Campbell held that numerous myths from disparate times and regions share fundamental structures and stages, which he summarized in The Hero with a Thousand Faces:
A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from this mysterious adventure with the power to bestow boons on his fellow man.[3]
Campbell and other scholars, such as Erich Neumann, describe narratives of Gautama Buddha, Moses, and Christ in terms of the monomyth[citation needed] and Campbell argues that classic myths from many cultures follow this basic pattern.
In a monomyth, the hero begins in the ordinary world, and receives a call to enter an unknown world of strange powers and events. The hero who accepts the call to enter this strange world must face tasks and trials, either alone or with assistance. In the most intense versions of the narrative, the hero must survive a severe challenge, often with help. If the hero survives, he may achieve a great gift or "boon." The hero must then decide whether to return to the ordinary world with this boon. If the hero does decide to return, he or she often faces challenges on the return journey. If the hero returns successfully, the boon or gift may be used to improve the world. The stories of Osiris, Prometheus, Moses, Gautama Buddha, and Jesus, for example, follow this structure closely.[1]
Campbell describes 17 stages or steps along this journey. Very few myths contain all 17 stages—some myths contain many of the stages, while others contain only a few; some
