Born in Chaves in 1920, Nadir Afonso graduated in architecture from the Porto School of Fine Arts and attended the Paris School of Fine Arts in 1946, a city to which he maintained a strong connection for many years and where He had the opportunity to develop his knowledge and contacts, having worked in Corbusier's studio and lived with Vasarely, to whom he was linked by a relationship of friendship and an affinity on an aesthetic level. Definitely opting for painting, Nadir Afonso abandoned architecture in 1965, maintaining, however, many ties with his training as an architect, in the way he privileges urban architecture, within the language of a geometrism that comes to define his style, from the fifties onwards. His painting, which in the forties and fifties involved figuration unfolding into landscapes and nude studies, surrealizing compositions and an almost lyrical landscaping in watercolors, evolved in the 1990s. ;each of fifty for an abstract geometricism, integrating the movement in the 'Espacillimité' series in 1955, and later to the language that best defines the artist's style, a geometricism with figurative references to real or invented urban landscapes. The current exhibition of silkscreen prints precisely documents the evolution underway since the seventies, towards the emphasis on geometry, which for the author reflects the essential order of the universe. This is an exhibition that celebrates the artist's 80th birthday and, at the same time, the twentieth anniversary of the Portuguese Screen Printing Center. Text by Maria João Fernandes
