Shakespeare's Athenian (5)
I believe the answer is:
timon
'shakespeare's athenian' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for timon that I've seen before include "Shakespearean Athenian" , "lead in Greek tragedy?" , "title role" , "- - of Athens (Shakespeare)" , "Shakespeare's Athenian" .)
