The origin and construction of pre-Hispanic mounds in the Upper Delta of the Paraná River (Argentina)

Pre-Hispanic mounds, known as “cerritos,” “cerritos de indios,” or “aterros” across southeastern South America, are one of the most conspicuous and well-studied cultural manifestations in lowlands archaeology. Nevertheless, in the Upper Delta of the Paraná River, mounds are rarely studied, and even their anthropic origin is under debate. This could be related to the fact that anthropogenic mounds are located on a floodplain where other “mound-like” natural geoforms (generated by fluvial processes) are also present. In addition to this, the natural geoforms also contain evidence of Holocene human occupation (sherds, bones, charcoal, humans burials, etc.), which can lead to interpretive errors of their origin and formation. Thus, this project set out to determine the genesis and evolution of these mounds and also to identify the cultural occupation and transformation of natural landforms found in the area. In this article, natural and anthropogenic systems and processes were identified and characterized through the application of proxy record analysis (i.e., sediment composition, stratigraphy, micromorphology, silica bodies and chronological analysis) at the Los Tres Cerros archaeological locality in the Upper Delta of the Paraná River of Victoria County, Entre Ríos Province, Argentina. This analysis allowed for the recognition of natural anthropogenic interfaces, such as the “pre-mound” occupation as well as evidence of cultural activities such as mound construction, between 1,000 and 500 ¹⁴C years bp. These findings were integrated into current research on the variability of mound construction during the Late Holocene in the lowlands of South America.     

Built environment and tourism as road safety determinants in Benidorm (Spain)

The rise in the number of urban road accidents is a challenge shared by all European cities, which seek to improve mobility while reducing transport problems. In recent years, urban road accidents in Spain have been constantly increasing and now account for a larger share of the total number of road accidents. This paper aims to analyse the impact of urban factors on road accidents. For this purpose, a small-scale analysis of land use and road infrastructure has been conducted in the town of Benidorm, one of the main tourist destinations in Spain. In addition, a regression analysis has been carried out using a Negative Binomial distribution. The results show that factors such as the level of mixed land uses, population density and road infrastructure are related to urban road accidents. The findings also reveal that tourism environments have a positive impact on pedestrian road safety. Small-scale analyses, particularly those related to exclusively-oriented environments, such as tourism developments, should be studied in detail in order to promote safety, liveability and sustainability in our cities.     

Contribution of the resistivity method to characterize mud walls in a very dry region and comparison with GPR

Mud walls are frequent in many archaeological sites, including sites located in semi-desert regions. In cases with buried walls, the geophysical methods can be useful tools for their investigation, since they provide maps of the subsoil in a non-invasive way and in relatively short times. This article deals with the characterization of mud walls in very dry soils through the resistivity method, discussing a methodology to satisfactorily apply the method in this kind of adverse environment and how to interpret the results. The case of the Palo Blanco archaeological site, a pre-Incaic village located in the NW region of Argentina, is analyzed.     

Towards a Multi-Agent-Based Modelling of Obsidian Exchange in the Neolithic Near East

This paper examines an alternative approach to previously proposed models of prehistoric exchange such as the law of monotonic decrement or the down-the-line exchange model developed by Renfrew (Proceedings of the Prehistoric Society 34: 319–331, 1968, Renfrew 1977) to explain the distribution of obsidian across the Near East during the Neolithic period. Renfrew’s down-the-line model, which results in a very regular and clustered network, does not permit the circulation of obsidian to regions of the Near East that are further than 300 km from the source zones, as is shown in the archaeological data available. Obsidian exchange is a complex system where multiple factors interact and evolve in time and space. We therefore explore Agent-Based Modelling (ABM) so as to get a better understanding of complex networks. ABM simulations of an exchange network where some agents (villages) are allowed to attain long-distance exchange partners through correlated random walks are carried out. These simulations show what variables (population density, degree of collaboration between villages…) are relevant for the transfer of obsidian over long distances. Moreover, they show that a type of small-world exchange network could explain the breadth of obsidian distribution (up to 800 km from source) during the Near Eastern Neolithic.     

The Anthropogenic Use of Firewood During the European Middle Pleistocene: Charcoal Evidence from Levels XIII and XI of Bolomor Cave,Eastern Iberia (230–160 ka)

Human control of fire is a widely debated issue in the field of Palaeolithic archaeology, since it involved significant technological innovations for human subsistence. Although fire evidence has been the subject of intense debate regarding its natural or anthropogenic nature, most authors agree that combustion structures represent the most direct evidence of human control of fire. Wood charcoal fragments from these contexts represent the fuel remains that result from humans’ collection of firewood, which means they can reveal significant behavioural and palaeoenvironmental information relevant to our understanding of Middle Palaeolithic societies. In this work, we present anthracological data derived from combustion structure 2 (level XIII, ca. 230?ka, MIS 7) and combustion structure 4 (level XI, ca. 160?ka, MIS 6) from Bolomor Cave, which are chronologically among the earliest combustion structures found in Europe. The present work discusses how the presence of black pine and / or scots pine in both levels sheds light on the characterisation of the local landscape. Additional analyses focussing on the pre- and post-depositional processes affecting charcoal preservation point to biodegradation patterns. The aim of this work is to provide the first discussion concerning the anthracological data derived from Bolomor Cave in order to contribute to the general debate regarding the use of fire during the European Middle Pleistocene.     

Terrestrial laser scanning and close range photogrammetry for 3D archaeological documentation: the Upper Palaeolithic Cave of Parpalló as a case study

Graphic and metric archaeological documentation is an activity that requires the capture of information from different sources, accurate processing and comprehensive analysis. If monitoring of the state of conservation is required, this task has to be performed before intervention, during and after the completion of the works in a repetitive way.This paper presents the use of terrestrial laser scanning (TLS) in order to effectively produce, prior to intervention, accurate and high-resolution 3D models of a cave with engravings dating back to the Upper Palaeolithic era. The processing of the TLS data is discussed in detail in order to create digital surface models. The complexity of the cave required the integration of two techniques, TLS and close range photogrammetry to yield not only traditional drawings such as sections and elevations, but also photo-realistic perspective views and visual navigation worlds fully operational in 3D environments. This paper demonstrates the potential of integrating TLS and close range photogrammetry to provide both accurate digital surface models and photo-realistic outputs. This processed data can be used to systematically improve archaeological understanding of complex caves and relief panels of prehistoric art with tiny engravings.     

Firing technique characterization of black-slipped pottery in Praeneste by low field 2D NMR relaxometry

This study was aimed at individuating characteristics related to the pottery’s firing technique of Classical Roman producers, through the low field single-sided NMR relaxometry. The approach is based on a recent method of analysis, the correlation of the longitudinal and transverse NMR relaxation times of a liquid probe (in this case distilled water) filling the porous system of ceramics. The analyzed findings form two homogeneous classes with dating and place of production well established through the producer trademarks. Pottery findings belong to the black-slipped pottery productions of the Latin ancient city of Praeneste between third and second century B.C. and have been attributed to two different ”patriziae” production families: gens Samiaria and gens Trebonia. A further fragment with Greek kylix style, found in the same archaeological area, has also been analyzed, in order to understand if it had been imported from Greece, or made in Praeneste in imitation of the Greek style.     

Commons and the construction of power in the early Middle Ages: tenth-century León and Castile

ABSTRACT

This article examines the role played by the control of common lands (commons) in the configuration of power in the northern Iberian Peninsula during the early Middle Ages. Although there were marked differences between them, the kings of León and the counts of Castile consolidated their power over local society by guaranteeing the defence and correct management of commons. Their example provides the basis for this study, which investigates whether these higher levels of commons protection and management could have been a way of building and consolidating power (whether as lords, royalty, counts, or in urban areas) during the Middle Ages.
