Definition of Style & Subject Matter:
Cubism was a highly influential visual arts style of the 20th century that was created principally by the painters Pablo Picasso and Georges Braque in Paris between 1907 and 1914. The Cubist style emphasized the flat, two-dimensional surface of the picture plane, rejecting the traditional techniques of perspective, foreshortening, modeling, and chiaroscuro and refuting time-honoured theories of art as the imitation of nature. Cubist painters were not bound to copying form, texture, colour, and space; instead, they presented a new reality in paintings that depicted radically fragmented objects, whose several sides were seen simultaneously.
Typical cubist paintings frequently show letters, musical instruments, bottles, pitchers, glasses, newspapers, still lifes, and the human face and figure.
