Queen of Carthage (4)
I believe the answer is:
dido
'queen of carthage' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dido that I've seen before include "Founding queen of Carthage (did next to nothing!)" , "Tragic queen" , "Antic" , "Lover of Aeneas" , "Carthaginian queen linked to Aeneas" .)
