Popis: Wall paintings in the Roman period were used to decorate both public and private spaces
therefore, they reflect, on the one hand, ideas and convictions, and on the other, daily activities and socio-economic models. Characterizations of the pigments used in mural paintings are useful for determining the economic status of a specific settlement or the importance of a particular area or the buildings within it, since the cost of different pigments varied widely. Isotope analysis can be used to identify the provenance of pigments and to establish whether the raw materials are local, regional, or imported. This provides very important information, as it might be related to both the quality and the cost of the pigments, which, in turn, might be indicators of the socio-economic status of the area in question. The present study examines the sulfur isotope ratios of the cinnabar used in Roman wall paintings sampled from the high-status Roman Domus of Casa d&rsquo
Avinyó
and compares them with the ratios of the analyzed geological ores sampled at various Spanish cinnabar/mercury mines. The results exclude the possibility of the cinnabar being imported from outside the Iberian Peninsula. An isotopic analysis also suggested a few possible sources for the pigments.
