Roman writer and orator (6)
I believe the answer is:
cicero
'roman writer and orator' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for cicero that I've seen before include "Old politician" , "One-time consul" , "Marcus Tullius -, Roman consul, orator and writer" , "Statesman from Rome" , "Philosopher" .)
