Vincent in Paris
(Summer 1887)
 

Van Gogh, who "particularly admired a poem written by Walt Whitman about the beauty in a blade of grass", began painting waving stalks of wheat in Paris. In 1887, he made Wheat Field with a Lark where Impressionist influences are reflected in his use of color and management of light and shadow. Brush strokes are made to reflect the objects, like the stalks of wheat. The work reflects the motion of the wheat blowing in the wind, the lark flying and the clouds streaking from the currents in the sky.
