How my Brazilian library feeds on fragments of a concrete reality refers to the skyscrapers of Rio de Janeiro. It represents an important political and expansionist period in Brazil. The rise of modern architecture gave rise to a new form of cultural expression that overlapped with indigenous architecture.
