What academic subject did C.S. Lewis teach at Cambridge after 1954?

After 1954, C.S. Lewis taught Medieval and Renaissance English at Cambridge.

In 1954, Lewis became the first holder of the newly established chair of Medieval and Renaissance English at Magdalene College, Cambridge. The appointment followed nearly three decades of teaching English at Oxford’s Magdalen College. His Cambridge work continued the literary and historical interests that had shaped both his scholarship and his fiction.

Lewis was an expert in medieval literature, Renaissance literature, allegory, and the history of English writing. His academic books include The Allegory of Love, published in 1936, and English Literature in the Sixteenth Century, published in 1954. His critical work helped establish his reputation independently of his popular religious and imaginative writing.

The college names can be confusing: Oxford has Magdalen College, while Cambridge has Magdalene College. The Cambridge chair was specifically in Medieval and Renaissance English, not theology, classics, or general literature.
