Famed fabulist (5)
I believe the answer is:
aesop
'famed fabulist' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aesop that I've seen before include "Greek storyteller" , "Author of many fables" , "Fabulous man" , "A classical fable teller" , "Greek fabulist (Tortoise and the Hare)" .)
