The paper is focused on cooperation between papal collectors and Italian merchants in thirteenth-century Central Europe. The author argues that the concentration of papal collections at the court of Bruno of Schauenburg, Bishop of Olomouc, in the early 1260s stimulated long-distance trade in this Moravian city, as is evident from archaeological finds of Venetian grossi and glass.
He deals with the size of collectoria and financial amounts appointed for collectors. His aim is likewise to bring into focus connections between the 1299 conflict among merchants in Florence and the arrival of some of them to Central Europe.
