King Æetes had known very well how it would be; but Jason, when night, came, retired to the chamber which had been assigned to him in despair. Midnight found him still waking, when the door opened, and there stood before him, holding a lamp, a tall and beautiful woman, dark-skinned, black-eyed, and with long black hair—beautiful, as I have said, but terrible in her beauty.
“You have no cause for shame,” said she, in a softer voice than he would have expected. “They were enchanted bulls: and not ten times your number would have fared better. This is a nation of enchanters, whose king knows how to laugh you Greeks and your boasted bravery to scorn. But I am the greatest of all enchanters; and I will teach you how to tame the bulls—if you will promise me one thing.”
“Anything!” said Jason. “Only tell me who you are, and what you require of me.”
“I am Medea, the king’s daughter,” said she. “And what I require is that you shall marry me this night in the Temple of Hecate, the Queen of Witches, and that you will swear before her altar to be true and faithful to me forever.”
“Gladly,” exclaimed Jason, who, to succeed in his adventure, would have gladly sworn anything to any one.
So he followed her to the Temple of Hecate, the Witch-Queen, and there, with many strange and dreadful rites, he married her, and swore to be true and faithful to Medea forever. Then she gave him a magic herb, and said:—
“This will tame the bulls.” And she also gave him a sling and a stone, adding, “Use this when there is need.”
The next morning Jason went into the field alone. As soon as the scent of the herb reached the bulls’ nostrils they crouched at his feet; and when Æetes and his Court, and the Greek princes with them, came forth, lo! there was Jason quietly driving a plough drawn by the bulls, who were now as tame as common oxen.
“Some one has been betraying me,” thought the king angrily. But he hid his anger, and said: “You have done very well so far. I am sorry to say, however, that the Golden Fleece has other guards. Do you see these serpents’ teeth? You must sow these in the furrow you have made with your plough—and then the gods help you if they can.”
So Jason, having finished his ploughing, sowed the serpents’ teeth as if they were seeds of corn. And then from that seed sprang up, in less than an hour, a strange harvest—an army of giants, as many as the stalks of wheat in a wide field, who rushed upon Jason and the Greeks, and trampled them to the ground.
