The critical condition of the Greek people itself at the epoch of the drama is worth minute consideration. During the two previous centuries, the whole of Hellas had received a long and careful education: at the conclusion came the terrible convulsion of the Persian war. After the decay of the old monarchies, the Greek states seethed for years in the process of dissolution and reconstruction. The colonies had been founded. The aristocratic families had striven with the mob in every city; and from one or the other power at times tyrants had risen to control both parties and oppress the commonwealth. Out of these political disturbances there gradually arose a sense of law, a desire for established constitutions. There emerged at last the prospect of political and social stability. Meanwhile, in all departments of art and literature, the Greeks had been developing their genius. Lyrical, satirical, and elegiac poetry had been carried to perfection. The Gnomic poets and the Seven Sages had crystallized morality in apothegms. Philosophy had taken root in the colonies. Sculpture had almost reached its highest point. The Greek games, practised through nearly three hundred years, had created a sense of national unity. It seemed as if all the acquirements and achievements of the race had been spread abroad to form a solid and substantial base for some most comprehensive superstructure. Then, while Hellas was at this point of magnificent but still incomplete development, there followed, first, the expulsion of the Peisistratids from Athens, which aroused the spirit of that mighty nation, and then the invasion of Xerxes, which electrified the whole Greek world. It was this that inflamed the genius of Greece; this transformed the race of thinkers, poets, artists, statesmen, into a race of heroes, actors in the noblest sense of the word. The struggle with Persia, too, gave to Athens her right place. Assuming the hegemony of Hellas, to which she was fore-destined by her spiritual superiority, she flashed in the supreme moment which followed the battle of Salamis into the full consciousness of her own greatness. It was now, when the Persian war had made the Greeks a nation of soldiers, and had placed the crown on Athens, that the drama--that form of art which combines all kinds of poetry in one, which subordinates sculpture, painting, architecture, music, dancing, to its own use, and renders all arts subservient to the one end of action--appeared in its colossal majesty upon the Attic stage.
