, after his work as a journalist and pamphleteer.’ 'Memoirs of a Woman of Pleasure (popularly known as Fanny Hill) is an erotic novel by John Cleland first published in England in 1748. Written while the author was in debtor’s prison in London, [1][2] it is considered 'the first original English prose pornography, and the first pornography to use the form of the novel.’
