Treason and murder ever kept together,

As two yoke-devils sworn to either’s purpose,

Working so grossly in a natural cause,

That admiration did not whoop at them:

But thou, ’gainst all proportion, didst bring in

Wonder to wait on treason and on murder:

And whatsoever cunning fiend it was

That wrought upon thee so preposterously

Hath got the voice in hell for excellence . . .

—William Shakespeare, Henry V, Act II, Scene II
