Still, the change is only commensurate with the force of the circumstances. We comprehend it, while at the same time we are forced to marvel at the profound skill of the poet, who, in the first tragedy, has presented to our eyes the hot-tempered king reduced to abject humiliation, and in the second has shown us the same man dignified, and purified by the dealings of the heavy hand of God. Set aside by his calamity, and severed from the common lot of men, Oedipus has submitted to the divine will and has communed with unseen powers. He is therefore now environed with a treble mystery--with the mystery of his awful past, the mystery of his god-conducted present, the mystery of his august future. It was by such masterly delineation of character that Sophocles threw the old Æschylean dogma of Nemesis into the background, and moralized his tragedy without sacrificing an iota of its religious force. Aristotle, speaking of the highest tragic art, says that its object is to represent an #êthos#, a permanent habit of moral temper. Careless or bad art allows impossible incongruities in the delineation of character, whereas the true poet maintains identity throughout. If this be so, Sophocles deserves the title of #êthikôtatos# in the very highest sense. As a further illustration of the divergence of Sophocles from the Æschylean dogma of Nemesis, it is worth while to mention the _Antigone_. This play takes us beyond the region of hereditary guilt into the sphere of moral casuistry; its tragic interest depends not upon the evolution of an ancestral curse, although Antigone is incidentally involved in the crime of her brothers, but upon the conflict of duties in a single heart. Antigone, while obeying the law of her conscience, is disobeying the command of her sovereign. She acted rightly; yet her offence was sufficient to cause her legal death, and this death she chose with open eyes. It is in the person of Creon that the old moral of Nemesis is drawn. Like Oedipus, he treats the warnings of Teiresias with scorn, and persists in his criminal persecution of the dead Polyneices. Shaken at last by the seer's vaticinations, he rescinds his orders, but too late. Antigone has hanged herself in prison; Hæmon curses his father, and stabs himself upon her corpse; Eurydice, maddened with grief, puts an end to her own life; and thus the house of the tyrant is left unto him desolate. It is quite impossible by any phrases of mere criticism to express the admiration which every student of Sophocles must feel for the profundity of his design, for the unity of his art, and for the firmness with which he has combined the essential religious doctrines of Greek tragedy with his own ethical philosophy.
