"Armao de Linhas que se encontram" (Framework of Lines That Meet) is a geometric abstract work by Brazilian artist Almir da Silva Mavignier that exemplifies the concrete art movement's emphasis on pure form and mathematical precision. The composition features intersecting linear elements arranged in a structured spatial configuration, demonstrating Mavignier's engagement with optical relationships and the interplay between positive and negative space. Created during the mid 20th century, the work reflects the artist's training at the Hochschule für Gestaltung in Ulm and his commitment to systematic, non representational visual language.
