Book 11
1.102
There is another gesture not unlike the preceding, in which the remaining three fingers are folded: it is much employed by the Greeks both for the left hand and the right, in rounding off their enthymemes, Rhetorical or incomplete syllogisms. But see V. x. 2. xiv. 1 detail by detail. A gentle movement of the hand expresses promise or assent, a more violent movement suggests exhortation or sometimes praise. There is also that familiar gesture by which we drive home our words, consisting in the rapid opening and shutting of the hand: but this is a common rather than an artistic gesture.
1.103
Again, there is the somewhat unusual gesture in which the hand is hollowed and raised well above the shoulder with a motion suggestive of exhortation. The tremulous motion now generally adopted by foreign schools is, however, fit only for the stage. I do not know why some persons disapprove of the movement of the fingers, with their tops converging, towards the mouth. For we do this when we are slightly surprised, and at times also employ it to express fear or entreaty when we are seized with sudden indignation.
1.104
Further, we sometimes clench the hand and press it to our breast when we are expressing regret or anger, an occasion when it is not unbecoming even to force the voice through the teeth in phrases such as What shall I do now? What would you do? To point at something with the thumb turned back is a gesture which is in general just, but is not, in my opinion, becoming to an orator.
