Traces of Polychromies in Roman sculpture: a multi-analytical approach

Recently, some museums started seeing in a new light their collections and searching for overlooked traces of painted colours: one example is the National Archaeological Museum of Aquileia, nowadays in north-eastern Italy, a Roman city close to the Adriatic Sea.
Among the sculptures with an easily recognizable polychromy, five were chosen (three statues, a funerary relief and a fragment of architectural decoration), in order to give new and unpublished information about the colours on marble and stone of the Roman Aquileia between the 1st century BC and the 3rd century CE, with the support of a multi-analytical approach (imaging, FORS, Raman and microsamples).

Analyzing an Ancient City: Non-invasive Studies of Ostia Antica Archeological Park s Wall Paintings

Roman wall paintings at the archeological site of Ostia Antica dating from the 1st century BCE to the 4th century CE were studied in an integrated non-invasive approach using portable instrumentation, namely: Nuclear Magnetic Resonance (NMR), Hyperspectral Imaging (HSI), X-Ray Fluorescence (XRF), Visible Induced Luminescence (VIL), External Reflectance Fourier-Transformed Infrared Spectroscopy (ER-FTIR), Raman and Near Infrared (NIR) Spectroscopies. The objective of this study is threefold: to investigate the materials and techniques of wall paintings at Ostia Antica in order to gain insight into the evolution of the use of materials and painting techniques over time, the testing of novel instrumentation in archeological contexts such as portable HSI and the recently developed NMR hardware and stratigraphy protocols, as well as to aid in the conservation efforts at the site by providing information on the material composition of the walls. Some of the main results of four campaigns dating 2019-2023 are presented.

Metaverse(s) and Cultural Heritage: overview and perspectives of the Italian scenario

The paper sketches an overview of the current italian situation in relation to the concept of metaverse describing the spreading enterprises in terms of platforms, tools and knowledge leveraged . At the same time, the perspectives of such initiatives (and of the metaverse itself, as final goal of a long-lasting dream in human story) are discussed.

Extended BIM: a proposed workflow for the integration of the HBIM and EM approaches

The present research proposes the beta version of a collaborative workflow which aims at linking HBIM and Extended Matrix using Open-Source coding and visualisation tools. The developed workflow was tested on a significant case study, the Roman Theatre of Terracina, whose excavation works started in 2019 and were initially documented through an integrated TLS and UAV digital survey. In 2021 and 2022 the excavation data were updated, also using SLAM technology, thus the proposed approach focuses on the systematisation of the analysis and processing of the data regarding the consecutively surveyed excavation phases.

HBIM for restoration project and data management of a religious complex

The paper presents the first results of a research project aimed at digitizing the restoration process of the monastic complex of Santa Maria a Graiano, located in Fontecchio (AQ). The parametric model allows the management of heterogeneous data derived from multidisciplinary knowledge processes and facilitates data sharing. The representative modelling of the artefact after the damage caused by the 2009 earthquake, to which the planned restoration operations were linked, compared to the parametric model of the artefact after restoration, allowed cooperation between different professionals, in addition to the documentation of the work carried out. In this way, the model assumes a central role in the knowledge process but also the heritage management process as it facilitates the choice of conservation strategies to be implemented on the asset in future years and to preserve the memory of the interventions carried out, simplifying the maintenance process in the as-built phase.

Dynamic 3D model for decoding archaeological complexity of funerary contexts

Archaeological contexts are extremely dynamic, undergoing changes over time that profoundly alter the archaeological record, both due to intentional human manipulation and natural degradation phenomena. These post-depositional phenomena distort our perception of ancient contexts, often making it difficult to recognize the original arrangement and to understand what the archaeologist is analyzing. This aspect especially concerns the funerary contexts, like burials, which are subject to numerous natural or anthropogenic changes. This study shows how, by analyzing funerary contexts in a processual key and reconstructing them in a 3D environment, it is possible to simulate, to isolate, and to analyze post-depositional phenomena through metrically and morphologically correct 3D reconstructions. 3D simulation can be extremely accurate when parameters such as gravitational force is taken into account. The aim is to verify changes due to transformation phenomena. The goal is to create a sequence that shows the transformative processes of the burial, from the moment of deposition to the excavation phase.

Dimensional assessment in bioarchaeology applications: a preliminary study on quality controls in 3D printing of human skulls

In the last few years, 3D printing has been used in archaeology and cultural heritage fields for different purposes, i.e., research, conservation and access to museum exhibitions. Among the different technologies of 3D printing, e.g., stereolithography or selective laser sintering, this study focuses on the quality assessment of printed models using fused deposition modeling technology. To simulate an anatomical archaeological find, a cranial model assumed as a gold standard has been printed from computed tomography (CT) data of a human skull. Eight 3D printed (3DP) models have been reproduced and CT scanned with the same protocol in order to quantify their congruence with the gold standard through an objective measurement method based on image analysis. Preliminary results show an increasing percentage error as the degree of model detail increases, from 1% to 15%. The experimental results are discussed and commented also from a metrological point of view.

3D virtual restoration: from photogrammetric and 3D modeling techniques to integration with scientific documentation in a GIS environment

The contribution proposed here is linked to the doctoral research being carried out, which aims to develop a 3D GIS (Geographic Information System) platform that can integrate all the software necessary for the elaboration of a scientifically correct virtual restoration and at the same time can contain all the documentation relating to the intervention itself, the analyses carried out and the sources used. The contribution, therefore, will focus only on the specific case of the 3D virtual restoration of artefacts starting from the data coming from one of the case studies investigated, specifically a kotyle from the Etruscan excavation conducted, by the University of Tuscia, in the Monte Abatone necropolis in 2019, to show the potential of this project and possible further developments.

Satellite automatic extraction and characterization of looting features in the Peruvian desert

Archaeological looting is a known threat and causes irreversible damage to historical heritage. In Perù, looting of the grave robbers is a diffuse and ancient problem, starting in the first centuries of the Spanish colonization: the search for gold of the Conquistadores. The desert areas of the Peruvian southern and central coast are the most affected by the relentless plundering of archaeological sites. To counter this scourge, in recent years, many studies succeeded in monitoring the archaeological contexts via satellite remote sensing and automatic digital workflows. In this paper we propose a further step of these studies, with the presentation of an automatic workflow to extract and classify the superimposed looting pits of heavily disturbed sites, establishing a relative chronology of the illegal activities.

Multiple GPR surveys in urban area. The case of S. Giovanni in Laterano and S. Croce in Gerusalemme, as part of ERC Rome Transformed Project

The geophysical prospection is generally considered as the attempt to locate structures of archaeological interest buried in the natural subsoil, but in many cases, when applied in urban centers, this attempt could file due to the effect and disturbances caused by recent man-made structures in the subsoil, covering any signal related to possible archaeological structures. In the present paper the GPR surveys carried out in two urban archaeological sites in Roma, characterised by different targets and environmental conditions, are presented and discussed.
