He became especially accomplished in the art of playing the rommelpot, an instrument which is constructed out of a round pot, a bladder, and a straight piece of straw. And this is the way he played it. First of all he moistened the bladder and held it over the pot. Then he drew the centre of the bladder round the joint of a straw which itself was attached to the bottom of the pot. Finally he stretched the bladder as tightly as he dared over the sides of the pot. In the morning, when the bladder was dry, it sounded like a tambourine when struck, and if one rubbed the straw it gave forth a humming sound as fine in tone as that of any violin. And Ulenspiegel, with his musical pot that played music like the baying of a mastiff, went out with the other children on the day of Epiphany carrying a star made of luminous paper, and singing carols. Sometimes an artist would come to Damme to paint the members of one of the Guilds, upon their knees. Ulenspiegel was always anxious to see how the artist worked, and he would beg to be allowed to grind the colours in return for nothing but a slice of bread, three liards, and a pint of ale. But while he worked away at the grinding he would carefully study the method of his master. When the artist went away Ulenspiegel would endeavour to paint pictures like him; and his favourite colour was scarlet. In this way he tried to paint the portraits of Claes, of Soetkin, and of Katheline and Nele, as well as those of the pots and pans in the kitchen. When Claes beheld these works of art he predicted that if only he worked hard enough Ulenspiegel would one day be able to earn florins by the dozen for painting the inscriptions on the festal cars, or speel-wagen as they are called in Zeeland and the land of Flanders. Ulenspiegel also learnt to carve in wood and in stone, for once a master-mason came to Damme to carve a stall in the choir of Notre Dame. And this stall was made in such a way that the Dean--who was an old man--could sit down when he so desired, yet seem to all appearance as if he were still standing upright. It was Ulenspiegel too who made the first carved knife-handle ever used by the people of Zeeland. He fashioned this handle in the form of a cage. Inside was a death's head that moved; and above it a hound couchant. And this was the signification: "Soul true till death." Thus it was that Ulenspiegel began to fulfil the prophecy that Katheline had made when she said that he would be painter, sculptor, workman, nobleman, all in one. For you must know that from father to son the family of Claes bore arms three pint pots argent au naturel on a ground bruinbier. But Ulenspiegel would stick to no one profession, and Claes told him that if he went on in this good-for-nothing way he would chase him out of the house. XIV On his return from the wars, the Emperor wanted to know why his son Philip was not there to welcome him.
