The great German Romantic Caspar David Friedrich deserves more attention

Vanderlyn’s incendiary painting of British perfidy and indigenous brutality

At the time of his death, he had done more than Turner to show the possibilities of watercolour

At last, a truly world-class experience

The art establishment has revived competent drawing in spite of itself
