Avtorstvo stenskih poslikav, pripisanih Janezu Aquili, na osnovi materialne karakterizacije ometov in slikarskih tehnik ; Authorship of Wall Paintings Attributed to Johannes Aquila on the Basis of Material Characterization of Plasters and Painting Techniques

Johannes Aquila is well known for his mural paintings from around 1400 in Velemér (Hungary), Turnišče and Martjanci (Slovenia), Bad Radkersburg and Fürstenfeld (Austria). In this research, materials and painting techniques used by him and his workshop were studied, applying differnet invasive and non-invasive techniques (OM, SEM-EDX, FTIR, XRD, XRF, VIS). Obtained results revealed a huge difference in the quality of technical execution between his early murals and his latter ones, where most of the work was carried out by his disciples.
