Application of Non-Destructive Techniques in the Inspection of Wooden Structures of Protected Buildings: The Case of Nuestra Señora de los Dolores Church (Isla Cristina,Huelva)

This study describes a thorough inspection of a 20th century church in the town of Isla Cristina (in the province of Huelva, southwestern Spain), which is currently awaiting restoration. The study indicates the damage processes at work in the building structure materials (brick, concrete, steel, and wood), which are closely related to its geographical location, and analyses the deterioration of the wooden roof structure. The analysis of the wooden roof includes the results of an inspection methodology on a protected building based on traditional techniques such as visual inspection and innovative non-destructive inspection techniques (visual classification, ultrasounds and thermography). Fieldwork consisted of the visual classification of the wooden pieces according to Spanish standard UNE 56544:2007 specifications after which ultrasound and thermography techniques were applied on-site. A second stage involved laboratory tests (anatomic identification, density and bending strength) using wood samples extracted from the structure in order to check the values for the physical and mechanical properties previously recorded by non-destructive techniques (NDT). These non-destructive techniques are used in inspections of the wooden roofs of buildings to identify dampness, deterioration, density loss and defects as a means of assessing their conservation status. This work concludes that the use of ultrasound and thermography techniques constitute an accurate diagnostic tool for the on-site inspection of wooden structures and the evaluation of their condition. Thermography identifies different materials and moisture content while ultrasound detects the various degrees of deterioration and density-loss in areas of the wood with high moisture content.     

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.     

Methods of Palaeodemography: The Case of the Iberian Oppida and Roman Cities in North‐East Spain

Ancient demography is a recurrent topic in archaeology, thanks to new methods and evidence from different surveys and excavations. However, different cultures or periods are studied on their own, without any comparison being made between them and of their population dynamics. The present paper seeks to advance the situation by defining methodologies to allow diachronic comparisons between two different periods and cultures. After setting out a methodological approach, the paper goes on to apply the same to a case study: namely the Roman conquest of north‐east Spain, comparing the demography of the ancient Iberian communities (fourth‐second centuries BCE) to the Roman colonization (first century BCE to first century CE). Roman urbanism is generally supposed to increase the population in a particular territory, but our present evidence refutes this point: a decrease in population is visible in urban or proto‐urban sites from the Iberian to Roman periods, though there is an increase in the rural densities.     

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.     

The liminality in popular festivals: identity,belonging and hedonism as values of tourist satisfaction

Abstract

A Festa do Boi is a festive celebration linked to the Catholic liturgical calendar, which is celebrated in Allariz (Galicia-Spain). This festival reappears in the 1980s and like other popular festivals, it collects traditional elements and re-builds them into a new festive ritual, more in line with the new temporal and spatial configuration of the late 20th century. They are festivals in which tradition is combined, in representation of the local community, and the tourist approach (Prats, 1997 Prats, L. L. (1997). Antropología y patrimonio. Madrid: Alianza. [Google Scholar]). This event can be analysed as a spontaneous communitas (Turner, 1974a Turner, V. (1974a). Dramas, fields and metaphors. New York: Cornell University Press. [Google Scholar]), a happening between hosts and guests (Smith, 1992 Smith, V. L. (1992). Anfitriones e invitados (Turismo y sociedad). Madrid: Endymion. [Google Scholar]), where the liminal space can be occupied by tourists as ‘others’ necessary for the identification of ‘ourselves’. The participation of tourists in the festive ritual is carried out from two liminal positions: an unstable state because their daily life has been broken by the movement and involvement required in the festivals with the role of equals, but different. Both actors are required for the exaltation of collective identity. The level of satisfaction of tourists with the liminal experience based on the feeling of belonging and identification with the host community and the hedonistic perception, to provide a more holistic view of the festive ritual. A self-administered on-site survey was conducted on 393 tourists attending the 700th edition of A Festa do Boi in Allariz (Spain). The results suggest that hedonism acts as a precedent for satisfaction evaluation, and satisfaction evaluation for the attendees´ future intentions. In addition, the liminal experience has a two-dimensional structure composed of the individual changes experienced and of the festive ritual.     

An overview of Caribbean and Latin-American cultural heritage studies

Abstract

This review analyzes, through three recently published books that talk about cultural heritage in Latin America, how the Cultural Heritage Studies have allowed us to understand the current situation in the region characterized by the growing tendency to promote declarations of heritage as part of a plan for the use of culture as a resource for sustainable development. Likewise, those books analyze how responses from local communities are generated to hegemonic definitions of heritage, which indicates that cultural heritage in Latin America is not something given but something in constant construction and dispute.
