Paul Serusier met Gauguin at Pont-Aven in Brittany in 1888, and was deeply influenced by the ideas of Synthetism (Symbolism): Gauguin gave him one lesson - 'How do you see those trees? They are yellow? Well, paint them yellow. The shadow is bluish? Make it pure ultramarine ... Red leaves? Use vermilion.'
In Paris, Serusier was, with Denis, Bonnard and Vuillard, one of the founders of the Nabis. He visited Italy and Germany, and, in 1897, went to the Benedictine monastery at Beuron in Germany, where he was much influenced by their theories of religious art. His own A B C de la Peinture was first published in 1921.
There are works in London (Tate), Ottawa, Paris (Mus. d'Orsay), Stuggart and Warsaw.
