Thus, in substance De Quincey; who makes too little, perhaps, of the matter of that last sentence; and too much of what goes before. We may say that it was rather the grand impersonal theory of the art that created the outward condition; not the conditions that created the theory. Mahaffy went to Athens and measured the theater; and found it not so big by any means. They could have worked out our theories and practice in it, had they wanted to, so far as that goes. Coarse buffoonish country festivals do not of themselves evolve into grand art or solemn occasions; you must seek a cause for that evolution, and find it in an impulse arisen in some human mind. Or minds indeed; for such impulses are very mysterious. The Gods sow their seed in season; we do not see the sowing, but presently mark the greening of the brown earth. The method of the Mysteries--drama serious and religious--had been drifting outwards: things had been growing to a point where a great creative Soul could take hold of them and mold them to his wish. If Aeschylus was not an Initiate of Eleusis, he had learnt, with the Pythagoreans, the method of the Mysteries of all lands. He knew more, not less, than the common pillars of the Athenian Church and State. I imagine it was he, in those thirteen consecutive years of his victories, who in part created, in part drew from his Pythagorean knowledge, those conventions and circumstances for Tragedy which suited him--rather than that conventions already existing imposed formative limits on him. His genius was aloof, impersonal, severe, and of the substance of the Eternal; such as would need precisely those conventions, and must have created them had they not been there. Briefly, I believe that this is what happened. Sent by Pythagoras to do what he could for Athens and Greece, he forged this mighty bolt of tragedy to be his weapon. The theory of modern drama is imitation of life. It has nothing else and higher to offer; so, when it fails to imitate, we call it trash. But the theory of Aeschylean Tragedy is the illumination of life. Illumination of life, through a medium quite unlike life. Art begins on a spiritual plane, and works down to realism in its decadence; then it ceases to be art at all, and becomes merely copying what we imagine to be nature,--nature, often, as seen through a diseased liver and well-atrophied pineal gland.
