- Current challenges for african cultural heritage: a case study of Guinea-BissauPublication . Temudo, AnaThe restitution of cultural heritage to countries of origin has occupied the recent international political agenda. This article analyses the different perspectives from which this question has been approached, in Portugal and abroad, namely in the legislative field governing heritage institutions, in the academic field and in the public sphere. This analysis aims to understand the current meanings attributed to African heritage in museums and other Western heritage institutions, as well as in the countries of origin. As a case study it presents the heritage reality of Guinea-Bissau and indicates different possibilities for a fair representation of today’s diasporic communities, aiming to contribute to an informed debate on the impact of the return and relocation of African heritage to their countries of origin on future representations of African culture and identity on a global scale.
- From conservation to archaeological sites a survey of the conservator-restorer practice in safeguarding of Portuguese Luso-Roman archaeological ruins in 20th centuryPublication . Pinto, Mariana Durana; d’Encarnação, José; Vieira, EduardaThe fascination with the past remains began already many centuries ago, and became an intrinsic characteristic of Western peoples, and it was under this framework that Archaeology arose as a science, based on the need for the study and preservation of the traces found. Portugal was no exception, and along with the consolidation and evolution of Archaeology as a scienti c and professional area, concerns associated with the preservation, safeguarding, and museumization of archaeological heritage appeared because of the archaeological campaigns themselves. It was in this context that the gure of the conservator-restorer gradually emerged, whose evolution, applied to archaeological goods, accompanied the development of this scienti c area, especially after April 25, 1974.
- Image, ritual and urban form: Porto in the 16th CenturyPublication . Afonso, José FerrãoIn the early 17th Century, the Spanish painter Francisco Pacheco railed against his apprentices, telling them that the image should stand out of the picture. The topic was the one most debated in the art of the Counter-Reformation, whose main directives, outlined in the Council of Trent, would be put in motion simultaneously with urban "Christianisation". They presupposed a social contract, established between producer and receiver, implying maximum clarity of the message, which involved an ambiguous grey area that would be reserved for the outside of the focus. In painting, which sacrificed everything that was incidental or extraneous to the story, showing the essential and neglecting the accessory, the binary radicalism of the concept became more explicit, through the Caravaggian illumination or in the case above, the Spanish tenebrism of Velásquez, to whom Pacheco's admonition was addressed. In our Doctoral Thesis presented at the School of Architecture in Barcelona, we sought to demonstrate that the Plastic Arts were not the only field for the application of Luminist principles. In this article we aim to summarise this thesis by exposing the important relationships between image, ritual and urban form in 16th Century Porto, after a time, therefore, the late Middle Ages, which Huizinga classified as deeply iconophile , in which image and ritual were put at the service of the reformulation of a State becoming increasingly centralised and interventionist, whose action extended to the sphere of the Church: with King João II, and especially King Manuel I, the Crown was an active sponsor of religious reform that was pursued with redoubled energy and systematisation, from the reign of "the Pious", then already within the political system of close bilateral cooperation that was designated the Confessional State. We therefore believe that this type of approach to anthropological and symbolic components, which seeks to take into account the increasing importance that is given in contemporary research on the city's history, can be very fruitful.
- Mass tourism, cultural heritage, and traditional values within citizen lifestyle in Porto (Portugal): an overview through the HAC4CG projectPublication . Vieira, Eduarda; Pelaez, Ana; Rosa, Inês; Lemos, Teresa; Bordalo, Rui; Vasconcelos, Marta; Moreira, PatríciaPorto has a rich urban mesh and unique cultural identity, whose preservation has been the basis of its historic centre classification as a World Heritage Site by UNESCO (1996). The increase in demand of Porto as a tourism destination since 2015 was simultaneously favoured by the opening of Porto’s airport new terminal that greatly powered low-cost companies and the licensing for the rehabilitation of houses for hostels and restaurants. These were factors of opportunity that allowed an exponential growth of tourism and a for-profit rehabilitation process in the entire city without proper control. Beyond the impact on housing and gentrification, mass tourism has had a great impact on the city’s lifestyle. The local community is currently confronted with these rapid metamorphoses, becoming the agent of a process of acculturation that is complex and unsustainable in the long run and with implications in the construction of Identity and future Collective Memory. Furthermore, to attract the newly arrived costumers and their diverse culinary preferences, the traditional local gastronomy has been changed, remodelled, and repackaged. Deep changes were observed either in traditional food consumption value chains as well in the grocery’s stores, markets, and restaurants. This communication aims to highlight the preliminary results of the research conducted under the HAC4GC project.
- Modelling an XRF method for determining gilding thickness in silver cultural heritage objects without sample collection: case studies on 16th century Portuguese silverwarePublication . Lopes Cordeiro, Catarina; Bottaini, Carlo; Bordalo, Rui; Sousa, Gonçalo Vasconcelos e; Pessanha, SofiaIn situ X-ray fluorescence is a non-invasive technique that is widely used in historical objects, namely in pieces of gilded silver, to determine the composition of the alloy and gilding. In the case of gilded silver, fire gilding was a mercury-based historical technique that is no longer practiced. Moreover, with traditional XRF analysis is possible to determine the thickness of the gilding by using given intensity ratios of the characteristic lines of silver. However, this requires the analysis of the substrate, for the calculation of the intensity ratio without gilding, which is not always accessible. This study presents and validates a methodology for the calculation of the thickness of fire gilding silver pieces using XRF analysis with a commercial spectrometer and without the need to analyse the isolated substrate. Six silver alloy mock-up samples were produced following historical techniques and generic intensity ratio for K? and K? lines of silver in the alloy was calculated (6.35 ± 0.05), to be used in any alloy with a silver composition over 75 %. Since attenuation of the silver's characteristic lines depends on the gilding composition, different Hg concentrations (5 %–20 %) were tested. The results obtained with this approach for the mock-ups was compared with SEM-EDS measurements for gauging uncertainty and the methodology was then applied to three pieces of 16th century Portuguese silverware. This adaptation of previously established principles, proved to be effective to calculate the thickness of fire gilding on silver and was validated to be applied, in situ, in real museum artworks without the need for sample collection.
- Residências VERTIGO STARTS: o papel da arte na inovação industrialPublication . Teixeira, Luís Miguel; Oliveira, Carla EsmeraldoEste artigo tem como principal objetivo discutir o papel da arte, particularmente através das VERTIGO-STARTS Residencies, na promoção da inovação em contextos industriais. A crescente convergência entre arte, ciência e tecnologia está a transformar a forma como a inovação é concebida e implementada. Neste cenário, as residências artísticas do programa VERTIGO-STARTS demonstram o poder da integração de artistas em ambientes industriais e tecnológicos, criando um terreno fértil para a geração de novas ideias e soluções criativas. O estudo ICT ART CONNECT – “Activities Linking ICT and ART: Past experiences – Future activities” destacou a necessidade de sinergias mais profundas entre arte e tecnologia como catalisadores de inovação, o que levou à criação da Iniciativa STARTS pela Comissão Europeia em 2012. Este programa foi concebido para fortalecer essa colaboração interdisciplinar, incentivando o desenvolvimento de soluções criativas para problemas tecnológicos complexos. Dentro desse contexto, o Programa VERTIGO destaca-se como um componente essencial da Iniciativa STARTS, com ênfase nas residências artísticas STARTS. Estas residências foram concebidas para integrar artistas em ambientes tecnológicos e industriais, com o objetivo de estimular a criatividade e a inovação. Através do mapeamento de 45 residências coordenadas pelo programa VERTIGO, o artigo caracteriza as residências, a metodologia adotada, as estratégias de disseminação e os resultados alcançados. A metodologia utilizada nas residências seguiu uma abordagem colaborativa estruturada, que incluiu workshops de cocriação, sessões de brainstorming e prototipagem rápida. Artistas e profissionais de tecnologia trabalharam em conjunto para explorar novas ideias e desenvolver soluções inovadoras. A avaliação do sucesso dessas colaborações foi baseada em métricas como a inovação gerada, a integração de novas tecnologias e o impacto nas práticas industriais dos parceiros envolvidos. Entre os resultados mais notáveis das STARTS Residencies, destaca-se o projeto, AIBO, da artista Ellen Pearlman, que aplicou princípios artísticos à inteligência artificial para desenvolver uma nova interface de comunicação. Outro exemplo inclui a colaboração no setor de biotecnologia, onde artistas ajudaram a repensar processos de visualização de dados biológicos, resultando em novas ferramentas de análise. Estes exemplos sublinham o impacto concreto das residências na criação de soluções disruptivas e aplicáveis a diversos setores industriais. A disseminação dos resultados das residências é igualmente essencial para maximizar o seu impacto. Através de conferências, publicações e redes de inovação, as inovações desenvolvidas foram amplamente divulgadas, permitindo que práticas inovadoras fossem aplicadas diretamente em contextos industriais. A adoção de robôs inteligentes pela indústria multinacional de elevadores Schindler, desenvolvida durante a residência CYBERSPECIES PROXIMITY, através do projeto Human-Robot Co-Mobility, dos artistas Ana Dumitriu e Alex May é um exemplo claro de como a colaboração interdisciplinar pode ter impactos diretos no setor industrial. O artigo conclui com uma análise do potencial dessas 45 residências artísticas para fomentar a inovação em contextos industriais. A integração de arte, ciência e tecnologia mostrou-se um poderoso motor para a geração de novas ideias e soluções criativas, capazes de transformar processos industriais e tecnológicos. A Iniciativa STARTS representa um modelo promissor para futuras iniciativas que busquem unir arte e tecnologia em prol da inovação. À medida que o mundo enfrenta desafios cada vez mais complexos, é crucial continuar a explorar esses modelos colaborativos, garantindo que a criatividade artística se torne um pilar central nas estratégias de inovação industrial. As VERTIGO-STARTS Residencies, portanto, demonstram como a interdisciplinaridade enriquece o processo criativo e contribui para o desenvolvimento de soluções inovadoras que podem ser aplicadas em diversos setores.
