Static penetration assessment of stone weapon tip geometry metrics and comparison of static and dynamic penetration depths

Many factors governed the penetration efficacy of prehistoric projectile weaponry. Archaeologists broadly focus their efforts on understanding the effect of stone weapon tips because these specimens are often the only part of the weapon system that survives in the archaeological record. The tip cross-sectional area (TCSA) and perimeter (TCSP) of stone weapon tips have been shown to correlate with target penetration depth. Here, using results from both static and dynamic penetration testing, we compare TCSA and TCSP against other tip geometry metrics: lateral surface area (LSA) and volume (V). Our analyses broadly show that using a single-point geometry metric evaluated at multiple locations along the length of the point, or using multiple geometry metrics evaluated at a single location, better predicts required energy than using a single-point geometry metric evaluated at a single location. Our results also show that in the case where a single geometry metric evaluated at multiple locations is used LSA provided the most robust prediction models. Finally, our results show that for the case where all geometry metrics evaluated at a single location are used the location that provides the most robust prediction model is dependent on how far the point penetrated the target.     

Twelfth-century Italian confraternities as institutions of pastoral care

When studied through canon law and scholastic pastoralia produced in the universities in the thirteenth century and beyond, medieval pastoral care comes across as spiritual care, more specifically the administration of sacraments and preaching, provided by the clergy for the faithful. This article complicates that view by arguing that in the twelfth century, the laity alongside the clergy was active in the provision and organisation of pastoral care. The sources examined are the surviving statutes of five religious confraternities – along with the obituaries and sermons in two cases – in Italy that flourished in the twelfth century and before. Each of these confraternities was centred around a church, established after an apostolic ideal, included laymen and women and local pastoral clergy of all levels, met regularly to celebrate the Eucharist, prayed for the dead members and made public confessions. Members prayed for and attended to the corporal needs of each other in case of sickness. In the final analysis, these twelfth-century confraternities appear as transitional institutions between the early medieval monastic confraternities focusing on prayer and the late medieval and renaissance confraternities focusing on charity. Their study opens a window onto the lay expectations of and contribution to pastoral care in medieval Italy.     

Kuhn's Geometric Index of Unifacial Stone Tool Reduction (GIUR): does it measure missing flake mass?

Kuhn's GIUR is a set of measurements taken on a resharpened stone flake's edge. Its purpose is to estimate the amount of stone removed before the exhausted tool was abandoned. An experimental test of Kuhn's Index led Hiscock and Clarkson to suggest that it is an excellent estimator of flake mass loss. Our own tests, using different experimental procedures, reached much less optimistic conclusions. Here, we apply their own measurement procedures, and successfully duplicate their results. It does not follow, however, that our now-consistently high correlations have a causal connection. As GIUR values increase, they are less able to estimate the actual loss of flake mass. It appears, therefore, that incremental loss of flake mass need not be the sole driver of the GIUR value. If the correlation is an inevitable byproduct of the experiment's design, as it now appears, then analyses based on this high correlation will be misleading. The GIUR remains, however, and excellent gauge of flake edge exhaustion.     

New evidence of adhesive as hafting material on Middle and Upper Palaeolithic artefacts from Gura Cheii-Râşnov Cave (Romania)

Making use of analytical, chemical and mineralogical methods, this paper focuses on the analysis of inclusions in order to address the question of the provenance of prehistoric artefacts excavated in Gura Cheii-Râ?nov Cave (Romania). The study represents the first discovery of bitumen on lithic tools belonging to the Upper and Middle Palaeolithic in Europe. The material was identified through several analytical procedures, such as Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray fluorescence (EDXRF), inductively coupled plasma atomic emission spectroscopy (ICP-AES), and X-ray diffraction (XRD).     

Staging the Transnistrian Identity Within the Heritage of Soviet Holidays

This article focuses on the performance of three national holidays in Transnistria in the context of the ongoing consolidation of Transnistrian society since 1991. Transnistrian leaders play a key role in the construction of a distinct Transnistrian regional identity; hence this paper pays close attention to the speeches of Transnistrian leaders as reported in the mass media. In addition, I also base my conclusions on interviews with the residents of Rybnita. I was able to observe and describe the official commemorations of the anniversary of the October Revolution, May Day and Victory Day, all key Soviet holidays which are still celebrated in Transnistria, mostly by the older generation and members of the Communist Party. The theoretical framework of the article, therefore, relies on a constructivist approach to the nation-building process through the manipulation of public opinion by elites.     

An empirical test of the relative frequency of bipolar reduction in Beds VI,V, and III at Mumba Rockshelter,Tanzania: implications for the East African Middle to Late Stone Age transition

Mumba Rockshelter, Tanzania, is the only East African site spanning a continuous record of more than 100,000 years, including the Middle Stone Age (MSA) to Late Stone Age (LSA) Transition. Rather than examine the presence or absence of traditional markers of “behavioral modernity”, we have endeavored here to respond to the calls of Shea (2011) and Basell (2008) by examining the proportional similarity of a trait present throughout the MSA–LSA sequence at Mumba Rockshelter: the bipolar technique of lithic reduction. We use a quantified, experimentally derived proxy to track the relative amount of bipolar percussion among Mumba's Beds VI, V, and III, namely, waste shatter. Our examination of Mehlman's previously unanalyzed collections from Mumba demonstrates that in terms of bipolar production Bed V is statistically indistinguishable from the Late Stone Age (LSA) Bed III, but significantly different from the Middle Stone Age (MSA) Bed VI. Given that Bed V dates to 56.9 ± 4.8 − 49.1 ± 4.3 ka cal BP, this result is consistent with other evidence that the origins of the LSA in East Africa began well before 40 kya, and that Mumba Bed V represents one of the earliest manifestations of the LSA in East Africa. We conclude with a discussion of factors that may have influenced the increased dependence of bipolar production at the site.     

From home to city: gender segregation,homosociality and publicness in Istanbul

This article examines the complex and tangled relationships between home, city, and gender in Bagcilar, a municipality in Istanbul governed by Islamist-oriented political parties since 1992. Focusing on women’s spatial experiences at the intersection of the private and the public, the traditional and the modern, the secular and the religious, this article argues that home provides a medium through which gendered forms of governance and publicness are produced in the city. Home as a domestic sphere confines women’s roles to those of motherhood and wifehood, but also functions as a place of sociability for women. The municipality’s Islamic political discourse, combined with secular urban practices, mobilizes women through familial norms, gender-segregated events, and women-only sites in Bagcilar, where home and urban space are mutually constructed, regulated, and legitimized. Thus, women’s publicness, which derives from but goes beyond domesticity, also enables intimate same-sex sociality in urban spaces. Although this creates only conditional access to the city for women, their agency and engagement with the city emanate from such publicness.     

History and Characteristics of Construction Techniques Used in Traditional Timber Ottoman Houses

The aim of this article is to make a comprehensive review of the traditional timber house constructions in Turkey, which constitutes the majority of the existing Ottoman architectural legacy. After a short historical background focused on the Ottoman territory, the first section explores regional differences in the housing tradition, developed according to local features and defined by architectural features, material characteristics, and availability of materials. Derived from these regional differences, in the second section diversity in traditional timber construction systems in Turkey is described with special emphasis on the Ottoman h?m?? system. In this part, besides the discussion of the h?m?? technique which spread over Ottoman lands from the Balkans to Syria, the timber masonry and frame systems of the Eastern Black Sea Region and Thrace are presented in detail with visual support.     

Decay of Limestone Statues at Mount Nemrut (Adiyaman,Turkey)

Mount Nemrut is a 2,206 m high mountain located in Adiyaman, Turkey. A number of monumental statues, a 50-m high tumulus, and a lion horoscope were constructed at the top of the mountain by King Antiochos I (69–36 bc) of the Commagene Kingdom. The site was included in the UNESCO World Heritage List in 1987 due to its unique character. However, the limestone statues located on both the east and the west terraces of the site are getting deteriorated. This study investigates the weathering of the limestone at Mount Nemrut based on field and laboratory studies. It is found that the dissolution occurs along microcracks developed in the limestone during geological time. It is more pronounced in the east terrace where freezing-thawing cycles are more than the west terrace. Furthermore, dissolution is more effective for the faces of the statues exposed to direct atmospheric contact. Due to harsh atmospheric conditions with dominant wetting-drying and freezing-thawing processes at the site, it is recommended that direct rain and snow contact with the statues should be minimized.     

Comparison of four ballistic and thrusting target materials: An experimental and Bayesian approach using static testing of stone and steel arrow tips

Researchers use a variety of target materials, and sometimes combinations of materials, in their archaeological experiments to examine thrust-spear or projectile penetration, impact angle, durability, and other issues involving prehistoric hunting weaponry. This variety of target materials is beneficial to archaeological science in several ways, but it may also hinder the comparison of results because many of these target materials do not necessarily share similar physical properties. Here, we assess the penetration properties of four different target materials—store-bought meat, clay, and two types of gelatin—via static penetration tests of a modern broadhead-tipped arrow and a stone-tipped projectile attached to an Instron Universal Materials Tester. Our analyses of load-deflection curves, peak load, and work energy demonstrate how the four target materials are similar in some ways but different in others, which suggests that researchers may strategically employ one or several depending on the question asked or hypothesis tested.
