“Oliver Twist is notable for its unromantic portrayal by Dickens of criminals and their sordid lives, as well as for exposing the cruel treatment of the many orphans in London in the mid--19th century.The alternate title, The Parish Boy's Progress, alludes to Bunyan's The Pilgrim's Progress, as well as the 18th-century caricature series by William Hogarth, A Rake's Progress and A Harlot's Progress.”
