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.

Hortus conclusus is a Latin term, meaning literally "enclosed garden". Both words in hortus conclusus refer linguistically to enclosure. It describes a type of garden that was enclosed as a practical concern, a major theme in the history of gardening, where walled gardens were and are common. The garden room is a similar feature, usually less fully enclosed.
