I love A. E. Housman. Ezra Pound, Thomas Hardy (talking of depressing

), Robert Frost, Emily Dickinson, Philip Larkin, T. S. Eliot, Gerard Manley Hopkins, John Donne...and many others.
Poe is great, too. My favorites tend to be the early-mid 20th-century poets, though. The ideas in their poems are so profoundly sad that they make my bones ache, but I can't stop reading them. D:

And there's so much there to analyze, too, if you're into that sort of thing (I am).
