The potential of paleoethnobotanical evidence for the study of Teotihuacan foodways

Macro- and microscopic plant remains recovered from excavations at Teotihuacan over several decades contribute to an understanding of the subsistence resources available to the city’s inhabitants. However, associated contextual evidence may be inconclusive regarding the specific uses of the plants in question and, particularly, whether their presence or relative abundance indicates processing and consumption or the consequence of depositional processes. While the analysis of archeological plant remains is necessarily an interdisciplinary endeavor, involving aspects of botany, ecology, ethnography and history among other disciplines, contextual archeological evidence provides the matrix for interpretation. In this paper, we explore direct archeological evidence for plant use, considering the significance of appropriate contextual evidence (e.g., activity areas, associated ceramics, lithics, etc.) and the potential complementary role of analytical techniques such as residue analyses, and carbon isotope signatures in faunal and human osteological remains as well as stratigraphic sediments.     

Expanding the research parameters of geoarchaeology: case studies from Aksum in Ethiopia and Haryana in India

A wide-ranging geoarchaeological approach is put forward using two case studies in northern highland Ethiopia at Aksum and in Haryana province of northwestern India where the authors are part of collaborative archaeological research projects. Geoarchaeological approaches are well placed to underpin archaeological project design and contribute to the understanding and modelling of the human ecosystem legacy. There is also the potential to use that data to both inform wider audiences of the importance of long-term land-use dynamics in shaping our landscapes today and influencing modern land-use policy and implementation.     

Staple food preparation at Teotihuacan

Like studies of craft production, research on food production has significant implications for understanding the economic organization of past societies. This paper highlights the tools of maize (Zea mays) processing and cooking as a constructive avenue to examine aspects of food production at Teotihuacan during the Terminal Formative and Classic Periods (100 BC–AD 650). By analyzing the spatial distribution of comales, metates and manos recovered from the Teotihuacan Mapping Project, this study investigates the notion that edible maize products were produced through specialized labor. Two notable patterns are observed. First, the aggregation of comales along the Street of the Dead during the Miccaotli phase (AD 100–170) suggests that tortilla preparation fueled large public work projects, feeding the workers, their families, and other dependents of the state. Secondly, the spatial aggregation of grinding stones, manos and comales in seven concentrated areas within the Classic Period (AD 170–650) occupation of the city suggest that several apartment compounds, possibly entire barrios, may have specialized in the production of tortillas and other finished maize foods for exchange. Such a pattern may have resulted from the costly labor and materials required for the production of tortillas, favoring economies of scale. Several areas within the city conspicuously possessing low frequencies of maize processing artifacts suggest that some sectors were dependent on specialized labor from outside the household for daily needs. Together, these data suggest that food production was a specialized activity at Teotihuacan and increase our understanding of the economic organization of the ancient metropolis.     

Discussion: the subsistence of the Teotihuacan metropolis

In this chapter, the issue of how the huge multiethnic metropolis of Teotihuacan was fed will be addressed reassessing data from four different contexts:

1. 1.
   The apartment compounds where people dwelled
    
2. 2.
   The neighborhood centers where many people of different origins worked
    
3. 3.
   The palatial structures of the ruling elite
    
4. 4.
   The rituals inside the main pyramids
    

My extensive excavation project at the multifamily apartment compound of Oztoyahualco 15B:N6W3 (1985–1988) provides the primary dataset to address the first context; there, the faunal and floral remains relate directly to food preparation and consumption, as well as fuel provisioning, manufacture, and domestic ritual. My project at the multiethnic neighborhood center of Teopancazco (1997–2005) addresses the complexity of multiethnic relations established through caravans linking Teotihuacan with allied sites along the corridor towards the Nautla region of the Gulf Coast of Veracruz. Foreign fauna, as well as cotton and other raw materials and products, arrived to Teotihuacan through these caravans, together with migrant specialized craftsmen/women. The third context will be addressed through my excavations in Xalla, a huge palatial complex to the north of the Pyramid of the Sun, where the ruling elite participated in ceremonial and sacrificial activities. The fourth context will only be mentioned briefly and is related to the excavations in the main monumental structures, where faunal and floral remains were associated with consecration rituals, as well as those found in the fill of these structures.     

Seen but Not Told: Re-mapping Great Zimbabwe Using Archival Data,Satellite Imagery and Geographical Information Systems

The world renowned site of Great Zimbabwe is one of the most globally significant archaeological sites in Africa. Ironically, this importance is not matched by the little amount of information that is known about such an iconic site. The heritage of this regrettable situation was birthed by the destructive activities of late nineteenth and early twentieth century antiquarians who vandalised tons of evidence without record. Throughout the twentieth century, however, professional archaeologists made interventions that rescued information from various parts of the site but most of which was never published. A moratorium imposed on archaeological excavations at the site in the early 1990s failed to stimulate an active engagement with material that was archived since the first professional excavations began. Motivated by the need to understand the site in new ways, research was initiated to revisit the site’s patchy and scattered archives and to supplement them with field surveys. This paper discusses the re-mapping of the site which, for the first time, comprehensively produced themed layers of spatial, chronological and material culture distribution. The main outcome is that most existing maps ignored a large number of terraces on the hill and omitted evidence of occupation in key areas. When combined with excavation profiles that expose the massive rebuilding of the site by original residents, it becomes clear that settlement ebbed and flowed during the more than six centuries of occupation at the site.     

Influence of Handaxe Size and Shape on Cutting Efficiency: A Large-Scale Experiment and Morphometric Analysis

Handaxes represent one of the most temporally enduring and geographically widespread of Palaeolithic artifacts and thus comprised a key technological strategy of many hominin populations. Archaeologically observable variation in the size (i.e., mass) and shape properties of handaxes has been frequently noted. It is logical to ask whether some of this variability may have had functional implications. Here, we report the results of a large-scale (n?=?500 handaxes) experiment designed to examine the influence of variation in handaxe size and shape on cutting efficiency rates during a laboratory task. We used a comprehensive dataset of morphometric (size-adjusted) shape variables and statistical methods (including multivariate methods) to address this issue. Our first set of analyses focused on handaxe mass/size variability. This analysis demonstrated that, at a broad-scale level of variation, handaxe mass may have been free to vary independently of functional (cutting) efficiency. Our analysis also, however, identified that there will be a task-specific threshold in terms of functional effectiveness at the lower end of handaxe mass variation. This implies that hominins may have targeted design forms to meet minimal (task-specific) thresholds and may also have managed handaxe reduction and discard in respect to such factors. Our second set of analyses focused on handaxe shape variability. This analysis also indicated that considerable variation in handaxe shape may occur independently of any strong effect on cutting efficiency. We discuss how these results have several implications for considerations of handaxe variation in the archaeological record. At a general level, our results demonstrate that variability within and between handaxe assemblages in terms of their size and shape properties will not necessarily have had immediate or strong impact on their effectiveness when used for cutting, and that such variability may have been related to factors other than functional issues.     

Envisioning Artifacts: a Classic Maya View of the Archaeological Record

This paper explores a Classic Maya (ca. AD 250–900) “material vision”—that is, a locally determined and culturally specific way of understanding the material world, its salient qualities, and associated meanings—based on evidence found in hieroglyphic texts from across the Maya world. Understanding Classic Maya ways of seeing the material world is an important undertaking as part of exploring alignments and misalignments between ancient indigenous and modern archaeological understandings of what today we view as “artifacts.” This topic is explored in the article through two related inquiries: first, I look at “artifacts” (i.e., materials that qualify as such, in an archaeological material vision) recorded in the hieroglyphic record, yielding thematic understandings of objects related to form and function, wholeness versus brokenness, and the relational potential of objects. Second, I use ten hieroglyphic property qualifiers that indicate Maya material perceptions and categories to gain explicit insight into some organizing principles within a Maya way of visualizing the material world. Throughout the article, I ask: can we envision archaeological objects using Maya conceptions, and how does this way of seeing align or misalign with archaeological material engagements?     

Exploring Accumulation Rates of Shell Deposits Through Seasonality Data

Shell middens are often analysed as the result of short- or long-term depositional activities. In order to confidently interpret such deposits, it is necessary to have accurate estimations of shell accumulation rates, most commonly produced by radiocarbon dates. This paper introduces the application of seasonality data as a temporal measurement of short-term shell deposition. This gives access to an additional estimate of shell accumulation rates, which work on a shorter timescale than can be analysed through radiocarbon dating. We focus on shell deposits on the Farasan Islands, Saudi Arabia, which comprise over 3000 shell midden sites dating to the mid-Holocene (6500–4500 calBP). One site (JW1727) was chosen to (1) explore the potential of seasonality data to reconstruct accumulation rates, (2) analyse the intensity of exploitation and (3) assess the visibility of short-term shellfish deposits. Stable oxygen isotope values (δ¹⁸O) were obtained from the marine gastropod Conomurex fasciatus (Born 1778), representing 72 % of the shell weight of JW1727, to reconstruct season of capture. Seasonality data was grouped by their spatial distribution, which allowed successive episodes of deposition within a stratigraphic sequence to be connected. This allowed us to make an estimation of exploited shell meat of ～200 kg over a 7-month period (～400 shells/day). We argue that excavation methods and low resolution stratigraphic data cause imprecision in the seasonality data and the low visibility of rapidly accumulated shell deposits. Also, an increase of analysed shells per layer is key to understanding the seasonal brickwork of more middens in the future.     

Mesh Is More—Using All Geometric Dimensions for the Archaeological Analysis and Interpretative Mapping of 3D Surfaces

In various disciplines, particularly those that utilise techniques developed in the geosciences, the display, analysis and interpretation of three-dimensional (3D) data is very important. This is also the case in archaeology. Irrespective of a site- or landscape-centred point of focus, archaeology deals with very complex surfaces and always examines traces of past human presence in three geometrical dimensions. Visualising these detailed geometric environments is not that much of an issue anymore; however, interactively interpreting and mapping them is still problematic. Despite the steady increase in technologies to create 3D models, there is still a serious lack of tools that allow for easy interaction with these models in a metrical and coordinate system-aware environment. As a result, most—if not all—interpretation workflows will first downscale 3D data to two-and-a-half-dimensional (2.5D) or 2D data sets, thus effectively discarding up to one geometrical dimension. To enable or enhance the perception of topographic characteristics in these geometrically compromised datasets, various visualisation techniques have been developed to artificially restore and enhance the data that was initially discarded. While these techniques work very well to enhance the remaining pertinent features present in such data sets, data downscaling can nevertheless irrevocably eliminate significant amounts of important archaeological information. Therefore, this paper outlines a new processing and interpretation pipeline for complex archaeological 3D surfaces that do not rely on downscaling of data, while also discussing several 3D-related concepts and issues along the way. More specifically, this article focusses on the generation of intelligently decimated, two-manifold triangular meshes and the subsequent geo-referenced 3D interpretative mapping of these surfaces. Furthermore, all applications can be considered low- and even no-cost, making this a readily implemented processing and interpretation workflow. Additionally, all software packages are easy to learn and flexible enough for implementation in any existing mixed software pipeline.     

The Nice Musical Chairs Model: Exploring the Role of Competition and Cooperation Between Farming and Herding in the Formation of Land Use Patterns in Arid Afro-Eurasia

Following a strictly theory-building approach, we developed an agent-based simulation model, the Nice Musical Chairs model, to represent the competition between groups of stakeholders of farming and herding activities in the arid Afro-Eurasia. The model deepens the questions raised by the results of our former model, the Musical Chairs model, and further introduces three socio-economic mechanisms, which modulate the behavior and performance of stakeholders and their groups. First, we define land use pairing as the awarding, regarding productivity, of any direct cooperation between farming and herding within a group. Second, group management is modeled as the prerogative of a group leadership to manage stakeholders to pursue a particular proportion between farming and herding. Third, we introduce restricted access to pasture as the engagement in territorial control of rangelands in opposition to an open access regime. An exhaustive exploration of scenarios and parameters placed the control over rangelands as the most significant factor in the formation of land use patterns, followed by land use management. While the effect of land use pairing is mild in comparison, it is still a significant factor in group selection and thus in the persistence of particular land use patterns in the long run.
