“I will tell you,” said the old man.  “The Pythia is a wise woman, who lives in the temple.  When anybody asks her a hard question, she takes a three-legged stool, called a tripod, and sets it over the crevice in the floor.  Then she sits on the stool and breathes the strange odor; and instead of losing her senses as other people would do, she talks with Apollo; and Apollo tells her how to answer the question.  Men from all parts of the world go there to ask about things which they would like to know.  The temple is full of the beautiful and costly gifts which they have brought for the Pythia.  Sometimes she answers them plainly, and sometimes she answers them in riddles; but what she says always comes true.”

So Cadmus went to Delphi to ask the Pythia about his lost sister.  The wise woman was very kind to him; and when he had given her a beautiful golden cup to pay her for her trouble, she sat down on the tripod and breathed the strange odor which came up through the crevice in the rock.  Then her face grew pale, and her eyes looked wild, and she seemed to be in great pain; but they said that she was talking with Apollo.  Cadmus asked her to tell him what had become of Europa.  She said that Jupiter, in the form of a white bull, had carried her away, and that it would be of no use to look for her any more.

“But what shall I do?” said Cadmus.  “My father told me not to turn back till I should find her.”

“Your father is dead,” said the Pythia, “and a strange king rules in his place.  You must stay in Greece, for there is work here for you to do.”

“What must I do?” said Cadmus.

“Follow the white cow,” said the Pythia; “and on the hill where she lies down, you must build a city.”

Cadmus did not understand what she meant by this; but she would not speak another word.

“This must be one of her riddles,” he said, and he left the temple.

III.  THE DRAGON.

When Cadmus went out of the temple, he saw a snow-white cow standing not far from the door.  She seemed to be waiting for him, for she looked at him with her large brown eyes, and then turned and walked away.  Cadmus thought of what the Pythia had just told him, and so he followed her.  All day and all night he walked through a strange wild country where no one lived; and two of the young men who had sailed with Cadmus from his old home were with him.

When the sun rose the next morning, they saw that they were on the top of a beautiful hill, with woods on one side and a grassy meadow on the other.  There the cow lay down.

“Here we will build our city,” said Cadmus.

Then the young men made a fire of dry sticks, and Cadmus killed the cow.  They thought that if they should burn some of her flesh, the smell of it would go up to the sky and be pleasing to Jupiter and the Mighty Folk who lived with him among the clouds; and in this way they hoped to make friends with Jupiter so that he would not hinder them in their work.
