The article investigates the many ways in which the grid is exploited in contemporary art. Textile weave, graphic grid, material support, typological system, spatiotemporal framework, computer matrix, narrative and documentary device… the grid emerges as a complex, ambiguous structure evocative of the rational order of science, while simultaneously unlocking hitherto untapped avenues for imagination, intuition and creativity. This book features artworks by artists from Concrete Art, Minimalism, Optical Art, Conceptual Art, Narrative Art, Performance Art, and Digital Art, with a special focus on Brazilian contemporary art
