Soil – mud, even – shaped for sculpture (5,2,4)
I believe the answer is:
venus de milo
'sculpture' is the definition.
(I've seen this before)
'soil mud even shaped' is the wordplay.
'shaped' indicates anagramming the letters.
'soil'+'mud'+'even'='soilmudeven'
'soilmudeven' anagrammed gives 'VENUS DE MILO'.
'for' acts as a link.
(Other definitions for venus de milo that I've seen before include "Famous armless statue" , "Renowned sculpture in the Louvre" , "Ancient statue" , "Famous sculpture" , "topless work" .)
