If thine eye offend thee, pluck it out

If your tired unspeaking head
Rivet the dark with linear sight,
Crazed by a warlock with his curse
Dreamed up in some loquacious bed,
And if the stage-dark head rehearse
The fifth act of the closing night,

Why, cut it off, piece after piece,
And throw the tough cortex away,
And when you've marvelled on the wars
That wove their interior smoke its way,
Tear out the close vermiculate crease
Where death crawled angrily at bay.

Allen Tate
