La escalera de caracol con ojo a finales del S.XV y comienzos del S.XVI: el caso de la ciudad y tierra de Segovia

Este trabajo de investigación se ha centrado en la escalera de caracol con ojo también denominado caracol de mallorca, en sus primeras apariciones a finales del s.XV y comienzos del s.XVI durante el llamado periodo tardogótico. Este elemento aparentemente sencillo presenta, sin embargo, una gran diversidad de esquemas geométricos. Todavía a día de hoy, no hay explicación del por qué de la mayor difusión de unos con respecto a otros. El objetivo de este trabajo ha sido valorar el papel que el confort/seguridad de uso así como la economía en el trabajo –sencillez de ejecución y coste económico– tuvieron en el contexto de la difusión de este elemento arquitectónico. Este estudio ha analizado en base a estos criterios objetivos, la geometría de cada uno de los esquemas tipo que resuelven la formación del hueco central característico este tipo de escaleras, con la intención de determinar las causas objetivas que pudieron motivar la desigual expansión de los mismos. Una vez determinado el marco teórico, se han establecido dos líneas para abordar el problema. Por un lado se ha planteado el análisis de los modelos teóricos recogidos en los distintos textos de cantería escritos por autores españoles desde finales del s.XVI. Si bien en la época en que se escribieron, la arquitectura gótica como sistema había desaparecido, alguno de sus elementos más característicos, como la escalera de caracol, continuaban empleándose. Las trazas del caracol con ojo recogidas en estos textos, describen habitualmente las soluciones geométricas más frecuentes e incluso los ejemplos construidos más conocidos, los cuales fueron levantados en su mayoría en el período en el cual se desarrolla esta investigación. Por otro lado, este estudio se plantea el análisis de modelos construidos existentes en la Ciudad y Tierra de Segovia. La razón que justifica dichos límites geográficos, la encontramos en que la mayor parte del patrimonio gótico existente en este área fue construido entre finales del s.XV y comienzos del s. XVI. Ambos grupos, modelos teóricos y modelos construidos, recogen la herencia gótica heredada en la construcción de este elemento arquitectónico. Cada una de estas dos líneas establecidas han seguido una metodología específica adaptada al objeto de análisis, si bien ambas se basan en un primer análisis individual y posterior análisis comparativo de los modelos seleccionados. Estos análisis han permitido identificar los distintos esquemas empleados para resolver el hueco central, lo que ha posibilitado establecer una clasificación general de los mismos en tres grupos: caracol con ojo de solución radial, el caracol con ojo de solución no radial y el caracol con ojo de solución tangencial. A partir de los datos y resultados obtenidos del análisis comparativo de los parámetros geométricos que afectan al confort/seguridad de uso y economía en el trabajo de dichos esquemas, podemos concluir que a pesar que los tres esquemas identificados resuelven el caracol con ojo de forma muy similar, el predominio de la solución radial y la caída en el olvido de las soluciones tangencial y no radial estuvieron justificados. ABSTRACT This work focused on the helical staircase, also known as mallorca staircase, in the late 15th and the early 16th centuries. This seemingly simple element, presents however a wide variety of geometrical designs. Still to date, there is no explanation of why some of them were limited use, while others had a wide impact. The aim of this study was to assess the influence which comfort, safety and work economy –ease of construction and financial cost– had on their widespread. This study analysed, following these objective criteria, the geometry of the different designs, which solve the characteristic inner aperture of this type of staircase. And thus, find the reasons, which motivated their uneven spread. Once the theoretical framework was developed, two research lines were set up to address the problem. On one hand, this study analysed the theoretical helical staircases described in the early Spanish texts, which were written since the end of the 16th century. Although these texts were written after the Gothic Architecture system had already disappeared, some of its more representative elements like the helical staircase were still in use. The traces of the helical stair, which are included in these texts, describe the most frequently-used designs and even the most famous real examples which were usually constructed in the Late Gothic period. On the other hand, this study analysed some real helical staircases, which were constructed in the Ciudad y Tierra de Segovia. The reason for choosing these geographical limits is that most of the Gothic buildings of this area were constructed between the end of the 15th and the early 16th centuries, during the Late Gothic period. Both groups, theoretical and constructed samples, collect the Gothic construction tradition of the helical stair. Each of these research lines followed a specific methodology, which was adapted to the research object. Nevertheless, both are based on a first individual analysis of each selected example and a later on comparative one. These analysis allowed the identification of the different layouts which solve the inner aperture of the helical staircase, what made possible to set up a broad classification in three groups, according to the geometrical design strategy that solves the central aperture: the helical staircase by radial solution, the helical staircase by non-radial solution and the helical staircase by tangent solution. The research findings of the comparative analysis of their geometrical parameters, which have an impact in the comfort, safety and work economy, have shown that although all of them solve the helical staircase in a really similar way, the fade into oblivion of the non-radial and tangent approaches was objectively motivated.

Detection of 400-year-old Yersinia pestis DNA in human dental pulp: An approach to the diagnosis of ancient septicemia

Ancient septicemic plague epidemics were reported to have killed millions of people for 2 millenniums. However, confident diagnosis of ancient septicemia solely on the basis of historical clinical observations is not possible. The lack of suitable infected material has prevented direct demonstration of ancient septicemia; thus, the history of most infections such as plague remains hypothetical. The durability of dental pulp, together with its natural sterility, makes it a suitable material on which to base such research. We hypothesized that it would be a lasting refuge for Yersinia pestis, the plague agent. DNA extracts were made from the dental pulp of 12 unerupted teeth extracted from skeletons excavated from 16th and 18th century French graves of persons thought to have died of plague (“plague teeth”) and from 7 ancient negative control teeth. PCRs incorporating ancient DNA extracts and primers specific for the human β-globin gene demonstrated the absence of inhibitors in these preparations. The incorporation of primers specific for Y. pestis rpoB (the RNA polymerase β-subunit-encoding gene) and the recognized virulence-associated pla (the plasminogen activator-encoding gene) repeatedly yielded products that had a nucleotide sequence indistinguishable from that of modern day isolates of the bacterium. The specific pla sequence was obtained from 6 of 12 plague skeleton teeth but 0 of 7 negative controls (P < 0.034, Fisher exact test). A nucleic acid-based confirmation of ancient plague was achieved for historically identified victims, and we have confirmed the presence of the disease at the end of 16th century in France. Dental pulp is an attractive target in the quest to determine the etiology of septicemic illnesses detected in ancient corpses. Molecular techniques could be applied to this material to resolve historical outbreaks.

Estudo semântico-lexical do códice oitocentista Memoria sobre o Plano de Guerra Offensiva e Deffensiva da Capitania de Matto Grosso

Esta tese, com o intuito de contribuir para uma reflexão em torno da história da formação da língua portuguesa no Brasil, propõe como objetivo geral realizar um estudo do léxico no município de Cáceres-MT, tendo como base a discussão sobre manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico de unidades lexicais extraídas de um manuscrito oitocentista. Os objetivos específicos são os seguintes: (i) compreender a história social da Capitania de Mato Grosso e do município de Cáceres, a partir das informações constantes no manuscrito Memoria, e aspectos que envolvam as condições de produção do documento e a biografia do autor; (ii) levantar o léxico do manuscrito, com recorte nos substantivos e adjetivos para servir de base na seleção das unidades lexicais a serem testadas in loco, e investigar a acepção registrada no documento das unidades lexicais, caracterizando, assim, o léxico do período oitocentista; (iii), fazer um cotejo lexicográfico abrangendo dicionários gerais dos séculos XVIII ao XXI; (iv) testar e identificar, a partir do corpus oral constituído por meio de pesquisa de campo na região urbana cacerense, o grau de manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico em relação às unidades lexicais e suas respectivas acepções registradas no manuscrito. Dessa forma, toma-se como corpus de língua escrita de análise o manuscrito oitocentista Memoria sobre o plano de guerra offensiva e deffensiva da Capitania de Matto Grosso e, a partir das unidades lexicais selecionadas e extraídas dele, realizou-se a pesquisa de campo para o recolhimento do corpus de língua oral. Antes dessa recolha, tendo como base teórico-metodológica as disciplinas de Dialetologia e de Geolinguística, selecionou-se a localidade (município de Cáceres - MT) e os informantes (total de dezesseis); elaborou-se o questionário semântico-lexical, considerando fundamentalmente a proposta apresentada pelo Comitê Nacional do Projeto ALiB (2001); e realizou-se a pesquisa de campo e as transcrições das entrevistas. Para análise de natureza semântico-lexical dos corpora, recorreu aos estudos lexicográficos e lexicológicos. Tomando por base os resultados do estudo realizado, constatou-se que na realidade linguística do informante cacerense encontram-se unidades que já integravam o léxico oitocentista da língua portuguesa escrita no Brasil, ou seja, há uma memória semântico-lexical que se mantém no sistema lexical, provavelmente, devido às condições sócioculturais do município de Cáceres, Mato Grosso, cuja população, em grande parte, por quase duzentos anos, viveu na área rural. Todavia, vislumbrou-se um certo equilíbrio entre a manutenção do léxico oitocentista sem deixar de lado a inovação e o mecanismo polissêmico constitutivo do léxico.

"Another Way": The Pneumatology of Deleuzean Minoritarian Communal Interpretation in Scripture, the 16th Century Radical Reformation, and Alternative 21st Century Anabaptist Community

This dissertation proposes a constructive theology of the Holy Spirit called the "pneumatology of minoritarian communal interpretation," the alternative creation of meaning within an oppressive majority context. It illustrates the convergence of Deleuzean philosophy with Anabaptist pneumatology and media communal interpretation theory in three particular locations: 1) selected mentions of the Holy Spirit in the Hebrew Bible and Christian New Testament; 2) the 16th century Radical Reformation; and 3) "Another Way," a 21st century alternative Anabaptist group focused around the spiritual discussion of art and popular media. Chapter One outlines the three theories. Chapter Two examines the Holy Spirit in the Hebrew Bible, particularly 1 Samuel 8, the book of Ezekiel, and the Gospel narratives. Chapter Three examines the pneumatological writings of the Radical Reformers, concentrating particularly on their theologies of the intersection between church and the surrounding majoritarian culture. Chapter Four outlines my original field research with Another Way, and examines the tension between minoritarian communal interpretation and the 21st century semiotic regime. Chapter Five then summarizes the conversations between theory and illustration to propose the pneumatology of minoritarian communal interpretation for Christian theology.

The American portrait tradition : Cephas Thompson 1775-1856

"The purpose of this study is to reveal the work of Cephas Thompson in the context of the American Portrait Tradition as it existed in America from 1775 to 1856. European historic and artistic background serves as the foundation. A critical analysis of the most relevant American portraitists from the seventeenth to the midnineteenth centuries is provided to relate them aesthetically and ideologically with the work of Cephas Thompson and to provide insight into the artistic trends prevalent in Europe and America"

La avenencia: solución pacífica de conflictos en el Derecho de cristianos y musulmanes hispanos (S. X-XVI)

Las fuentes del Derecho español se han ocupado a lo largo del tiempo, y sin solución de continuidad, de la institución del arbitraje en el marco de la administración de justicia. El arbitraje, avenencia o conciliación son términos que poseen un significado singular en los sistemas u ordenamientos jurídicos que han connotado la Historia del Derecho. El Derecho andalusí se ocupó de la institución del arbitraje por dos razones fundamentales. La primera razón de este interés obedecía a su importancia como medio eficaz y rápido para solventar diferencias o conflictos entre partes. La segunda razón se debía a las particularidades que esta modalidad de resolución presentó respecto a la ortodoxia malekí. Este trabajo analiza los elementos y características del arbitraje y la avenencia con el fin de trazar una visión más completa de la institución, que desde la Edad Media fue medio habitual para la solución de situaciones controvertidas entre cristianos y musulmanes.

Avisos, anuncios, reclamos y publicidad en España: siglos XVIII y XIX

Este artículo analiza diversas manifestaciones publicitarias aparecidas en la prensa española de los siglos XVIII y XIX. Considerando que la publicidad moderna nace en los países primero industrializados en torno a esas fechas, esta investigación se ha planteado la hipótesis de que en España, aun con retraso, se inició un proceso similar. Para la recopilación y selección de hechos, hemos utilizado las colecciones digitalizadas de portales que recientemente ofrecen el acceso libre a sus fondos; en particular, los de la Biblioteca Nacional de España, el Archivo de Revistas Catalanas Antiguas y la Hemeroteca Municipal de Madrid.

The episcopal complex of Eio-El Tolmo de Minateda (Hellín, Albacete, Spain). Architecture and spatial organization. 7th to 8th centuries AD

The episcopal complex of Eio, located in El Tolmo de Minateda, was built between the end of the 6th century and the beginning of the 7th century, possibly as a political decision taken by the ecclesiastical authority in the capital of the Visigothic kingdom (Toletum). With the comprehensive study of the whole complex presented below (construction cycles, furniture, decoration and location of spaces), we can interpret the function of each space in the basilica and the domus episcopi, the liturgical and general movement routes, the existence of some hierarchical environments, and specify the chronological development of the buildings. After the Arab-Berber conquest of Hispania in the early 8th century, the whole complex will experience a series of transformations that will convert the religious and monumental public area into a private, residential and industrial Islamic quarter.

The business of fashion in the nineteenth and twentieth centuries

Fashion is a complex social and cultural phenomenon with strong economic implications. Historical analysis reveals that the mechanisms of creating and spreading fashion have not remained constant, but have varied according to social structures, forms of producing and distributing apparel and social media, while the level of influence of fashion on society has increased in line with economic development. This special issue of Investigaciones de Historia Económica-Economic History Research is dedicated to fashion as an economic phenomenon in the contemporary period. The four articles which make it up show the plurality of the subject areas, sources and methodological approaches in the current research on this topic.

Fortification and Frontier: The Project Drawn up by Juan Martín Zermeño for Puebla de Sanabria in 1766

Following the death of engineer General Jorge Próspero de Verboom in 1744 and after a few years of transition in the management of Spanish fortifications, Juan Martín Zermeño took on the role, initially with a temporary mandate, but then definitively during a second period that ran from 1766 until his death in 1772. He began this second period with a certain amount of concern because of what had taken place during the last period of conflict. The Seven Years War (1756–1763) which had brought Spain into conflict with Portugal and England in the Caribbean had also lead to conflict episodes along the Spanish–Portuguese border. Zermeño’s efforts as a planner and general engineer gave priority to the northern part of the Spanish–Portuguese border. After studying the territory and the existing fortifications on both sides of the border, Zermeño drew up three important projects in 1766. The outposts that needed to be reinforced were located, from north to south, at Puebla de Sanabria, Zamora and Ciudad Rodrigo, which is where he is believed to have come from. This latter township already had a modern installation built immediately after the war of the Spanish Succession and reinforced with the Fort of La Concepción. However, Zamora and Puebla de Sanabria had some obsolete fortifications that needed modernising. Since the middle of the 15th century Puebla de Sanabria had had a modern castle with rounded turrets, that of the counts of benavente. During the 16th and 17th centuries it had also been equipped with a walled enclosure with small bastions. During the war of the Spanish Succession the Portuguese had enlarged the enclosure and had erected a tentative offshoot to the west. In order to draw up the ambitious Puebla de Sanabria project Zermeño had the aid of some previous reports and projects, such as those by the count of robelin in 1722, the one by Antonio de Gaver in 1752, and Pedro Moreau’s report dated June 1755. This study includes a technical analysis of Zermeño’s project and its strategic position within the system of fortifications along the Spanish–Portuguese border.

Tiburzio Spannocchi’s project for the fortifications of Fuenterrabía in 1580

Fuenterrabía (Hondarribia) is a town located on the Franco-Spanish border. Between the 16th and 19th centuries it was considered to be one of the most outstanding strongholds in the Basque Country due to its strategic position. The bastion system of fortification was extremely prevalent in this stronghold. It was one of the first Spanish towns to adopt the incipient Renaissance designs of the bastion. The military engineers subsequently carried out continuous fortification projects that enabled the structure to withstand the advances being made in artillery and siege tactics. After the construction of the citadel of Pamplona had begun in 1571, following the design of the prestigious military engineer, Jacobo Palear Fratín and being revised by Viceroy Vespasiano Gonzaga, the aforementioned engineer undertook an ambitious project commissioned by Felipe II to modernise the fortifications of Fuenterrabía. Neither the plans nor the report of this project have been conserved, but in the year 2000, César Fernández Antuña published the report written by Spannocchi on the state of the fortifications of Fuenterrabía when he arrived to the Spanish peninsula, discovered in the Archivo Histórico Provincial de Zaragoza. This document conducts an in-depth analysis of Spannocchi’s project and how it was related to Fratín’s previous project. It concludes that this project encountered problems in updating the new bastions at the end of the 16th century, and identifies the factors which prevented the stronghold from being extended as was the case in Pamplona after Fratín’s project.
