Turner and Constable, two of Britain's most important painters, were also great rivals. Born one year apart from each other, they used landscape painting to interpret a changing world. J.M.W. Turner, who grew up in London in modest circumstances, quickly achieved success, while John Constable, the son of a wealthy Suffolk merchant, found recognition only later. Although they took different paths, both innovated landscape painting, with Turner favouring dramatic and luminous scenes and Constable seeking authenticity in nature. An exhibition celebrates the 250th anniversary of their birth, comparing works, sketches and personal objects to explore their artistic impact.
