‘It seems to me that the confused mythology of Narnia is a feature, not a bug. Lewis is pulling in anything and everything that has meaning to him and patching it all together into some new myth. He and Tolkien were both interested in creating a new mythic story—it’s just that Tolkien was weaving his mythology from whole cloth, and Lewis was putting together a quilt, taking snatches of this or that mythology to make something that resonated with him as both new and true.
So, yes, he cuts out the sex from the fauns and the Bacchanalia, because that’s not the element of their mythology that he finds of interest. He tweaks Father Christmas so that he becomes a figure on par with the minor gods of Narnia. He ignores inconvenient plot points like the fact that food might be pretty hard to get in a country where it has been winter for years and years. He’s doing all this to move us toward the parts of the story that he finds most compelling: there is a broken world full of winter and traitors and evil creatures, but spring is coming…and we can be part of that heroic progression.
The underlying cohesion of Lewis’s world-building isn’t, like many of us might prefer, a watertight world with a central logic to it. That kind of world is for adults. Lewis’s world is a child’s world, where myths mix and overlap, where what is true and what is magical might be the same thing, where there is uncertainty when your sister says, “I found a fantasy world hidden in the furniture.”
In his essay “Myth Made Fact” Lewis explains the underlying rationale for why he would mash together any myth or symbol that rang true to him. He wrote, “… myth is the isthmus which connects the peninsular world of thought with the vast continent we really belong to. It is not, like truth, abstract; nor is it, like direct experience, bound to the particular.” Myth transcends thought, and Lewis believed that what resonated in, as he would say, “Pagan myth” was reality itself. Truth could be found in it, but to read a myth searching for truth would cause you to miss the point because you would lean into abstractions. One must experience the myth as story to have a concrete experience of the reality it represents.’
‘Lewis is not particularly interested in us knowing for sure that “Aslan equals Jesus.” He always plays it slant, and never once mentions Jesus by name. Lewis believed that myth prepares us for “true myth.” He loved the story of Balder, for instance, and believed that the love he had for that story, with the god’s death and resurrection, prepared him for the true and (by his estimation) historical myth of Jesus’s death and resurrection when he finally came to accept it. As he told his friend George Sayer, he wasn’t looking to convert people through Narnia so much as prepare them to meet Jesus in the real world. “I am aiming,” he said, “at a sort of pre-baptism of the child’s imagination.”’
