Rene —, Belgian artist whose works include Elective Affinities and Golconda (8)
I believe the answer is:
magritte
(Other definitions for magritte that I've seen before include "RenZ -, Belgian artist" , "Belgian surrealist painter, d.1967" , "Belgian surrealist artist" , "Rene -, Surrealist painter" , "Belgian surreal painter" .)
