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)
