Carthaginian queen (4)
I believe the answer is:
dido
'carthaginian queen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dido that I've seen before include "Classical suicide" , "In Roman mythology, she committed suicide when abandoned by Aeneas" , "Antic" , "Legendary queen of Carthage" , "Mythological queen" .)
