The unique panegyric of the Szydłowiecki family, one of the most important examples of Polish Renaissance miniature painting ascribed to Stanisław Samostrzelnik, is also a source of reliable information about the objects founded by members of this family. Apart from a glorification of particular representatives of the Szydłowiecki family, who, connected with the royal court, achieved very high ranks in state administration and the Church hierarchy, the text contains also extensive information about their participation in the foundations of numerous objects, not to mention their own residences. The list is impressive, a feature which gives rise to certain doubts concerning its reliability, especially since it refers to a very brief period in the career of the family (two generations). The author attempted to confirm information found in Liber either by resorting to archival material or by identifying the mentioned objects. She also prepared historical documentation for the reconstruction of Szydłowiec Castle, and took part in architectonic research concerning this object and its conservation. The latest discoveries confirming the data contained in Liber include polychromies on the walls of the parish church in Szydłowiec.
