Aurèlia Muñoz (1926–2011) learned macramé from her aunt while convalescing as a child. She spent the rest of her life giving it a voice that was operatic, ritualistic, even supernatural. Vast knotted structures in jute, sisal, cotton, and nylon spill into space. Kite-shaped sculptures seem to float. Installations web rooms like alien life forms. Muñoz was selected for several Lausanne Biennials alongside Sheila Hicks, Magdalena Abakanowicz, and Olga de Amaral—the generation that turned fiber art into sculpture—and yet spent decades classified as a craftsperson. The Museo Reina Sofía is now staging the first major retrospective of her work. —Elena Clavarino
