Once upon a time, though it wasn’t in my time, and it wasn’t in your time, and it wasn’t in anybody’s time, the good and brave knight Sir Percival sallied forth on his trusted steed. Advancing slowly through a wood in the quiet of the afternoon, he came in sight of an old furrier speedily making his way through the underbrush.
He said to the furrier, “Good man, pray where are you going?” Said the furrier, “Good sir knight, I am in great haste. My youngest daughter is gravely ill, and only a medicine made from the blood of a bogey may save her.” And he held up the body of a bogey which he had caught. “And how far have you to travel?” asked Sir Percival. “It is many leagues yet,” said the furrier, “and I am in great fear that I shall arrive too late.”
Then Sir Percival said to him, “Last night God sent me a dream. In my dream I saw a man who carried in his hand a bogey. He placed a silver coin in the bogey’s mouth, then threw both coin and bogey into a pond. Suddenly he transformed into a great bird of prey for the space of one hour.”
Then asked Sir Percival of the furrier, “Have you a silver coin?” He had none. Then Percival, giving him a silver coin and pointing to a nearby pond, said, “Take this coin and place it in the bogey’s mouth. Then throw both coin and bogey into that pond. If you do this, you shall transform into a great bird of prey for the space of one hour. Then you shall fly home quickly.” So the man advanced toward the pond and, putting the coin into the mouth of the bogey, threw both into the pond. And he suddenly transformed into a great bird of prey. The bird grasped the bogey with its talons and flew rapidly away, and the furrier’s daughter was saved.
