A coordenadora do Grupo de investigação Cultura, Mediação e Artes participa no Congress 2019 of the Humanities and Social Sciences, Annual Conference of the Canadian Society for the History and Philosophy of Science, com a comunicação ”Framing territories, making borders: Photography in the context of the Portuguese Missions of Border Delimitation (1890-1931)“. O evento decorre de 1 a 3 de junho, na British Columbia University, em Vancouver, no Canadá.
Photogrammetry enabled the emergence of precision cartography and a considerable number of the photographs produced by the Missions for Border Delimitation make part of photogrammetry’s history. Photographic cameras and images were used as metric devices of territories. We are referring to eight missions of border delimitation in Angola and Mozambique, between 1890 and 1931, commanded by the Cartography Commission, an institution of the Ministry of the Foreign Affairs and Overseas. All documentation, including photographic albums, negatives and some prints, are now at the Overseas Historical Archive. Besides the photogrammetric uses, all missions have photographic albums portraying the succession of border signs with their geographical coordinates, certifying through photography their indisputable reality. Complementing the maps, these photos should not be simply viewed as documents of the border and an easier way to get immediate information about border coordinates. They are symbolically making the border. In the context of the so called Pacification Wars — wars led by the Portuguese authorities against the Angolan and Mozambican local tribes to occupy the interior areas of the colonies, after the 1885 Berlin Conference that divided Africa between the European colonial countries — these photographs are political gestures, property certificates. Each side of the border produced their own photographic albums. We also found among these, some group photos portraying the mission’s chief personnel in each side of the border. They portray a certain kind of conversation circle without which borders were not built, and that also show conviviality among both factions. The Africans, however, are not in these official photos, nor are they included in these scientific and political conversation circles.
