Um universo de pedra

Foi há pouco publicado o livro seguinte:

Philip Ball, Universe of Stone. A biography of Chartres Cathedral, New York, Harper Collins, 2008.

Apresentação:

Chartres Cathedral, south of Paris, is revered as one of the most beautiful and profound works of art in the Western canon. But what did it mean to those who constructed it in the twelfth and thirteenth centuries? And why, during this time, did Europeans begin to build churches in a new style, at such immense height and with such glorious play of light, in the soaring manner we now call Gothic?

Universe of Stone shows that the Gothic cathedrals encode a far-reaching shift in the way medieval thinkers perceived their relationship with their world. For the first time, they began to believe in an orderly, rational world that could be investigated and understood. This change marked the beginning of Western science and also the start of a long and, indeed, unfinished struggle to reconcile faith and reason.

By embedding the cathedral in the culture of the twelfth century—its schools of philosophy and science, its trades and technologies, its politics and religious debates—Philip Ball makes sense of the visual and emotional power of Chartres. Beautifully illustrated and written, filled with astonishing insight, Universe of Stone argues that Chartres is a sublime expression of the originality and vitality of a true "first renaissance," one that occurred long before the birth of Leonardo da Vinci, Michelangelo, or Francis Bacon.

A Arte Efémera e a Conservação

Nos dias 6 e 7 de Novembro realiza-se no Museu do Oriente, Lisboa, um encontro sobre A Arte Efémera e a Conservação. O paradigma da arte contemporânea e dos bens etnográficos. A organização é da Fundação Oriente, do Instituto dos Museus e da Conservação, do Museu Colecção Berardo e da Universidade Nova de Lisboa.

Na arte contemporânea a esperança de vida da obra de arte encurta-se radicalmente a partir do início do século XX, com a utilização de materiais de todos os tipos. Os artistas são seduzidos pelas suas capacidades expressivas e potencialidades comunicativas e já não pela sua garantia de durabilidade. Os bens etnográficos, com funções rituais ou simbólicas, colocam o problema desde o início das primeiras colecções. Contudo, em ambos os casos, a fragilidade das obras ou mesmo a sua pretendida efemeridade conflituam com a actual vontade de tudo preservar, característica dos tempos que vivemos. Os problemas práticos e éticos que daí resultam para o museólogo, o conservador-restaurador ou o historiador de arte constituem um enorme manancial de reflexão.

Neste encontro procuraremos reflectir e debater sobre os valores que dificilmente se equilibram na tarefa da preservação, de que são exemplo os valores materiais versus valores conceptuais, rituais ou estéticos. As questões da originalidade e autenticidade em relação com o valor histórico, cultural, a intenção do criador, a intangibilidade, a função social, entre outros. Haverá também espaço para pensar sobre processos alternativos de conservação e o perfil dos profissionais empenhados numa salvaguarda que ultrapassa o domínio da materialidade, que inclui novos meios, implica criatividade e especial atenção não apenas aos objectos, mas também às comunidades e contextos envolvidos.

O restauro do templo romano de Évora

O seguinte artigo está livremente disponível aqui.

António Carlos Silva, "A 'restauração' do templo romano de Évora", A Cidade de Évora, 1, 1994-1995, pp. 63-71.

Resumo:

Este artigo é dedicado ao Templo Romano de Évora, mais precisamente ao seu "restauro" em meados do séc. XIX. O "restauro", incentivado pela intelectualidade eborense, foi informado pelas políticas patrimoniais vigentes na época, que preconizavam a remoção de todos os acrescentos à obra original, e levado acabo por Cinatti.

O autor faz ainda uma pequena resenha histórica acerca da "evolução arquitectónica" e utilização do templo.

Argamassas de revestimento para alvenarias antigas

A seguinte tese está integralmente disponível aqui.

Maria Paulina Santos Forte Faria Rodrigues, Argamassas de revestimento para alvenarias antigas. Contribuição para o estudo da influência dos ligantes, Tese de doutoramento, Lisboa, Universidade Nova de Lisboa, Faculdade de Ciências e Tecnologia, 2004.

Resumo:

O presente trabalho decorre da importância crescente que o conhecimento das argamassas para edifícios antigos tem vindo a assumir. Pretende-se com ele contribuir para o estudo da influência dos ligantes no comportamento das argamassas, em particular no caso da cal aérea e de componentes pozolânicos que com ela possam reagir directamente.

As funções exigidas às argamassas para aplicação em edifícios antigos dependem de várias condicionantes e implicam que estas possuam um conjunto de características nem sempre fáceis de atingir ou compatibilizar. Fundamentalmente estas argamassas têm de proporcionar uma eficiente protecção aos suportes em que são aplicadas, evitando o desenvolvimento de mecanismos que conduzam à sua degradação. Para tal devem registar uma boa compatibilidade mecânica, física e química com os referidos suportes. Simultaneamente, e dentro do possível, devem apresentar características que permitam prevenir a sua própria degradação, incrementando a sua durabilidade face a acções específicas inerentes a edifícios antigos, como seja o ataque por sais solúveis.

A tese foi dividida em duas partes organizadas em oito capítulos. Na primeira parte apresenta-se uma análise bibliográfica genérica sobre argamassas para edifícios antigos, enquanto na segunda parte é registado todo o desenvolvimento experimental desenvolvido.

Para além de serem descritos os procedimentos experimentais utilizados, são comparadas argamassas diversificadas (situadas entre as de cal aérea e as de cimento, bem como argamassas pré-doseadas), argamassas produzidas a partir de diferentes preparações e tipos de cais aéreas e ainda caracterizadas múltiplas argamassas de cal aérea com diferentes componentes pozolânicos, distintas proporções entre a cal e esses componentes e sujeitas a dois tipos de condições de cura.

Apresentam-se ainda uma análise crítica, as conclusões do estudo e propostas para desenvolvimentos futuros do trabalho de investigação realizado.
