Cubism is "the art of paintingnew compositions by means of elementstaken from attainable - rather than visual - reality"
Guillaume Apollinaire - Cubist Painter in "Action" no 3, April 1920

"The syntax of cubism has revolutionized the pictorial image. Its vocabulary of plastic signs has rshaped the modern vision, changed the focus of modern design, of modern poster art. Cubism became the formative instrument of our way of seeing, just as five hundred years ago the invention of scientific perspective formed the Renaissance way of seeing."
Pierre DAIX - Cubists and Cubism, 1982
