The Great War, Magritte

Against a backdrop of a small wall and the smooth sky, very similar to the background of many other paintings by René, including "The Son of Man" and "The Art of Living". However, this time, the character is completely disconcerting.
What connection could the artist have found between this character and war? We must not forget that Magritte lived through both World Wars, so he knew exactly what he was doing by connecting them.
He wanted to portray her as an attractive lady with a hidden face, because war often seduces us, appearing to us as a kind of purification for a humanity often broken, worn down by envy and greed. The lady is beautiful, dressed in shining white, but we really cannot see her face. Perhaps the painter also seeks to allude to one of the darker sides of war, namely the riches that war generates for some businesses.
