O presente relatório de estágio aborda o estudo e intervenção de duas cruzes-relicário do Museu
Nacional de Arte Antiga (Lisboa, Portugal), datadas do século XVII. Uma das cruzes com
o número de inventário MNAA inv. 79 OUR é proveniente do Mosteiro da Madre de Deus e
a outra, identificada como MNAA inv. 207 OUR é proveniente do Mosteiro de Santos-o-Novo,
ambos em Lisboa.
Esta tipologia de relicários é bastante comum em Portugal, onde a mesma se destaca pelo seu
trabalho artístico e variedade de técnicas utilizadas, com a finalidade de preservar as relíquias,
exibi-las e glorificá-las. Deste modo, o estudo contemplou o enquadramento histórico das cruzes
e a intervenção de ambas, que foi iniciada por um registo fotográfico e seguinte diagnóstico,
e que passou pela definição de uma metodologia a aplicar na intervenção, com a realização
de exames analíticos, testes de solubilidade e posterior intervenção de conservação e restauro
das peças.
A peça MNAA inv. 79 OUR apresenta-se como sendo constituída por uma liga de Ag-Cu, com
diversas patologias tais como: produtos de corrosão (tarnishing), deformações, elementos em
falta, depósitos de possíveis intervenções anteriores e sujidade/poeiras. A peça MNAA inv.
207 OUR, analisada e interpretada como sendo uma liga de Ag-Cu com um douramento (Au),
apresenta, também, patologias semelhantes, como: tarnishing, elementos em falta, depósitos
de possíveis intervenções anteriores e zonas de iridescências.
Após a execução de vários testes de solubilidade, com base numa revisão de literatura, a peça
MNAA inv. 79 OUR foi intervencionada com recurso ao abrasivo de CaCO3, e a peça MNAA
inv. 207 OUR foi intervencionada com EDTA 4Na, seguido de CaCO3. Ambas as cruzes-relicário
se apresentam como sendo peças compósitas. Para além do metal, contêm, ainda, madeira,
tecido, papel e osso, sendo que a maioria dos materiais foram identificados e intervencionados.
This report is about the study and intervention of two reliquary crosses from the National Museum of Ancient Art (Lisbon, Portugal), being both pieces dated to the 17th century. One of the crosses, identified by its inventory number MNAA inv. 79 OUR, is from the Monastery of Madre de Deus, and the other, identified as MNAA inv. 207 OUR, is from the Monastery of Santos-o-Novo, both located in Lisbon. This type of reliquary is quite common in Portugal and stands out by its artistic work and variety of techniques used to preserve, exhibit, and glorify these relics. As such, this study included the historical context of both crosses, and the intervention, which was initiated with a photographic record, following the diagnosis, with included the definition of a methodology to be applicable in the intervention, with the performance of analytical exams, solubility tests and subsequent conservation and restauration of the pieces. The piece MNAA inv. 79 OUR, was manufactured in an Ag-Cu alloy, with several pathologies such as: corrosion products (tarnishing), deformations, missing elements, deposits from possible previous interventions, and dirt/dust. The piece MNAA inv. 207 OUR, analyzed as being an Ag-Cu alloy with a gilding (Au), also presents similar pathologies, such as: tarnishing, missing elements, deposits from possible previous interventions and some iridescence areas. After performing several solubility tests, and based on a literature review, the piece MNAA inv. 79 OUR was intervened with CaCO3 abrasive, and the piece MNAA inv. 207 OUR, was intervened with EDTA 4Na, followed by CaCO3. Both reliquary crosses are composite pieces. Besides metal, they also contain wood, textile, paper, and bone, having been most of these materials duly identified and subject to conservation treatments.
