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.

The Song of Songs, also called the Canticle of Canticles or the Song of Solomon, is an erotic poem, one of the five megillot ("scrolls") in the Ketuvim ('writings'), the last section of the Tanakh. It is unique within the Hebrew Bible: it shows no interest in Law or Covenant or the God of Israel, nor does it teach or explore wisdom, like Proverbs or Ecclesiastes—although it does have some affinities to wisdom literature, as the ascription to the 10th-century BCE King of Israel Solomon indicates. Instead, it celebrates sexual love, giving "the voices of two lovers, praising each other, yearning for each other, proffering invitations to enjoy".
