What are some good examples of Edgar Allan Poe's writings that would reflect on his life story? ?

I have an essay to write, which i have to choose one of poes short stories or poems and reflect ton it, by comparing his life story (being a great writer, then after his wife dies, he becomes a bum and dies) Im thinking about using Eldorado, but what are some other good ones i can use that are long enough so i can use examples from the literature?
