Description Photograph near Flatford mill where John Constable painted many of his masterpieces.The Hay Wain is an oil on canvas painting by John Constable. It was finished in 1821 and shows a hay wain near Flatford Mill on the River Stour in Suffolk, though because the Stour forms the border of two counties, it depicts Willy Lott's Cottage in Suffolk on the left bank and the Essex landscape on the right bank..The Mill was owned by Constable's father, and the house on the left side belonged to a neighbour, Willy Lott (a tenant farmer), who was said to have been born in the house and never to have left it for more than four days in his lifetime. Willy Lott's Cottage has survived to this day practically unaltered, but none of the original trees in the painting exist today. The water level is also higher, as that area of East Anglia has sunk into the sea by one foot (30 cm) since Constable's time.The Hay Wain is revered today as one of the greatest British paintings, but, when it was originally exhibited at the Royal Academy in 1821 (under the title Landscape: Noon), it failed to find a buyer. It was considerably better received in France where it was praised by Thodore Gricault. The painting caused a sensation when it was exhibited with other works by Constable at the 1824 Paris Salon (it has been suggested that the inclusion of Constable's paintings in the exhibition were a tribute to Gricault, who died early that year). In that exhibition, The Hay Wain was singled out for a gold medal awarded by Charles X of France, a cast of which is incorporated into the picture's frame. The works by Constable in the exhibition inspired a new generation of French painters, including Eugne Delacroix.
