The notion of justice, legal and punitive European systems of the past is presented at the exhibition of 79 books published as early as the 15th century, as well as maps, travel, historical and literary works. The nature of law, rather complicated and ambiguous, served as basis for the development of European legal systems from the Middle Ages to the 19th century. Their ambiguity is best expressed through the words of Jan Kochanowski: "Laws are as fair as a spider's webs. A sparrow will fly through them, but a fly will die".
