- Entrevista a Arjun AppaduraiPublication . Ferreira, TeresaAntropólogo cultural, nascido em Mumbai, Índia, Arjun Appadurai é um dos mais relevantes intelectuais públicos da modernidade. Tem dedicado a sua obra a temáticas de interesse tão actual quanto a globalização, o urbanismo, o consumo e a migração, a par da análise aprofundada sobre os media como veículo catalisador de informação identitária e cultural. Conhecido a partir do lançamento de Modernity at Large. Cultural Dimensions of Globalization (1996), a análise do fenómeno da fluidez geográfica (populacional) leva-o a cunhar novos termos que servem a descrição da complexidade das redes culturais. O seu trabalho mais recente, Fear of Small Numbers. An Essay on The Geography of Anger (2006), foca as questões da pobreza e da inclusão social, sobretudo nas grandes cidades, tentando explicar, a partir de um ponto de vista [des]localizado, a natureza do terrorismo e da violência mundial. Desde 2004, é professor de Ciências Sociais na New School University de Nova Iorque, tendo anteriormente desempenhado as funções de professor de Estudos Internacionais (Antropologia, Ciência Política e Sociologia) na Universidade de Yale. Entre 2002 e 2004, distinguiu-se como director do Center for Cities and Globalization na mesma universidade. Além das obras já mencionadas, destacam-se ainda: Feelings Are Always Local (2005), o ensaio «Archive and Aspiration» (2004-05) e Space Identity Uncertainty (2006), também referido na entrevista que abaixo se transcreve, e que resulta do encontro com este comissário da conferência organizada pela Fundação Gulbenkian, em Lisboa, sobre o tema «Podemos Viver sem o Outro? As possibilidades e os limites da interculturalidade», Outubro de 2008.

- Exploring a forgotten heritage: the case study of Saint Vincent Martyr's simulacrumPublication . Palmeirão, Joana; Nunes, Margarida; Manhita, Ana; Curto, Ana; Piorro, Luís; Vieira, Eduarda; Ferreira, TeresaThe simulacrum of Saint Vincent Martyr, one of four corpi santi at the Major Seminary of Coimbra, Portugal, features Roman-origin bones mounted in metallic frameworks and covered with intricate Baroque garments. Enshrined within the urn-altar in Saint Michael's Chapel, its remains were exhumed from the Catacomb of Priscila and brought to Portugal in 1760 by Bishop Count D. Miguel da Anunciação. This study employs a multianalytical approach to examine the simulacrum's materiality, construction, and state of conservation. Non-invasive techniques, including digital radiography and borescope inspection, assessed structural integrity and skeletal arrangement. When feasible, micro-samples were collected for laboratory analysis. Optical microscopy and scanning electron microscopy with chemical analysis were used to analyse paper, textile fibres, and metal threads, revealing evidence of both craftsmanship and deterioration patterns. Additionally, Fourier-transform infrared spectroscopy characterised adhesives, coatings, and pigments, while chromatographic techniques identified dyes in garments and wax components on the face. Results corroborated photochemical damage, textile decay, and structural alterations, with in situ radiographic analyses revealing misaligned skeletal remains. Notably, softwood pulp paper with kaolin and an emerald green pigment in the flower crown points to a 19th-century local intervention after the French invasions of 1810. Furthermore, calcium carbonate in wax and lead-based pigments with iron oxides on the simulacrum's face indicate intentional methods to enhance durability and mimic human features. This study integrates material analysis with historical context to deepen understanding of Saint Vincent's simulacrum, tracing its material transformations and informing future conservation strategies for similar artefacts.

- Material characterization of an 18th-century Roman martyr' reliquary: the case study of Saint Fortunato from Guimarães, PortugalPublication . Palmeirão, Joana; Nunes, Margarida; Manhita, Ana; Coutinho, Maria; Vieira, Eduarda; Ferreira, TeresaThe Roman Catholic Church encouraged the manufacture of life-size reliquaries simulating human bodies to worship and display the bones exhumed from Rome's catacombs (corpi santi) of the allegedly early martyrs of Christianity. Embraced by the Baroque aesthetic, this type of devotional receptacle began to be produced in the late 17th-century and rapidly spread throughout Western Christendom. Portugal was no exception. Between the 18th and the second half of the 19th centuries, dozens of convents, churches, and oratories received the simulated bodies of those saintly heroes. In the last four years, the first author's doctoral research has focused on the historical and scientific study of this typology of reliquaries in Portugal. While establishing a national inventory, the study of historical documentation has shown the Roman origins of the sacred bones, their religious value, and the popular devotions associated with them. As for the scientific research it has highlighted the manufacturing techniques and materials adopted by pious craftsmen. This work aims to present the analytical results on the simulacrum of Saint Fortunato Martyr from Guimarães. This simulacrum was produced during the papacy of Pius VI (1775-1799) as several other simulacra inventoried in Portugal and abroad. A batch of analytical techniques that included Optical Microscopy (OM), Fourier-Transform InfraRed Spectroscopy (FT-IR), High-Performance Liquid Chromatography coupled with Diode Array Detection and Mass Spectrometry (HPLC-DAD-MS), and Scanning Electron Microscopy and X-Rays Microanalysis (SEM/EDX) were utilized for morphological evaluation and chemical compositional analysis of fibres, dyes and metal threads. The results will provide new data for the material characterization of 18th-century life-size Roman martyrs' simulacra.
- Monitorização de gases poluentes em microclimas de museus: estratégia relevante para a conservação preventivaPublication . Barbosa, Karen; Ferreira, Teresa; Moreira, Patrícia; Vieira, EduardaA exposição a uma atmosfera rica em poluentes voláteis pode colocar em risco as coleções de museus, galerias, bibliotecas ou arquivos. Monitorizar poluentes voláteis em museus é ainda hoje uma prática pouco habitual na maioria das instituições. Compostos orgânicos voláteis (COVs) podem ser libertados de diversas fontes, incluindo os materiais que compõem os próprios artefactos. A existência de poluentes em locais fechados, com inadequada renovação de ar, em simultâneo com valores elevados ou oscilações significativas de temperatura e humidade relativa (HR), pode conduzir à degradação acentuada dos materiais mais reativos. A tendência que se observa nos museus para enclausurar os artefactos em vitrinas ou caixas poderá potenciar a formação de microclimas com elevada concentração de COVs. Pretende-se neste trabalho alertar para o risco dos poluentes gasosos em ambiente museológico e traçar recomendações que incentivem as instituições detentoras de património a implementar um plano de monitorização destes poluentes, associado à prevenção de riscos.
- Reconstituição histórica virtual do retábulo-mor da Igreja do Espírito Santo de Évora: aplicação ao Património da infografia web-basedPublication . Pereira, Catarina; Henriques, Frederico; Carriço, Nuno; Amaral, Vanda; Ferreira, Teresa; Candeias, AntónioAs a part of a multidisciplinary and integrated research, including conservation sciences and history, a proposal is presented for the historical reconstitution and the virtual restoration of the mannerist altarpiece of the main altar at the Espírito Santo Church, in Évora. The collected data is abundant and the scientific information, because of its technicality, is less prone to be easily understood by the general public, thus becoming less accessible. Web-based infographics are explored as privileged forms of disseminating results and raising awareness to Cultural Heritage. The project materializes as an Internet platform where data and a reconstitution proposal are shared in a visual and interactive way. In addition to the digital virtual reconstitution (2D), some tridimensional models (3D) are presented of various elements of the altarpiece, obtained using methods of computer graphics and digital photogrammetry.
- The study of two impressive simulacra at Santa Casa da Misericórdia de Almada, PortugalPublication . Ferreira, Teresa; Nunes, Margarida; Curto, Ana; Palmeirão, Joana; Manhita, Ana; Olival, Fernanda; Piorro, Luís; Monteiro, Paula; Vieira, EduardaSimulacra, or full-body reliquaries of corpi santi, have largely been overlooked in the discourse of the past century by the Church, the general public, and scholars. This work investigates two noteworthy cases among simulacra—two young individuals, St. Primogenita and St. Theodore—from Santa Casa da Misericórdia de Almada in Portugal. Based on a historical and analytical approach, the study examines the simulacra context, assembly methods, materials, symbols of martyrdom, and adornments. Their possible arrival in Portugal in the late eighteenth century is supported by the Bishop’s seal and textile features that reflect the fashion of that period. Radiographic imaging and particularly borescope inspections revealed distinct assembly techniques, with St. Theodore displaying meticulous anatomical assembly, while St. Primogenita’s construction is less precise. However, access to the cranium fragments of St. Primogenita revealed an elaborate consolidation method. SEM–EDS, FT-IR, and Py-GC–MS analyses identified a fibrous material coated with a dark brown paste, likely used to bond the unfused parts of the ectocranium fragments of a young individual, as well as a paste applied to reinforce the endocranium. Martyrdom symbols further distinguished the simulacra, with St. Primogenita adorned with a silk petal crown attached using animal glue, whereas St. Theodore’s crown was crafted from pigment-dyed cellulosic materials. LC-DAD-MS analysis revealed the natural dyes used in coloured threads. Only St. Primogenita retained fragments from a phial of blood, where a creative method may have been employed to emphasise the blood content. This investigation highlighted the complexity and artistry behind these simulacra.
