Marie-Thérèse VACOSSIN is an artist close to the Op art movement. She studied with Robert Lapoujade, who taught her to abandon the idea of representation and see beauty everywhere around her. Since then, she has seen the world as a repertoire of shapes, rhythms and color relationships. In 1973, under the influence of Jean Gorin and Ad Reinhardt (precursor of conceptual and minimal art), she made the transition to geometric abstraction, entirely focused on issues of color perception.
