By the time she made it, Brazilian artist Lygia Pape’s career had evolved through two schools of geometric abstraction—Concretism and its less rigid Rio de Janeiro counterpart Neo-Concretism. She had made paintings, sculpture, artists’ books, films, installations, and performance art. A retrospective of Pape’s work currently at the Met Breuer—her first solo exhibit in the United States—is highly conceptual, drawing on semiotics, architectural theory, and anthropology, but never losing a deep connection with the visceral realities of daily life.
