Immersive Visualization and Curation of Archaeological Heritage Data: Çatalhöyük and the Dig@IT App

Advanced data capture techniques, cost-effective data processing, and visualization technologies provide viable solutions for the documentation of archaeological heritage and material culture. Work at the UNESCO World Heritage site of Çatalhöyük has demonstrated that new digital approaches for capturing, processing, analyzing, and curating stratigraphic data in 3D are now feasible. Real-time visualization engines allow us to simulate the stratigraphy of a site, the three-dimensional surfaces of ancient buildings, as well as the ever-changing morphology of cultural landscapes. Nonetheless, more work needs to be done to address methodological questions such as follows: can three-dimensional models and stratigraphic relationships, based on 3D surfaces and volumes, be used to perform archaeological interpretation? How can a 3D virtual scenario become the interface to cultural data and metadata stored in external online databases? How can we foster a sense of presence and user embodiment in the simulation of ancient cities and archaeological sites? This article aims to provide viable solutions to the methodological challenge of designing a comprehensive digital archaeological workflow from the data acquisition and interpretation in the field to a three-dimensional digital data curation based on interactive visualization, searchable 3D data, and virtual environments. This work describes the results we achieved developing the application Dig@IT, a multi-platform, scalable virtual reality tool able to foster archaeological data analysis, interpretation, and curation in a realistic and highly interactive virtual environment.     

Planning reform and development rights in Greece: institutional persistence and elite rule in the face of the crisis

This paper discusses the process of development rights allocation in Greece and the changes to that process which occurred from 2009 onward. It argues that the interaction of institutions which regulate the allocation of development rights, with social practices of formal and informal land development, gives rise to development pathways which demonstrate institutional persistence. In the case of Greece, these pathways range from ‘urban development by state organisations’, to development without planning permission on land that is not owned by the developer. The crisis was a shock to the Greek governance system, yet the analysis in this paper shows that the reforms of the development rights allocation process followed the pre-existing ‘mentality of rule’. The paper therefore argues that development pathways reflect a political arrangement between the ruling elites and other social strata. The technologies of governance and the associated institutions and practices which support elite rule, were sustained, if not reinforced, during the crisis. This analytical approach therefore offers insights of relevance to other countries in Europe and around the world which contemplate reforms to their development rights allocation system.     

Evaluating the Potential of Semi-Automated Image Analysis for Delimiting Soil and Sediment Layers

ABSTRACT

Established methods for delineating anthropogenic and natural strata during fieldwork are based on the visual and tactile perception of excavators. Modern image analysis techniques can help to ensure objectivity and reproducibility when documenting sections and plana. Within this study we examine the unsupervised classification of digital images as a technique for delimiting layers and identifying stratigraphic features. Assessing the potential of this approach, we exemplarily captured soil profiles with high-contrast stratigraphy, located in the area of a historical vineyard (Brandenburg, Germany). Reproducible analyses were carried out using open-source software, allowing for the future advancement of the methodology utilized and providing a basis for the analysis of more complex stratigraphic sequences. We compare clustering results of high-resolution RGB and hyperspectral images (470–830?nm, 37 bands). Multiple pre-processing and processing steps are carried out to evaluate their influence. Our results render the semi-automatic analysis of RGB images helpful for stratigraphic interpretation.     

中西传记史学的产生及其趋向之比较

中西传记的史学观念与中西所共有的原始宗教文化形式紧密相关,并在叙事史学的基础上得以产生。在古希腊罗马,由于自然崇拜、英雄崇拜和祖先崇拜在其文化结构中的矛盾运动,传记史学兴起后自成一体,与叙事史学并行不障;而中国则由于祖先崇拜长期占据优势,传记史学在叙事史学的基础上产生后,遂将叙事史学同传记史学结合起来,定为一尊,形成正统的史学体裁。比较研究中西传记史学的产生及其趋向具有重要的现实意义。     

Pre‐Industrial Iron Smelting and Silver Extraction in North‐Eastern Greece: an Archaeometallurgical Approach

In contrast to Western Europe's well‐documented contribution to global industrialization, Eastern Europe has not received adequate attention. This paper addresses this asymmetry by defining a secure socio‐technical framework for the development of metallurgical technology in one of the most important mineralized zones in Eastern Europe, namely the uplands of north‐eastern Greece. The interplay of technological innovation, geography and social process has made this region central in European political history from the Classical and Roman periods up to recent times. Metal procurement has been crucial particularly between the 15th and 19th centuries ad, when armed conflicts escalated across the Balkans and the high inflation throughout Europe increased the demand for raw materials from the East. Field data from north‐eastern Greece and instrumental analysis corroborate the concept of iron extraction during this period from complex ores that were potentially used for their precious metals contents as well. Chemical analysis of slag points to iron bloomery processes, while analysis of respective residues (speiss) reveals significant concentrations of silver and thus testifies to the extraction of precious metals. This study addresses concerns that preoccupy political and technological minds today, and provides a context for understanding the effects of changing attitudes to the environment, social development, consumption and natural resources.     

On-Site Recording of Excavation Data Using Mobile GIS

Abstract

Archaeologists have embraced new technologies in many aspects of research, but reliance on paperbased recording has impeded development of excavation recording methods. The digital recording of spatial provenience for artifacts and features, together with complex attributes during excavation, while not problem-free, provides a streamlined recording process. This article describes a digital interface that links precise spatial provenience with digital forms and geo-referenced photographs during excavation at a colonial site in highland Peru. A customized version of ESRI ArcPad provides the means to create and to explore spatial and attribute data in the field and laboratory as GIS data, which in turn can be integrated with ArcGIS for post-field visualization and analysis.     

The hypocrisy of European moralism: Greece and the politics of cultural aggression – part 1

In the current debt crisis, Greeks often stand accused of irresponsible borrowing, corruption, and laziness. In this article, I argue that the patently unfair way in which these stereotypes have framed the ongoing tensions between Greece and the other European countries is deeply grounded in the dynamics of “crypto‐colonialism.” German fascination with ancient Greece has combined with the needs of British, French, and, later, American strategic interests to produce a toxic brew of humiliation and contempt for the Greek people of today. Yet Greece, by escaping from the aftermath of military dictatorship under the unexpectedly benign guidance of the elder Constantine Karamanlis, is now – in marked contrast to at least one other crypto‐colonial state – giving the unelected leadership of the European Union and other creditors a lesson in democratic self‐sufficiency. Resolution of the residual tensions will nevertheless only be possible when both sides agree to cease trading insulting stereotypes and admit the errors of a shared and embarrassing past – a process for which anthropological perspectives can offer significant support.

Towards a Living Archive: Making Multi Layered Research Data and Knowledge Generation Transparent

ABSTRACT

Çatalhöyük was first discovered as one of the earliest urban settlements in the late 1950s and excavated by James Mellaart between 1961 and 1965. The 9000-year-old town in central Turkey rapidly became famous internationally due to the large size and dense occupation of the settlement, as well as the spectacular wall paintings and other art that were uncovered inside the houses. Since 1993, under the direction of Ian Hodder, research at Çatalhöyük has pioneered a reflexive approach to archaeological practice, in which information is permanently open to reinterpretation by both scholars and the public. This approach acknowledges the mutual dependence of knowledge and the underlying research, to which end the Çatalhöyük Project decided to make its records available via the Web and to invite public comment since its onset. After 25 years of excavation, the project’s digital assets now amount to close to 5TB, including formal textual and numeric records, freetext documents, audiovisual materials, and a comprehensive collection of spatial data. The reflexive method, or ‘documentation of the documentation process,’ adds a separate layer of information that specifies how data have been gathered, and facilitates critique, understanding, and the evolution of knowledge.

In this paper we lay out our vision of an interactive archive that provides access to the multi layered information contained in this massive amount of data and how web technological advances have been incorporated into the digital data management at Çatalhöyük. Ultimately, the goal is to support an interdisciplinary process of assembling data into arguments on the basis of multiple lines of evidence. The ‘Living Archive’ will enable intuitive engagement across the entire variety of research, making use of the rich reflexive information stored with the data. The results of new analyses can in turn be reintegrated with the already existing data. The application will use open standards so that the knowledge gathered at Çatalhöyük can be linked with other projects that follow similar publication procedures based on the semantic web approach.     

The face of the poet Dante Alighieri reconstructed by virtual modelling and forensic anthropology techniques

This paper describes the multi-disciplinary approach to reconstruct the face of Dante Alighieri (1265–1321). Since Dante's sepulchre will be opened in 2021, the reconstructive process is based on morphological and metric data collected on the poet's cranium during the formal identification of his remains in 1921 by the anthropologist Fabio Frassetto, as well as on the resulting plaster model. Starting from this plaster model and a morphologically compatible reference mandible, since the original mandible was never found, a 3D digital model of the complete skull was obtained by reverse engineering and virtual modelling techniques. The most important aspect in this work was the method of virtual modelling proposed for the ex novo generation of the mandible. The physical model of the skull (cranium + mandible) was then produced by means of a rapid prototyping system. This model was finally used to recreate Dante's face via traditional facial reconstruction techniques currently used in forensic anthropology.     

NISP, Bone Fragmentation, and the Measurement of Taxonomic Abundance

Zooarchaeologists have long recognized that the number of identified specimens (NISP) is dependent on the degree to which bones are fragmented, but attempts are rarely made to control for the effects of fragmentation on NISP. This paper provides insight into those effects by presenting both a formal model of the relationship between NISP and fragmentation and experimental data on that relationship. The experimental data have practical implications regarding the effectiveness of potential measures of bone fragmentation, suggesting that specimen size—which can be determined easily through digital image analysis—is more useful than other variables that have been or might be used as fragmentation measures.     

Buried assumptions: Some problems in the interpretation of the “Younger Fill” raised by recent data from Greece

A distinctive “Younger Fill” has been identified in the Mediterranean and adjacent regions. The dominant explanation for it is that of climatic change, first advanced by Vita-Finzi in 1960. Recent work on Greece by Bintliff appears to support the hypothesis. However, there are weaknesses. The present paper isolates the assumptions upon which the climatic hypothesis rests, particularly the notion of synchroneity and the apparent need for a universal mechanism. It sets out the grounds for scepticism, which include the ambiguity of the data, and attempts to evaluate the recent evidence from Greece. The paper then proceeds to argue that an anthropogenic origin cannot be ruled out and that it merits serious consideration. Criteria are suggested which the reinstated explanation would need to meet.     

Strategic Participatory Planning in Archaeological Management in Greece: The Philippi Management Plan for Nomination to UNESCO’s World Heritage List

Abstract

This paper examines appropriate conditions for effective strategic participatory planning in archaeological heritage management. It is suggested that heritage literature often considers the tangible outcome of strategic participatory planning, the management plan, as an end of the planning process in itself. Drawing from experience in drafting a management plan for the archaeological site of Philippi in Greece, conventional archaeological management in the country is discussed followed by the identi?cation of constraints on and bene?ts from strategic participatory planning. This paper argues that more critical approaches to the actual planning process are necessary for strategic participatory planning to continuously improve as an approach in Greece and elsewhere.     

XRF analysis of glass beads from the Mycenaean palace of Nestor at Pylos,Peloponnesus, Greece: new insight into the LBA glass trade

In recent years there has been a growing interest in Mycenaean glass among archaeologists and scientists. Scholars have traditionally thought that all Mycenaean glass was imported either in finished form or as ingots and simply shaped or worked at the Mycenaean sites. Chemical studies of other Mycenaean glass (50 and 43) support the hypothesis that glass was imported into Mycenaean Greece, but there is also indication for glass production in mainland Greece at the palace of Thebes (Nikita and Henderson, 2006). There is no evidence for glass making or working at the Palace of Pylos, yet there is an abundance of glass beads there. The aim of this paper is to identify the technology and source for the glass of these beads and thus to ascertain how Pylos was connected to the broader Mycenaean and Mediterranean economies. The composition of the glasses was determined by means of portable XRF analysis and compared to that of other Late Bronze Age glasses from Egypt, Mesopotamia and mainland Greece. Four blue beads coloured with cobalt and one blue bead coloured with copper have Ti and Zr compositions consistent with an Egyptian origin of manufacture while five other beads show Ti and Zr concentrations consistent with a Mesopotamian origin (Shortland et al., 2007). Based on the dearth of Egyptian and Mesopotamian imports in Pylos, the presented data support the hypothesis that Pylos was receiving via internal Greek trade routes foreign-produced glass, which may have been worked abroad or in Greece.     

New Middle Palaeolithic sites from the Mani Peninsula,Southern Greece

We here report the first results from a systematic research project in Mani (Southern Greece), which includes survey and test excavations. Forty-six caves, rockshelters and open-air sites in lowland settings were surveyed. Geomorphological data were collected in order to assess how geological processes affect the preservation of sites and bias site distribution patterns. Artifacts manufactured from non-local rock indicate potential raw material transfers and suggest links among the different regions of Mani, related to mobility patterns. Our research in the Mani has nearly doubled the number of known Middle Palaeolithic sites from the region and confirmed that the peninsula has the strongest ‘Neanderthal signal’ identified to date in Greece. Almost all sites are located at coastal areas. Despite the influence of Pleistocene landscape dynamics, this distribution emerges as a persistent pattern, perhaps indicating a preference for coastal locations. The Neanderthal occupation of Mani can illuminate important aspects of Middle Palaeolithic adaptation in one of the southernmost coastal regions of Europe.     

A Complete Chemical Grouping of the Berkeley Neutron Activation Analysis Data on Mycenaean Pottery

The Perlman–Asaro data bank contains nearly 900 data sets of Mycenaean and Minoan sherds which were sampled in different regions of Greece and Crete. The data were obtained from Neutron Activation Analysis measurements at Berkeley in the 1970s, and for each concentration value a corresponding uncertainty of measurement was also recorded. Parts of the contents of the data bank have been published before. Here, we present the first complete statistical analysis of the whole data bank, considering measurement errors as well as constant shifts of the data due to pottery making practices (“dilutions”). We establish new reference patterns for different regions of Greece and Crete and compare the results with the contents of our own group data bank in Bonn. For those parts of the data which have been published previously, a comparison between these studies and our recent investigation is presented.     

Regional Survey and the Boom-and-bust Countryside: Re-reading the Archaeological Evidence for Episodic Abandonment in the Late Roman Corinthia

This paper reexamines the archaeological evidence for three episodes of rural abandonment and resettlement in the countrysides of Late Roman Greece (200–700 CE): an abandoned Late Hellenistic-Early Roman countryside (second century BCE to third century CE), a decline in the third to early fourth centuries CE, and the Dark Age beginning in the seventh century CE. The first and third episodes of abandonment, especially, have sharply defined Late Antiquity (250–700 CE) as a healthy period of new rural settlement and economic resurgence, and the entire pattern has been described in the terms of “boom-and-bust” demographic and economic cycles. Closer readings of the archaeological data can contribute to more sensitive pictures of continuity and change in settlement and connectivity in the late antique Corinthian countryside and other regions in Greece.     

Intrasite features distribution as a source of social information: The case of Djaba-Hosséré (Northern Cameroon)

The spatial organization of Dìì settlements has been considered as the reflection of the peculiar social organization of Dìì chiefdoms: a model based on an association of several lineages, most of them being necessary for the working of the whole. The distribution of thousands of surface remains (features and ceramics) located on the eastern foot of the Djaba massif, the site of the eponymous chieftaincy in the early 19th century, together with stratigraphic data, is likely to provide information about the age and the foundation process of a Dìì chiefdom. Following the spatial analysis, we will see that, locally, the growth of political complexity began about the 18th century and that this process may have resulted in the arrival of ‘foreigners’ among one or more of the autochthonous communities, one of what appears to have been strongly involved in metallurgical activities. Archaeological data seems thus to indicate that the foundation myth of the ‘generous foreigner’ shared by most of the Dìì chieftaincies was based on historical events.     

A theatre of machines: Automata circuses and digital bread in the smart city of Toronto

In this paper, the policies, projects, and promises of “smart” initiatives at the City of Toronto are evaluated, as they manifest through a technological convergence between local government services and an increased focus on citizen services through data-driven mediums. Through direct participant observation and formal interviews, a robust understanding of the internal institutional dynamics, the perspectives citizens in the “smart city,” and the operational disconnects in governance, policy, and practice has been gained. Our case study on the City of Toronto provides an account of how and from where these smart motivations for increasing a data-driven engagement with the public have arisen over the past several years. In doing so, we identify key characteristics that both enable and hinder the existing smart city in the forms of access to open data, the use of increased computational methods, and the engagement of public services through digital space as requirements for the future of participatory governance. We argue that instituting appropriate policies and engaging citizens to co-design and participate in the planning processes are essential to ensuring an inclusive, modern, and open smart city.
