In the masterpiece called Acrobat on a Ball you can note how this differs from his previous works. After 1904, Picasso started to paint using warm and delicate tones again, focusing his attention on less dark themes, marking the beginning of the pink period, that this painting belongs to. The representation of circus artists takes on allegorical meaning. The image is based on the contrast of the powerful figure of the athlete sitting on a huge cube and the delicate gymnast who tries to keep his balance on the moving ball.
