Writer of many fables (5)
I believe the answer is:
aesop
'writer of many fables' 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 "So ape the writer of fables" , "Greek teller of animal tales with a moral" , "Ancient Greek fabulist" , "A pose by Greek writer of fables" , "his writings were fabulous" .)
