Answer
After the commercial and critical success of "The Scarlet Letter," Nathaniel Hawthorne went on to publish three more novels during his lifetime. These were "The House of the Seven Gables" in 1851, "The Blithedale Romance" in 1852, and "The Marble Faun" in 1860. Each of these works further showcased Hawthorne's mastery of psychological depth, allegorical storytelling, and historical context, solidifying his position as one of America's greatest literary figures.
