In the history of 20th-century art, Pablo Picasso (1881-1973) stands alone. His enormous output of paintings, drawings, lithographs, ceramics, and sculptures is one of the most diverse and creatively energetic ever produced. A relentless innovator, his aesthetic bravado kept him one step ahead of his contemporaries. With almost 1500 illustrations, this exhaustive study reviews Picasso"s entire oeuvre, from the early Blue and Rose Periods, through the cubist, classicist, and political phases, and finally to the late work of the artist, still vital and productive in his nineties.
