Long and strenuous was the contest that succeeded, each of the heroes fiercely attacking the gate adjudged to him. But the gods were on the side of the Thebans and every assault proved in vain. Parthenopæus, one of the seven, was killed by a stone, and another, Capaneus, while furiously mounting the walls from a scaling-ladder, was slain by a thunderbolt cast by Jupiter, and fell dead to the earth.
The assailants, terrified by this portent, drew back, and were pursued by the Thebans, who issued from their gates. But the battle that was about to take place on the open plain was stopped by Eteocles, who proposed to settle it by a single combat with his brother Polynikes, the victory to be given to the side whose champion succeeded in this mortal duel. Polynikes, filled with hatred of his brother, eagerly accepted this challenge. Adrastus, the leader of the assailing army, assented, and the unholy combat began.
Never was a more furious combat than that between the hostile brothers. Each was exasperated to bitter hatred of the other, and they fought with a violence and desperation that could end only in the death of one of the combatants. As it proved, the curse of Œdipus was in the keeping of the gods, and both fell dead,—the fate for which their aged father had prayed. But the duel had decided nothing, and the two armies renewed the battle.
And now death and bloodshed ran riot; men fell by hundreds; deeds of heroic valor were achieved on either side; feats of individual daring were displayed like those which Homer sings in the story of Troy. But the battle ended in the defeat of the assailants. Of the seven leaders only two survived, and one of these, Amphiaraüs, was about to suffer the fate he had foretold, when Jupiter rescued him from death by a miracle. The earth opened beneath him, and he, with his chariot and horses, was received unhurt into her bosom. Rendered immortal by the king of the gods, he was afterwards worshipped as a god himself.
Adrastus, the only remaining chief, was forced to fly, and was preserved by the matchless speed of his horse. He reached Argos in safety, but brought with him nothing but "his garment of woe and his black-maned steed."
Thus ended, in defeat and disaster to the assailants, the first of the celebrated sieges of Thebes. It was followed by a tragic episode which remains to be told, that of the sisterly fidelity of Antigone and her sorrowful fate. Her story, which the dramatists have made immortal, is thus told in the legend.
After the repulse of his foes, King Creon caused the body of Eteocles to be buried with the highest honors; but that of Polynikes was cast outside the gates as the corpse of a traitor, and death was threatened to any one who should dare to give it burial. This cruel edict, which no one else ventured to ignore, was set aside by Antigone, the sister of Polynikes. This brave maiden, with warm filial affection, had accompanied her blind father during his exile to Attica, and was now returned to Thebes to perform another holy duty. Funeral rites were held by the Greeks to be essential to the repose of the dead, and Antigone, despite Creon's edict, determined that her brother's body should not be left to the dogs and vultures. Her sister, though in sympathy with her purpose, proved too timid to help her. No other assistance was to be had. But not deterred by this, she determined to perform the act alone, and to bury the body with her own hands.
In this act of holy devotion Antigone succeeded; Polynikes was buried. But the sentinels whom Creon had posted detected her in the act, and she was seized and dragged before the tribunal of the tyrant. Here she defended her action with an earnestness and dignity that should have gained her release, but Creon was inflexible in his anger. She had set at naught his edict, and should suffer the penalty for her crime. He condemned her to be buried alive.
Sophocles, the dramatist, puts noble words into the mouth of Antigone. This is her protest against the tyranny of the king:
