What medieval literature subject did C.S. Lewis teach at Cambridge University?

At Cambridge University, C.S. Lewis taught Medieval and Renaissance literature.

Lewis became the first holder of the newly created chair of Medieval and Renaissance Literature at Magdalene College, Cambridge, in 1954. The appointment followed nearly three decades at Oxford, where he had been a fellow and tutor at Magdalen College.

His scholarship covered medieval allegory, romance, poetry, and literary history. Lewis’s academic interests also shaped his creative writing: his fiction frequently draws on medieval cosmology, chivalric romance, classical mythology, and Christian symbolism. His study The Allegory of Love, published in 1936, is one of the major works associated with his literary scholarship.

The Cambridge chair did not mean that Lewis was simply a historian of Christianity. His academic field was literature, and his teaching examined texts in their historical and imaginative contexts. He held the Cambridge post until his death in 1963, while continuing to publish essays, fiction, and religious writing.
