Fabulist (5)
I believe the answer is:
aesop
'fabulist' is the definition.
(Greek composer of fables)
This is the entire clue.
(Other definitions for aesop that I've seen before include "fabulous figure?" , "So ape the writer of fables" , "Ancient Greek author of moral tales" , "Greek author, famous for his fables" , "Great Greek teller of animal fables" .)
