Mary-in-mourning sculpture (5)
I believe the answer is:
pieta
'mary-in-mourning sculpture' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pieta that I've seen before include "Statue of Mary and Jesus after the Crucifixion" , "mournful image" , "Devotional painting" , "Mary's portrait" , "religious picture?" .)
