The Prussian King was jealous of the lamb with a golden fleece of King Matthias and decided to obtain it by any means. They make a bet on whether the shepherd looking over the lamb, who is famous for always telling the truth, lies or not. The Prussian King, with the slyness of his daughter, and of course with some sacrifice, obtains the skin of the lamb with the golden fleece. The shepherd is sad, he is suffering and sinks deeper and deeper into the maze of lies – until finally he chooses the straight path – and tells the truth about what exactly happened with the lamb with the golden fleece. This is how they win half of the Prussian King's country, and even also the Prussian King's daughter.
