When seeking to evoke any type of myth, there is one very important aspect that should be borne in mind: myths tend to express absolute values. It’s the coherence of those values that can give myth its power, its ability to shape our world-view, at least in those moments when we’re immersed in a tale.
Two such absolute values in The Four Branches are honour and her reflection, shame: both motivate important events, ultimately shaping the actions of the characters. In the imagined world of the tales, such values are as hard and pervasive as any natural law.
Honour and shame compel different responses in The Four Branches: compassion in Rhiannon as she acknowledges her midwives’ shame; grief in Branwen for the tragic war that arose out of her shaming and subsequent attempts to restore her to honour. Likewise, over-sensitivity to honour and shame causes destructive fury in Efnysien, and a lack of sensitivity to the very same values causes a callous folly in Gwydion. These are all very varied responses to the constants of honour and shame.
If we take The Four Branches as our model, our tale should be founded upon similar absolute values. These absolutes will provide the true north of the mythic landscape, the direction by which all other directions are known. Absolutes point the way along the pilgrims path that characters either progress upon or are turned away from.
Fundamentally, these absolutes rest upon a sense of the sacred. They can only be absolute if they are treated as sacrosanct within the world-view of the tale. They can never truly be violated or undermined, only deferred or delayed. They exert a pull upon all who live in the tale’s imagined world, pervading the common understanding of the characters, their intuitions and behaviour.
Even though such absolutes are fundamentally impersonal in nature, they affect the personal lives of good and bad alike. Just as Lady Justice is blindfolded, these apparent ‘natural laws’ don’t see personal circumstance, they simply operate without discrimination. They are presented as perpetually imminent, woven into the fabric of a tale’s world, yet almost exclusively expressed through individual lives.
