I’ve studied more Latin than Greek, but I don’t believe that’s true.

Liddell and Scott give:
mythologia (in Greek letters): romance, fiction, legend, story-telling

Try a review of the work of Joseph Campbell. The myth can be legend or, in more modern parlance, reputation. It can easily be either true or false and still be myth.
