Focus on The Empire of Light and explain the abstract.
The Empire of Light (French: L'Empire des lumières) is the title of a succession of paintings by René Magritte. They depict the paradoxical image of a nocturnal landscape beneath a sunlit sky. He explored the theme in 27 paintings (17 oil paintings and 10 gouaches) from the 1940s to the 1960s. The paintings were not planned as a formal series. They have never all been exhibited together and are rarely exhibited in smaller groups. The original French title, L'Empire des Lumieres is sometimes translated as singular, The Empire of Light,: 60 p. : 184 p. and sometimes as plural The Empire of Lights.: 126 p. : 177 p.   Other translations include The Dominion of Light: making the distinction: "an empire exists in relation to a ruler, a dominion does not necessarily require this.”
