Two works by the 19th-century English painter JMW Turner are hung in room 15 of THE NATIONAL GALLERY, LONDON, with two by the 17th-century French landscape painter Claude, in accordance with Turner’s will.
When Turner died in 1851, he left to the National Gallery: "Dido building Carthage" (as shown below) and Sun rising through Vapour" on condition that they were hung ‘always between the two pictures painted by Claude’, which he named as 'The Seaport' and 'The Mill'.
Dido building at Carthage by Turner
The pictures within each pair are very different from one another in subject and mood. Turner may have deliberately chosen to make contrasting works so as to mirror the differences between the two pictures by Claude. By doing so, he could also perhaps avoid the sense that he was merely copying the earlier master’s work.
