The numerous cimelia of the Kórnik Library include Stanisław Sarnicki’s work Descriptio veteris ac novae Poloniae, printed by Aleksy Rodecki in Cracow in 1585. It is protected by a parchment binding with orientalising decoration marked with a supralibros dedicated by Jan Sienieński to King Stephen Báthory. In view of a scant number of the surviving bookbinding bathoriana, the paper provides a book cover-focused analysis of the work. It makes it possible to examine the binding against the Polish bookbinding art of the late 16th century, identify its maker, link it to other bindings of printed books from Báthory’s book collection, and picture the connections between the decoration of the covers and the illustrations of the publication the binding protected.
