The paper analyses the techniques and methods of creating propaganda narratives about Lutherans in the chronicle of Dominican monk Simon Grunau (the early 16th c.). It examines how, during the Reformation, in the debates of the propaganda character between its supporters and opponents, narratives or their complexes were used with the intention to belittle the image and the arguments of the opponents. It also explains how the Dominicans’ common European experience of the fight against the spreading Reformation was used in the stories of Grunau’s chronicle about the Reformation gaining a foothold in Prussia.
