3D resistivity anomaly probability tomography at the archaeological site of Sagalassos (Turkey)

The archaeological site of Sagalassos is a very important settlement located in a magnificent mountain landscape, 7 km north from a little village named Aglasun (province of Burdur, SW Turkey). Since 1990 the University of Leuven (Belgium) carry out an interdisciplinary archaeological research programme that study the uninterrupted occupation of more than 1000 years in all its aspects from daily life to architecture, from trade and its mechanisms to environmental conditions of the past. The ancient roman city is a site covered under erosion layers and preserved many secrets that need to be revealed. A geophysical campaign was planned along the south facing terraces of the mountain slopes, in order to highlighting the structure of the city still covered. Site conditions (high slope, high grass, several obstacles) and the need to investigate high depths led to the choice of the most suitable geophysical methods. Particularly a 3D distribution in the subsoil of resistivity tensor probability was esteemed.

Investigations on provenance and content of archaic transport amphorae from Castello di Alceste (S.Vito dei Normanni-Br) by chemical analyses through XRF/FP and GC-MS

The aim of this work was to determine the provenance and the content of a group of archaic transport amphorae of different typologies retrieved during the archaeological excavations in the archaic settlement of Castello di Alceste (S.Vito dei Normanni- Br). We analysed a group of 16 samples belonging mainly to "Corinthian B" amphorae, which are widely diffused in the western Mediterranean basin and in Greece, but whose geographical provenance is still under discussion. XRF/FP analyses revealed that the amphorae were manufactured in three different areas of the Mediterranean: southern Italy, Ionian Islands and Corinth. GC-MS analyses revealed that most of the amphorae contained wine markers, together with pine resin, probably used as a sealant for the vessel or an additive to preserve wine. The contemporary presence of oil or animal fats in some containers suggests a possible reuse of the amphorae to store and preserve other foodstuffs.

Archaeometry and urban archaeology: the case study of Sant'Agata la Vetere church (Catania, Sicily)

The church of Sant'Agata la Vetere in Catania is located in a complex area of urban stratification and, according to historical sources, it is considered the first cathedral of the city. The occasion of archaeological excavations in the area of Sant’Agata la Vetere yielded many finds. Among these, frescoes, fragments of glass and mosaic tiles were dated, on an archaeological basis, to the 3rd and 4th centuries BC. The aim of the present work is to provide a scientific contribution to the archaeological classification of the site through the characterization of the finds from a compositional and colorimetric points of view in order to gain insight about their manufacture. The different kinds of finds called for combined non-destructive methodologies for having complete and expanded information. The techniques employed were XRF for the compositional investigation and visible spectrophotometry for the colorimetric analysis coupled with the Raman spectrometry for pigment identification.

Measure for participatory valorization of Cultural Heritage

The Italian territory is characterized by an extremely high number of Cultural goods. Knowledge and measurement of many of these Cultural Heritage is extremely difficult in relation to the complexity of surveys through traditional methodologies. The contribution proposes an original approach to the knowledge and measurement of Cultural Heritage based on a social approach, transforming the user as an actor of the procedures for the acquisition of raw data. The Heritage Go (HeGo) project is the platform for data acquisition and processing. The contribution, in addition to a description of the project, describes the first experiments focusing on the metric quality of the models obtained with SfM methodologies from raw data acquired by users.

Characterization and provenance of ancient gemstones: Case study of a gold-and-sapphire jewel dating from the Roman imperial period and found in a tomb in Colonna, Italy

In 2011, an extraordinary piece of gold jewelry set with precious stones was found in a woman's tomb discovered not far from Rome and dating from the third century AD. Our examination and archaeometric analyses enabled us to identify the technique used to make the jewel and to characterize the nature and provenance of the gemstones. The analyses showed that all the stones were natural sapphires. Their inclusions and gemmological features indicate that they came from southern and southeastern Asia, thus gaining insights about trade routes and the luxury-goods market during the Roman imperial period.
