Pope's The Rape of the Lock is a mock epic. That is, it's a poem written as an epic that satirizes ideas about propriety, the behavior of the aristocracy, the importance of beauty, and the outrage that the offense causes. This poem's language may be a bit obtuse, but the ideas are over the top, and the effective satire has made people smirk for generations. Poems like The Rape of the Lock are admired for their commentary on contemporary values as much as for the entertainment they provide.
