Details 444 came from The Harvesters (1565) by Brueghel. Landscape art creates not only strange sights but impossible touch-sensations. It offers the tactile equivalent of a bird's-eye view: a giant's-hand-feel. It lets you imagine running your fingers over a terrain. As here. Brueghel makes the topside of the wheatfield into a surface asking to be smoothed and stroked. It's easy to feel this about real wheatfields - when far off. But on approach, the seeming smoothness breaks into separate scratchy ears. (Sheep are the same. Their fluffiness never survives close acquaintance). The picture's trick is to take a beguiling distance-effect and bring it near. It's in the Metropolitan Museum of Art, New York.
