Recently, I discussed how in The Discarded Image, C.S. Lewis elaborates on how Medieval cosmology exerted a profound creative influence on Medieval and Renaissance literature. Lewis worried that the creative aesthetic spark of this worldview had been lost in a utilitarian modern culture. It should not be a surprise that Lewis would incorporate elements of the Medieval worldview, which was both his academic specialty and passion, into his fantasy novels. Yet as Michael Ward points out in his book Planet Narnia, this aspect of Lewis’s work went unnoticed for decades and is only now beginning to be explored.
