I prefer
Enea to
Aeneas, but since I'm not Italian it's a bit academic - I'd never use it. And anyway, I can't say I ever warmed up to
Aeneas, as
Virgil depicted him: no personality that I could ever detect! And trying to apologise to
Dido in the Underworld ... what a cheek. I'm so glad she didn't let him get away with it.
