Chap. CLIX.The Representation of an Orator and his Audience.

If you have to represent a man who is speaking to a large assembly of people, you are to consider the subject matter of his discourse, and to adapt his attitude to such subject. If he means to persuade, let it be known by his gesture. If he is giving an explanation, deduced from several reasons, let him put two fingers of the right hand within one of the left, having the other two bent close, his face turned towards the audience, with the mouth half open, seeming to speak. If he is sitting, let him appear as going to raise himself up a little, and his head be forward. But if he is represented standing, let him bend his chest and his head forward towards the people.

The auditory are to appear silent and attentive, with their eyes upon the speaker, in the act of admiration. There should be some old men, with their mouths close shut, in token of approbation, and their lips pressed together, so as to form wrinkles at the corners of the mouth, and about the cheeks, and forming others about the forehead, by raising the eyebrows, as if struck with astonishment. Some others of those sitting by, should be seated with their hands within each other, round one of their knees; some with one knee upon the other, and upon that, one hand receiving the elbow, the other supporting the chin, covered with a venerable beard.
