This scalable tool addresses gaps in regional-scale risk assessments, offering a practical framework for conservation and resource management in vulnerable natural heritage areas.
A Contribution to the History of Repentance Prayers in the Slavic South during the 15th Century
A newly analyzed autograph by Vladislav the Grammarian, found within the Trebnik of Monk David (1480s) at Rila Monastery, reveals a significant shift in penitential prayer practices among Orthodox Christians following the Ottoman conquest of Constantinople in 1453. This text, titled A Very Useful Confession for Unction, demonstrates a marked increase in repentance prayers, suggesting that the Ottoman invasion was perceived as divine punishment for Christian sins. The manuscript, part of a broader Slavonic Trebnik tradition, includes unique textual additions linked to the sacrament of anointing (eleosvet), indicating its relevance during times of communal or individual spiritual crisis. While the Greek prototype remains unidentified, its structure aligns with known patterns of sin accumulation in penitential literature, offering rare insight into 15th-century Orthodox theological responses to geopolitical upheaval.
Bulgarian culture and space in the religious context
The Testament of John of Rila, a significant metahistorical text within Bulgarian cultural heritage, reveals profound interactions with geographical and cultural landscapes through the lens of Juri Lotman's semiotic method. This study highlights how the text functions as a bridge between 'cultural centrality' and 'cultural periphery,' shaping Bulgaria's religious and spatial identity over generations. By analyzing Rila Monastery as a physical location, the research uncovers hidden dimensions of 'semiotic spheres,' demonstrating their role in structuring Bulgarian metahistorical tradition. The approach combines close textual analysis with spatial and cultural mapping to decode complex relationships between text, reader, and environment.
Characterization of art materials and degradation processes in the exterior wall paintings of the main church of Rila Monastery, Bulgaria
A groundbreaking analysis of the exterior wall paintings at Rila Monastery, Bulgaria—a UNESCO World Heritage Site and the last large-scale example of Eastern Orthodox mural art—reveals significant degradation linked to atmospheric exposure. The study identified natural pigments like red ochre and green earth alongside synthetic ones such as ultramarine and vermilion, which remain stable. However, minium (lead-based pigment) has chemically transformed into black plattnerite or white lead carbonate, altering the paintings' appearance. Emerald green pigment also showed partial degradation without major color changes. The research used a multi-technique approach, including ATR-FTIR, Raman spectroscopy, and SEM-EDS, to characterize materials and decay products like gypsum and calcium oxalate. Binders confirmed the use of egg-tempera, with chemical degradation suggested by metal oxalates. Notably, the study highlights the introduction of emerald green pigment and synthetic ultramarine, diverging from traditional Byzantine practices.
