Final answer:
Pablo Picasso's 'Les Demoiselles d'Avignon' is a cornerstone artwork that bridges his African-influenced phase and the early development of Cubism, influenced by African art and Cézanne's formal ideas.
Step-by-step explanation:
The subject of Pablo Picasso's painting, Les Demoiselles d'Avignon, 1907 is not solely encompassed by one particular art movement but is considered a pivotal piece bridging his African influenced phase and the emergence of Cubism. The painting introduces radical formal fragmentation that foreshadows the Cubist movement but is actually a result of several influences. These include African art's impact on Picasso after visiting the ethnographic museum at Palais du Trocadéro and the formal ideas developed by Cézanne.
Moreover, Picasso's work is often tied to the concept of Primitivism, a term that encapsulates the western art movement's interest in the visual aesthetics of non-Western art. While the figures in Les Demoiselles d'Avignon show primitivist influence, particularly the two on the right side of the composition, what is depicted in the painting relates more closely to the foundational ideas leading up to Analytic Cubism rather than Fauvism, Surrealism, or Impressionism.
