Book 11
1.105
Motion is generally divided into six kinds, but circular motion must be regarded as a seventh. The latter alone is faulty when applied to gesture. The remaining motions— that is, forward, to right or left and up or down—all have their significance, but the gesture is never directed to what lies behind us, though we do at times throw the hand back.
1.106
The best effect is produced by letting the motion of the hand start from the left and end on the right, but this must be done gently, the hand sinking to rest and avoiding all appearance of giving a blow, although at the end of a sentence it may sometimes be allowed to drop, but must quickly be raised again: or it may occasionally, when we desire to express wonder or dissent, spring back with a rapid motion. In this connexion the earlier instructors in the art of gesture rightly added that the movement of the hand should begin: and end with the thought that is expressed. Otherwise the gesture will anticipate or lag behind the voice, both of which produce an unpleasing effect.
