Le Roman de la Rose is a medieval poem written in Old French and presented as an allegorical dream vision. As poetry, The Romance of the Rose is a notable instance of courtly literature, purporting to provide a "mirror of love" in which the whole art of romantic love is disclosed. Its two authors conceived it as a psychological allegory; throughout the Lover's quest, the word Rose is used both as the name of the titular lady and as an abstract symbol of female sexuality. The names of the other characters function both as personal names and as metonyms illustrating the different factors that lead to and constitute a love affair. Its long-lasting influence is evident in the number of surviving manuscripts of the work, in the many translations and imitations it inspired, and in the praise and controversy it inspired.

A dream vision or visio is a literary device in which a dream or vision is recounted as having revealed knowledge or a truth that is not available to the dreamer or visionary in a normal waking state. While dreams occur frequently throughout the history of literature, visionary literature as a genre began to flourish suddenly, and is especially characteristic in early medieval Europe. In both its ancient and medieval form, the dream vision is often felt to be of divine origin. The genre reemerged in the era of Romanticism, when dreams were regarded as creative gateways to imaginative possibilities beyond rational calculation.
