If you've read The Hobbit, you know that one of the most attractive aspects of the story is the protagonist, Bilbo Baggins. He is eminently familiar as an example of perfectly average humanity: he loves food and comfort, he tries to avoid danger, and for the most part, he behaves exactly as we might expect any average person to behave. Bilbo's behavior is one of the most obvious ways that Tolkien ensures his faery story remains focused on humanity.
This is, perhaps, not the case for the heroes we've in The Silmarillion. In our encounters with Feanor and his sons, or with Thingol, Turgon, Barahir, Beren, Luthien, Turin, and Isildur, we meet characters who are bigger than life in almost every way. How, then, does Tolkien manage to maintain a focus on humanity in a way that is recognizable? Is it possible to identify with these heroes in a meaningful way? And if the heroes don't invite our identification with them, how do we make any meaning out of the mass of myth and legend presented in The Silmarillion?
