:::::::I would understand that you would distrust something that was really unprobable, but this case seems to me like a minor point is it really that improbable? I don't see this as a big issue at all. Also as I read the text direct translation simply means that translating something rather than naming it in that language let's say a place is called "Fehérvár" in a language meaning word for word White Tower. So if you direct translate a place into English you can call it WhiteTower from the translation of the Hungarian name but the phrase was used in let's say Lord of the Rings, The Two Towers doesn't mean anything regarding the name of the place that was translated. So in this sense that a phrase existed or not in 50BC and was used to describe other things like a fictional tower in a book as opposed to an actual city won't solve the matter.
