A Harlot's Progress (also known as The Harlot's Progress) is a series of six paintings (1731, now destroyed) and engravings (1732) by the English artist William Hogarth. The series shows the story of a young woman, M. (Moll or Mary) Hackabout, who arrives in London from the country and becomes a prostitute. The series was developed from the third image. After painting a prostitute in her boudoir in a garret on Drury Lane, Hogarth struck upon the idea of creating scenes from her earlier and later life. The title and allegory are reminiscent of John Bunyan's Pilgrim's Progress.
