Robert Motherwell is a highly intellectual painter, known for his distinctive style in Abstract Expressionism. His works are imbued with an expression and rigor that reflect the human soul, while simultaneously addressing political and humanitarian issues. "Robert Motherwell: Pure Painting" is an in-depth examination of his artistic practice. Art leaders analyze the American artist's transition from Surrealism to abstraction and examine the major series he developed over a fifty-year career. The catalog studies the dialogue between Motherwell's art and the tradition of 19th-century French painting, explores his relationship with Spanish techniques and processes, emphasizing their fundamental political significance, and delves into Motherwell's use of ochre color, with its internalization in geological time and avant-garde practices.
