"Vincent... had come to Paris in the Spring of 1886 to live with his brother Theo and to acquaint himself with all the new art movements. ...[H]e felt a growing desire to see the paintings by the impressionists of which Theo spoke so often in letters. He also began to be preoccupied by the problems of simultaneous contrast and complementaries, which formed the basis of Seurat's theories. ...Theo took it upon himself to introduce his brother to the painters with whom he had dealings."
