Symonds tells us that Æschylus was the great example of unconscious art among Greek playwrights, and that he exemplifies Plato's theory of poetry.
Æschylus's creation Cassandra is a good illustration of a character in an ecstatic state. Cassandra is both prophetess and poetess, and her cries move us to this day, when much of Æschylus's moral and religious philosophy bores and irritates us. She is the incarnation of woman suffering. She was ravished at Troy by Ajax and was given to Agamemnon as prisoner of war, she the princess, daughter of Priam and Hecuba. She had lost most of the members of her family and now anticipated great trouble for Agamemnon whose wife Claetemnestrae was unfaithful to him. She also foresaw her own death at the queen's hands, but it was her punishment that her prophecies would not be heeded. She is partly mad, but hers is the poetic frenzy, tempered by logic. Her most meaningless ravings are full of meaning. They are poetry not because of the metre in which they are rendered, but because of the rational ecstasy. This ecstasy remains intact even in the English prose translation.
Nietzsche divided art into Apollonian and Dionysian. He found that the Dionysian state depended on emotional or orgiastic intoxication. He perceived that the ecstasy in this state was largely of a sexual character. As he boldly put it, "The desire for art and beauty is an indirect longing for the ecstasy of sexual desire, which gets communicated to the brain." This is the thesis that Freud developed. Croce, who has, however, something of the metaphysician and mystic in him, is not in sympathy with this view, for he ridicules the idea that the genesis of aesthetism lies in the desire of the male for the female. Yet he agrees with Freud in the conception that art is a means of curing oneself of sexual neurosis. "By elaborating his impressions," says Croce, "man frees himself from them. By objectifying them, he removes them from him and makes himself their superior. The liberating and purifying function of art is another aspect and another formula of its character and activity. Activity is the deliverer, just because it drives away passivity."
Finely put, indeed, are the words of Nietzsche's views on ecstasy. "To the existence of art, to the existence of any aesthetic activity or perception whatsoever, a preliminary psychological condition is indispensable, namely ecstasy. Ecstasy must first have intensified the sensitiveness of the whole mechanism; until this takes place art is not realized.
