"Parsifal” prop (5)
I believe the answer is:
grail
'parsifal prop' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for grail that I've seen before include "Round Table Knights sought the Holy ....." , "Fabled holy vessel" , "Holy vessel used at the Last Supper" , "Object of knightly quest" , "Holy object of search" .)
