What was the title of C.S. Lewis’s 1936 study of medieval allegory?

C.S. Lewis’s 1936 study of medieval allegory was titled The Allegory of Love: A Study in Medieval Tradition.

The book examines the development of allegorical love literature from classical and medieval sources. Lewis discusses how writers represented love as a literary and intellectual subject, with particular attention to medieval conventions and the tradition of courtly love.

The work helped establish Lewis’s academic reputation as a literary scholar before his best-known popular Christian writings and Narnia novels. It should not be confused with The Discarded Image, his later study of the medieval and Renaissance worldview, or with A Preface to Paradise Lost, his 1942 book on John Milton’s epic.
