After arriving in Paris in 1890, Jeanne Rij-Rousseau developed a salon that was seminal in the revolutionary development of modern art in the early 20th century. Her early interests focused on mathematics and the visual perception of sound waves—called Vibrisme—a set of ideas that led her to Cubism and to artist Juan Gris, whom she influenced. Rij-Rousseau’s circle also included Sérusier, Roussel, Vuillard, Maurice Denis, Signac, Braque, and Léger. Her Cubist construction of space is apparent in this whimsical and playful park view.
