For example the angle of the prismatic shape (a knife) in the upper right hand side is at odds with the lemon it cuts into, and the various planes in the goblet indicate we are seeing its various angles all at once, a strong contrast to the linear perspective used in conventional works such as Pierro Della Franscesca's Ideal City where all lines converge on single vanishing point. Like Cezanne, the Cubists argued that a single perspective meant that one was not fully conscious of the whole object and did not correspond with the act of 'seeing' in reality.
