“…The µEDXRF data confirmed that Fe prevails in these areas (Table 1), so other possible sources for this shade were discarded. This combination of hematite and amorphous carbon has been found not only in the decoration of Roman contexts 47 but also, for example, in Etruscan tombs 48 and in Egyptian tombs of the 2nd ct. a.D. 49 .…”

Wall paintings have become one of the most relevant, complex and challenging research subjects in Archaeometry. Minimally-or non-invasive, accurate and multidisciplinary methods are needed to successfully address the problems posed by their physical and chemical properties and by their analysis techniques. Specifically, the analytical method implemented for the study of this type of samples must enable a precise separation of the chemical information from backgrounds and scenes, allowing the identification of pigment's components in overlapping layers, the detection of minority components and the elucidation of pigment mixtures. thus, this paper puts forward a multidisciplinary approach towards these goals by means of the combined use of micro energy Dispersive X-ray fluorescence (µeDXRf) surface mapping and single-spot micro-Raman spectroscopy and µeDXRf analysis. the samples under research come from the site of cástulo (Linares, Spain), one of the most important Roman cities in the iberian peninsula. it must be emphasized the uniqueness of the walls of Cástulo, their optimal conservation state and the richness and variety of the colour's palette used in their decoration, which make them an excellent and representative example of Roman wall paintings. The Roman immovable and movable heritage of Europe is outstanding not only in terms of quantity but also of quality. As a research subject, it pursues both historical reconstruction and the design of preservation and restoration strategies and diagnostic procedures. It is, thus, a major area of development for archaeometric analysis, especially as regards spectroscopy. Wall paintings are particularly remarkable in this regard. A major component in the decoration of public and private buildings, it is one of the most attractive heritage goods of museums and sites. Research on wall paintings and on their preservation is a source of archaeometric projects intended to retrieve as much information as possible with the least possible alteration or damage to such rich and invaluable decoration. Wall paintings have typically been researched based on simple decorative patterns or on single-spot analysis of samples, sometimes amounting to just a few. In most cases, the aim was the identification of the pigments and the binders used 1-4 , a better knowledge of how the paintings were made 5-7 , and proper understanding of the processes that may damage the painted surfaces 8-11. The results obtained are often under the influence of the specific properties of the paint layers, of the raw materials used and of the limitations of the analytical techniques used. This paper therefore sets out to put forward and test a chemical analysis procedure for general use in research on wall paintings. The paper relies on research on a wide gamut of colours, on a significant number of samples, and on the experience gained from addressing a range of difficulties found for the use of certain techniques and posed by the properties of the pigments under research. Methodological improvements are ma...
