“Repose and tranquillity may be regarded as the effect of that composed manner which the Grecians studied to show in their actions and gestures. Among them, a hurried gait was regarded as contrary to the idea of decent deportment, and partaking somewhat of expressive boldness.... While on the other hand, slow and regulated motions of the body were proofs among the ancients of a great mind.
“The highest idea of tranquillity and composure is found expressed in the representations of the divinities; so that from the father of the gods to the inferior deities, their figures appear free from the influence of any affection. The greatest of the poets thus describes Jupiter as making all Olympus tremble by merely moving his eyebrow or shaking his locks.... All the figures of Jupiter are not however made in the same style.
“The Vatican Apollo represents this god quiet and tranquil after the death of the serpent Python which he had slain with a dart, and should also express a certain contempt for a victory so easy to him. The skilful artist, who wished to imbody the most beautiful of the gods, has depicted anger in the nose, which according to the most ancient poets was the seat of it, and contempt in the lips: contempt is expressed by the drawing up of the under lip, and anger by the expansion of the nostrils.
“The expression of the passions in the face should accord with the attitude and gestures of the body; and the latter should be suitable to the dignity of the gods in their statues and figures: from this results its propriety.
“In representing the figures of heroes, the ancient artist exercised equal care and judgment; and expressed only those human affections which are suitable for a wise man, who represses the violence of his passions, and scarcely allows a spark of the internal flame to be seen, so as to leave to those who are desirous of it, the trouble of finding out what remains concealed.
“We have examples of this in two of the most beautiful works of antiquity, one of which is the image of the fear of certain death, the other of suffering exceeding anguish.
“Niobe and her daughters, against whom Diana shot her fatal arrows, are represented as seized with terror and horror, in that state of indescribable anguish, when the sight of instant and inevitable death deprives the mind of the power of thought. Of this state of stupor and insensibility, the fable gives us an idea in the metamorphosis of Niobe into a stone; and hence Æschylus introduces her in his tragedy as stunned and speechless. In such a moment, when all thought and feeling ceases, in a state bordering upon insensibility, the appearance is not altered nor any feature of the face disturbed, and the mighty artist could here depict the most sublime beauty, and has indeed done so. Niobe and her daughters are, and ever will be, the most perfect models of beauty.
“Laocoon is the image of the most acute grief, that puts the nerves, the muscles, and the veins, in action. His blood is in a state of extreme agitation from the venomous bite of the serpents; every part of his body evinces pain and suffering; and the artist has put in motion, so to speak, all the springs of nature, and thus made known the extent of his art and the depth of his knowledge. In the representation, however, of this excessive torment, we can still recognise the conduct of a brave man struggling against his misfortunes, stifling the emotions of his anguish, and striving to repress them.”
“The ancient artists have preserved this air of composure even in their dancing figures, except the Bacchanals; and thus an opinion obtained that the action of their figures should be modelled on the manners adopted in their ancient dances, and therefore, in their later dances, the ancient figures served as a model to the performers to prevent their overstepping the bounds of a modest deportment:
