Abstract (AI)
Abstract The unique pre-Mongolian twelfth century wall painting from the Christ's Transfiguration Cathedral of the Mirozhsky Monastery in Pskov (Russia) have been investigated. A little less than 200 XRF spectra were collected in situ by portable spectrometer. Moreover 19 samples were subjected to additional in-depth laboratory analysis by six complimentary physico-chemical methods: neutron activation analysis, Fourier transform infrared spectroscopy, micro-Raman spectroscopy, polished cross-sections, polarized microscopy, and chemical microanalysis. Pigments and plasters from the interior painting, fragments found during archaeological excavations, samples from exterior murals, and sample of salt efflorescence were analyzed. The samples included the author's twelfth century painting as well as late repaintings. The composition of pigments and the number of painting layers were determined. Conclusions about organic binder presence or absence, and the painting technique were drawn. The results obtained will be used for restoration and conservation works.
Key Findings
1
Analysis distinguished original twelfth-century paintings from later repaintings across interior murals, exterior fragments, and archaeological materials.
2
Nearly 200 portable XRF spectra and 19 samples analyzed by six physico-chemical techniques identified the compositions of pigments and plasters.
3
Results concerning pigments, plasters, binders, and salt efflorescence provide an analytical basis for restoration and conservation works.
4
The investigation determined the number of painting layers and assessed the presence or absence of organic binders and the applied painting technique.
5
The study systematically characterized unique twelfth-century pre-Mongolian wall paintings from the Christ’s Transfiguration Cathedral using complementary in situ and laboratory methods.
