Lygia Clark is primarily remembered for her participation in the Constructivist movement (leading abstract artist at the forefront of the Neo-Concretist movement in Brazil), her innovative approach to modular sculpture and the participatory art that made her a singularly pioneering force in the world of international art. This volume explores her production in the first decade of her career. Clark devoted her time to painting, constantly experimenting and testing new techniques, becoming an important avant-garde figure in Brazil. Her work in these early years oscillated between figuration and abstraction, creating geometric, system- based paintings which will articulate the visual language of her innovative career.
