Presenting new scholarship, this publication is an innovative technical study of the Concrete art movement in Argentina, Brazil, and Uruguay from the 1940s to the 1960s.;;Purity Is a Myth presents new scholarship on Concrete art in Argentina, Brazil, and Uruguay from the 1940s to the 1960s. Originally coined by the Dutch artist Theo van Doesburg in 1930, the term concrete denotes abstract painting with no reference to external reality. Van Doesburg argued that there was nothing more real than a line, color, or plane. Artists such as Willys de Castro, Lygia Clark, Waldemar Cordeiro, Hermelindo Fiaminghi, Judith Lauand, Raúl Lozza, Tomás Maldonado, Hélio Oiticica, and Rhod Rothfuss would reinvent this concept in postwar Latin America.;;Drawing on research conducted by Getty and international partners, the essays in this volume address a variety of topics, including the general history, emergence, and reception of Concrete art; processes and color; scientific analysis of works; illustrated chronologies of the paint industry in Brazil and Argentina; and Concrete design on paper. An innovative technical study of the Concrete art movement in Latin America, this volume will be indispensable to scholars, practitioners, and students of Latin American art.
