A revolutionary pose for an old story-teller (5)
I believe the answer is:
aesop
'old story-teller' is the definition.
'aesop' can be an answer for 'story-teller' (I've seen this before). I am unsure of the 'old' bit.
'a revolutionary pose for an' is the wordplay.
'a revolutionary' is a reversal indicator (letters revolve around).
'for' means one lot of letters go next to another (I've seen this in other clues).
'an' becomes 'a'.
'pose' reversed gives 'esop'.
'esop' after 'a' is 'AESOP'.
Can you help me to learn more?
(Other definitions for aesop that I've seen before include "Classic fable writer" , "Author of many fables" , "Fabulous man" , "Greek fabulist (Tortoise and the Hare)" , "very old writer" .)
