Digital Support for Archaeology

Abstract

We describe an interdisciplinary approach in which computer scientists develop techniques to support archaeology. In the Reading Images for the Cultural Heritage (RICH) project, a variety of methods have been developed to support archaeologists in the visualization, categorization, and characterization of archaeological objects, such as medieval glass, coins, ceramics, and seeds. The methods are based on image processing and machine learning algorithms that are tailored to the task at hand. We describe the algorithms and illustrate their application on archaeological datasets. The virtues and pitfalls of the interdisciplinary approach to archaeology are discussed.     

Understanding residues of oil production: chemical analyses of floors in traditional mills

Oil production is an important aspect of ancient Mediterranean economy; therefore, archaeological studies on oil-producing installations using archaeometry and in particular the chemical analysis of absorbed residues is valuable in identifying the substances actually produced and to understand the spatial distribution of the activities carried out at oil mills.Modern contexts may provide a good reference for interpreting the archaeological chemical traces.This study examines the chemical traces in three abandoned oil mills in the Mediterranean: Polveraia (Tuscany, Italy), Martina Franca (Puglia, Italy) and Binibassi (Mallorca, Balearic Islands). To identify the residues released by the production of oil and absorbed by the floors, samples were taken from the floors of these installations and analysed using spot tests aimed at identifying the presence of fatty acids and phosphates. Some of the samples were analysed also with gas chromatography–mass spectrometry. The results of the analyses were plotted in the Geographic Information System (GIS) platform and interpolated with Inverse Distance Weighting (IDW) to determine the spatial distribution of the residues. Overall, the results show a large presence of fats in the analysed floors in all of the installations.     

Early Middle Ages Houses of Gien (France) from the Inside: Geoarchaeology and Archaeobotany of 9th–11th c. Floors

ABSTRACT

At Gien (France), indoor floors from early Middle Ages occupation (8th–10th c. AD) are very well preserved, providing a new reference for archaeological investigation in northern France. This site is located on an outcrop, 20 m above the Loire valley, where a 15th c. castle stands now. The medieval occupation combines high-status houses with crafting and agricultural areas. They constitute a new urban nucleus, which grew 2?km east from an ancient Roman settlement. During the rescue excavation, four buildings of different status were sampled and studied using an integrated approach, combining stratigraphy, micromorphology, chemical, macro-remain and phytolith analyses. Micromorphological investigations helped to identify 74 built floors, from 0.5 to 150?mm thick, made with transformed local clay or imported silty earth. Mineral floors were covered by vegetal ones, consisting of crop processing refuse. These litters include an abundance of phytoliths and some seeds, both produced by cultivated cereals, which were processed in situ, such as Triticum durum, Secale cereale and Hordeum vulgare. The refuse above the mineral and vegetal floors were trampled. They were produced not only by domestic activities, such as cooking and eating, but also by metallurgic activities and animal husbandry. The investigation of a contemporary pit indicated that, despite the large amount of refuse, floors were well maintained and regularly rebuilt. The spatial distribution of waste indicated that a single space could be dedicated to several activities, which were not necessarily separated by new floors. Moreover, the total absence of bioturbation allowed the study of a stage of dark earth formation, by comparing it to the contemporaneous mechanical disturbance of a part of the strata which occurred when building new floors. All these results give new evidence of the richness and the complexity of the early Middle Ages town, in addition to help identifying the activities which could take place in early castral areas.     

GIS,Archaeological Survey,and Landscape Archaeology on the Island of Kythera,Greece

Abstract

GIS and quantitative analysis are used to explore a series of simple but important issues in GIS-led survey. we draw on information collected during intensive archaeological field survey of the island of Kythera, Greece, and consider four questions: the relationship between terracing and enclosed field systems; the effect of vegetation on archaeological recovery; site definition and characterization in multi-period and artifact-rich landscapes; and site location modelling that considers some of the decisions behind the placing of particular Bronze Age settlements. we have chosen GIS and quantitative methods to extract patterns and structure in our multi-scalar dataset, demonstrating the value of GIS in helping to understand the archaeological record and past settlement dynamics. The case studies can be viewed as examples of how GIS may contribute to four stages in any empirically based landscape project insofar as they move from the spatial structure of the modern landscape, to the visibility and patterning of archaeological data, to the interpretation of settlement patterns.     

Geochemical analysis of Late Classic and Post Classic Maya marketplace activities at the Plazas of Cobá, Mexico

Abstract

Lines of evidence for ancient exchange plazas may include trade routes and trade artifacts, urban open space near public structures, and rock alignments denoting market stalls, but regular patterns in soil chemical concentrations also point to marketplace use. We applied geochemical and geospatial analysis of the floors of the main Plaza of Group B and Plazas A, H, and J of Group D at Cobá, Mexico, to discover the chemical residues of phosphorus (P) and metals associated with the exchange of foodstuffs and mineral workshop items that may have been marketed there. The patterns of chemical residues in the floor of the Group B Plaza suggest ritual activities while the linear, parallel patterns of elevated Mehlich phosphorus and chelate extractable zinc concentrations in Plaza A support the hypothesis of market exchange at that location. Plaza H is associated with several Postclassic buildings, including the Pinturas Structure D-33. During the Postclassic period, Cobá had lost much of its population, though chemical residues from Plaza H are congruent with marketing. We argue that Plazas A and H were not permanent marketplaces but rather multi-purpose locations that also hosted large ceremonies.     

Archaeology in Megalopolis: Updated Assessment

Abstract

Because of the “disturbed” nature of the terrain, archaeologists working in builtup “urban” situations frequently underestimate the possibilities for the survival of useful archaeological information. Recent experience, most of it in connection with federally-mandated historic resource surveys, has demonstrated that such disturbances are often quite superficial, and that important sites and features may exist, intact, beneath them. In fact, since all human activity disturbs the locale in which it occurs, the evidence of past construction and destruction may be the very resource that gives an area its historical and cultural importance. This paper presents examples of successful recovery of archaeological data in urban contexts in the northeastern United States, and discusses some as yet unsolved problems associated with this relatively new field of archaeological endeavor.     

Archaeology and Regional Identity in Saxony

Abstract

The paper discusses the interrelation between archaeological method and regional identity using the example of Saxony, a federal state of Germany. While the role of archaeology in the nationalist and ethnic discourse has been discussed relatively intensively, little is known about the hidden or open resistance present and the subnarratives used on a more local level. Saxony, with a multi-ethnic past (Germanic, Slavic and German settlement) and strong indications of a multi-ethnic identity, can be used to demonstrate the changing strength of the ‘Germanocentric’ view of German prehistory.

The paper follows the evolutions of the ‘Saxon character’ and its reflection in the archaeological narrative from the Romantic phase (c. 1817–70), through Nationalism, Fascism and archaeology in the GDR to modern times. This specific point of view does not only determine the evaluation of past events, but the questions asked and the methods used to interpret archaeological finds as well.

In conclusion, the ‘instrumentalization’ of archaeology as part of the public domain is seen as inescapable. But archaeologists retain responsibility for the use their data are put to. Any construction of identity by way of a common past is exclusive and potentially xenophobic. The author argues for a greater independencce from the past that leaves room for the recognition of distance and ‘strangeness‘.     

Palaeoecology and Archaeology of the Village of Uukuniemi,Eastern Finland

Abstract

In the present article, pollen analytical results from Lake Kirkkolampi are presented and compared with results provided by archaeological material. Pollen analysis is connected with the archaeological research project at Papinniemi in Uukuniemi. Papinniemi is one of the numerous Greek Orthodox settlements that existed in Karelia in the fourteenth to seventeenth centuries. Archaeological evidence of settlement preceding this period is very scarce, and in this respect Uukuniemi represents a typical area in eastern Finland. There is no archaeological evidence of permanent settlement in Uukuniemi from the Early Metal Period (c. 1800 bc–ad 400), the Middle Iron Age (c. ad 400–800) or from the Late Iron Age (c. ad 800–1300). Pollen analysis demonstrated the onset of cultivation c. cal ad 300. Marked intensification of agricultural activities and cultivation in permanent fields took place around cal ad 800. A shift in land-use practises, including a declining use of fire, is visible at cal ad 1520–1600. The discrepancy between archaeological and palaeoecological records raises several questions, and the problems of Early Metal Period and Iron Age populations, as well as settlement continuity, are discussed.

The following paper argues that archaeological analyses of communities of recent centuries can be as rewarding a means of understanding the past as the examination of the development of particular technologies.     

The Study of Archaeological Floors: Methodological Proposal for the Analysis of Anthropogenic Residues by Spot Tests,ICP-OES,and GC-MS

The identification of chemical activity residues on archaeological surfaces requires the analysis of large numbers of samples, which can be costly and time consuming. Researchers wishing to apply sediment chemistry often are confronted with a dilemma of which technique to use and how to accommodate sediment chemistry into their budget. We propose an approach to the identification of chemical activity residues in which semiquantitative spot tests, which are cheap, quick, and easy to apply, are employed as an initial phase of analysis in order to leverage the results of more time-consuming and costly instrumental techniques. Three examples that pair spot tests with gas chromatography-mass spectroscopy and inductively coupled plasma-optical emission spectrometry analysis show that spot tests successfully identify areas of interest. This approach can save both time and research funds.     

Identifying Threshing Floors in the Archaeological Record: A Test Case at Iron Age Tel Megiddo,Israel

Abstract

The identification of activity areas in archaeological sites is an important part of archaeological research contributing to the reconstruction of past ways of life. The threshing floor is an activity area that relates to subsistence practices in agricultural societies, yet identifying threshing floors in the archaeological record is difficult. We present a geoarchaeological study conducted at an Iron Age layered feature unearthed in 1998 at Tel Megiddo, Israel, in which we tested a previous assumption that it represents the remains of a threshing floor. Using micromorphology, mineralogy, elemental analysis, phytoliths, and dung spherulites, we show that the materials comprising the bulk of the layers in the Megiddo feature include large amounts of wood ash and the inorganic remains of livestock dung. Based on these results, coupled with ethnographic data on threshing floors and observations on the macroscopic traits of the feature under consideration, we conclude that the layered feature at Megiddo does not represent a threshing floor but a single-household trash heap. We suggest that the interpretation of similar features at other archaeological sites as threshing floors be reevaluated.     

Archaeology and conservation at Herculaneum: from the Maiuri campaign to the Herculaneum Conservation Project

Abstract

This article looks at two periods in the history of the archaeological site of Herculaneum (Italy) and the role of the archaeologist there. Amedeo Maiuri was in charge of the first major excavation campaign that uncovered the site from 1927 to 1961, but was also responsible for the site's restoration, presentation and maintenance. Much can be learnt from his approach, particularly with regard to site management – a fixed team of specialists continuously cared for the site – and his creation of what was effectively an open-air museum. The second example looks at the author's experiences with the Herculaneum Conservation Project, where the emphasis is on conservation interventions rather than excavation, but where the archaeologist has an important role in the conservation team and also has the opportunity to make new archaeological discoveries. The article concludes that the role of the archaeologist must evolve to include a professional responsibility for archaeological heritage that extends beyond its excavation.     

Site Conservation in Morocco: The Emergence of a Practice at Aghmat

Abstract

It is still uncommon for foreign and national archaeological excavations in Morocco to include architectural or site conservators during the excavation and post-excavation periods. The few existing examples of conservation have all been carried out long after the site or the building had been excavated. The site conservation activities during the Aghmat excavations in summer 2006 illustrate how the presence of archaeological conservators, advising the archaeological team and implementing urgent interventions, has ensured a safe excavation and has contributed to the preservation of the physical integrity of the excavated buildings. The excavation of the imposing archaeological features of the medieval bath of Aghmat provided the first opportunity in Moroccan archaeology for Moroccan archaeological conservators to be involved in condition assessment, planning, and provision of conservation activities to preserve the bath.

The primary aim of this paper is to present the site conservation experience in the Aghmat project, which is the first such project to be initiated during an excavation, and to be conducted mainly by a Moroccan team; it aims also to highlight the conservation procedures adopted and to incite discussion.     

Archaeological Ethnography,Heritage Management,and Community Archaeology: A Pragmatic Approach from Crete

This article examines the introduction of archaeological ethnography as an approach to establish positioned research and bring context-specific and reflexive considerations into community archaeology projects. It considers recent critiques of heritage management in archaeology and the role of archaeologists as experts in it, contending that smaller and less prominent sites exist in different contexts and pose different problems than large-scale projects usually addressed in the literature. We describe how the ‘Three Peak Sanctuaries of Central Crete’ project, investigating prehistoric Minoan ritual sites, involves communities and stakeholders and what demands the latter pose on experts in the field. Archaeological work is always already implicated in local development projects which create and reproduce power hierarchies. It is therefore important that archaeologists maintain their critical distance from official heritage discourses, as they are materialized in development programmes, while at the same time engaging with local expectations and power struggles; they also have to critically address and position their own assumptions. We use examples from our community archaeology project to propose that these goals can be reached through archaeological ethnographic fieldwork that should precede any archaeological project to inform its methodological decisions, engage stakeholders, and collaboratively shape heritage management strategies.     

环境考古中地层学研究的几个问题

地层学研究是从事环境考古研究的基础性工作。在从事环境考古地层学研究时,既不能硬套地质学方法,也不能照搬考古地层学方法,而是应当选择典型地层,采用地质地层学与考古地层学相结合的方法进行地层划分和地层对比。另外,还需引进相关学科的科学方法从事地层学研究。     

Combining residue analysis of floors and ceramics for the study of activity areas at the Garum Shop at Pompeii

In this paper, we propose the application—for the first time in the Mediterranean area—of the combination of the study of chemical residues in floors and ceramics, with the aim of providing information about the activities carried out in archeological buildings. We chose the Garum Shop at Pompeii to test the method. In fact, due to the peculiarity of this archeological context, it provided an ideal case in which the activities performed are in part known, and the ceramic vessels recovered are still in situ. Floor samples were studied by means of spot tests developed in Mexico aimed at identifying the presence of phosphates, fatty acids, and protein residues, while the organic residues preserved in the ceramic matrix of amphorae, dolia, and other ceramic vessels were studied by gas chromatography coupled with mass spectrometry. Moreover, we integrated the data obtained with specific studies directed at better identifying the solid residues found inside two of the amphorae studied: botanical studies of fruit stones recovered in a Dressel 20 amphora and the characterization of the lime preserved in an African amphora. The research allowed for the identification of the traces of some of the activities performed, such as cooking and producing garum in the floors of the building, and the use and re-use of amphorae and dolia before the Vesuvian eruption.     

Ancient agriculture and domestic activities: a contextual approach studying silica phytoliths and other microfossils in soils

Abstract

Based on microfossil and soil data, we discuss a different methodological approach to agricultural and domestic archaeological studies, taking two Formative sites in the north-west Argentinian high valleys (province of Catamarca) as case studies, independently of traditional datasets and historical analogies. As a result of our investigations we not only recognised the vegetal species cultivated in ancient fields (dated to c. AD 800) but also distinguished some of the agricultural practices, such as crop rotation and alternation, use of animal fertilisers and irrigation resources, as well as the abandonment of the site. From this perspective, corral episodes could also be distinguished. In residential enclosures, we obtained results concerning activity areas, the definition of floors and the identification of reoccupations.     

Archaeology on the Western Front: the Archaeology of Popular Myths

Abstract

The Sámi of today (the Lapps of yesteryear), currently divided from each other by the national boundaries of Finland, Norway, Russia and Sweden, have been, at least in part, ‘defined’ in the past by archaeology and its practices. In creating and modifying identities believedto be appropriate to the 21^st century, the Sámi facemany problems similar to other ‘indigenous’ and minority groups in the world. These include struggles to repatriate human remains and objects of material culture, others concern the use of the archaeological evidence to determine longevity of tradition and land rights, and still others demonstrate the role of heritage in the definitions of ethnicity and even in tourist presentations of what the Sámi might become, or might have been, or currently are.     

Assessing Methodologies in Archaeological Ethnography: A Case for Incorporating Ethnographic Training in Graduate Archaeology Curricula

Abstract

Archaeologists have increasingly turned to ethnography as a tool for understanding the contemporary social context of material culture, archaeological practice, and ‘de-colonizing’ archaeology. Furthermore, ethnographers have turned their analysis to the practice of archaeology, providing insights into key ethical dilemmas. This work has produced signi?cant dialogue, demonstrating the potential for research and collaboration at the interface of two sub-disciplines. However, much of the research to date has relied on a limited range of ethnographic methods. We suggest that archaeologists working in this area would bene?t from using a wider repertoire of ethnographic data collection tools and ethics training opportunities. We advocate for greater collaboration between archaeologists and ethnographers and provide suggestions on methods that are well-suited for use in archaeological practice. In the long term, the most effective and far-reaching solution may be to incorporate ethnographic methods training as fundamental to graduate programmes in archaeology.
