Discarded Things

The Discarded Image: An Introduction to Medieval and Renaissance Literature is a non-fiction book by C. S. Lewis. It was his last book and deals with medieval cosmology and the Ptolemaic universe. It portrays the medieval conception of a "model" of the world, which Lewis described as "the medieval synthesis itself, the whole organization of their theology, science and history into a single, complex, harmonious mental model of the universe."
