Metodologia para o mapeamento de fenómenos de biodeterioração por manchas negras na pintura mural do séculos XV e XVI com o apoio de processos fotogramétricos e sistemas de registo vetorial

: o caso de estudo da Igreja Paroquial de Santa Marinha, Vila Marim (Vila Real)

Abstract

This dissertation focuses on the architectural surveying combined with photogrammetry of the Vila Marim parish church, located in Vila Real district, in the Northern part of Portugal, whose mural paintings dating from the 15th 16th present an alteration process of black stains, of possible biological origin. This study aims to obtain a more effective tool towards the understanding of the black stains phenomena, which occurs in other mural paintings of the region. The technique of photogrammetry and the architectural survey aren’t new applied to cultural heritage study. Although, combined intend to support an integrated reading of the black stains problem and being a contribution, to a new approach to the comprehension of the biodeterioration on mural painting by black stains through the integration of multiple variables. Thus, we aim to gather different issues that can be or cannot be related with the black stains occurrence, such as materials used in the building construction, building typology, the action of the atmospheric agents, previous reforms and restorations that could have been contributed to change the hygrothermal inertia of the building. Besides we hope to obtain a conservation management tool to the future. This dissertation presents an initial part of architectural survey and the anomaly mappings, using photogrammetry and vectorial register of the church of Santa Marinha located in Vila Marim, in Vila Real district. The theoretical and methodological basis used in this dissertation consists of the compilation of several previous studies such as an article on the history of Building and Builders of the Alcobaça Monastery (Melo&Ribeiro: 2011) and the data gathered in Alexandra Marco's masters dissertation (2016), dedicated to the theme of biodeterioration in mural painting in northern Portugal. Through the architectural survey of the interior and exterior of the building, the state of conservation data was updated, and several maps of the damages were created both for the building and for the murals, to help with the characterization of the state of conservation and to use as a tool to plan the emerging needs for local conservation.
