Delphi figure (6)
I believe the answer is:
oracle
'delphi figure' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oracle that I've seen before include "Prophesier" , "Place where ancient Greeks consulted a god or prophet" , "One successfully worked" , "(Prophecy given at) shrine" , "Expert" .)
