Derek Hyatt (1931–2015) maintained that he didn’t have a style, he had a subject. And the subject that had such a hold on him was the high moorland above Ilkely in Yorkshire. He was born there and discovered it slowly, its network of paths, streams and dry-stone walls, its geology and ancient rock carvings, its birds, animals, flowers, its weather, and he learned it in detail, as a child does, not with his eyes but with all of his senses. And what held the deepest fascination for him was not the spectacular or the sublime, but the story of the planet that is written onto the landscape: This was his subject as a painter.
