Literature employs the term "concubine" to evoke multifaceted themes of social hierarchy, legal status, and personal agency. In religious and historical texts, the term is often used in structured, almost ritualistic contexts—for instance, as seen in discussions of marital customs in biblical translations ([1], [2], [3], [4], [5], [6]) and in theological debates by early Christian thinkers ([7], [8], [9]). At the same time, dramatic works and later narratives—ranging from Marlowe’s historical dramas ([10], [11], [12]) to the nuanced character portrayals in novels by Dostoyevsky ([13], [14]) and Hugo ([15], [16])—invoke "concubine" to underline power dynamics, scandal, and personal tragedy. This extensive usage highlights how the term not only marks legal and societal distinctions but also serves as a versatile symbol in exploring desire, disgrace, and the tensions between public duty and private passion.
