In 1907 Picasso painted Les Demoiselles d’Avignon (Mus. of Modern Art, New York City), a radical departure from the artistic ideas of the preceding ages and now considered the most significant work in the development toward cubism and modern abstraction (see modern art). The influence of Cézanne and of African sculpture is apparent in its fragmented forms and unprecedented distortions. The painting heralded the first phase of cubism, called analytic cubism.
