Cubism was one of the earliest styles of abstract or near-abstract art, developed around 1910 by Pablo Picasso, Georges Braque, and others. It presented objects — in this painting by Braque, a violin and a musical score — as intersecting geometrical forms (not only cubes!), as if viewed simultaneously from several perspectives. Interestingly, Braque does not treat the artist’s palette at the top in cubist fashion. Solomon R. Guggenheim Museum, New York, USA/Mondadori Portfolio/Walter Mori/The Bridgeman Art Library.
