I shunned such easily translated ancient Greek (9)
I believe the answer is:
aeschylus
'ancient greek' is the definition.
(ancient Greek dramatist)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for aeschylus that I've seen before include "Greek tragedian (Oresteia)" , "Ancient Greek dramatist (Oresteia trilogy)" , "Classical Greek playwright" , "classical author" , "play?" .)
