Institutio Oratoria

One of the commonest of all the gestures consists in placing the middle finger against the thumb and extending the remaining three: it is suitable to the exordum, the hand being moved forward with an easy motion a little distance both to right and left, while the head and shoulders gradually follow the direction of the gesture. It is also useful in the statement of facts, but in that case the hand must be moved with firmness and a little further forward, while, if we are reproaching or refuting our adversary, the same movement may be employed with some vehemence and energy, since such passages permit of greater freedom of extension.

On the other hand, this same gesture is often directed sideways towards the left shoulder: this is a mistake, although it is a still worse fault to thrust the arm across the chest and gesticulate with the elbow. The middle and third fingers are also sometimes turned under the thumb, producing a still more forcible effect than the gesture previously described, but not well adapted for use in the exordium or state-

But when three fingers are doubled under the thumb, the finger, which Cicero [*](de Or. II. xlv. 188. ) says that Crassus used to such effect, is extended. It is used in denunciation and in indication (whence its name of index finger), while if it be slightly dropped after the hand has been raised toward the shoulder, it signifies affirmation, and if pointed as it were face downwards toward the ground, it expresses insistence. It is sometimes also used to indicate number.

Again, if its top joint is lightly gripped on either side, with the two outer fingers slightly curved, the little finger rather less than the third, we shall have a gesture well suited for argument. But for this purpose the same gesture is rendered more emphatic by holding the middle joint of the finger and contracting the last two fingers still further to match the lower position of the middle finger and thumb.
