Thanks to IO9 to sharing this explanation of Joseph Campbell’s idea of the hero’s journey, the set of standard features that recur in human storytelling, sometimes referred to as the monomyth. It actually does an impressive job of illustrating not just that there are recurring features, but also that myths, legends, and storytelling often switch up or combine the elements.
