Blue nude by Pablo Ruiz Picasso

Picasso appears as the main representative of cubism with Georges Braque. This movement raises a controversy by developing a new way of painting, by breaking down forms and multiplying the points of view that appear simultaneously on the same work. Indeed, if artists like Albert Gleizes and Jean Metzinger developed a real theory of cubism, Picasso and Braque remained attached to technical novelty rather than theory.
