Pablo Picassos continued search for the essential features of perceived objects and his natural abidance to the general principles regulating artistic creation determined his intuitive analysis of the various stages of vision. His exploration of pictorial language is reflected in the wellestablished periods in the development of Cubism. Progressively objects were analyzed first by their image or retinal and surface or external features as viewed from particular observeroriented viewpoints during the PreCubist and Czannian Cubist stages then by viewerindependent structural features during Analytic Cubism and finally by categorial features during Synthetic Cubism. This final reevaluation allowed the artist to treat pictorial language as truly arbitrary leading to metaphorical correlations between objects that went beyond what was actually depicted on the surface of the canvas.
