Please help compare the Mona Lisa to a piece of Literature or Song?

I am doing an essay about Leonardo Da Vinci and I know very little about art and the teacher told us to compare a painting to a poem, story, or song. I am doing the Mona Lisa. Please name a poem or song that compares to it and please help explain how they compare to each other. I did the rest of the essay by myself, 4 pages, and this is the last thing I need an I'm really stuck please help
