Next morning, therefore, she called her maidens and went out in her chariot to the fane of Hecate on the plain beyond the city, a place where she was often wont to go to gather herbs. There Jason met her, and he sacrificed his pride to beg her assistance. She was torn between love for him and a sense of duty to her father; but yet love was the stronger, and she promised him her aid. Long they talked together in that wilderness till the shades of evening fell and her attendants became uneasy at her long tarrying. She gave him a magic drug that would render his body and arms invulnerable against all attack, and gave him also minute directions for his guidance in his dreadful conflict. And Jason saw how beautiful and tender she was, and love for her awoke in his heart, and he wooed her with gentle words, and vowed that if she would go with him to Greece she should there be made his honored wife. Evening drew on, and Medea went sadly back to her night of anguished vigil in her palace in the city, while Jason prepared himself for his doubtful conflict. At midnight he bathed alone in the sacred river. Then he digged a pit in the plain as Medea had directed him, and offered a lamb by the pit's brink, and kindled a pyre and burned the carcase. Mingled libations he also poured, and then, calling on Hecate, drew back and strode from the place, and looked not once behind him at the awful queen he had invoked, nor the shapes of fear that accompanied her, nor turned at the wild baying of the hounds of hell. Then he sprinkled his corslet, his helm, and his arms with the drug Medea gave him, and his comrades proved his harness with all their might and main, whose ringing blows fell harmless upon it. Then he sprinkled his own limbs with the magic drug and fared forth invincible. At dawn, the heroes sailed in the _Argo_ up the river till they came near to the plain of Mars, and there anchored. King Æetes came out from the city in procession to the lists, and all the men of Colchis were gathered on the one hand and the heroes on the other to watch the outcome of this terrible strife. So Jason set to his task. Bearing with him his helm full of the dragon's teeth he crossed the field, and there saw the brazen yoke lying, and the plow of massive stone. Suddenly, from their lair, the bulls rushed out together and bore down upon him. Jason, setting his feet wide, caught their charge on his shield and withstood the shock. Mightily he seized the horn of one of the monsters, haled with all his strength, and striking its hoof with his foot cast it down on its knees. And, to the amazement of all, he did likewise to its fellow. Then he cast away his shield, and holding them down set the brazen yoke on their necks. All marveled at his superhuman strength. The brow of Æetes was black, but the heroes rejoiced and cheered their leader right lustily.
