At
this period, Picasso started to look at the world in a different
perspective. When painting, he simplified his subjects into geometric
shapes. Instead of drawing a three dimensional object, Picasso
flattened the object (like how the world map is flat in text books).
Although these shapes seem flat, Picasso left some shading on the
individual shapes to help give them some dimension. Most of his
Analytical Cubist paintings are done in a brown or earth-color monotone
(one color).
