New from the world of literature: Michael Ward has detected the organizing principle behind the Narnia books by C.S. Lewis: each of the seven books evokes the mood of one of the seven medieval heavens: Jupiter, Venus, Mercury, Sol, Luna, Mars, and Saturn. At first glance it makes sense. That’s why the Christian theme is a minor one and why there’s a Father Christmas but no Nativity.
He has two books that analyze the parallels between medieval cosmology and the seven volumes. There’s a more scholarly critique called Planet Narnia and a more popular book called The Narnia Code. They came out a couple of years ago so you may have heard of them. You can read about them at Planet Narnia.
Hat tip to Jeffrey D. Koonistra, the book reviewer at Analog. He gets a point deducted, though for referring to representative people of their day as Medieval Man and Twenty-first-Century Man.
