The artist’s most minimal work, White Doors (1905), is the cleverest of them all, I surely would have argued. The room is empty. A door opens in the middle of the picture, revealing a dark corridor, at the end of which there is another door, almost shut. On the right, a third door opens into the picture. We can’t see what’s behind it, and it obscures part of the room we are looking into. Thus, I would have said that Hammershøi, under the influence of post-structuralists, deconstructs painting by depicting the act of not seeing. But how wrong I would have been! If I had written something that pretentious, it surely would have been the last art review I ever wrote for the Evening Standard.
