No concelho de Tarouca situam-se dos mais significativos monumentos portugueses, comum representativo espólio de pintura portuguesa dos séculos XV e XVI. Entre os vários espécimes encontra-se o da igreja de São Pedro de Tarouca, que integra uma pintura mural, com o tema da “Ressurreição”, situada no arcossólio da nave da Igreja. Trata-se de uma pintura que se destaca pela sua singularidade, existindo poucos exemplares desta época nesta região do país. A pintura, pela sua raridade, foi objecto de estudo e análise laboratorial aquando da intervenção de conservação e restauro, que deixou a descoberto uma obra de carácter marcadamente maneirista, que se encontrava totalmente repintada. Neste sentido, discute-se o contexto cronológico e estilístico da obra, apresenta-se o estudo dos pigmentos utilizados e descreve-se a metodologia de interv...
Along the 16th century altar pieces and wooden structures arose at churches in Foz do Douro, S. Torcato and Amarante. There structures were often substituted, transformed or simply destroyed.
The paper proposes a novel, integrated approach to the identification and quantification of the organic binders, mainly proteinaceous, as the “invisible” component of polychrome layers in artifacts belonging to movable and immovable cultural heritage. The analytical methodology discussed here will demonstrate the significance and efficiency of biochemical assays for the detection of organic binders and how these tests can improve/complement the already existing techniques, while considering also the costs and time of analysis that commonly limit their application in the current laboratory practice for artworks diagnosis.
Our visual perception is strongly influenced by the anatomical structure of the eye and bylighting conditions. While looking at the painting, we perceive existing colour attributes,using retinal photoreceptors – cones – that serve our vision at higher luminance levels.Lighting, on the other hand, affects our colour discrimination as well as our perception ofthree dimensions of colour.During the retouching process our visual system can be affected by multiple optical impressionsthat many painting conservators are not fully aware of. Colour distortion phenomena canimpact our observation stealthily, while producing simultaneous contrasts and afterimagesthat interfere with our colour discrimination as well as our decisions in pigment mixing.The aim of this paper is to analyse these optical properties and to provide practical guidelinesthat...
The displacement of the Royal Portuguese family to Brazil in 1808 became a significant event responsible for a deep change in the Portuguese colony way of living. The vessel Galeota Real, property of King D. João VI of Portugal, also known as Galeota Imperial, was a gift to the King just to be used exclusively on royal ceremonies. An intervention of conservation and restoration of all its elements in gilded carved wood was carried out. This work aimed to return the unity and the magnificence already lost, as a result of time passage and previous restorations. The intervention made possible the acquisition of relevant knowledge on original and historical manufacturing artistic techniques.
In this paper some notes are presented in a dictionary format about composition of pigments applied in painting and their actual equivalence. These manuscripts were probably written in the 1920’s and their non-identified author had considerable experience in pigments’ preparation and also solid chemistry knowledge. The dictionary presents 150 entries and aims to become a useful tool for the interpretation of pigments references in documental sources from this time. Besides it allows identifying the pigments a conservator-restorer may find while performing a conservation intervention on an early 20th century painting.
This study’s goal is to deepen the knowledge about techniques and materials applied in the execution of Portuguese wooden paintings. The Portuguese Catholic University of Oporto gathered a multidisciplinary team in order to study the Pentecost panel from Vasco Fernandes. This study was held in situ, in Santa Cruz de Coimbra Monastery and several techniques of analyses were applied: photographic examination under visible light, infra-red and ultra-violet photography, EDXRF and radiography. This last one allowed us to identify new information regarding both pictorial layer and wooden support, being the support our main concern. The relevance of the study of wooden Portuguese paintings is understandable due to the considerable knowledge gaps that still exist in this field.
