The lost stained glass windows of the church of the Franciscan Monastery in Cluj-Napoca

Summary/Abstract: This study deals with 96 glass fragments discovered during the archaeological research carried out in 2013 inside the Franciscan Monastery in Cluj-Napoca. To date these findings, two variants were proposed. Based on optical analysis, analogies with other artefacts from the history of art, and in accordance with the architectural history of the building, there resulted the hypothesis that the fragments might be dated to the 16th century. The study continued by determining the chemical composition of selected windowpane fragments using Ion Beam Analysis (IBA) methods, namely Particle-Induced X-ray Emission (PIXE) and Particle Induced Gamma-ray Emission (PIGE). Compositional data revealed that the fragments are much more recent, most likely being parts of the stained-glass windows mounted during the campaigns of restoration and reconstruction of various historical monuments from Transylvania from the end of the 19th century and beginning of the 20th century.
