Les Nabis

Wikipedia - "Les Nabis (French pronunciation: ​[le nabi]) was a group of young French artists active in Paris from 1888 until 1900, who played a large part in the transition from impressionism and academic art to abstract art, symbolism and the other early movements of modernism. The members included Pierre Bonnard, Maurice Denis, Paul Ranson, Édouard Vuillard, Ker-Xavier Roussel, Félix Vallotton, and Paul Sérusier. Most were students at the Académie Julian in Paris in the late 1880s.

In 1900, the artists held their final exhibit, and went their separate ways. ..."
