Triomphe rouge - Georges Mathieu. Mathieu was born in Boulogne-sur-Mer, France, and gained an international reputation in the 1950s as a leading Abstract Expressionist. His large paintings are created very rapidly and impulsively. Despite his unconventional technique, he considers himself an historical painter working with abstract subject matter. His paintings are related to American Lyrical Abstraction and to Art informel as well.
