Dear, good, kind, sacrificing Little Nell. Here she is kneeling by a wayside pond, bonnet pushed back, shoes and stockings off, while she rests her blistered feet. She scoops a palm of water with cupped hands and tenderly washes those of her grandfather: her feckless, gambling, on-the-lam grandfather. It is an old Oscar Wilde chestnut, but one would have to have a heart of stone to look at William Holman Hunt’s portrait of Charles Dickens’s saintly ‘Little Nell and her Grandfather’ (1845) without laughing.
