Heracles, and the events which followed it, had been narrated in a long poem, in which one version of that hero's multiform legend was fully set forth.
The subjects of the King Oedipus, Oedipus at Colonos, and Antigone, are taken from the Tale of Thebes; the Aias and the Philoctetes are founded on incidents between the end of the Iliad and the taking of Troy; the Electra represents the vengeance of Orestes, the crowning event in the tale of 'Pelops' line'; the Trachiniae recounts the last crisis in the life of Heracles.

Aeschylus in the Seven against Thebes had already represented the young heroine as defying the victorious citizens who forbade the burial of her brother, the rebel Polynices. He allowed her to be supported in her action by a band of sympathizing friends. But in the play of Sophocles she stands alone, and the power which she defies is not that of the citizens generally, but of Creon, whose will is absolute in the State. Thus the struggle is intensified, and both her strength and her desolation become more impressive, while the opposing claims of civic authority and domestic piety are more vividly realized, because if either is separately embodied in an individual will. By the same means the situation is humanized to the last degree, and the heart of the spectator, although strained to the uttermost with pity for the heroic maiden whose life when full of brightest hopes was sacrificed to affection and piety, has still some feeling left for the living desolation of the man, whose patriotic zeal, degenerating into tyranny, brought his city to the brink of ruin, and cost him the lives of his two sons and of his wife, whose dying curse, as well as that of Haemon, is donounced upon him.
In the Oedipus Tyrarnnus, Sophocles goes back to the central crisis of the Theban story. And again he fixes our attention, not so much on the fortunes of the city, or of the reigning house, as on the man Oedipus, his glory and his fall:—
