Pablo Picasso’s etching demonstrates the artist’s commitment to new visual forms and techniques. Between 1911 and 1912, in collaboration with Georges Braque, Picasso revolutionized the rendition of pictorial space. Describing the achievement of Cubism, the contemporary poet and critic Guillaume Apollinaire opined that the new pictorial strategy revealed previously undocumented aspects of reality and experience, writing: “The fourth dimension would spring from three known dimensions: it represents the immensity of space eternalizing itself in all directions at any given moment. It is space itself.” The reproductive medium of etching, which permitted Picasso to play with mark-making, testifies to the artist’s energetic spirit of innovation. Through his ongoing experimentation, Picasso contributed to the evolution of new ways of seeing and understanding, characteristic of the technological and social transformations of the new century.
