One roped in emperor (4)

I believe the answer is:

nero

'emperor' is the definition.
(Roman emperor)

'one roped in' is the wordplay.
'in' indicates a hidden word.
'NERO' can be found hidden inside 'one roped'.

(Other definitions for nero that I've seen before include "Emperor said to have started the fire that destroyed Rome" , "Roman emperor who fiddled while Rome burned" , "Emperor (who fiddled while Rome burned?) d. AD68" , "Roman tyrant" , "Roman emperor on the fiddle?" .)
