"The Tilled Field" painter Joan (4)
I believe the answer is:
miro
'the tilled field painter joan' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for miro that I've seen before include "He painted" , "Joan --, Spanish artist" , "Joan -, twentieth century Spanish surrealist painter" , "Catalan artist" .)
