Caius Marcius Coriolanus

Albeit Marcius himself; who was neither daunted nor humbled, but in mien, port, and countenance fully composed, seemed the only man among all the distressed patricians who was not touched by his evil plight. And this was not due to calculation, or gentleness, or to a calm endurance of his fate, but he was stirred by rage and deep resentment, and this, although the many know it not, is pain. For when pain is transmuted into anger, it is consumed, as it were, by its flames, and casts off its own humility and sloth.

Wherefore the angry man makes a show of activity, as he who has a fever is hot, his spirit being, so to speak, afflicted with throbbing, distention, and inflation. And that such was his condition, Marcius showed right quickly by his conduct.
