+  daughters were all beautiful; and the youngest was so beautiful that the sun
+  itself, which has seen so much, was astonished whenever it shone in her face.
+  Close by the king’s castle lay a great dark forest, and under an old lime-tree
+  in the forest was a well, and when the day was very warm, the king’s child
+  went out into the forest and sat down by the side of the cool fountain; and
+  when she was bored she took a golden ball, and threw it up on high and caught
+  it; and this ball was her favorite plaything.
