The Symbolists are clustered on Level +2 and amongst them are the disconcerting paintings of Fernand Khnopff (1858-1921), a founding member of the Les XX art movement. Khnopff painted his sister, Marguerite, again and again, using her refined, almost plastic, beauty to stir a vague sense of passion - for she's desirable and utterly unobtainable in equal measure. His haunting Memories of Lawn Tennis is typical of his oeuvre, a work without narrative, a dream-like scene with each of the seven women bearing the likeness of Marguerite. In Caresses Marguerite pops up once more, this time with the body of a cheetah pawing sensually at an androgynous youth. Also exhibited here - and a real surprise - is Psyche's Wedding , a delightful painting by that forerunner of Art Nouveau, the Englishman Edward Burne-Jones (1833-98). Antoine Wiertz, who has a museum all to himself near the EU Parliament building, pops up too, his La Belle Rosme a typically disagreeable painting in which the woman concerned faces a skeleton.
