  • Characterization of the wall painting from the Insulae XVII of the Roman Emona (Ljubljana, Slovenia) [Elektronski vir]
    Gutman, Maja, 1984- ...
    As a part of broader study of the Roman wall paintings in Slovenia, the wall paintings from the Roman colony Emona (Ljubljana, Slovenia) have been characterized. In order to determine technology of ... executing wall paintings and provenance of the materials, type of pigments, aggregate and binder of mortar layers have been identified. In the paper, we present interesting fragments found in the so called Insulae XVII, room 50, in 1963. Only the lower part of the wall painting was preserved, containing a painted decorationof medallions with green and pale ochre circles connected with rhomboid fields. The wall painting is dated to the 2 nd half of 1 st century. The room it was in may had been a receiving hall or living room of fairly large dimensions, next to the central courtyard or porticus. The wall paintingfragment s with preserved original layers of mortar was lifted in 1963and then reinforced with wooden laths and gypsum mortar on the back side. In time, however, the frame collapsed, and in the process of conservation - restoration that begun in 2013 another red painted layer , possibly older, wasdetected and also sampled. Samples of pigments and mortar layers were analyzed using opti cal microscopy, Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy (SEM - EDS), FTIR microspectroscopy and Raman microspectroscopy. P igments such as red ochre, yellow ochre, green earth and black carbon were identified. According to the stratigraphic analysis most commonly one paint layer was applied, while details were painted using two paint layers. The wall painting was mainly executed in fresco technique. However, in some cases, especially for painting details, secco technique was us ed . Up to four preserved mortar layers were recognised that vary in their thickness and petrographic - mineralogical composition. Results showed that carbonate aggregate grains prevailed in upper mortar layers, followed by mixture of silicate and carbonate g rains in underlying layers . This contribution provides insight into the materials and techniques used in the Roman wall paintings and are therefore of crucial importance in recognizing the quality of such materials used in the Roman Empire, especially in s mallercolonies such as Emona. Results represent also an important contributionfor the current conservation - restoration interventions on Emona wall paintings.
