- Collecting and preserving media art in Portuguese museumsPublication . Direito, Eva; Sá, Cristina; Teixeira, JoanaThis research aims to map the practices surrounding the collection of media art in Portuguese museums, with a particular focus on the preservation strategies employed by relevant institutions. At the core of the study is a critical analysis of data gathered through an online survey, completed by the following institutions: Museu da Bienal de Cerveira, Museu de Arte Contemporânea de Ser-ralves, Centro de Arte Oliva, Coleção de Arte Contemporânea do Estado, and Museu Nacional de Arte Contemporânea do Chiado.The findings indicate a significant shortage of specialized conservators in Portugal, along with a lack of standardized terminology in the preservation of media art. The brevity of the sample suggests a lack of transparency from the institutions and limited public access to digital documentation con-cerning our object of study. Nonetheless, this sample provides valuable insight into current practises that typically remain inaccessible to the public.
- 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.
- Development of cement industry, technology, and artistic applications: a historical overview of the Portuguese case within an international contextPublication . Gueidão, Marta; Bordalo, Rui; Nunes, Sandra; Vieira, EduardaThe development of the cement industry and technology was a significant driver of progress in construction and artistic applications. Between the late 19th and 20th centuries, cement-based mortars and concrete were widely used in both utilitarian and artistic heritage, serving as structural materials and decorative ornaments. This paper presents a historical overview of the Portuguese cement industry within an international framework. It traces the evolution of modern hydraulic binders from the 18th-century experiments with clay-rich limestone and pozzolan to the 19th-century development of artificial hydraulic lime and major improvements in production processes, kiln design, and chemical analyses, resulting in the standardization of modern artificial Portland cement. These advancements shaped the adaptation and industrialization of cement in Portugal, and marked a gradual transition from natural to artificial cement around the turn of the century. Cement binders imported from England and France continued to dominate the Portuguese market well into the 20th century, even after national production began in the second half of the 19th century. While current research on modern cement heritage often focuses on built structures, this study highlights the cultural significance of cementitious public art. It explores the transition from functional to artistic uses of cement, particularly during the 19th and 20th centuries, through selected case studies that reflect the different techniques and mortar formulations, as well as international influences on Portuguese cementitious heritage. An early example is the Teatro Nacional de São João, where ornaments created with cement-based mortars reinforced with steel bars and metal mesh reflect the influence of French engineering and the pioneering work of Joseph Monier. By contextualizing the Portuguese case within broader technological and artistic trends, this study contributes to a deeper understanding of cementitious heritage and emphasizes the need for further research on Portuguese cement-based artworks from the 20th century. The findings reveal compositional variations and applications that often relied on evolving techniques and experimental mortar formulations. Thus, understanding the material and technical evolution of cement-based mortars, as well as the cross-cultural exchanges that have shaped their use, is essential for the effective preservation and appreciation of this understudied part of modern heritage.

- 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.

- Pedagogias do cinemático: transdução e exercício antropotécnicoPublication . Natálio, CarlosA longevidade do cinemático e o ocaso mediático do cinema enquanto popular medium industrial traz consigo um problema de transmissão e evolução técnica. Neste ensaio, a partir da lógica ontogénica do movimento cinemático, e da ambiguidade que remete para uma lógica de composição e articulação entre pólos — que Jacques Derrida define como central à noção de phármakon presente em Platão — procuramos refletir acerca da possibilidade de unir em composição e articulação os tradicionais dois eixos da consideração do cinemático, de acordo com as teses do que seria um cinema do objeto e sua evolução técnica, e um cinema do sujeito e particular atenção dada à relação entre o modo de funcionamento do cinema e do humano. O que se propõe é que essa articulação possa ser feita a partir de duas noções de movimento e ressonância: o conceito de transdução e a ideia de exercício antropotécnico. Estas seriam ponto de partida para uma dupla pedagogia sobre o cinemático, que se deposita sobre a herança do cinema.
- Entre a tradição e a modernidade: os pigmentos ao dispor dos artistas e o conhecimento sobre esses materiais em Portugal no início do século XXPublication . Cruz, António JoãoSob a forma de dicionário, são apresentados uns apontamentos manuscritos elaborados provavelmente na década de 1920 sobre a composição dos pigmentos utilizados em pintura e equivalências entre os respectivos nomes. O seu autor, não identificado, tinha experiência de preparação de pigmentos e significativos conhecimentos de química. O dicionário, com cerca de 150 entradas, pretende constituir um instrumento de trabalho útil para a interpretação das referências a pigmentos em fontes documentais da época. Além disso, permite saber quais os pigmentos com que poderá lidar uma intervenção de conservação e restauro de pintura do início do século XX.
