Most moviegoers attending the recent film "Don Juan De Marco" must have posed the question at least once: Who, in fact, was Don Juan?
It's one of those kinds of questions that pops up nearly every day, if you listen for it. It comes up in conversation, in a movie, on a television show or, especially, in a book or magazine. In Don Juan's case, it concerns a literary figure and whether that figure has a basis in fact or fiction.
But the question also can be broader. It can encompass a literary style, a specific novel, an author or favorite character, an era or school of thought.
