What is your favorite poem?

W.B. Yeats' "He Wishes for the cloths of heaven"

"...But I being a poor man have only my dreams
I take my dreams and spread them beneath your feet
tread softly
Because you tread on my dreams..."

love that part
 
My favorite poem is probably "The Hollow Men" by T.S. Eliot, but you probably have to read Conrad's "Heart Of Darkness" to fully understand it. I also like the short little sonnet by John Keats called "When I Have Fears That I May Cease To Be." Neat stuff.

I want to read Dante's Inferno one of these days too.
 
I'm not saying this only because this is an SX forum. DWOT and all of the stuff from V kill everything else. Also, Tennyson's Charge of the Light Brigade.
