In the Desert, by Stephen Crane

In the desert
I saw a creature, naked, bestial,
Who, squatting upon the ground,
Held his heart in his hands,
And ate of it.
I said, "Is it good, friend?"
"It is bitter – bitter", he answered,
"But I like it
Because it is bitter,
And because it is my heart."

- Stephen Crane, 'In The Desert'
