Within a research project aimed at the study of the archaeological context of the Basilica Julia in the Roman Forum and the reconstruction of the transformation phases of the building, different techniques of geophysical prospecting were performed. In particular, GPR and ERT surveys were carried out and allowed for the acquisition of interesting data on the foundations of the Basilica Julia, built during the late Republican period and rebuilt at the beginning of the Imperial age, and on the buried remains of the previous Basilica Sempronia, built in the 2nd cent. BC in the same area....

As part of the project called SAET, of which the Institute for Archaeological and Monumental Heritage (CNR) is a partner, geophysical surveys have been carried out with the aim of identifying structures of archaeological interest that may be present within the investigated area. The GPR Sir 3000 from GSSI was used, equipped with 270 and 400 MHz antennas, the Ris Hi mod equipped with 200-600MHz dual band antenna, the syscal kid georesistimeter with 24 active channels and the bartington Grad 601 Gradiometer were used for geophysical surveys.

GPR surveys were carried out in the Baroque Cathedral of Lecce and in its crypt built in the 12th cent. and transformed in the 16th and 17th centuries. The investigations highlighted the presence of many unknown structures under the floor of the church. Some of them could be belong to the previous building of the Romanesque period, while most of the anomalies are related to tombs and underground chambers (ossuaries) located under the floor of the Baroque church. Moreover, six tombs of the 19th and 20th centuries and other ancient structures were documented under the crypt floor.

To verify the provenances of limestones that were used for construction and restoration of the Batalha Monastery, limestone quarries in central Portugal were investigated. Samples were collected from quarries and monastery in field investigation. The elements-alignment of calcium and strontium based on XRF result has suggested the source of fragments from different parts the monastery. Observation of the thin sections has supplemented petrographic evidence for this identification. XRD, TGA were also used for acquiring mineral information and chemical composition of the stones. This origin...

This work is part of a research project titled MaTaCoS (Advanced materials and technologies applied to the conservation of underwater cultural heritage) funded by the Italian Ministry of Economic Development (MISE), concerning development of innovative tools and methods for the protection of Underwater Cultural Heritage, with particular regard to cleaning and consolidating procedures to be carry out directly in situ. The fishpond of the archaeological site of Castrum Novum (Santa Marinella, Rome, Italy) was chosen as a pilot site for experimentation. Castrum Novum was a Roman colony whose...

The paper presents the results of two different approaches applied to the newly-restored painting The Conversion of St Paul, the main altarpiece in the Cathedral of Mdina in Malta. This large, dramatic painting is work of the Baroque artist Mattia Preti, il Cavaliere Calabrese. As is normal with a professionally executed restoration, several scientific methods have been used before, during and at completion, in the framework of a global analytical strategy. In particular, we focus on the results of the digital photogrammetric survey which uses imagebased approaches for 2D/3D models...

The results of Multi-slice X-ray Computed Tomography (MSCT) and Surface-Enhanced Raman Scattering (SERS) study performed on representative organic and inorganic ancient pigments painted on wooden support are presented and discussed. Clear Raman spectra were acquired for organic pigments such as a madder lake, overcoming their fluorescence and weak Raman scattering drawbacks. MSCT Hounsfield Units (HU) measurements show the ability to differentiate the materials, building a volumetric view and, with appropriate algorithms, to segment the layers of the specimen using suitable reconstructions....

In this work we present a novel relative humidity sensor of low invasiveness and visibility, well suited for applications in cultural heritage and in particular to monitor the moisture content in stone and wooden artworks. The sensor is based on fibre optic technology, produced by depositing a thin coating of a hygroscopic material on a thin and transparent, barely visible, fibre optic. The novelty of the projected sensor is in the proposed hygroscopic material, which is a mixture of Agar and Chitosan. This material overcomes the critical issues of sensors previously described, based on the...

For centuries, the architecture of the Romanian monuments reflected the highest standard of European architecture, many masonry buildings had used bricks, wood, roof tiles and various mortars. However, the characterization of the construction materials is prioritized for obtaining informations about the raw materials, building technology and the history of previous restorations. Under such context, in this paper, three types of materials were collected for analysis from the Corvins Castle circular towers: Deserted Tower, Drummers Tower and Mace Tower. The structural, compositional and...

Laser Induced Fluorescence (LIF) is a wellrecognized spectroscopic technique for non-destructive surface chemical analysis. It is particularly suitable for in situ analysis on delicate targets as artworks, because it does not need any sample preparation nor contact, working remotely also where only optical access is available. Hyperspectral systems have the advantage to provide whole spectra of the analysed point, and thanks to motorized optics can produce fluorescence images and map of surfaces. Since the early 2000s ENEA has developed hyperspectral LIF scanning systems. To shorten...
