Each of the mythologies we’ve examined thus far can be deconstructed into a common narrative of creation. Though we have not yet studied any other form of myth yet aside from creation stories, this is a common theme amongst most mythologies. Joseph Campbell developed a working model of the “monomyth”, or the archetypical storyline surrounding all common mythologies. If you’re not familiar with him but interested in a literary analysis of mythical narratives, I’d definitely recommend reading The Hero with a Thousand Faces. The monomyth essentially plots out the nature of this archetypical storyline (journey through an abyss -> transformation -> attainment of ultimate boon) alongside the archetypical characters: the naive hero, the guardian or seer, the trickster, etc. Jesus and The Bible is a pretty good example of this.
What the monomyth can tell us is that human being are effectively programmed to relate to an archetypical storyline in order to understand the world. Every myth did not coincidentally have these common roots. The human mind, regardless of cultural context, articulates things in the same way. Plus we just absolutely love stories and can’t help but interpreting our experience into them.
