Book excerpt: Superheroes have been an integral part of popular society for decades and have given rise to a collective mythology familiar in popular culture worldwide. Though scholars and fans have recognized and commented on this mythology, its structure has gone largely unexplored. This book provides a model and lexicon for identifying the superhero mythos. The author examines the myth in several narratives--including Buffy the Vampire Slayer, Green Arrow and Beowulf--and discusses such diverse characters as Batman, Wolverine, Invincible and John Constantine.
