This paper shows the benefit of using the aforementioned tools to study the peculiar clay mask No. 11114-E, discovered in 1973 in the Greek necropolis of Lipára, inside tomb No. 1558. The specimen, now exhibited in the Classical Section of the Aeolian Museum, is considered unique both in the Aeolian Islands and in the ancient Greek world, as it is the only one merging two half faces attributable to different characters. This feature, unknown at the time of discovery, has been highlighted in 2018, thanks to a restoration intervention by which a hard concretion layer covering a large portion of the mask surface was removed, bringing to light a smiling young half-face next to an old one with Silenic features. In 2019, the mask was surveyed in situ through a portable and performing laser-scanner arm (the QuantumTM FaroArm by FARO) to produce a high-resolution 3D model useful to enhance the reading of the two halves (not evident enough, due to its state of preservation). The data processing was performed using the Geomagic Wrap software, able to align and merge multiple scans into a single model and to export results in multiple formats, easily shareable and viewable in free software or via the web. Finally, thanks to this method, the successful generation of a digital replica was performed; the resulting replica is useful for dissemination and as a support for the hypothetical reconstruction of the two prototypes taken as models by the craftsman who created the mask.Highlights:A 'mobile laboratory’ consisting of portable equipment has been set up to perform 3D metric surveys on a selection of artefacts preserved at the Museum of Lipari.By means of an ultra-precision laser-scanner arm, a 3D survey on a miniaturistic double-faced mask, belonging to the classical theatrical terracotta, has been performed.A geometrically accurate and realistic 3D final model has been created. This helped the study and reconstruction of the two characters composing the mask.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44623198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its cemetery, outside the walls, presents an extraordinary Byzantine necropolis, where 163 hypogea graves were documented, thanks to recent archaeological campaigns financed by the Ministry of Culture (“PAMES-Sirio Euphrates Middle Archaeological Project”). This paper presents the research for obtaining 3D models of graves, selected in the cemetery, by combining information (obtained from planimetric and photographic surveys of the site) with taxonomic features (types of arcosolia, vaults, accesses, stairways...). The 3D modelling process is carried out using data collected during the survey of the graves. These data are then used to restore the surfaces which cover the burial chambers dug out in the ground. The modelling technique was based on generating surfaces, incorporating the different sections and profiles obtained during the data collection phase. The surfaces generated enclose the volume of the dug-out space so that the definitive grave models were obtained using a simple Boolean operation, removing these volumes from a prism-shaped piece representing a portion of the land, thus emptying the interior. The result has provided a reliable and rigorous graphic basis for the design and printing of 3D models, contributing to the dissemination of the exhibition called \"A retrospective on five years of archaeological activities in Syria\".","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46868820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Benito‐Calvo","doi":"10.4995/VAR.2021.13742","DOIUrl":"https://doi.org/10.4995/VAR.2021.13742","url":null,"abstract":"During the 19 th and 20 th centuries, numerous museums, scientific societies, and royal academies were founded in Europe and America. In this scenario, the Anthropological Museum Montane was founded in Havana, Cuba. Its collection has grown over the years, thanks to researchers, antiquarians, and amateurs. Since its foundation, the Museum Montane has become an essential institution for anthropological and archaeological research in the region. Nowadays, the Museum Montane, like other museums in developing countries, faces a challenge in the introduction of state-of-the-art technologies to digitizing exhibits and the creation of innovative projects to attract visitors. The current possibilities of virtualization of cultural heritage using digital technologies have a favorable impact on the preservation, access, and management of museum collections. The use of three-dimensional (3D) models fosters engagement with visitors, stimulates new forms of learning, and revalorizes the exhibits. In the current study, we use a hand-held structured light scanner to create 3D reality-based models of pre-Columbian crania from the Caribbean and South American collection of the Anthropological Museum Montane. The resulting 3D models were used for producing 3D printing replicas and animated videos. The 3D resources derived will encourage new knowledge through research, and provide broader access to these pre-Columbian crania collection through learning and outreach activities. The significance of digitizing these specimens goes beyond the creation of 3D models. It means protecting these fragile and valuable collections for future generations. The methodology and results reported here can be used in other museums with similar collections to digitally document, study, protect, and disseminate the archaeological heritage. Going forward, we seek to continue exploring the application of novel methods and digital techniques to the study of the pre-Columbian crania collections in Latin American and the Caribbean area. Highlights: A hand-held structured light scanner was used to acquire 3D reality-based models of pre-Columbian crania. The 3D models resulting were used for 3D printing replicas and 3D animations. This study provides unprecedented 3D reconstructions of pre-Columbian crania in the Caribbean area, and new 3D reconstructions of artificially deformed crania from South America. The 3D resources created will encourage new knowledge through research, and provide broader access to these pre-Columbian crania collection through learning and outreach activities.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70631637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starting from the idea that computers and the internet have drastically changed the world in the last decades, this paper advocates for the creation of a space where archaeologists from around the world can share information about maritime history and exchange data with colleagues. Following the principles of open access, we argue that the publication of raw data is necessary and significant for the development and democratization of the discipline. Below, we explain the fundamental aspects of the Nautical Archaeology Digital Library (NADL, https://nadl.tamu.edu/ ) and its efforts to standardize information collection for shipwrecks and related sites, so that scholars can create a community to disseminate both raw data and complete information in the field of maritime archaeology. To achieve this, our purpose is to contribute towards a common-ground methodology and terminology that promotes an intelligible dialogue within the global community of nautical archaeologists. This paper addresses some considerations on terminology and systematization in scientific disciplines and discusses the theoretical and methodological issues linked to the process of creating a template for recording shipwrecks. Furthermore, it discusses some of the problems related to the standardization of description processes and the necessity to create a flexible system that accounts for the diversity of the data. The third section discusses how science is greatly enhanced by the publication of information in open access platforms.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70631828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the occasion of the 175 th anniversary of the Praxedes Mateo Sagasta’s secondary school of Logrono (Spain) an exhibition about the history of the institution was organized at the premises of the Library of La Rioja. The current school building became operational in 1900 and was built on the former site of a Carmelite convent. It is noted that the existing rooms of the convent were the first location for the school, after the expropriations of religious communities during the mid-nineteen century. For the benefit of the aforementioned exhibition, it was deemed interesting to generate a three-dimensional (3D) virtual reconstruction of the buildings of the convent to show how it would have looked. However, the scarcity of the contemporary graphic information was a challenge, so it was decided to generate the virtual reconstruction from a paper craft model created by the librarian of the secondary school as a result of his research on this matter during the last years. This text describes the 3D modelling of that cut-out element by means of monoscopic photogrammetry (perspective drawing) and the use of non-realistic rendering based on the appearance of the paper mock-up (and not trying to recreate the real image of the buildings) so as to provide a suggestive view of the convent and create interactive exhibition items. Moreover, the text deals with the long-term preservation and the improvement of the re-use of the 3D models. The former by resorting to institutional repositories —from which users can download the full detailed versions— and the latter employing versions able to be visualized in 3D warehouses (such as Sketchfab ) and augmented reality (AR) applications.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70631643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A digital version of a mosaic can be useful for archaeologists, scholars and restorers who are interested in studying, comparing and preserving mosaics. Nowadays, archaeologists base their studies mainly on manual operation and visual observation that, although still fundamental, should be supported by the aid of automatized procedure of information extraction. In this context, this research intends to overcome manual and time-consuming procedure of mosaic tesserae drawing by proposing Mo.Se. (Mosaic Segmentation), an algorithm that exploits deep learning and image segmentation techniques; specifically, the methodology combines U-Net 3 Network with the Watershed algorithm. The final purpose is to define a workflow which establishes the steps to perform a robust segmentation and obtain a digital (vector) representation of a mosaic. The detailed approach is presented, and theoretical justifications are provided, building various connections with other models, making the workflow both theoretically valuable and practically scalable for medium or large datasets. The automatic segmentation process was tested with the high-resolution orthoimage of an ancient mosaic, realized following a close-range photogrammetry procedure. Our approach has been tested in the pavement of St. Stephen's Church in Umm ar-Rasas, a Jordan archaeological site, located 30 km southeast of the city of Madaba (Jordan). Experimental results show that this generalized framework yields good performances, obtaining higher accuracy compared with other state-of-the-art approaches. Mo.se. has been validated using publicly available datasets as a benchmark, demonstrating that the combination of learning-based methods with procedural ones enhances segmentation performance almost 10% in terms of overall accuracy. The ambition is to provide archaeologists with a tool for automatic extraction of geometric of ancient mosaics, which expedites their work.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70631821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite varied levels and visible gaps between rural and urban regions in terms of technology usage, innovative initiatives have been created, which correspond to the needs and expectations of a technology-savvy public. As a starting point, a number of public institutions dealing with tangible cultural heritage (e.g. museums, palaces, temples, World Heritage Sites (WHS)) do use innovative digital tools in order to communicate to various audiences, as well as to enrich visitors’ experience, especially taking into consideration young generations. This paper will firstly examine the role of ICTs in intangible cultural heritage (ICH) (e.g. Batik, Wayang puppet theatre, etc.); secondly, the authors will explain how ICTs can help to communicate and promote the values, history, and significances of ICH products, both for locals and tourists, with the goal of raising awareness on cultural identity. However, the knowledge of ICH still requires contacts with its own communities and is vulnerable, as it can be exposed to excessive cultural commoditization through e-platforms. This study aims at giving an overview and some examples of digital interventions for cultural heritage communication implemented by various stakeholders in Indonesia. In addition, this paper analyses to what extent a participatory approach engaging local communities, academics, private sectors, NGOs and the government, can ensure higher levels of effectiveness and efficiency, hence supporting the conservation of UNESCO tangible/ICH in Indonesia.

The intention is to improve the current museography of the monument, which poorly performs its main purpose: cultural heritage dissemination. Firstly, most of the grandstands and the main entrance are the results of a partial restoration carried out during the 1960s, based more on pragmatic rather than scientific criteria, and with many historical inaccuracies. Secondly, the worship complex, consisting of a sanctuary on the arena and another one down of, goes unnoticed by most visitors. Finally, the only area where the grandstands remain, and the only one where someone can understand the vaulted construction technique, it is not available for public entrance.Facing this situation, the present reconstruction proposal provides people with a useful tool to comprehend the Roman building, especially where the remains are poorly preserved or inaccurately restored. In this regard, a set of rendered images has been created and, by such means, people can compare the reconstruction of the Roman building with its current remains. For this purpose, scientific methods have been employed, as well as 3D modelling technologies. First and foremost, all publications relating to Tarraco’s amphitheater have been thoroughly reviewed. Then, the archaeological remains have been redrawn using CAD tools. Henceforth, the plans and sections have been reconstructed, 3D modelled and rendered.While the reconstruction was being developed, Roman ludic processions were found to be an interesting topic that could serve as a common thread. This way, the sectors to be reconstructed were sequenced as follows. First, the eastern entrance or Porta Triumphalis, which led the entourage to the arena. Second, the upper sacellum, where the priests conducted the liturgies to inaugurate the games. Third, the southern area, through which the gladiators and the authorities left the arena to their positions (for the first group, the service's rooms located in the underground, while for the second one, the authorities stand). Last but not least, the sanctuary under the arena, where the gladiators could perform their last prayers before the combat began.Along with the text below, images of the reconstruction can be found next to photographs of the state of preservation, following the aforementioned sequence. Therefore, Figures 2, 3 and 4 explain the image and functioning of the main entrance (Porta Triumphalis): while Figures 2 and 4 show virtual restorations from the inside and the outside, Figure 3 presents the development of the corridor in section and plan. Figures 6 and 7 display how the upper sanctuary had looked like from the arena and once inside respectively.

Archaeologists rarely find complete vases but, generally, damaged and in fragments, often mixed with other pottery groups. By using the traditional manual method, the analysis and reconstruction of sherds are performed by a skilled operator. Reviewed papers provided evidence that the traditional method is not reproducible, not repeatable, time-consuming and its results have great uncertainties. To overcome the aforementioned limits, in the last years, researchers have made efforts to develop computer-based methods for archaeological ceramic sherds analysis, aimed at their reconstruction. To contribute to this field of study, in this paper, a comprehensive analysis of the most important available publications until the end of 2019 is presented. This study, focused on pottery fragments only, is performed by collecting papers in English by the Scopus database using the following keywords: “computer methods in archaeology\", \"3D archaeology\", \"3D reconstruction\", \"automatic feature recognition and reconstruction\", \"restoration of pottery shape relics”. The list is completed by additional references found through the reading of selected papers. The 53 selected papers are divided into three periods of time. According to a detailed review of the performed studies, the key elements of each analyzed method are listed based on data acquisition tools, features extracted, classification processes, and matching techniques. Finally, to overcome the actual gaps some recommendations for future researches are proposed. Highlights: The traditional manual method for reassembling sherds is very time-consuming and costly; it also requires a great deal effort from skilled archaeologists in repetitive and routine activities. Computer-based methods for archaeological ceramic sherds reconstruction can help archaeologists in the above-mentioned repetitive and routine activities. In this paper, the state-of-the-art computer-based methods for archaeological ceramic sherds reconstruction are reviewed, and some recommendations for future researches are proposed.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42850757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
