Man of morals (5)
I believe the answer is:
aesop
'man of morals' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aesop that I've seen before include "his writings were fabulous" , "classic author" , "Greek author of fables (c 620-560 BC)" , "A pose of famed fable teller" , "Fable-teller" .)
