Integrated non-destructive geophysical methods to study stone masonry walls in historical buildings: tests on laboratory-scale models

Rita DEIANA / Maria Rosa VALLUZZI (Dipartimento dei Beni Culturali: archeologia, storia dell’arte, del cinema e della musica, Università degli Studi di Padova, Padova, Italy) Abstract: Cultural heritage diagnostics, particularly for historical buildings built with stone masonry, often represents  a problem in terms of structural analysis and consequently of proper restoration. Indeed, although the construction system is often apparently known and easy to identify, the complex form of walls or the more general presence within their internal structure of non-homogeneous and anisotropic materials, creates significant problems for their study. In this work we present the results of tests carried out with non-destructive integrated geophysical methods (ground penetrating radar, electrical resistivity tomography, sonic and seismic measurements) on laboratory-reconstructed examples of common stone masonry walls, in order to study three different static conditions. Generally, the decision about the use of a particular geophysical method depends on several factors, including: physical properties of the target and its surroundings, depth of investigation, resolution, and finally logistical conditions. On the other hand the choice of adequate acquisition parameters and the use of special devices to save the integrity of the wall surface represent important aspects in cultural heritage where the collection of meaningful information and the preservation are both important objectives. In this work we show the benefits of the use of integrated geophysical methods and the intrinsic limitations, discussing what are the unsolved and solvable questions in this field. Keywords: geophysical methods, non-destructive tests, historical building, stone masonry...

Collections of vedute – Preserving the historic heritage of the Transylvanian cities

Iulia CIANGA (Babes Bolyai University, Faculty of Geography, Cluj-Naoca, Romania) Abstract: “Veduta”, distinguished itself as an artistic style in the 17th century, due the influence of the Venetian School of Painting from Italy, and, become also well-known in Transylvania, region of nowadays Romania, representing a beneficial Eastern spatial extension of the Renaissance and Age of Enlightenment. The vedute representations contain relevant details regarding local conditions of living, geographic position, city walls, or the structure and colors of the buildings, some of them missing today. These details compared with the present situation, outlined in a vedutist manner by the author, can lead to a retrospective study over the physiognomy of Transylvanian urban landscape. Transylvanian urban paintings and engravings are found well preserved in collections such as: “Gheorghe Sion” at the „Lucian Blaga” Central University Library in Cluj-Napoca, “The Cabinet of Print Works and Drawings” in Sibiu or museums of art from Transylvania. The illustrations of the main fortresses, castles or monuments in Transylvania compose a very complex image of this controversial land beyond the forests (Trans=beyond, Silva=forest), in its attempt to preserve its historical and architectural landmarks. In my research project I wish to highlight the importance of the urban view, veduta, as a source of information with a great documentary value. It’s important to complete the historical data from a different perspective, compared to the written manuscripts, namely, from the perspective of the image creator. Its artistic and documentary value, which gives the possibility of learning the history of the cities may lead to the individualization of a cultural tourism, of specialized knowledge, but it may also lead to a tourism meant for the general public, having a virtual characteristic, of an open source type.

Senigallia Urban Archaeological Project: discovery, protection and musealization of a Sanctuary of the first Roman colonists during urban works in progress

Federica BOSCHI / Francesco BELFIORI / Giuseppe LEPORE (Department of Archaeology, University of Bologna, Ravenna, Italy) Abstract: In the context of the Senigallia Urban Archaeological Project, started in 2010 by an agreement between the Department of Archaeology of Bologna University, the Municipality of Senigallia and the Soprintendenza per i Beni Archeologici delle Marche, at the end of 2011 an important operation of archaeology was carried out in an urbanized space where building works were in progress for the realization of a new housing complex with underground garages. The procedure has contemplated a georadar survey of the whole area, which revealed some interesting reflections at a considerable depth. The following excavations were subjected to a constant archaeological monitoring, revealing a situation of extraordinary importance. In fact, the investigation has discovered a sacred complex probably founded by the first Roman colonists at the beginning of the 3th century B.C., and the remains of the Roman urban walls. Stratigraphy and pottery analysis allows us to reconstruct the history of this relevant sector of the ancient urban landscape. In a first time, the sanctuary was sub divo and extra moenia with rituals organized all around votive stones. In a second phase two sacella were build up, probably at the same time of the city wall construction, making urban the sanctuary. Despite this important discovery, a new procedure, agreed with all the subjects involved, allowed the building works to go on: roman ruins were disassembled and reassembled in a deeper level with a designed technique, enriching the modern construction with a musealization project and representing an example of compatibility between the needs of the modern city and the protection and valorization of its archaeological heritage. Thus, new precious data have been acquired, in particular about the foundation of Sena Gallica: the sacella were probably dedicated to Feronia and Fortuna goods, related to the Romanization and the water, and their orientation reflect the primary Roman urban plan.

New technologies for the enhancement of Cultural Heritage. Remarks on a new research protocol for urban areas, both abandoned (Suasa, Italy; Burnum, Croatia) and still inhabited

Julian BOGDANI / Enrico GIORGI (University of Bologna, Italy) Abstract: Since several years we have been involved in different research projects of the Department of Archeology of the University of Bologna, focused on archaeology (excavations and research), topography (photogrammetry and laser scanning) and remote sensing (satellite and aerial photographs, geophysics, etc.) in ancient centres of the middle Adriatic area, such as Suasa (Ancona, Italy) and Burnum (Šibenik, Croatia). Since both archaeological sites are inside naturalistic and archaeological parks, the research data, collected through innovative technologies and managed in integrated GIS platforms, were also used for wider projects of development and enhancement of the Cultural Heritage, with specific interest in cultural tourism. For this reason, particular attention was drawn to the 3D reconstructions of the ancient landscape, using computer modeling and traditional hand-made drawings. Web technologies and augmented reality were used in some cases to create full immersive experiences; it is the case of the Forum of Suasa, that can be admired in it’s Roman Imperial aspect using a web application. This complex approach to Archeological Heritage, combining specialistic research interest, use and experimentation of new technologies and attention to valorization and cultural tourism, will soon be applied to a new site, Ascoli Piceno, that presents some specific issues related to urban archaeology, due to the fact that the city has been uninterruptedly inhabited from Roman times to nowadays.

AFOA – Working group of freelance anthropologists

C. BERSZIN / B. JUNGKLAUS / I. TRAUTMANN (Gesellschaft für Anthropologie (GfA), Germany) Abstract: The recent restructuring of the field of anthropology within the university framework in Germany has led to the development of a new field of occupation: freelance anthropologists now frequently carry out the analysis of human skeletal remains from archaeological excavations in cooperation with state offices for archaeology, private excavation firms, or museums. The main focus of work is centered on the examination of human skeletal finds and cremated remains. The designation “anthropologist” is very broad and not protected. To ensure a high quality of analyses and protect the interest of freelance anthropologist, a group of experienced anthropologists founded the Workgroup “Freelance Anthropologists (AFOA)” at the 2011 meeting of the Society for Anthropology (GfA) in Schleswig. The members of AFOA have agreed upon guidelines and a codex in which they agree to adhere to the code of best practice and to deliver the highest standard of analyses according to current research standards. This codex ensures a high quality for serious anthropological work. With their signatures, members agree to abide by the guidelines and the codex. For more information on AFOA, its members and the codex, please visit the GfA website, http://www.gfanet.de/node/70, or contact the group speakers.
