(1888-1899) The art movement called Nabis was formed from a group of Paris artists. The group included Post-Impressionist illustrators and artists that played a big part in influencing the development of graphic art. The leader of the group was Paul Seriusier; he and the others were devoted to the work of Paul Gaughin and its color technique. They stressed putting a focus on design along with another art movement of the time called Art Nouveau. Key artists of Nabis included: Maurice Denis, Ker Xavier Roussel, Félix Vallotton, Pierre Bonnard, and Édouard Vuillard.
