"You only notice things if you stay in one place for a time," Hockney notes. While he is busy noticing everything he can in East Yorkshire he is also proving that even such a traditional genre as landscape painting is ripe for innovation and bold scale. Just as Richard Long and Andy Goldsworthy use the fabric of nature — mud, stones, water — to reconfigure the natural world, he is doing the same with paint. His strand of the landscape tradition is not that of Claude or Richard Wilson, who classicised what they saw, but a blown-up version of Edward Bawden and Eric Ravilious, who worked with the homely and found their subjects in nondescript corners of farmyards and hillsides. 

Of course the great looker in landscape painting was Constable, and Hockney is in the process of turning his own unregarded part of England into "Hockney country" as surely as Constable did with the Stour valley.
