 abstract={The article presents three unpublished seals of Jan Długosz. They have preserved in fi ve copies on two documents and three letters. In the article there are descriptions of the seals, giving their shape, dimensions, images and inscriptions, together with the way in which they were used. Next, there is an analysis of the seals set in the context of a convention established in the circle of cathedral canons. For selected issues, references are made to analogous phenomena existing in the sphragistics of bishops and knights. While discussing the use of the seals, the author asks a question about their possible mutual relationship. Unfortunately, the search for ananswer is hampered by the poor state of preservation of the sources.},
