Ancient storyteller (5)
I believe the answer is:
aesop
'ancient storyteller' 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 "Classic fable writer" , "Greek fable writer" , "A pose by Greek writer of fables" , "A pose of famed fable teller" , "Author of many fables" .)
