“…Navas et al applied PCA analysis on first‐derivative Raman spectra to investigate historical tempera paint model samples. Using Raman data on the pigments, Siotto et al tried a virtual reconstruction of the ancient polychromy on a digital 3D model of the sarcophagus dedicated to Ulpia Domnina (National Roman Museum in Rome). Several examples of nondestructive analysis of painted layers on sculptures and plasters using spatially offset Raman spectroscopy have been presented by Conti et al(Fig.…”

Minerals, as raw structural materials or pigments, play a fundamental role in archaeometry, for the understanding of nature, structure and status of an artefact or object of interest for cultural heritage. A detailed knowledge of the mineral phases is crucial to solve archaeological problems: Raman spectroscopy is a powerful investigation technique and has been applied extensively in the last 30 years on mineral identification and on pigment degradation. Here we report an updated review, covering the last decade, of the applications of Raman techniques to issues in which raw minerals, including mineral pigments, are involved. Particular attention is devoted to cases where the Raman analysis of minerals is deeper than a simple identification of the phases present in an archaeological or artistic object.

“…In other Roman sarcophagi analyzed by the authors [23,24], yellow ochre was found as a priming layer for the gold leaf of the cupids' bracelets. Other scholars also describe the use of iron oxides and hydroxides either mixed or not with other materials, as a preparation layer for gilding [49,50]. In the case of the Lot Sarcophagus, no traces of gold were found.…”

The Lot Sarcophagus is one of the most relevant funerary sculptures of late antiquity (mid-4th century AC). Some of the remarkable aspects are the following (i) it is still preserved in situ; (ii) most of the carved scenes are rarities or unicum; (iii) not all the sculpture work has been completed, which allows us to analyse the executive process; (iv) many traces of polychromy have remained. This paper is focused on the characterization of the residual polychromy by using in-situ non-invasive techniques. Furthermore, few micro samples were taken, to be analysed in laboratory to study the composition of some deposits and to define if a preparatory layer was present under the coloured layer. The data showed that the very rich polychromy of the Lot Sarcophagus was made of Egyptian blue, yellow ochre, and three different types of red: two inorganics (red ochre and cinnabar), and one organic-based (madder lake). Furthermore, some decorations, completely vanished and no longer visible to the naked eye, have been rediscovered, also providing details on the construction phases. During the project, the 3D model of the sarcophagus was acquired, which afterwards was used to map the results of the diagnostic campaign.

“…Specific training in the operation of the scanners and a more careful planning of the capturing process is required, due to the complexity of the set up time and safety issues related to using a laser. A number of researchers have used MeshLab software to align the different scans taken from the different parts of the object of interest [7][8][9]. As with the photographic 3D reconstruction software solutions, MeshLab does not provide any statistical values to indicate the precision or accuracy of the alignment of the point clouds.…”

“…A number of publications [7][8][9] have examined the combination of using laser scanners and images, however these projects only used images to colour the point cloud rather than for 3D reconstruction. Compared to the use of images, the use of laser scanners requires more equipment and software.…”

Pilbara rock art: laser scanning, photogrammetry and 3D photographic reconstruction as heritage management tools

et al. 2017

Recording techniques such as laser scanning, photogrammetry and photographic reconstruction are not new to archaeology. However as technology evolves and becomes more readily available such methods are being more regularly employed within a cultural heritage management context, often by people with little experience in using these technologies for heritage applications. For most cultural heritage management practitioners, the awe and lure of technology and the ease with which it can bring archaeology to life can distract from the end game of managing the site on the ground. This paper examines the advantages and disadvantages of laser scanning, photogrammetry and photographic reconstruction in recording, managing and interpreting rock art sites with an emphasis on its practical applications to the field of heritage management. Using a case study from West Angelas in the East Pilbara region of Western Australia, we will examine how these technologies assist in the practical management of heritage sites, and the significant outputs achieved for Aboriginal stakeholder groups in remote access to, and the interpretation of indigenous heritage sites.
