The long-term monitoring of ancient wall paintings in historical monuments aims to assess the processes of decay involved, clarify the causes, permit plans of intervention and at the same time control the effectiveness of the restoration works. The paintings are prone to degradation over time. Their decay can arise from humidity, heat transfer, ultraviolet radiation, atmospheric pollutants, microbial agents, bad display or storage conditions, and even physical vibrations. This paper proposes a procedure for analyzing the state of preservation of the frescoes, which also takes into account...

This paper presents some preliminary results of the scientific investigations carried out at underground water channels located on Mounts Nebrodi in Sicily (Southern Italy). We performed several geophysical surveys as well as geomatics approaches were used in order to reconstruct 2D and 3D digital models of this underground monuments. n here, we also present the potential of valorizing these cultural heritage sites and its underground structures by the means of advanced technologies and digital reconstructions.

This paper presents the results of scientific investigations carried out at the Batia Church which is located in the small village of Tortorici (Messina, Sicily, Italy). We performed several geophysical surveys, as well as geomatics approaches, were used in order to reconstruct 2D and 3D digital models of the monument mainly using digital photogrammetry. Previous geophysical investigations have shown the presence of a crypt which was ultimately surveyed and digitally reconstructed. Here, we present the potential of valorizing the site and its underground structures by the means of advanced...

This study presents the results of a Ground Penetrating Radar (GPR) investigation combined with a photogrammetric survey of a small archaeological site in Rabat, Malta. The investigation was conducted in preparation for small but challenging road infrastructure works in view of the surrounding archaeologically rich landscape. This area is characterized by a significant concentration of Punico-Roman tombs and more extensive hypogea datable to the Late Roman and Byzantine periods. GPR survey shows anomalies in the form of elongated patterns, some of which aligned to a number of blocked...

The aim of the work is to describe experiences in the field of the survey of cultural heritage with the use of Terrestrial Laser Scanner and terrestrial and UAV photogrammetry. In particular, using the latest technologies, the work describes a methodology and survey techniques capable of producing 2D and 3D models suitable for subsequent restoration or maintenance work. The case study taken into consideration concern the Royal Racconigi Castle (Italy).

The paper presents the development of a Virtual Reality application to perform dives in the Christoforos Shipwreck. The huge wreck lies in the Panormos Bay of the Skopelos island (Greece) at a depth of 45 meters. Based on a well-known methodology designed for ancient shipwrecks, the 3D reconstruction of the underwater site has been carried out by adjusting the workflow to survey modern shipwrecks. In particular, the methodology, based on photogrammetry, is capable to provide a highly detailed 3D reconstruction of the shipwreck in few dives, considering issues like working depth, elevations,...

Active thermography of panel paintings can retrieve useful information about the support and the preparation layer behind the pictorial one. The main challenges are obtaining such information by using low power excitation to avoid any possible alteration of the painting and processing it to gain insight about the stratigraphy of the artwork. Pseudo-noise active pulse compression thermography in combination with timeand frequency- domain analysis was used here to face these challenges. The procedure was applied to a panel painting from Raffaellino del Colle, a former Raffaello’s pupil, owned...

The cartographic unification of the Italian peninsula with the Carta Topografica d’Italia used the important work done during the pre-unification period and the last years of the XIX century. After the territorial unity of 1870 (leaving aside the appendix of the unredeemed lands of the north-east annexed after the Great War), the vision of a wider space for movement and citizenship took shape. For this reason, it is important to guard the memory and safeguard of all trigonometric points, like geodetic base lines, witnessing in the country the long and hard measurement work.

Natural ultramarine has been one of the most precious blue pigments employed in the past in the artifacts. It is typically obtained by crushing and grinding the lapis lazuli rock and selectively extracting the blue mineral lazurite. Since the early 19th century, when the synthetic version was produced, the use of this much less expensive material became widespread, and synthetic ultramarine blue replaced the natural one in painting palettes. The present study is conducted as a preliminary μ-Raman investigation for creating a comprehensive and detailed database of the ultramarine pigments,...

The natural radioactivity content in twenty samples of four different typologies of earth pigments (Raw Sienna, Burnt Sienna, Raw Umber, and Burnt Umber) was investigated through High Purity Germanium (HPGe) gamma spectrometry, with the aim of evaluating the background levels of natural radioactivity in the analyzed samples, and of assessing the radiological health risks due to the external exposure to the enquired earth pigments, by calculating the absorbed dose rate and, starting from it, the annual effective dose equivalent. Finally, the obtained results gave a promising contribution in...
