Fable author (5)
I believe the answer is:
aesop
'fable author' 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 "Author of many fables" , "Greek teller of animal tales with a moral" , "his writings were fabulous" , "Fabulous writer" , "very old writer" .)
