The skin of the coward changes color all the time, he can't get a grip on himself, he can't sit still, he squats and rocks, shifting his weight from foot to foot, his heart racing, pounding inside the fellow's ribs, his teeth chattering. He dreads some grisly death. But the skin of a brave soldier never blanches. He's all control. Tense but no great fear.
HomerZeus most glorious and most great, Thundercloud, throned in the heavens! Let not the sun go down and the darkness come, until I cast down headlong the citadel of Priam in flames, and burn his gates with blazing fire, and tear to rags the shirt upon Hectors breast! May many of his men fall about him prone in the dust and bite the earth!
Homer
