What was C.S. Lewis’s academic specialty at Oxford University?

C.S. Lewis’s academic specialty at Oxford University was English literature.

Lewis became a scholar and tutor in English literature at Oxford, where he taught at Magdalen College from 1925 until 1954. His academic interests included medieval and Renaissance literature, literary history, allegory, and the relationship between literature and religious imagination.

His scholarly work included The Allegory of Love, published in 1936, and English Literature in the Sixteenth Century, Excluding Drama, published in 1954. These books established him as a serious literary historian as well as a popular author.

Lewis later moved from Oxford to Cambridge, becoming the first holder of the chair of Medieval and Renaissance English at Cambridge University in 1954. His move did not change his field: English literature remained the central subject of his academic career.
