Cereals also offer wonderful pretexts for experimentation, such as Raoul Dufy's painting of the marine undulations of the fields. While in Langres, he painted a panorama of the eastern districts, between the blue stain of the Liez lake and the purplish glow of the setting sun. The artist translates the richly colored impressions of the colored landscape with broad brush strokes on wood, before noting the salient patterns with a quick, graphic brush. Thus the main visible monuments emerge from the undulating sea of wheat. In the foreground, the incongruous neighboring of a naked woman and a mechanical threshing machine make the painting tip over into a dreamlike dimension.
