What was C.S. Lewis's 1936 study of medieval and Renaissance literature called?

The Allegory of Love was C.S. Lewis's 1936 study of medieval and Renaissance literature. Its subtitle, A Study in Medieval Tradition, describes its examination of allegorical love poetry and the literary traditions surrounding it.

The book traces ideas about courtly love from classical and medieval sources into later English literature. Lewis discusses writers including Ovid, Chrétien de Troyes, and Edmund Spenser, showing how literary conventions developed across periods rather than appearing suddenly in one author.

The work helped establish Lewis's reputation as a serious literary scholar before his best-known popular and fictional books appeared. It also reflects his training in medieval and Renaissance literature, the field he taught at Oxford and later at Cambridge.

A Preface to Paradise Lost was a later critical work, published in 1960. The Discarded Image appeared in 1964, after Lewis's death, while English Literature in the Sixteenth Century was published in 1954.
