Jean-François Millet
This picture is from a series depicting the four seasons commissioned in 1868 by the industrialist Frédéric Hartmann. Millet worked on the paintings intermittently for the next seven years. In Haystacks: Autumn, with the harvest finished, the gleaners have departed and the sheep are left to graze. Beyond the haystacks lie the plain of Chailly and the rooftops of Barbizon. The loose, sketch-like finish of this work is characteristic of Millet's late style: patches of the dark lilac-pink ground color are deliberately exposed, and the underdrawing is visible, particularly in the outlines of the haystacks and the sheep.
I'm a huge fan of painted haystacks and I find these ones very impressive. They look like UFOs!
P.S. And here are my absolutely favorite ones!
