"The giant, who doesn't live far from here, can do nothing with his great body. But his shadow can do a great deal -- in fact, everything. That is why he is most powerful when the sun rises and sets. All one has to do is sit down on the neck of his shadow at nightfall. Then he walks gently toward the shore, and his shadow brings the traveler across the water." (From _The Fairy Tale_ by Johann Wolfgang Goethe)
