Courtyard Houses and Other Complex Buildings in the Protohistory of Southern Gaul: From Architectural to Social Changes

Courtyard houses are attested at several sites in southern Gaul between the 5th and the 1st centuries BC. They represent a new concept when compared to the traditional protohistoric houses of the region and have often been interpreted in terms of Mediterranean, Greek or Italic influences. Regardless of their origin, exogenous influences or evolution, these houses suggest the emergence of social differentiation and elites in several of the main settlements. This article analyses the significance of the various courtyard house categories in the context of local, indigenous societies, while trying to understand the social implications of this new type of residence. In a wider context, the development of domestic architecture during the Iron Age is analysed alongside the relationships between changing uses of space and social changes.

L’assalt de l’aristocràcia gal•loromana al poder episcopal (darrer quart del s. IV-primer quart del s. VI): estratègies de persuasió social i controvèrsies doctrinals derivades de les interpretacions aristocratitzants de la comunitat cristiana

Estudi realitzat a partir d’una estada al Laboratoire d’études sur les monothéismes (UMR 8584, Centre national de la recherche scientifique / École pratique des hautes études / Université Paris IV-Sorbonne), França, entre 2010 i 2011. Anàlisi de la crisi estructural que afectà a l’església gal•la entre el darrer quart del segle IV i el primer del segle VI, crisi causada per la cristianització a gran escala de les elits aristocràtiques gal•loromanes i per la reivindicació per part d’aquest estament de la translació a l’esfera de la jerarquia institucional de l’Església de la seva preeminència econòmica i social. Aquest procés implicà l’aparició d’algunes interpretacions del “fet existencial cristià” que tractaven de legitimar en el plànol teòric la presa del control de les comunitats cristianes per part de la noblesa senatorial. En relació a aquest últim punt, s’ha donat particular rellevància a l’anomenada “controvèrsia semipelagiana” a Provença, amb especial èmfasi en dos punts: a) la relació entre l’oposició a la teologia agustiniana de la gràcia en alguns cercles monàstics provençals –Marsella, Lérins– i l’emergència en aquests ambients d’una literatura autobiogràfica en la que la reflexió sobre els conceptes de uocatio divina i conuersio a l’ascetisme cristià està estretament vinculada a un esforç teòric de redefinició i reorientació de l’ethos aristocràtic; i b) la relació entre els punts teològics debatuts en aquesta controvèrsia i les concepcions eclesiològiques dels pensadors que hi prengueren part –entengui’s aquí per eclesiologia la definició teòrica dels límits i dels fonaments de la “comunitat cristiana”, amb especial incidència en aquest cas en els plantejaments sobre el rol que l’aristòcrata havia d’exercir en aquestes noves comunitats “transversals”–. Aquest projecte bianual ha posat de manifest la inexistència d’una “teologia semipelagiana”, ateses les antagòniques concepcions eclesiològiques dels autors tradicionalment associats a aquesta corrent de pensament: Cassià entén la comunitat cristiana com una elit ascètica en la que els criteris “laics” d’estratificació social queden suspesos, i rebutja –en la teoria i en la pràctica– que aquesta elit hagi d’assumir el lideratge de la comunitat de fidels seglars; en els autors del cercle de Lérins, en canvi, l’oposició a la teologia agustiniana de la gràcia és inspirada per l’esforç d’importar a tota la comunitat cristiana els ideals monàstics, quelcom que fou també una via de legitimació de l’autoritat dels monjos-bisbes d’origen aristocràtic sorgits del cenobi de Lérins.

Settlement evolution, field systems and sedimentary processes in a Mediterranean mid-mountain (Montseny Massif, Catalunya)

This paper presents the first results of a current research project about human – environmental interactions in the Montseny Massif. Our work sets out to integrate two research lines in the studied area: - Archaeological and archaeo-morphological surveys in a lower part of the mountains in order to characterize the evolution of the settlements and field systems. - The geological and geomorphological characterization of the slope and terrace deposits in relation with field systems and archaeological data. First results point out the intensive occupation of these inland areas during the Iberian and the Roman periods. Post-Roman sediments show different processes of erosion.

Analcime crystallization and compositional profiles - Comparing approaches to detect post-depositional alterations in archaeological pottery

The approaches of comparative studies and profile measurements, often used in order to detect post-depositional alterations of ceramics, have been applied simultaneously to two sets of Roman pottery, both of which include altered individuals. As analytical techniques, Neutron Activation Analysis and X-Ray Diffraction have been used. Both approaches lead to substantially different results. This shows that they detect different levels of alteration and should complement each other rather than being used exclusively. For the special process of a glassy phase decomposition followed by a crystallization of the Na-zeolite analcime, the results suggest that it changes high-fired calcareous pottery rapidly, and so fundamentally that the results of various archaeometric techniques can be severely disturbed.

A contribution to the study of post-depositional alterations of pottery using TL dating analysis

In luminescence dating, the potassium concentration significantly contributes to the dose rate value in the age estimation. Within this study, fine-grain thermoluminescence dating has been applied on sherds of calcareous pottery of known age, excavated at a Roman site in Mallorca, Spain. For those of the samples that showed signs of severe potassium leaching, according to chemical and mineralogical examination, the thermoluminescence analysis provided overestimated dates. By using the known archaeological age of the samples, a corrected dose rate value can be estimated which provides the potassium concentration averaged for the burial period. Finally, a step-like model can then be used to estimate the fraction of the burial period after which most of the alteration effects took place.

Photographic rectification of the graphic documentation of historical and archaeological heritage: The case of the southern facade of the Praetorium tower in Tarragona (Tarraco, Hispania Citerior)

This article details the use of photographic rectification as support for the graphic documentation of historical and archaeological heritage and specifically the southern facade of the Torre del Pretori (Praetorium Tower) in Tarragona. The Praetorium Tower is part of a larger monumental complex and one of the towers that connected different parts of the Tarraco Provincial Forum, the politic-administrative centre of the ancient capital of Hispania Citerioris. It is therefore a valuable example of the evolution of Roman urban architecture. The aim of this project is to provide accurate graphic documentation of the structure to facilitate the restoration and conservation of the tower, as well as to provide a more profound architectural and archaeological understanding of the Roman forum. The use of photographic rectification enabled us to overcome the spatial and time difficulties involved in collecting data caused by the size and location of the building. Specific software made it easier to obtain accurate two-dimensional images. For this reason, in our case, photographic rectification helped us to make a direct analysis of the monument and facilitated interpretation of the architectural stratigraphy. We currently separate the line of research into two concepts: the construction processes and the architecture of the building. The documentation collected permitted various analyses: the characterisation of the building modules, identification of the tools used to work the building materials, etc. In conclusion, the use of orthoimages is a powerful tool that permits the systematic study of a Roman building that has evolved over the centuries and is now in a modern urban context.

Conscious procreation: neo-malthusianism in southern Europe and Latin America in around 1900

One main concern of Ecological Economics is the balance between human population and natural resources. This is rightly named the Malthusian question because Malthus predicted that human populations, if unchecked, would grow exponentially while agricultural production (and other land-based productions) would be subject to decreasing returns to the labour input. This article shows that over one hundred years ago, there was in Europe and America a successful social movement that called itself Neo-Malthusianism. In contrast to Malthus’ pessimism, it believed that population growth could be stopped among the poor classes by voluntary decisions. Women were entitled to choose the number of children they wanted to have. The movement did not appeal to the State to impose restrictions on population growth. On the contrary, in Southern Europe it was based on "bottom up" activism against governments and the Catholic Church.

The relevance of post-match LTC: why has the Spanish labor market become as volatile as the US one?

We present a Search and Matching model with heterogeneous workers (entrants and incumbents) that replicates the stylized facts characterizing the US and the Spanish labor markets. Under this benchmark, we find the Post-Match Labor Turnover Costs (PMLTC) to be the centerpiece to explain why the Spanish labor market is as volatile as the US one. The two driving forces governing this volatility are the gaps between entrants and incumbents in terms of separation costs and productivity. We use the model to analyze the cyclical implications of changes in labor market institutions affecting these two gaps. The scenario with a low degree of workers’ heterogeneity illustrates its suitability to understand why the Spanish labor market has become as volatile as the US one.

Efectes de la post-descàrrega del plasma en teixits de llana i poliamida6

Els teixits de llana presenten l’inconvenient de feltrar (encongir) degut a la presència d’escates i a les característiques hidrofòbiques de la seva superfície. Els tractaments amb plasma (gas ionitzat) són una alternativa ecològica als tractaments tradicionals d’anti feltratge de la llana. També són una innovació en el camp de les fibres sintètiques ja que incrementen la hidrofìlia i/o la rugositat. Malgrat les seves avantatges, l’elevat cost de la maquinària de plasma de baixa temperatura existent per a la indústria tèxtil ha frenat la seva aplicació. Basant-se en estudis preliminars, s’ha avaluat l’efecte de la post-descàrrega del plasma sobre l’encongiment dels teixits de llana, així com els seus efectes en la modificació de la morfologia superficial de llana i poliamida 6.
