"The Treachery of Images" painter (8)
I believe the answer is:
magritte
'the treachery of images painter' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for magritte that I've seen before include "Belgian surrealist painter, d.1967" , "RenZ -, Belgian artist" , "Rene -, Surrealist painter" , "Belgian surrealist artist" , "Belgian surreal painter" .)
