MENENIUS: His nature is too noble for the world.
He would not flatter Neptune for his trident
Or Jove for ‘s power to thunder. His heart’s his mouth;
What his breast forges, that his tongue must vent,
And, being angry, does forget that ever
He heard the name of death.William Shakespeare (1564-1616) English dramatist and poet
Coriolanus, Act 3, sc. 1, l. 326ff (3.1.326-331) (c. 1608)
