'Britannia' - Romans on TV?

[Alanus]

Very good point. On a totally different subject, I'm writing about three famous American rodmakers who were "lengendary." They existed, although stories about them were conflated. But "mythical," to me, means an entirely different connotation-- re: the person Never existed in real life. We see this with "King Arthur," a mythical personage, but certainly not a legendary one. By the way, where do these script writers get so-called "Celtic" nomens from? Why can't they use something realistic rather than making-it-up as they go along? But I suppose that would require research.
