Galway Kinnell, from The Book of Nightmares:

The Hen Flower
The Shoes of Wandering
Dear Stranger Extant in Memory by the Blue Juniata

The Dead Shall Be Raised Incorruptible
Little SleepsHead Sprouting Hair in the Moonlight
The Call Across the Valley of NotKnowing
The Path Among the Stones
Lastness
