On the castle gate he found a golden trumpet hanging, under which were written these words—
"Whoever can this trumpet blow,
Shall cause the giant's overthrow."
Jack seized the golden trumpet and blew a mighty blast, which made the gates fly open and shook the castle to its foundations. The giant and the magician, knowing that their end was now near, stood biting their thumbs and shaking with terror. Jack, with his magic sword, soon killed the giant, and the magician was carried off by a whirlwind. The castle vanished away like smoke, and the duke's daughter and all the knights and lovely ladies who had been turned into birds and beasts returned to their proper shape.
Jack's fame rang through the whole country, and the King gave him a large estate to reward him for all his brave and knightly deeds. And Jack married the duke's daughter, and lived in joy and contentment for the rest of his days.
