From The National Museum of Western Art, Tokyo:
Picasso, who visited Rome in 1917, was greatly influenced by classical art. Strong outlines became very prominent in comparison to works from his period of cubism, which sought to resolve objects into their constituent shapes. It was the beginning of his so-called Neo-Classical period. Even in this sketch from 1920, there is a fullness and precision to the lines, and the figure of the model conveys an imposing sense of volume. (Source: The Digital Gallery. 1999-2006)
