Famed fable writer (5)
I believe the answer is:
aesop
'famed fable writer' 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 "Greek father of fables" , "Author of many fables" , "So ape the writer of fables" , "satirical writer" , "story teller" .)
