The statues of the ancients make this principle of aesthetics sensible to us; but it is difficult to reduce to conceptions and express in words what the very inspection of ancient statues makes the senses feel in so lively a manner. The group of Laocoon and his children can give to a great extent the measure of what the plastic art of the ancients was capable of producing in the matter of pathos. Winckelmann, in his "History of Art,", says: "Laocoon is nature seized in the highest degree of suffering, under the features of a man who seeks to gather up against pain all the strength of which the mind is conscious. Hence while his suffering swells his muscles and stretches his nerves, the mind, armed with an interior force shows itself on his contracted brow, and the breast rises, because the breathing is broken, and because there is an internal struggle to keep in the expression of pain, and press it back into his heart. The sigh of anguish he wishes to keep in, his very breath which he smothers, exhaust the lower part of his trunk, and works into his flanks, which make us judge in some degree of the palpitations of his visceral organs. But his own suffering appears to occasion less anguish than the pain of his children, who turn their faces toward their father, and implore him, crying for help. His father's heart shows itself in his eyes, full of sadness, and where pity seems to swim in a troubled cloud. His face expresses lament, but he does not cry; his eyes are turned to heaven, and implore help from on high. His mouth also marks a supreme sadness, which depresses the lower lip and seems to weigh upon it, while the upper lip, contracted from the top to the bottom, expresses at once both physical suffering and that of the soul. Under the mouth there is an expression of indignation that seems to protest against an undeserved suffering, and is revealed in the nostrils, which swell out and enlarge and draw upwards. Under the forehead, the struggle between pain and moral strength, united as it were in a single point, is represented with great truth, for, while pain contracts and raises the eyebrows, the effort opposed to it by the will draws down towards the upper eyelid all the muscles above it, so that the eyelid is almost covered by them. The artist, not being able to embellish nature, has sought at least to develop its means, to increase its effect and power. Where is the greatest amount of pain is also the highest beauty. The left side, which the serpent besets with his furious bites, and where he instils his poison, is that which appears to suffer the most intensely, because sensation is there nearest to the heart. The legs strive to raise themselves as if to shun the evil; the whole body is nothing but movement, and even the traces of the chisel contribute to the illusion; we seem to see the shuddering and icy-cold skin."
