Archeologia e Calcolatori 17 - 2006

The Archéologie du monde grec et systèmes d’information team (CNRS – Paris X – Nanterre) presents a survey of the web resources available for Archaeology in two parts, the first dedicated to developments and use of web products, the second to information retrieval. This article is focused on practices: access to research results transposed from a traditional edition to a web site; hybrid diffusion and original contents specially designed for the Internet; retrieval tools usually used, such as Google, distinguished between “portals” designed and developed by archaeological institutions: these portals allow researchers and students to find selected and qualified information. At the end of the text, we present our web sites: Mélanges électroniques en hommage à René Ginouvès, Bibliographie de l’architecture grecque, «Cahiers des thèmes transversaux», Chronique Internet pour l’archéologie.

The web site LIMC-France, created by the French team of the Lexicon Iconographicum Mythologiae Classicae (LIMC), is free and available in seven languages: English, French, German, Greek, Italian, Russian and Spanish. The site makes it possible to consult and search three different databases: – LIMCicon, the main database, gives access to file-cards gathering technical and scientific data relating to all Greek and Roman objects decorated with a mythological image that have been studied by the French team of LIMC, not only in French museums but also in several Near-Eastern, North African and East European countries. Most of the files are related to one or several digitized photographs. Each entry comprises a number of fields, all of them searchable, including bibliographical references, find-place, previous and current location, shape, iconographical description, key-words, etc. – LIMCbiblio updates the bibliography of LIMC articles from their publishing date onward. – LIMCabrev is a helpful tool giving complete titles of the abbreviations used in LIMC and in other publications of the LIMC Foundation.

This work focuses on the images representing the myth of Ajax, son of Telamon, as represented in a corpus of finds from Greece and pre-Roman Italy. The iconography of the classical myth is studied together with other characters, such as kind of object, production, painting technique, place of finding, age. The age was fixed in intervals of 50 years, because of the wide chronological range and the uncertainty of the age of some finds. The data table crossing the finds with the characters was first submitted to Multiple Correspondence Analysis, where a strong relation was revealed. This suggested that an attempt should be made to estimate the age on the basis of the other characters. Qualitative Discriminant Analysis, applied to the objects with certain age, gave good classification functions that were used to estimate the age of the finds with uncertain age. In conclusion, the examination of the graphs shows how different meanings and functions of a Greek myth are illustrated throughout Classical Antiquity.

This article describes two learning activities on Greek art and my reflections on the design elements which were influenced by the principles and recommendations that are particularly useful for distance education. The project arose out of a desire to emulate online the classroom experience of studying and analysing images of Greek art and had two goals: to provide students (1) with an opportunity to practise on their own visual analysis and interpretation of Greek images and apply them to new examples; and (2) with comprehensive but progressive feedback that would guide them in their way of thinking to reach the correct answer. In the Greek Art module, the activity assists students in dating vase paintings. Each example offers a choice of chronological periods in which to place the image. Errors in selection are used constructively, with the feedback providing hints on which elements of the image to pay attention to in order to arrive at the correct dating. Correct answers are accompanied by questions guiding students to consciously justify their selection. In the Greek Mythology module, the activity assists students in the identification of figures involved in mythological depictions. By clicking on the figures students can see not only the correct answer but also a series of questions that guide them to justify their answer by referring to the specific features on which they based their identification. These interactive activities can be used at the students own pace and provide immediate and constructive feedback. At the same time, they allow reflection before the correct answers, given in small successive steps, are revealed. The activities are linked to learning outcomes and prepare students for future summative assessment. They are a pedagogically sound computermediated tool to encourage active, deep and reflective learning.

The authors deal with the problem of a standardised but clear and easily understood framework for the strategic decisions involved in the selection among the diverse projects for the conservation and cultural and economic enhancement of archaeological sites. The aim of the paper is to explore the possibility of the use of fuzzy logic to create a hierarchy among the different projects. We propose the use of fuzzy numbers mathematics for the joint treatment of technical, landscape impact, economic and humanistic aspects in selecting the best conservation projects. The basic elements for the definition and the arithmetic of fuzzy numbers are given and a procedure based on the ordering is implemented. Finally, an application relating to an archaeological site on the Mediterranean Sea (Nora, Sardinia) is presented.

A methodology for the statistical estimation of the tumular dimension of simple megalithic monuments is developed through Simple Regression Analysis. Such a perspective may contribute to the global comprehension of badly preserved megalithic monuments and to establishing their role in the landscape; at the same time, and under certain circumstances, the statistical estimation can help in the planning of archaeological activities involving the monuments.

The increase in human population, economic development projects and the rapid expansion of inhabited areas in Iran are in conflict with the need to protect natural and cultural landscapes. Unfortunately, the natural and cultural heritage sites are the victims of these demands and they are increasingly being threatened by the growing population and their economic demands and land use before an archaeological study can be conducted. It is important to know that formulation of research policy and implementation of sound conservation-oriented management tools based on the proper research strategies could contribute toward arresting the problems while securing the existence of invaluable natural and cultural sites. A cultural landscape is, by definition, the sum of various kinds of landforms. The probabilities are that the cultural elements of a landscape may change dramatically through time as the surrounding landscape and land use patterns change. Since cultural landscape structure and change are fundamental determinants of land use, the approaches used in landscape management which emphasize environmental and cultural landscape homogeneity, offer some useful application in a holistic analysis of landscapes. This approach explicitly links archaeological studies of landscape with various land use patterns that may have affected cultural heritage structures. This paper attempts to make a contribution toward application of the above concept to cultural landscape. In addition the paper discusses the potential of an assessment method using statistics based on findings from a case study in Iran.

Artificial neural networks are adaptive models that can be used for classification and pattern recognition purposes. ANNs do not differ from standard statistical models. The main difference between ANNs and traditional statistical models is their construction and definition process. In fact ANNs are adaptive in the sense that they can learn. Landscape Archaeology is a research area where the application of ANNs can be very useful. ANNs can be used for Landscape pattern recognition and Settlement systems modeling. This paper illustrate some aspects of the development of new tools and the application of ANNs in a raster GIS environment for archaeological predictive modeling purposes.

How can an approach that at first seemed looking like a confused bazaar, from which just a miracle could let come out a stable and coherent system, work? If open source is demonstrating its success in the IT sector, can this approach be successfully applied also to the Cultural Heritage field? Integration, interdisciplinarity, participation, data sharing are key words of an open project, together with web use. In fact the use of the Internet will increasingly become not only a medium to communicate, often marginally, final results, but a real working tool. The paper will analyze a possible use of open source in archaeology, describing pro and contra of its use and comparing the characteristics of an open project with those of an archaeological one, underlying similarities and differences. A specific and new type of application will be described: VRwebGIS that will open new perspectives such as the interactive reconstruction of shared 3D web-based archaeological environments.

The systematic study of imports from the Orient uncovered in funerary contexts, as part of a research project the purpose of which is the reconstruction of the trade and cultural relations between the Aegean and the oriental basin of the Mediterranean in the Early Iron Age, has been supported by the relational database Ploes carried out in a MsAccess 2000 environment. Ploes represents an example of the possible meeting point between computer science and historical-archaeological research and testifies to the contribution that the computer science technologies can also offer to studies of the traditional school. The digital archives, that have replaced the conventional catalogue, have allowed the management of great amounts of data (1000 imported objects distributed in 300 tomb contexts) in a way that is functional for the purposes of research thanks to the possibility of creating a multiplicity of paths for reading the material. The Ploes database has allowed the storage of data related to individual objects and their discovery contexts in a single archive, thus making it possible to adopt a contextual approach to the analysis of the archaeological documentation. The structure of the digital archives reflects the defined methodological plan at the level of theoretical formulation of the study project: Ploes represents therefore not simply a container of information but an indispensable research instrument.

This paper aims to illustrate how the use of GIS tools and the application of spatial analysis techniques can help to enhance our understanding of the geographical, spatial and temporal dimensions of ancient landscapes. The theoretical and methodological point of reference of the research comes from the experience gained in a European context in the field of Settlement Archaeology, especially on a regional scale. Pre-Roman Daunia is a specific case study falling within a larger project that encompasses the whole of southern Italy, developed by the Laboratory of Archaeological Computing at the University of Lecce. Viewshed Analyses and Cost Surface Analyses were used to investigate the possible relationships between the physical and human landscape systems and to verify the presence or absence of a possible hierarchy among the sites belonging to these systems. Some interesting considerations emerged from the analysis of the Iron Age settlement system. In the earliest phases (10th-9th centuries BC), characterised by the absence of dominant towns, the settlements were organized into “small systems” made up of a number of sites, laid out in accordance with systems of physical landscape that seem to reflect precise choices; in the later phases (8th-first half of the 7th century BC), at the same time as the abandonment of the “small system” model of sites, the first signs of a hierarchy among sites emerge, and this begins to take more visible forms in the Archaic age. The work conducted on this case study has shown how the results of spatial analyses can provide the starting point for the formulation of new research hypotheses and surveying strategies in a territory where the surveys conducted up until now have tended to focus on the field of material culture, which is better documented thanks to the large collections of finds from funerary contexts, which have received more attention.

The project of incorporation and preliminary evaluation of a processing system for the description of pottery forms by means of the use of OMR and ICR devices is illustrated. This project, which has been implemented by the Laboratorio de Arqueoloxía of the Universidade de Vigo (Grupo de Investigación “Arqueoloxía Aplicada”), simplifies and speeds the recording of archaeological finds. The implementation of this type of system, applied in the analysis of finds coming from the Roman villa of Toralla, implies significant reduction in processing time of archaeological materials with the consequent advantages on the general process of investigation.

The Interactive Guide INandOUT, created as part of the project “Signs of pre-Roman cultures in land and landscape” and sponsored by the European Program “Culture 2000”, aims at experimenting new forms of comprehension by creating a direct link between site-visiting, excavations finds and archival research using the newest available technologies (notebooks, Tablet PCs, etc.). The Interactive Guide INandOUT answers the visitor’s need to contemplate the single work he is observing inside the site or museum and to observe it together with the entire site, at the same time. In short, it can place the visitor outside the site while still taking him through each single step of the excavations. Two goals have been achieved: first of all an informative net was created, covering vast open spaces (such as those found in archeological sites) and smaller indoor spaces (such as those found in museums), and using wireless technology (Wi-Fi, Bluetooth, GPRS, UMTS). Second, this net was filled with multi-medial contents, such as animations, movies, images, sounds and voices, in order to enhance the correspondence between inside and outside, between the single object and its original environment. The visitor’s position is identified by means of tags RFid (Radio Frequency Identification). These simple and quite “invisible” radio transmitters, spread all over the site, interact with the client-driver (the Tablet PC) given to the visitor. By receiving different specific codes the Guide recognizes where the visitor stands and sends him the most specific and contextual information. Last, but not least, the RFid system considerably reduces both operation and maintenance costs. The Tags used to activate the multi-medial information on the visitor’s Tablet PC are small, easily attached (even only using glue) and easily removed if necessary, long lasting, ideal for open and external spaces, and, most important, they need no power supply.

The excavation conducted since 2002 by the Department of Archaeology of Siena University in the s.c. Byzantine District near the Pythion shrine in Gortyn (Crete) gave the opportunity to develop some methodological reflections about the documentation of the cognitive process performed during archaeological excavations. From this point of view, GIS represents the end-point of an archaeological documentation system that links finds to their physical dimension and spatial position. But GIS appears to be at a hard point when it comes to recording the other side of archaeological information, linked with non-material evidence, functional and non-spatial relationships. This is the kind of information that emerges from the interaction between the clues and finds system and the reading/understanding ability of the team that does the fieldwork. This kind of interaction finds a better form of expression in a “narrative” language (multi-vocal excavation report and video recording). At the same time the opportunity of using a wiki as a platform for a web-based reconstruction of the team’s “mind map” was experimented. With this kind of system every piece of information can find its “place” for archiving, discussing and publishing.
