There was once an enchantress, who had three sons who loved each other as brothers, but the old woman did not trust them, and thought they wanted to steal her power from her. So she changed the eldest into an eagle, which was forced to dwell in the rocky mountains, and was often seen sweeping in great circles in the sky. The second, she changed into a whale, which lived in the deep sea, and all that was seen of it was that it sometimes spouted up a great jet of water in the air. Each of them only bore his human form for two hours daily.

The third son, who was afraid she might change him into a raging wild beast a bear perhaps, or a wolf, went secretly away. He had heard that a King's daughter who was bewitched, was imprisoned in the Castle of the Golden Sun, and was waiting for deliverance. Those, however, who tried to free her risked their lives; three-and-twenty youths had already died a miserable death, and now only one other might make the attempt, after which no more must come. And as his heart was without fear, he caught at the idea of seeking out the Castle of the Golden Sun. He had already travelled about for a long time without being able to find it, when he came by chance into a great forest, and did not know the way out of it.
