Why is Cezanne called the father of modern painting?

Formalism believes that art is for art, and descriptive art is a vassal of literature, Roger? Frye thinks Cezanne is the "father of modernism" because his works are not dramatic and lyrical, but a process of simplification and reinforcement.

Cezanne's picture looks strange because he rebelled against the traditional single-point perspective and observed objects from multiple viewpoints. He attaches importance to structure, which is no longer a real three-dimensional space, but a decorative two-dimensional space. The space before and after is represented by the accumulation of pigments.

Why does his outline look so abrupt? He used block structure to express conflict and balance. It is often repeated on the shadow line, gradually making the outline round, muddy and thick.

In addition, he also attaches great importance to the use of complementary colors.

Roger? Frye put Cezanne on a theoretical hat, making him "the father of modern painting".
