Up among the marble walls they went, and beneath the roofs of gold, and stood in the hall of Aietes, while he grew pale with rage.

“Fulfil your promise to us, Child of the blazing Sun,” the heroes cried to King Aietes.  “Give us the serpents’ teeth, and let loose the fiery bulls, for we have found a champion among us, who can win the Golden Fleece!”

Aietes grew more pale with rage, for he had fancied that they had fled away by night, but he could not break his promise, so he gave them the serpents’ teeth.  Then he called his chariot and his horses, and sent heralds through all the town, and all the people went out with him to the dreadful War-god’s field.

There Aietes sat upon his throne, with his warriors on each hand, thousands and tens of thousands clothed from head to foot in steel chain mail.  And the people and women crowded to every window and bank and wall, while the heroes stood together, a mere handful in the midst of that great host.

Chalciope was there, and Medeia, wrapped closely in her veil; but Aietes did not know that she was muttering cunning spells between her lips.

Then Jason cried, “Fulfil your promise, and let your fiery bulls come forth!”

Aietes bade open the gates, and the magic bulls leapt out.  Their brazen hoofs rang upon the ground as they rushed with lowered heads upon Jason, but he never flinched a step.  The flame of their breath swept round him, but it singed not a hair of his head.  And the bulls stopped short and trembled when Medeia began her spell.

Then Jason sprang upon the nearest, and seized him by the horns, and up and down they wrestled, till the bull fell groveling on his knees.  For the heart of the bull died within him, beneath the steadfast eye of that dark witch-maiden and the magic whisper of her lips.

So both the bulls were tamed and yoked, and Jason bound them to the plow and goaded them onward with his lance, till he had plowed the sacred field.  And all the heroes shouted, but Aietes bit his lips with rage, for half of Jason’s work was done.

Then Jason took the serpents’ teeth and sowed them, and waited what would befall.

And Medeia looked at him and at his helmet, lest he should forget the lesson she had taught him.

Now every furrow heaved and bubbled, and out of every clod arose a man.  Out of the earth they arose by thousands, each clad from head to foot in steel, and drew their swords and rushed on Jason where he stood in the midst alone.

The heroes grew pale with fear for him, but Aietes laughed an angry laugh.

Then Jason snatched off his helmet and hurled it into the thickest of the throng.  And hate and fear and suspicion came upon them, and one cried to his fellows, “Thou didst strike me,” and another, “Thou art Jason, thou shalt die,” and each turned his hand against the rest, and they fought and were never weary, till they all lay dead upon the ground.
