This catalogue for a show at the Royal Museum of Fine Arts, Brussels, brings Picasso's relationship to abstraction into focus. With more than 120 exceptional works of art in dialogue with some of the great works of the early 20th century abstraction movement, it addresses the major stages that punctuated the links between Picasso's work and the history of abstract art. It covers the period from the first Cubist experiments of 1907, carried out simultaneously with Les Demoiselles d'Avignon, to his later work, which is sometimes situated on the borders of gestural painting.
