From 1965 onwards, the artistic practice of architect and artist Artur Rosa was defined by geometric abstraction and an exploration of the aesthetics of optical effect. Based on the decomposition of movement through the use of painting and collage, this untitled work is structured by geometric shapes that move within the field of the painting, creating dynamic compositional grids and luminous folds, as well as a game of balance between fullness and the void, interior and exterior, colour and deletion.
