The Pilgrim's Progress tells the story of Christian's journey from his home to the Celestial City as an allegory. In the story, Christian and his companion Faithful encounter Vanity Fair, a town representing the sinful world. Vanity Fair is depicted as a bustling marketplace selling all manner of worldly goods and vices. Christian and Faithful stand out from the crowd due to their plain clothing and disinterest in the wares for sale. Their behavior arouses hostility from residents of Vanity Fair, leading to Faithful being put on trial and condemned as a heretic. The allegory uses Vanity Fair to represent the difficulty pilgrims face distinguishing themselves from worldly attractions on their journey to salvation.
