"He [Delacroix] turns David upside down. His painting is iridescent. Seeing one Constable [famous English landscape painter, admired by French painters, then] is enough to make him understand all the possibilities of landscape, and he too sets up his easel by the sea.. .And he has a sense of human being, of life in movement, of warmth. Everything moves, every glistens. The light!.. .There is more warm light in this interior [probably: 'Woman of Algiers'] of his than in all of Corot's landscapes.."
