Charlemagne asks his wife if any king wears a crown better than he does. To Charlemagne's outrage, she answers that the (fictional) Byzantine Emperor Hugo wears one better. Under the pretense of a pilgrimage, Charlemagne and his Twelve Peers set out for the east. They go to Jerusalem first, where they meet the patriarch, who gives them many important relics to take back, and also the title of Emperor. On the way home, they stop at Constantinople, a very beautiful and rich city free from theft and poverty. There they meet Hugo, indeed a very handsome and glorious king, standing on a golden plough. They are invited to the palace, an edifice which stands on a pole and revolves when the wind revolves.
