(9) Mount Everest
As flowing as its formal structure is, The Rape of the Lock is full of archaic language (the 18th century was a while ago, yo) and references to Classical literature that most 21st-century students probably have little or no experience with (Shmoop readers excepted, of course).
That said, getting through this poem will help you learn not only a whole heck of a lot about 18th century culture, about writing narrative poetry in a strict form, about the ways society can warp the people within it, and about the complex ways that satire can work. It will also, if you track down those references, help you learn more about Classical literature than you knew before. A win-win-win situation, if you ask us.
