John Bunyan's The Pilgrim's Progress (1678) follows the precepts of Puritanism both for its style and content. The allegorical text of a soul's journey to spiritual salvation and rejection of material temptations is told by Bunyan in that plain style that Puritan thinkers said should caracterise literature. The message should be made easily comprehensible for the masses and this is certainly the case with the book whose main purpose is to instruct and give a perfect example of Puritan life. Thanks to its accessibility, The Pilgrim's Progress was one of the most popular books in English-speaking countries until the nineteenth century. On the level of content, The Pilgrim's Progress shows how Puritan beliefs inform every aspect of its main character's life, making him an elected soul for spiritual salvation.
