Emperor before the Year of the Four Emperors (4)

Ross

I believe the answer is:

nero

(Other definitions for nero that I've seen before include "Roman 9" , "Tyrannical Roman emperor" , "Emperor said to have fiddled as Rome burned" , "Emperor (who fiddled while Rome burned?) d. AD68" , "Emperor who played the fiddle" .)

I've seen this clue in The New York Times.
