Having got the child on his back, the animal gave a leap into the air, and came down so like a feather that Europa did not know when his hoofs touched the ground.  He then began a race to that part of the flowery plain where her three brothers were, and where they had just caught their splendid butterfly.  Europa screamed with delight; and Phoenix, Cilix, and Cadmus stood gaping at the spectacle of their sister mounted on a white bull, not knowing whether to be frightened or to wish the same good luck for themselves.  The gentle and innocent creature (for who could possibly doubt that he was so?) pranced round among the children as sportively as a kitten.  Europa all the while looked down upon her brothers, nodding and laughing, but yet with a sort of stateliness in her rosy little face.  As the bull wheeled about to take another gallop across the meadow, the child waved her hand, and said, “Good-by,” playfully pretending that she was now bound on a distant journey, and might not see her brothers again for nobody could tell how long.

“Good-by,” shouted Cadmus, Phoenix, and Cilix, all in one breath.

But, together with her enjoyment of the sport, there was still a little remnant of fear in the child’s heart; so that her last look at the three boys was a troubled one, and made them feel as if their dear sister were really leaving them forever.  And what do you think the snowy bull did next?  Why, he set off, as swift as the wind, straight down to the seashore, scampered across the sand, took an airy leap, and plunged right in among the foaming billows.  The white spray rose in a shower over him and little Europa, and fell spattering down upon the water.

Then what a scream of terror did the poor child send forth!  The three brothers screamed manfully, likewise, and ran to the shore as fast as their legs would carry them, with Cadmus at their head.  But it was too late.  When they reached the margin of the sand, the treacherous animal was already far away in the wide blue sea, with only his snowy head and tail emerging, and poor little Europa between them, stretching out one hand toward her dear brothers, while she grasped the bull’s ivory horn with the other.  And there stood Cadmus, Phoenix, and Cilix, gazing at this sad spectacle, through their tears, until they could no longer distinguish the bull’s snowy head from the white-capped billows that seemed to boil up out of the sea’s depths around him.  Nothing more was ever seen of the white bull—­nothing more of the beautiful child.

This was a mournful story, as you may well think, for the three boys to carry home to their parents.  King Agenor, their father, was the ruler of the whole country; but he loved his little daughter Europa better than his kingdom, or than all his other children, or than anything else in the world.  Therefore, when Cadmus and his two brothers came crying home, and told him how that a white bull had carried off their sister, and swam with her over the sea, the king was quite beside himself with grief and rage.  Although it was now twilight, and fast growing dark, he bade them set out instantly in search of her.
