fabulous literature

what languages would you recommend being acquainted with if you were a lover of literature, poetry prose etc? and really wanted to try to read/translate these in the original language, as best as you could? in addition what are some novels you would recommend that are affiliated with these languages?

i've been really drawn to portuguese, because of authors like Saramago and Coelho. and of course Russian, with its famed authors such as Tolstoy and Nabokov. thats really the extent of my knowledge though, so any suggestions would be wonderful! thanks =)
