What was the title of C.S. Lewis's 1936 book about medieval courtly love?

The Allegory of Love was C.S. Lewis's 1936 book about medieval courtly love.

Its full title is The Allegory of Love: A Study in Medieval Tradition. The book examines how medieval writers represented love through allegory, especially in works influenced by courtly-love conventions. Lewis discusses authors and texts including Ovid, Chrétien de Troyes, Guillaume de Lorris, John Gower, and Edmund Spenser.

The study established Lewis as a major literary scholar before his best-known Christian and fantasy books appeared. It was his first academic monograph and helped secure his reputation in medieval and Renaissance literature. The work is scholarly rather than a novel or an apologetic dialogue.

The title can be confused with Lewis’s later literary studies. The Discarded Image, published in 1964, explores the medieval and Renaissance world picture, while A Preface to Paradise Lost, published in 1960, focuses on Milton’s epic. Neither is the 1936 study of courtly love.
