Escultura em estuque em Portugal no século XVI
Martins, Joana; Miguel, Catarina; Rodrigues, Paulo Simões; Carvalho, Maria João VilhenaA arte do estuque, amplamente utilizada para decoração arquitetónica no século XVI, permanece um campo pouco explorado na historiografia da arte portuguesa. O presente estudo aborda esta lacuna, focando na análise dos relevos em estuque policromado do Museu Nacional de Arte Antiga (MNAA), através de uma análise interdisciplinar. O objetivo principal é oferecer uma visão integrada e detalhada sobre a produção de...
Cistercian Horizons - collected essays
Miguel, Catarina; Bottura-Scardina, SilviaMediaeval blue colour has long been the subject of several histories and stories concerning its meanings and sources, especially the use of ultramarine and the introduction/transition to azurite in the art history painting’s production. Being the most expensive blue pigment during the mediaeval to renascence period, ultramarine is said to have been selectively used for the most important representations of the ...

Algaff, Shatila; Bottura-Scardina, Silvia; Fernandes-Barreira, Catarina; Miguel, CatarinaMedieval illuminated manuscripts are among the best testimonies of the life of medieval scriptoria. This work traces the biographical trajectory of a Lectionary according to the Cistercian rite – the Alc. 433 - through the liturgical studies and the material characterisation of its painted illuminations, with the aim of obtaining the chronological timeline of the use of colour materials in the Portuguese script...
“On the use of in-situ spectroscopic techniques for the study of the provenance...
Parungao, Dorothy; Candeias, Antonio; Lopes, J.A.; Miguel, CatarinaIvory trafficking is a multifaceted problem that has long endangered the fate of African and Asian ele- phants. In field investigations, it is essential to conduct ivory inspections in a nondestructive manner to prevent the inclusion of noncompliant materials. In this research, a practical approach to identify Asian and African elephants’ ivories was developed using an integrated methodology of art history, vibra...

Valadas, Sara; Reis, Teresa; Miguel, CatarinaExistem muitas histórias por contar, muitas das quais poderiam ter ficado perdidas no esquecimento se não fossem os avanços da ciência e da tecnologia aplicada ao estudo do Património. O que escondem os retratos dos Vice-Reis e Governadores da Índia? Como é que a ciência pode contribuir para a autenticação de selos postais? E como pode também contribuir para um novo olhar sobre a evolução da utilização de mater...

Comparative assessment of two portable Raman spectrometers for the characterisa...
Bottura-Scardina, Silvia; Vandenabeele, Peter; Miguel, Catarina; Candeias, AntónioThis paper explores the use of portable Raman instruments to characterise nat- ural dye lakes in paint mixtures, as an alternative approach to other Raman techniques (e.g. SERS). Raman spectroscopy has indeed been used extensively to study natural dyes as pure substances or as artistic pigments (dye lakes). However, the examination of these compounds with Raman spectroscopy is particularly challenging because o...
