The oxhide story which explains the name of the hill is most likely of Greek origin since "Byrsa" means "oxhide" in Greek, not in Punic. The name of the hill in Punic was probably just a derivation from Semitic "brt" "fortified place". But that does not prevent other details in the story from being Carthaginian, albeit still not necessarily historical. Michael Grant in "Roman Myths" (1973) claims that "Dido-Elissa was originally a goddess", and that she was converted from a goddess into a mortal (if still legendary) queen sometime in the later fifth century BCE by a Greek writer.
