Michael Ward discusses his belief that in CS Lewis's children's books about the magical land of Narnia there is a hidden system of medieval planetary symbolism.
Ward has said that this symbolism is a "genuine literary secret" which Lewis wove into his stories deliberately, and that therefore it is the key to understanding Lewis's Narnia.
This video is a clip from The Narnia Code, a documentary film made by Norman Stone for the BBC. The film examines the ideas in Michael Ward's book Planet Narnia, a theological investigation into CS Lewis, Narnia, and the seven heavens.
Ward has now written a more accessible version of Planet Narnia called The Narnia Code.
