“I paint objects as I think them, not as I see them.” – Pablo Picasso
“The Cubist painters rejected the inherited concept that art should copy nature, or that they should adopt the traditional techniques of perspective, modeling, and foreshortening. They wanted instead to emphasize the two-dimensionality of the canvas. So they reduced and fractured objects into geometric forms, and then realigned these within a shallow, relieflike space. They also used multiple or contrasting vantage points.” Quote from the Heilbrunn Timeline of Art History.
