In 1731, he completed a series of moral works which made him recognised as a great and original genius. This was "A Harlot's Progress". It was first done as paintings, which are now lost. Then the series was published as engravings. In the six scenes, the fate of a country girl who became a prostitute in town is traced out. At the start, the girl meets a bawd, a woman who persuades her to take up prostitution. At her shameful end, the girl dies of venereal disease and there follows a merciless funeral ceremony. The engraving show vivid scenes of drunken and loose behaviour. The series was an immediate success.
