Assessing the macrofracture method for identifying Stone Age hunting weaponry

Macrofracture analysis is an experimentally derived method used as an initial step in investigating the hunting function of stone artefacts. Diagnostic impact fractures, which can only develop as a result of longitudinal impact, underpin this method. Macrofracture analysis recently gained favour in Middle Stone Age studies, supporting hypotheses for effective hunting during the late Pleistocene in southern Africa. However, the factors affecting diagnostic impact fracture formation and the interpretation of these fracture frequencies are not yet fully understood. This paper outlines a set of experiments designed to test macrofracture formation under human and cattle trampling and knapping conditions. The results show that: (a) macrofractures occur frequently when stone artefacts are trampled by cattle and humans and in knapping debris; (b) diagnostic impact fractures occur on some of the trampled flakes and knapping debris (≤3%), but significantly less often than in previous hunting experiments; (c) when they do occur, they are likely produced by longitudinal forces similar to those experienced during hunting; (d) considering artefact morphology is important during macrofracture analysis; and (e) macrofracture analysis is not a standalone method, but is most useful as part of a multi-analytical approach to functional analysis. These experiments help to establish a significant baseline diagnostic impact fracture frequency for the interpretation of archaeological macrofracture frequencies.     

Experimental insights into alternative strategies of lithic heat treatment

Conditions in which thermal fractures occur are explored experimentally, and the results are used to assess heat treatment strategies. We conclude that no single ‘critical temperature’ for thermal fracturing or heat treatment can be specified for any particular raw material, as has so often been attempted, because threshold temperatures exist in relationship to specimen sizes. Our experiments show that smaller specimens are resilient to greater ranges of temperature fluctuations than larger ones, and that by manufacturing/selecting specimens of smaller sizes there is more potential to heat them rapidly and to higher temperatures without producing thermal fractures. We hypothesize a continuum of heat treating strategies between a ‘slow and steady’ strategy, which has overwhelmingly dominated past experimental designs, and a ‘fast’ strategy, which has received much less attention. The paper discusses the economic and technological contexts to which different heat treating strategies might be suited.     

The effects of Class I and II sized bovids on macrofracture formation and tool displacement: Results of a trampling experiment in a southern African Stone Age context

Abstract

In this paper we follow from previous experiments that assessed the formation of macrofractures on hunting weapons and trampled tools, and present the results of a new trampling experiment. This new experiment examined the relationship between small bovid trampling and the formation of macrofracture types on replicated stone and bone tools. We also recorded the resulting displacement of the tools in order to assess the relationship between tool morphology and displacement. Three tool types with dimensions similar to southern African archaeological tools were used. The results suggest that small frequencies of certain impact macrofractures occur on tools subject to trampling forces. These frequencies are, however, lower than those generally recorded during hunting experiments. Tool morphologies and fracture combinations are also shown to be important variables in macrofracture analyses. These results contribute to a growing body of experimental data dealing with the relationship between postdepositional processes and macrofracture formation on artifacts.     

The development of the longbow in late medieval England and ‘technological determinism’

Traditional understandings of the development of the medieval English longbow and its role in the fourteenth-century ‘infantry revolution’ have recently been challenged by historians. This article responds to the revisionists, arguing based on archaeological, iconographic and textual evidence that the proper longbow was a weapon of extraordinary power, and was qualitatively different from – and more effective than – the shorter self-bows that were the norm in England (and western Europe generally) before the fourteenth century. It is further argued that acknowledging the importance of the weapon as a necessary element of any credible explanation of English military successes in the era of the Hundred Years War does not constitute ‘technological determinism’.     

Correlating archaeological and palaeoenvironmental records using a Bayesian approach: a case study from Sutton Common,South Yorkshire,England

This paper presents a case study aimed at correlating archaeological ‘events’ (obtained from radiocarbon measurements and dendrochronology) from the site of Sutton Common with a radiocarbon-dated pollen sequence obtained from a palaeochannel deposit adjacent to the area of the main archaeological activity. It demonstrates the use of a Bayesian approach to quantifying whether the timing of palynological ‘events’ interpreted as reflecting anthropogenic impacts are likely to be associated with archaeological ‘events’. The results suggest that Bronze Age activity in the form of a mortuary enclosure and associated cremation burials are probably not contemporary with the palynological evidence for disturbance to the oak–hazel woodland in this period. Subsequent evidence for local woodland clearance and agriculture is estimated to precede the construction of the large Iron Age enclosure in 372 BC, with increases in ‘anthropogenic indicators’ following this ‘event’. The construction of the site does not appear to have had a pronounced impact on the local vegetation, with hazel the only woody taxon to show clear reductions. Despite the use of a substantial number of oak timbers in the enclosure palisade, percentages of oak remain remarkably stable. Later farming activity on the site probably post-dates the end of activity in the enclosures. The value of the methodology is discussed in relation to quantifiable and robust correlations of archaeological and palaeoenvironmental narratives of landscape and human activity.     

Counterfactual geographies: worlds that might have been

This paper argues for a renewed consideration of counterfactuals within geography. Drawing upon Doreen Massey's emphasis on notions of ‘possibility’, ‘chance’, ‘undecidability’ and ‘happenstance’, we argue for an engagement with approaches in the humanities that have addressed such issues directly. We review previous uses of counterfactual method in historical geography, particularly as related to cliometrics and the ‘new economic history’ of the 1960s, but argue that a recent upsurge of interest in other disciplines indicates alternative ways that ‘what-if’ experiments might work in the sub-discipline. Recent counterfactual work outside of geography has had a notably spatial cast, often thinking through the nature of alternative worlds, or using counterfactual strategies that are explicitly concerned with space as well as temporal causality. We set out possible agendas for counterfactual work in historical geography. These include: consideration of the historical geographies within existing counterfactual writings and analyses; suggestions for distinctive ways that historical geographers might think and write counterfactually, including experiments in geographies of happenstance, and the exploration of more-than-human possibilities; analyses of the geography of and in counterfactual writing; and study of the political, ethical and emotional demands that counterfactuals make. This discussion and framework provides an extended introduction to this special feature on counterfactual geographies.     

Ancient-DNA reveals an Asian type of Mycobacterium leprae in medieval Scandinavia

Leprosy is a chronic infection of the skin and peripheral nerves caused by the pathogen Mycobacterium leprae. Its impact on human populations and societies of the past as well as its phylogeographic patterns around the world – at least in modern times – has been well documented. This slow growing bacterium has been shown to exist in distinct ‘SNP types’ that occur in relatively defined parts of the globe. The routes that the disease followed in the past are, however, still uncertain. This study of ancient-DNA typing of archaeological human remains from Sweden dated to early Medieval times provides genetic evidence that a transmission of M. leprae ‘SNP subtype’ 2G – found mainly in Asia – took or had already taken place at that time from the Middle East to Scandinavia. This finding is unique in the history of leprosy in Europe. All human specimens from this continent – both modern and ancient – that have been tested to date showed that the one responsible for the infection strains of M. leprae belong to ‘SNP type’ 3, whereas our results show that there were some European populations that were hosts to bacteria representing ‘SNP type’ 2 of the species as well.     

Interrogating post-democratization: Reclaiming egalitarian political spaces

There is now an emerging body of thought on the dynamics of de-politicization, the ‘disappearance of the political’, the erosion of democracy and of the public sphere, and the contested emergence of a post-political or post-democratic socio-spatial configuration. I situate and explore this alleged ‘post-democratization’ in light of recent post-Althusserian political thought. I proceed in four steps. First, I discuss the contested configurations of this post-politicization and the processes of post-democratization. In a second part, I propose a series of theoretical and political arguments that help frame the evacuation of the properly political from the spaces of post-democratic policy negotiation. This diagnostic is related to a particular interpretation of the distinction between ‘the political’ and ‘polic(e)y/‘politics’. In a third part, I argue how emancipatory–democratic politics can be reclaimed around notions of equality, and freedom. In the concluding part, perspectives for re-vitalising the political possibilities of a spatialized emancipatory project are presented. The crux of the argument unfolds the tension between politics, which is always specific, particular, and ‘local’ on the one hand and the universal procedure of the democratic political that operates under the signifiers of equality and freedom on the other.     

Contextualist dilemmas: Methodology of the history of political theory in two stages

This article traces the development of contextualist methodology in the study of the history of political thought/political theory after WWII. It argues that the so-called ‘Cambridge School’, often regarded as the core of historicist contextualism, arose during the 1950s and 1960s in response to dilemmas that were largely internal to (the history of) political philosophy as it was practiced in Britain in an academic culture dominated by analytic philosophy. This first stage of contextualist theorizing, usually associated with Laslett, Skinner and Pocock, was highly influential, but it also contributed to the formation of a new set of problems. These were connected to the diversification and internationalization of the historicist contextualist study of political thought after the 1960s. The ‘second stage’ of contextualist theorizing was shaped by post-analytic and post-modernist impulses among others. Because of the variety of philosophical and conceptual commitments on notions central to the field such as ‘political thinking’, ‘politics’, or ‘power’, it is unlikely that the present historicist contextualist approaches would come to share a unified methodology or theory of historical interpretation.     

The ‘walking’ megalithic statues (moai) of Easter Island

Explaining how the monumental statues (moai) of Easter Island were transported has remained open to debate and speculation, including their resource expenditures and role in deforestation. Archaeological evidence including analysis of moai variability, particularly those abandoned along ancient roads, indicates transport was achieved in a vertical position. To test this proposition we constructed a precise three-dimensional 4.35 metric ton replica of an actual statue and demonstrate how positioning the center of mass allowed it to fall forward and rock from side to side causing it to ‘walk.’ Our experiments reveal how the statue form was engineered for efficient transport by a small number of individuals.     

Hunting with Howiesons Poort segments: pilot experimental study and the functional interpretation of archaeological tools

For many decades the use of backed pieces from the Howiesons Poort, between about 70 ka and 55 ka ago, in South Africa has been a point of discussion. Recently direct evidence has been provided to associate these tools with Middle Stone Age hunting strategies. Yet, whether they were used to tip hunting weapons or as barbs remained an open question. In this paper we introduce a set of pilot experiments designed to test the effectiveness of Howiesons Poort segments, the type fossils of the industry, hafted in four different configurations as tips for hunting weapons. It is shown that the morphological type can be used successfully in this way. We present the results of a macrofracture analysis conducted on the experimental tools and compare these to results obtained from three Howiesons Poort backed tool samples. By correlating experimental outcomes, macrofracture data and the interpretation of micro-residue distribution patterns, we provide some insight into the functional variables that might be associated with Howiesons Poort segments.     

Trapeze shaped flint tips as proxy data for occupation during the Late Mesolithic and the Early to Middle Neolithic in the northern part of the Netherlands

In the northern part of the Netherlands (defined here as the area situated above the river Rhine), the Late Mesolithic is dated to the period between ca. 8100 and 6000 BP, and is characterised by the occurrence of trapeze shaped flint tips. Trapezes continue to be in use during the Swifterbant culture (ca. 6000–4800 BP), including the ceramic Mesolithic phase (Early Swifterbant) which is dated between 6000 and 5600 BP. During the Funnelbeaker culture or TRB (ca. 4800–4100 BP) transverse points dominate. With the onset of the Single Grave Culture (SGC) transverse points are no longer the ‘preferred weapon of choice’; they are replaced by surface-retouched (tanged) points. In this paper some of the basic premises of the typological development of trapezes (narrow to broad) and the chronological relevance of ‘subtypes’ (symmetric, asymmetric, right-angled and rhombic) are discussed based on analyses of trapezes from four excavated Mesolithic and Swifterbant sites. For comparison a random sample of TRB transverse points was included in several analyses as well. One of the main conclusions of this paper is that it is possible, based on analyses of metric and non-metric traits of trapeze shaped flint tips, to distinguish between true ‘Mesolithic’ trapezes, trapezes belonging to the (Neolithic) Swifterbant culture, and transverse points of the TRB. The outcomes of these analyses may help in obtaining a relative date for undated (surface) assemblages, and may furthermore lead to the positive identification of Swifterbant settlements in the higher (situated above the present-day sea level) Pleistocene areas in the northern and eastern part of the study area which are so far unknown. The results presented here will be put to the test in a forthcoming paper.     

Technology based evolution? A biometric test of the effects of handsize versus tool form on efficiency in an experimental cutting task

The use of stone cutting tools opened a novel adaptive niche for hominins. Hence, it has been hypothesised that biomechanical adaptations evolved to maximise efficiency when using such tools. Here, we test experimentally whether biometric variation influences the efficiency of simple cutting tools (n = 60 participants). Grip strength and handsize were measured in each participant. 30 participants used flint flakes, while the other 30 used small (unhafted) steel blades. Variations in basic parameters of tool form (length, width, thickness, cutting edge length) were recorded for the 30 flint flakes. It was ensured that mean handsize and strength in each participant group were not significantly different to investigate the effect of tool variation. The experimental task required cutting through a 10 mm-diameter hessian rope. Cutting efficiency was measured using both ‘Number of cutting strokes required’ and ‘Total time taken’. Results show that both efficiency measures were significantly correlated with handsize using all 60 participants. However, no significant differences were found between the flake and blade groups in terms of mean efficiency. Nor was any significant relationship found between tool form parameters and efficiency in the flint flake group. We stress that our results do not imply that tool form has no impact on tool efficiency, but rather that – all other things being equal – biometric variation has a statistically significant influence on efficiency variation when using simple cutting tools. These results demonstrate that biomechanical parameters related directly to efficiency of use, may plausibly have been subject to selection in the earliest stone tool-using hominins.     

A review of rock art dating in the Kimberley, Western Australia

This paper critically reviews the various approaches used to estimate the age of the rock art in the Kimberley region of Western Australia. They include: (i) the relative superimposition of styles; (ii) the use of diagnostic subject matter (depictions of extinct animals, stone tool technology, introduced European and Asian objects and animals); (iii) the recovery of a ‘painted’ slab from a dated archaeological unit; (iv) radiocarbon dating of beeswax figures, charcoal pigments, organic matter in overlying mineral deposits and ‘accreted paint layers’ (oxalate rich crusts and amorphous silica skin), pollen grains from an overlaying mud-wasp nest; and (v) optically stimulated luminescence (OSL) dating of quartz grains from overlying mud-wasp nests. Future directions for rock art dating in the Kimberley include uranium-series dating of overlying and underlying mineral deposits.     

Processing ochre in the Middle Stone Age: Testing the inference of prehistoric behaviours from actualistically derived experimental data

The increase in the presence of ‘ochre’ in African Middle Stone Age contexts has been employed, together with changes in human biology and behaviour, to support the hypothesis that ‘modern’ cognitive abilities arose in Africa. The consistent exploitation of ochre is interpreted as evidence for colour symbolism, a proxy for the origin of language and a defining aspect of ‘modern’ human behaviour. That humans attached considerable symbolic value to red ochres in particular is illustrated by ethnographic examples. Research has shown that wear patterns indicative of abrasive processing methods prevail, but many archaeological specimens also exhibit wear traces not derived from grinding or scraping alone. Building on former research, I present here the results of an experimental study devised to infer the methods employed to extract powder from ochre during the African Middle Stone Age. The prospect of ascertaining at least some of the likely uses to which ochre may have been put, is also explored. I conclude that functional data derived from actualistic experiments can be used to enhance our understanding of some aspects of prehistoric behaviour.     

The institutionalisation of ‘colonial geography’ in France, 1880-1940

Between 1880 and 1900, the conjunction of the development of higher education in France with the renewal of colonial expansion resulted in the creation of the ‘colonial sciences’. ‘Colonial geography’ played a key role in the development of these new disciplines, alongside ‘colonial history’, ‘ethnology’, ‘colonial economics and legislation’ and ‘colonial psychology’. This paper considers the social history of this field and of the institutions in which colonial geography was formed. This involves examination of the study of the teaching of ‘colonial geography’ in the universities and French grandes écoles, the gradual professionalisation of scholarship, and the increase in the number of doctoral theses and book publications, which all serve to demonstrate the vigour of the subdiscipline, leading to the emergence of a veritable research community. Under the Third Republic, ‘colonial geography’ in the universities was characterised by great diversity, irreducible to a single or homogenous ‘colonial discourse’.     

Post-Enlightenment sources of political authority: Biblical atheism, political theology and the Schmitt-Strauss exchange

This essay reevaluates the Weimar writings of Carl Schmitt and Leo Strauss, specifically, their intellectual efforts to replace the political authority of Kantian liberalism with, respectively, a ‘political theology’ and ‘Biblical atheism’ derived from the thought of early-modern state theorists like Hobbes and Spinoza. Schmitt and Strauss each insisted that post-Kantian Enlightenment rationality was unraveling into a way of thinking that violently rejected ‘form’ of any kind, fixated myopically on material things and lacked any conception of the external constraints that invariably condition the possibilities of philosophy, morality and politics. They considered Kantian reason and liberal politics to pose serious threats to ‘genuine’ expressions of rationality and as dangerous obfuscations of the necessity of political order—of the brute fact that human beings stand in need of ‘being ruled,’ as such.     

War and peace? An agenda for peace research and practice in geography

In 1885, Kropotkin called for geography to be ‘a means of dissipating [hostile] prejudices’ between nations that make conflicts more likely, and ‘creating other feelings more worthy of humanity’. As a body of scholars, we have risen far more ably to the negative task of ‘dissipating’ than to the positive charge of ‘creating’: Geography is better at researching war than peace. To redress that imbalance, we need both to conceptualise more clearly what we mean by peace, and make a commitment to researching and practising it. These arguments are made with reference to the broader literature and research along the Danish/German, Israeli/Palestinian and Kyrgyz/Uzbek interfaces.     

The gravity model: monitoring the formation and development of the Tripolye culture giant-settlements in Ukraine

The formation, development and decline of the Tripolye culture giant-settlements in Chalcolitic Ukraine are strictly linked to complex processes of migration and settlement relocation. Despite being traceable through pottery typological analyses linked to contextual seriations, their identification is sometime not obvious. This paper shows how the application of the ‘gravity model’ not only facilitates their recognition, but it also helps increase the reliability of determining diachronic and/or synchronic occupations, shedding at the same time light upon the crucial ‘internal’ development of single settlements. Instead of clear-cut consecutive occupations, a more gradual settlement rotation with some synchronous phases seems to have prevailed.     

Trauma in the Crusader period city of Caesarea: a major port in the medieval eastern Mediterranean

Caesarea is the first fortified city to undergo palaeopathological analysis of its Crusader period inhabitants. This study of the 12th and 13th century population aims to determine the major types of trauma present, whether from weapon injuries or accidents. Since the Crusades were known for the significant number of battles and raids that took place, weapon injuries were expected to be common. Thirteen cases of trauma are described and a highly unexpected pattern has come to light. These cases do not include one single example of weapon‐related trauma. Every fracture is of a type expected from accidents or interpersonal violence without weapons. Possible explanations include the location of the city deep within Frankish territory and the robust city walls giving effective protection to the inhabitants, and also that the population were involved in activities that left them prone to accidents but not weapon injuries. The other important finding from this study was that the cases of lower limb long bone spiral fractures had healed in a near‐anatomical alignment. This is not what we would expect, as a proportion of these injuries would normally have been unstable and tend to heal poorly aligned. The good position could have resulted from surgeons' use of splints to immobilise the bones while they healed. This suggestion is supported by laws of the kingdom of Jerusalem, which stated that surgeons were to be punished if they allowed such fractures to heal at an angle.
