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: having painted 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 rich allegory are reminiscent of John Bunyan's Pilgrim's Progress.
In the first scene, an old woman praises her beauty and suggests a profitable occupation, procuring her for the gentleman shown towards the back of the image. She is a mistress with two lovers in the second, has become a common prostitute on the point of being arrested in the third, and is beating hemp in Bridewell Prison in the fourth. By the fifth, she is dying from venereal disease, and she is dead aged only 23 in the last.
The protagonist "M. Hackabout" (see Plate 1, Plate 3, and the coffin-lid in Plate 6, which reads: "M. Hackabout Died Sept 2d 1731 Aged 23") is either named after the heroine of Moll Flanders and Kate Hackabout or ironically after the Blessed Virgin Mary. Kate was a notorious prostitute and the sister of highwayman Francis Hackabout: he was hanged on 17 April 1730; she was convicted of keeping a disorderly house in August the same year, having been arrested by Westminster magistrate Sir John Gonson.
The series of paintings proved to be very popular and Hogarth used his experience as an apprentice to a silversmith to create engravings of the images, selling a "limited edition" of 1,240 sets of six prints to subscribers for a Guinea. Pirate copies of the engravings were soon in circulation, and Hogarth procured a 1735 Act of Parliament (8 Geo. II. cap. 13) to prohibit the practice. Soon after, Hogarth published his second series of satirical and moralistic images, A Rake's Progress, followed some years later by Marriage à-la-mode.
