Notes

  1. ^ Dido had believed that she and Aeneas shared a commitment, and yet he and the Trojans are preparing to leave Carthage. Translators Shadi Bartsch, Robert Fagles, Stanley Lombardo, Sarah Ruden, and David West supply the noun traitor. Frederick Ahl (Oxford, 2007) translates perfide as you perfidious cheat, and footnotes the irony that Ancient Romans reputed the Carthaginians as being perfidious.
