Infuła i korona. Kilka uwag o pieczęciach Karola Ferdynanda Wazy

Charles Ferdinand Vasa, son of the Polish king Sigismund III, bishop of Wrocław and Płock, duke of Opole and Racibórz, owing to his heritage and offices was in possession of the most expansive sigillography system among all princes of the Vasa dynasty. The article presents previously unknown seals, as well as analysis of the relations linking them, and an attempt is made at defining the functions characterising the sigillography of Charles Ferdinand Vasa’s seals of a mixed (church and lay) nature.
