Revisión de los métodos computerizados para la reconstrucción de fragmentos arqueológicos de cerámica

[ES] Las cerámicas son los hallazgos más numerosos encontrados en las excavaciones arqueológicas; a menudo se usan para obtener información sobre la historia, la economía y el arte de un sitio. Los arqueólogos rara vez encuentran jarrones completos; en general, están dañados y en fragmentos, a menudo mezclados con otros grupos de cerámica.El análisis y la reconstrucción de fragmentos se realiza por un operador experto mediante el uso del método manual tradicional. Los artículos revisados proporcionaron evidencias de que el método tradicional no es reproducible, no es repetible, consume mucho tiempo y sus resultados generan grandes incertidumbres. Con el objetivo de superar los límites anteriores, en los últimos años, los investigadores han realizado esfuerzos para desarrollar métodos informáticos que permitan el análisis de fragmentos arqueológicos de cerámica, todo ello destinado a su reconstrucción. Para contribuir a este campo de estudio, en este artículo, se presenta un análisis exhaustivo de las publicaciones disponibles más importantes hasta finales de 2019. Este estudio, centrado únicamente en fragmentos de cerámica, se realiza mediante la recopilación de artículos en inglés de la base de datos Scopus, utilizando las siguientes palabras clave: "métodos informáticos en arqueología", "arqueología 3D", "reconstrucción 3D", "reconocimiento y reconstrucción automática de características", "restauración de reliquias en forma de cerámica ". La lista se completa con referencias adicionales que se encuentran a través de la lectura de documentos seleccionados. Los 53 trabajos seleccionados se dividen en tres períodos de tiempo. Según una revisión detallada de los estudios realizados, los elementos clave de cada método analizado se enumeran en función de las herramientas de adquisición de datos, las características extraídas, los procesos de clasificación y las técnicas de correspondencia. Finalmente, para superar las brechas reales, se proponen algunas recomendaciones para futuras investigaciones.[EN] Potteries are the most numerous finds found in archaeological excavations; they are often used to get information about the history, economy, and art of a site. 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.Eslami, D.; Di Angelo, L.; Di Stefano, P.; Pane, C.

İspanya ve Yunanistan'daki antik tiyatroların bir sınıflaması jeo-tarihsel bir yaklaşım

This study offers an inquiry into the historical context of the invention, consolidation, and on-going popularity of the ancient theatre typology based on the Greek-Roman ءbinarism̕, for a better understanding of its philosophical and theoretical foundations. It scrutinises those foundations in order to discover, in their limitations for an assessment and restitution of the architectural characteristics of extant ancient theatre remains, a new set of variables for devising an alternative method of classification that adopts the ءnetwork̕ model. The classification made on the basis of the geographical distribution of the extant ancient theatre remains in modern Spain and Greece according to their size, their construction period, and the construction technique applied in their cavea enables an interpretation of Roman period theatre construction activity in these two regions of the Mediterranean from a ءgeo-historical̕ point of view, in the light of the variety of processes expressed by the term ءRomanisation̕. A comparative analysis of the examples in the two study areas along Fernand Braudel̕s three historical time planes reveals the structural differences between the two corresponding provinces of the Roman Empire, highlighting the usefulness of adopting a ءrhizomatic̕ model instead of a ءbinary̕ one in typological studies of ancient theatre architecture for their better integration into contemporary discourses emphasizing ءcultural diversity̕ and ءchange̕ in the Mediterranean basin.Ph.D. - Doctoral Progra

Treasures of Time. Research of the Faculty of Archaeology of Adam Mickiewicz University in Poznań

This publication presents the current scientific interests creatively developed by such teams at the Faculty of Archaeology of Adam Mickiewicz University. The research of these teams covers vast areas in time and space, summing up at least the last 9,000 years of prehistory. The following articles, arranged in chronological order, allow us to explore the prehistory of various areas

Optimo piscatu, Fish and fish-related finds from Roman Southern Pannonia and Upper Moesia as the evidence of global trade and local customs

Literary, documentary, and archaeological sources for fish preservation and fishing during the Roman period are quite big but the story about fish, fishing and imports of fish products in Pannonia and Moesia is untold. Fishing and fish processing are culturally defined, its context is complex and aspects of the economic significance are multilayered. A significant number of Roman fishing implements from Siscia, a representative amount of fish remains from Viminacium and evidence gathered from amphorae and pottery from both provinces present the basis for understanding its economic role. The social context of consumption of fish and fish products can be seen in the light of the global trade (e.g. Hispanic garum documented by amphorae) and the local customs (freshwater fish remains within the archaeological context). Analysis of fish and fish-related finds are excellent tool for understanding the long distance trade and local supply, as well as data on the nutrition of different classes within society of Roman provinces

Geological Heritage and Biodiversity in Natural and Cultural Landscapes

Geological Heritage has very diverse elements, both for its intrinsic nature and for its social and scientific significance. These elements have a scientific dimension (stratigraphic, geomorphological, lithological, paleontological, etc.) and a landscape dimension, both with implications for territorial management. In territorial management and planning, it is essential to carry out inventory and cataloging of places of natural and social interest to establish a comprehensive policy. The identification and valuation of the geological and biological heritage, and their interaction in the landscape should favor the conservation and preservation of this natural and historical heritage. Sustainable development implies rational use that prevents the degradation or loss of these unique environments of the natural environment as well as a dissemination and awareness of landscape resources for a better understanding and enjoyment, integrating activities of both environmental education and nature tourism.The diversity of a territory is the result of the complex and continuous interaction of the geological substrate (geotopical) and biological factors that model the existing ecological and evolutionary processes at the level of genes, species, ecosystems, and landscapes and that are expressed in a characteristic representation of organisms adapted to these factors. These vary according to the spatial dimensions and the temporal scales considered, in a wide range, that goes from the geological processes that involve millions of years and vast territories to the casuistic biotic, and anthropic events that can occur in an instant in any territorial sector

Finding the Limits of the Limes

This open access book demonstrates the application of simulation modelling and network analysis techniques in the field of Roman studies. It summarizes and discusses the results of a 5-year research project carried out by the editors that aimed to apply spatial dynamical modelling to reconstruct and understand the socio-economic development of the Dutch part of the Roman frontier (limes) zone, in particular the agrarian economy and the related development of settlement patterns and transport networks in the area. The project papers are accompanied by invited chapters presenting case studies and reflections from other parts of the Roman Empire focusing on the themes of subsistence economy, demography, transport and mobility, and socio-economic networks in the Roman period. The book shows the added value of state-of-the-art computer modelling techniques and bridges computational and conventional approaches. Topics that will be of particular interest to archaeologists are the question of (forced) surplus production, the demographic and economic effects of the Roman occupation on the local population, and the structuring of transport networks and settlement patterns. For modellers, issues of sensitivity analysis and validation of modelling results are specifically addressed. This book will appeal to students and researchers working in the computational humanities and social sciences, in particular, archaeology and ancient history

Archaeometric Investigation for Provenance Studies about Copper Metallurgy in the Phoenician and Punic Cultures

The doctoral thesis regards an innovative method based on an elaboration of chemical-physical data in terms of statistics and georeferencing of copper-based alloys artefacts in the Mediterranean and Atlantic regions which underwent the influence of Phoenician-Punic cultures. Fundamental aim of the research is the localization of areas where this influence is evidenced by the presence of artefacts which characteristics can be attributable to Phoenician and Punic presence. The chronological range considered is mostly between the Late Bronze Age (LBA) and the Early and Middle Iron Age (EIA- MIA), even if more ancient and more recent periods have been considered for coparison. The study of Phoenician-Punic archaeological sites, trade routes and the type of bronze processing have been considered broadly throughout the Mediterranean Basin and surrounding areas (but also atlantic and continental areas), leading to the production of databases containing information on archaeological settlements, mines and ore basins, and compositional data coming from literature or obtained from the analyses of bronze artefacts (SEM-EDS and EDXRF analyses), managed through an unprecedented application of Geographic Information System (GIS tool). So the GIS application includes data coming from archaeometric analytical sessions and from analogous researches published on specialised literature, carried out on samples of different typologies. The collected databases were elaborated on the basis of statistics-mathematic methods, in particular Principal Component Analysis (PCA), while frequency distributions and Box-Whisker diagrams have been used for the study of smaller datasets. The production of manufactures (small size metal statuary), connected to religious worship, were addressed in Alentejo, Portugal (Evora and Alcacer do Sal) and in Sardinia, Italy (Cagliari and Sassari). The mining and the production of slags and semi-finished products have been examined for Moroccan area (especially in Meknes Region) while metal artefacts of Roman period from Volubilis archaeological settlement have been analysed in the light of a probable technological conservatism between Punics and Romans. The production of bronze Punic coins was deepened for a private collection (Collection M. Viola) and through the study of Punic and neo-Punic finds in France, Belgium and in lesser extent in Northern continental Europe areas. The results have been interpreted with a unique perspective, so as to allow a new vision on the Phoenician presence an bronze production in the areas where they settled. Further result is the elaboration of a useful tool for the archaeological research that is reproducible in several fields, even different from the ancient metallurgy studies

Neolithic land-use in the Dutch wetlands: estimating the land-use implications of resource exploitation strategies in the Middle Swifterbant Culture (4600-3900 BCE)

The Dutch wetlands witness the gradual adoption of Neolithic novelties by foraging societies during the Swifterbant period. Recent analyses provide new insights into the subsistence palette of Middle Swifterbant societies. Small-scale livestock herding and cultivation are in evidence at this time, but their importance if unclear. Within the framework of PAGES Land-use at 6000BP project, we aim to translate the information on resource exploitation into information on land-use that can be incorporated into global climate modelling efforts, with attention for the importance of agriculture. A reconstruction of patterns of resource exploitation and their land-use dimensions is complicated by methodological issues in comparing the results of varied recent investigations. Analyses of organic residues in ceramics have attested to the cooking of aquatic foods, ruminant meat, porcine meat, as well as rare cases of dairy. In terms of vegetative matter, some ceramics exclusively yielded evidence of wild plants, while others preserve cereal remains. Elevated δ15N values of human were interpreted as demonstrating an important aquatic component of the diet well into the 4th millennium BC. Yet recent assays on livestock remains suggest grazing on salt marshes partly accounts for the human values. Finally, renewed archaeozoological investigations have shown the early presence of domestic animals to be more limited than previously thought. We discuss the relative importance of exploited resources to produce a best-fit interpretation of changing patterns of land-use during the Middle Swifterbant phase. Our review combines recent archaeological data with wider data on anthropogenic influence on the landscape. Combining the results of plant macroremains, information from pollen cores about vegetation development, the structure of faunal assemblages, and finds of arable fields and dairy residue, we suggest the most parsimonious interpretation is one of a limited land-use footprint of cultivation and livestock keeping in Dutch wetlands between 4600 and 3900 BCE.NWOVidi 276-60-004Human Origin

Ways and Capacity in Archaeological Data Management in Serbia

Over the past year and due to the COVID-19 pandemic, the entire world has witnessed inequalities across borders and societies. They also include access to archaeological resources, both physical and digital. Both archaeological data creators and users spent a lot of time working from their homes, away from artefact collections and research data. However, this was the perfect moment to understand the importance of making data freely and openly available, both nationally and internationally. This is why the authors of this paper chose to make a selection of data bases from various institutions responsible for preservation and protection of cultural heritage, in order to understand their policies regarding accessibility and usage of the data they keep. This will be done by simple visits to various web-sites or data bases. They intend to check on the volume and content, but also importance of the offered archaeological heritage. In addition, the authors will estimate whether the heritage has adequately been classified and described and also check whether data is available in foreign languages. It needs to be seen whether it is possible to access digital objects (documents and the accompanying metadata), whether access is opened for all users or it requires a certain hierarchy access, what is the policy of usage, reusage and distribution etc. It remains to be seen whether there are public API or whether it is possible to collect data through API. In case that there is a public API, one needs to check whether datasets are interoperable or messy, requiring data cleaning. After having visited a certain number of web-sites, the authors expect to collect enough data to make a satisfactory conclusion about accessibility and usage of Serbian archaeological data web bases
