Abstract
The article presents two important strands of research: the preserved paintings in the present attic of the Latin Rite Archcathedral Basilica in Przemyśl and the polychromy on the stone blocks in the foundation part of this temple. The existing paintings of significant cultural value were made in the late medieval period, an era when the Przemyśl Cathedral had Gothic forms, and the existing paintings circled the walls of the temple below the Gothic wooden ceiling. Based on the current state of research and the extent of damage to the paintings, it was only possible to interpret and read the paintings piecemeal. The article includes their photographs and discusses the painted scenes and ornamentation along with their psychological context. Polychromes in part of the foundation walls of the chancel of the Przemyśl basilica were also studied. The results of the research could confirm the reuse of stone blocks for the construction of the walls of the cathedral’s chancel. In addition, the chemical composition of the mortar structures and polychrome was given. The data provided insight into the mortar and paint technologies used in the medieval era in Przemyśl.
