Assessing the level of visibility of cultural objects in past landscapes

Visibility is often understood to play a significant role in the placement of cultural objects within past landscapes. In recent years, GIS-based visibility studies have become popular as a method for assessing the role of views to and from sites and features. A significant drawback to these analyses is that they do not take into account how far an object can be clearly seen and recognized. A number of factors influence the visibility of objects, including the limits of human visual acuity, environmental effects such as atmospheric extinction, and the physical properties of object and surroundings. Current approaches that attempt to account for these influences focus on defining visual zones, but are limited because they do not directly address object size. A fuzzy viewshed approach, modified to account for target size, is suggested as a solution for assessing the level of visibility of cultural objects in past landscapes.     

The rise of cultural landscapes

The new interest in cultural landscapes is forcing a reappraisal of concepts of countryside heritage. First the traditional split between cultural and natural values is challenged. Second, modern landscape studies emphasise the subjectivity of landscape assessment, and this is subverting the former tendency to aspire to objectivity in evaluation. The acceptance of ‘associative’ value in landscape is an indicator of this. Modern landscape studies also emphasise the interrelationships between processes and aspects of value, and this is encouraging specialists to communicate across disciplinary frontiers. The desire by ecologists in the mid‐1980s to have cultural landscapes inscribed on the World Heritage list caused a re‐assessment of the World Heritage Criteria, and an initiative by ICOMOS brought this process to a conclusion in 1992. However the reappraisal of concepts of countryside value imply that there are many other philosophical and practical matters still to be resolved.     

Feasting landscapes and political economy at the Early Horizon center of Huambacho, Nepeña Valley, Peru

The present contribution examines feasting practices at Huambacho (800–200 cal. B.C.), an Early Horizon elite center of the Nepeña Valley, Department of Ancash, Peru. Feasts are approached as long-term strategies essential to the political economy of human societies. Drawing upon data from public architecture, material culture and food remains, the study closely considers feasts as political actions and investigates the organization and social meaning of these special events. At Huambacho, I contend that the diacritical aspects of feasting practices, such as the use of exclusive spaces and special paraphernalia, contributed to the dual celebration of communal identity and prosperity, and the creation and reproduction of social inequalities. The research highlights the dual centripetal and centrifugal dynamics of Early Horizon feasts and demonstrates the role of the Huambacho center in advertising the success of the local community based on new forms of production and innovative rules of commensal hospitality.     

Mapping ancient chinampa landscapes in the Basin of Mexico: a remote sensing and GIS approach

This paper uses remote sensing data to document a raised field, chinampa system adjacent to the Postclassic kingdom of Xaltocan in the northern Basin of Mexico. Various forms of landscape information; historic records and maps as well as remote sensing; are considered to understand the chinampa system. The remote sensing data examined include 1950s aerial photographs, Landsat 7 data, and Quickbird VHR, multi-spectral imagery. This article evaluates the utility of each of these forms of data to identify buried chinampa features and integrates them in a GIS to produce a map of Xaltocan's chinampa landscape. Canals of various sizes and hydrological positions comprised the chinampas and integrated the system together. Occupying at least 1500–2000 ha, Xaltocan's chinampa system represents the largest pre-Aztec, chinampa system in the Basin of Mexico.     

Airborne lidar survey of irrigated agricultural landscapes: an application of the slope contrast method

Irrigated agriculture was central to the economies of many of the world’s best known complex societies. New high-resolution digital elevation models (DEM) derived from remotely sensed lidar data give archaeologists the opportunity to study field systems at a scale not previously possible. Here we describe a method called slope contrast mapping that takes advantage of the dissimilarity between artificial and natural slopes to identify and map discrete features. We use this relatively simple method in our own research to identify complexes of agricultural terraces in the North Kohala district, Hawai’i Island. It has also proved useful for mapping the natural landscape, specifically the extent of flat land between valleys suited for irrigated agriculture.     

Storied landscapes makes us (Modern) Human: Landscape socialisation in the Palaeolithic and consequences for the archaeological record

The unusual nature of the Neanderthal archaeological record has attracted the attention of archaeologists for the past 150 years. On the one hand, the technical skill apparent in their lithic technology, the practice of symbolic cultural behaviours (such as burials), and their successful survival in harsh environmental conditions for more than 200,000 years demonstrate the adaptive success and underlying humanity of the Neanderthal populations. On the other hand, the apparent lack of abundant and repeated use of symbolic material culture has resulted in a number of researchers arguing that these populations were largely incapable of symbolism – a conclusion with significant implications for social organisation. This paper reviews ideas regarding the use of ‘place’ or ‘landscape’ by Neanderthals and argues that the identified differences between the archaeological records of Neanderthals and late Pleistocene Modern Humans is not so much the result of significant variance in cognitive capacities, but rather the use of contrasting approaches to interaction with the physical landscape. ‘Landscape socialisation’ is a Modern Human universal, but what if Neanderthals did not participate in this kind of landscape interaction? Would this difference in behaviour result in the apparently contradictory archaeological record which has been created? The ideas presented in this paper are drawn together as a hypothesis to be developed and tested.     

Multi-temporal archaeological analyses of alluvial landscapes using the photogrammetric restitution of historical flights: a case study of Medellin (Badajoz,Spain)

One of the main challenges affecting the archaeological study of alluvial landscapes is the intensity of change these environments experience over time. Quick and dramatic alterations in geomorphological dynamics and land exploitation determine the visibility and conservation of the archaeological record. This study proposes an approach to the problem of studying these evolving environments based on the analysis and treatment of a series aerial photographs taken between the 1950s and the present day. This paper is particularly interested in looking at the process of photogrammetric restitution and in validating and comparing the digital terrain models and orthoimages produced. The quantitative analysis and visual interpretation of these results can provide valuable information about the transformation of landscapes and factors affecting surface evidence. The intended final result is to develop the ability to map the most problematic or best preserved areas. Nevertheless, it is considered in terms of a relative measure of change magnitude, rather than trying to provide absolute figures.     

Using provenance data to assess archaeological landscapes: an example from Calabria, Italy

Ceramic provenance studies have helped archaeologists examine trade and exchange in multiple scales, the organization of production, and even vessel function. Yet, they may go even further, to provide a venue for the examination of past people’s perception of their landscape. To do so, a methodology is needed that links the choices prehistoric potters made, as reflected in their ceramics, with the choices their landscape could afford them, as reflected in the extent and distribution of local clays, and the physical, chemical and mineralogical characteristics of these clays. Using the region of Bova Marina in southwestern Calabria as a case study, we have combined a raw materials survey with field and laboratory experiments, along with chemical and mineralogical analyses of the collected sediments to understand the distribution and the physical, chemical and mineralogical variability of locally available clays and provide baseline data against which prehistoric ceramic materials from the region may be compared. We show that the local sediments can be divided into three major units, based on their macroscopic, mineralogical and chemical characteristics, that correspond well with the major geological units outcropping in the study area. While two of these units have internally consistent properties, the third is variable.     

Placing social interaction: An integrative approach to analyzing past built environments

A growing recognition of the vital role that built space plays in social reproduction has created a need for analytical methods and interpretive frameworks with which to investigate this relationship in archaeological datasets. I address this by developing an integrative approach that emphasizes the role of the built environment as the context for interactions through which social structures are created, transformed and reproduced. This approach uses access analysis to examine how buildings structure patterns of movement and encounter that allow social actors to engage in or avoid particular forms of interaction. With its focus on the topological properties of built space, however, access analysis does not take adequate account of a building’s symbolic aspects, especially architectural characteristics and furnishings that social actors mobilize in the creation of meaningful contexts for interaction. I therefore integrate access analysis with an examination of how built environments encode meanings and nonverbally communicate them to inhabitants and visitors, potentially influencing their actions and interactions. The integrative approach allows determination of probable contexts for various types of social interactions during which social identities could be displayed, negotiated and reified. I conclude by demonstrating the potential of this approach with an analysis of the monumental Ashlar Building from the Late Bronze Age (c. 1650–1100 BC) site of Enkomi, Cyprus.     

Sacred landscapes of the southern Brazilian highlands: Understanding southern proto-Jê mound and enclosure complexes

Fieldwork involving survey, detailed topographic mapping, and excavations in Pinhal da Serra, Rio Grande do Sul, Brazil, has revealed a highly-structured landscape revolving around funerary/ceremonial structures that began around A.D. 1000. This paper focuses on the results of detailed topographic survey of mound and enclosure complexes and their interpretation in light of southern Jê ethnohistorical and ethnographic data. We compare the architectural patterns of mortuary architecture from this study with fundamental spatial features of historic Kaingang’s social organisation, mortuary rituals and cosmogony myth. Our results suggest historical continuity in the organisation of space in cardinal directions (E–W), topography (low and high places), and in circular/concentric spatiality revealed in the southern proto-Jê mound and enclosure complexes. It is argued that small paired mound and enclosure complexes are associated with the material representation of a dual ranked opposition materialised in proto-Jê moiety cemeteries where important persona were buried.     

Provisioning Inka feasts at Tiwanaku, Bolivia: the geographic origins of camelids in the Pumapunku complex

While political integration can be achieved by many means, here we focus on the use of feasting and statecraft in the Inka Empire of the Andean Late Horizon (c. AD 1400-1532) in South America. In order to examine Inka political integration of the Lake Titicaca Basin of Bolivia, we examine paleomobility and paleodiet through radiogenic strontium and stable oxygen and carbon isotope data in archaeological camelid remains from the site of Tiwanaku. Mean radiogenic strontium isotope values from all archaeological camelid enamel and bone samples is ⁸⁷Sr/⁸⁶Sr = 0.70998 ± 0.00179 (1σ, n = 48), mean stable oxygen isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹⁸O_{carbonate (VPDB)} = −10.0‰ ± 2.6‰ (1σ, n = 18) and mean stable carbon isotope values from a sub-set of archaeological camelid enamel and bone samples is δ¹³C_{carbonate (VPDB)} = −9.0‰ ± 1.7‰ (1σ, n = 18). While many camelids consumed in these feasting events were likely local to the Lake Titicaca Basin, others came from a variety of different geologic zones, elucidating our understanding of Inka statecraft and the role of feasting in political integration in empires in the past.     

Ancient social landscapes of northwestern Argentina: preliminary results of an integrated approach to obsidian and ceramic provenance

This article presents the results of ongoing instrumental neutron activation analyses (INAA) conducted on archaeological artifacts from the Formative period of northwestern Argentina (NWA). These studies are part of a wider archaeological project that seeks to understand the structure of the social landscape of the period by examining domestic and burial evidence from a wide range of villages across the area known as the southern Calchaquí valleys. Elemental data is discussed in the light of its potential contribution to reassess past social interaction strategies in the region.     

Rock art as an archaeological and social indicator: The neolithisation of the Iberian Peninsula

Rock art has been regarded as a second class archaeological data source. In this paper we use Levantine rock art as a case study, to show how this situation can be reversed. This rock art, found along the Mediterranean region of the Iberian Peninsula, has been considered to be typically Mesolithic due to its distinctive hunting scenes. A review of certain archaeological indicators provides new arguments about its chronology, its socio-cultural attribution, and its significance. We first deal with the chronological issue, presenting the evidence that led to the recent consideration of the Levantine style as Early Neolithic, in synchrony with two other rock art styles (Schematic and Macroschematic). We will further propose that rock art itself is a central and independent source of information to explore the historical context of the Neolithisation of Mediterranean Iberia. Its wide geographical distribution allows us to study different and complementary territories as a single entity. This contrasts with the limitations posed by the study of settlements, whose differences, at a regional scale, are usually interpreted in terms of cultural variability. If we consider rock art as a key aspect in the constitution of social landscapes, it must not be treated just as an ideological by-product of the Neolithisation, but as a key factor in understanding this historical process.     

Modelling spatial heterogeneity and nonstationarity in artifact-rich landscapes

In this paper we consider a crucial issue for survey archaeology: how we identify and make sense of the heterogeneous and often inter-dependent behaviours and processes responsible for apparent archaeological patterns across the landscape. We apply two spatial statistical tools, kriging and geographically weighted regression, to develop a model that addresses the spatial heterogeneity and spatial nonstationarity present in the pottery distributions identified by our intensive survey of the Greek island of Antikythera. Our modelling results highlight a clear spatial structure underlying different scales of pottery density as well as locally varying relationships between pottery densities and several environmental variables. This allows us to develop further testable hypotheses about long-term settlement and land-use patterns on Antikythera, including more explicit models of community organisation, and of the relationship between the island's geomorphological structure and its history of past human activity.     

From abstract digital models to rich virtual environments: landscape contexts in Kilmartin Glen,Scotland

This study uses geographic information systems (GIS) based analyses and virtual reality (VR) reconstructions, to explore landscape context for two types of Neolithic monuments: cup and ring rock art and a stone circle. Specifically, the impacts of the contemporary vegetation at the study sites are analysed with regard to viewshed areas and views from the monument locations. Results show that while GIS-based viewshed analysis is useful for quantifying the absolute upper and lower limits for viewshed area, the virtual reality reconstructions allow the possibilities in between these extremes to be explored. In addition, VR provides the opportunity to explore visually rich representations of past environments for site interpretation and it is also a useful way for presenting uncertainty and testing different scenarios for landscape archaeology context.     

The contested interpretation of heritage landscapes in northern Ireland

Abstract

Because the nature of society is both negotiated and contested, cultural artefacts, including heritage landscapes, will be invested with differing and conflicting meanings by various social groups. This is but one aspect of what might be termed the dissonance of heritage. The present discussion is framed within the context of the argument that relics of the past are a resource to be selectively exploited in accordance with contemporary political and cultural demands. The paper uses the example of Ulster's Folk and Transport Museum to examine these issues. It concludes that while consumers do appreciate the cultural complexity of the Museum's role as one medium of communication of identity in a contested society, the institution's effectiveness in this regard is undermined by the middle‐class bias of those consumers.     

Quantifying tomb geometries in resistivity images using watershed algorithms

Quantifying the geometries (defined here as width, height and depth of burial) of archeological structures within resistivity models produced as a result of the regularization constraints used in most inversion algorithms is difficult, especially when structures are closely spaced. Here we apply the watershed by simulated immersion method of boundary detection to smooth 2D resistivity images generated for synthetic and field data over 3D targets. The synthetic studies include a single cavity model, a model for two widely spaced cavities (spacing ? unit electrode spacing) and a model for two closely spaced cavities (spacing < unit electrode spacing). We also examine a single-cavity model where a relatively resistive overburden, common at archaeological sites in Egypt, is included. In the case of the single cavity models, the maximum error for any geometries are 18% for the model without the resistive overburden and 10% for the model where the overburden is included, whereas it increases to 24% for the widely spaced model and 40% for the closely spaced model. Despite, the higher errors in the closely spaced cavity model, application of the algorithm confirms the presence of two features, which is not ascertainable from the smooth resistivity images. Boundaries detected with the watershed algorithm are subsequently used to define a disconnect in the regularization, resulting in a markedly improved estimate of the resistivity structure (particularly for the closely spaced cavity model) in a second inversion step using the model obtained from the smoothness constraint inversion as the starting model. This revised resistivity model also results in a lower root-mean-square (rms) misfit between measured and theoretical data, and between synthetic and inverted models. We demonstrate how the method can be applied on images from the archaeological site at Qurnet Murai, Luxor City Egypt.     

Animal landscapes: otters and wildfowl in England 1945–1970

The paper considers otter hunting and wildfowling in England between 1945 and 1970, showing how arguments over human conduct in relation to the animal were linked to scientific studies of populations, moral arguments over cruelty and the abilities of field sports to restyle themselves as modern. If wildfowling restyles itself as a new conservationist practice, otter hunting is increasingly regarded as a form of landed barbarism. Detailed studies of Herefordshire and Norfolk are drawn upon alongside national debates. The paper emphasizes the effects of geography in debates over such practices, extending work on animal geographies through the study of animal landscapes.     

Quantifying Ship Shape in Archaeology: Evaluating 3D Geometric Morphometrics

The analysis of the archaeological remains of ships and boats, in particular hull shapes, have been central to wider analysis of performance, function, and significance within past societies. This article reviews established methods of quantifying shape in ship and boat archaeology—linear measurement ratios and form coefficients—and evaluates the utility of 3D geometric morphometrics (GM). The 3D shape of 30 vessels from north‐west Europe dating between 325 BC and AD 1915 are quantified to study how hull shape relates to a vessel's function and intended operating environment. A comparison of the three methods highlights the importance of analysing the complexity of a hull in a holistic manner and demonstrates that 3D GM outperforms the traditional methods.
