The word “dolor” in literary works functions on multiple levels, often evoking both the tangible pangs of physical pain and the more abstract depths of emotional suffering. In certain texts, it straightforwardly designates bodily discomfort—ranging from headaches ([1], [2]) to stomach aches ([3], [4])—while in others it is imbued with a poetic quality that underscores the despair and melancholy of the human condition ([5], [6]). Authors employ “dolor” not only as a descriptor of personal anguish—as in the anguished laments of Dante ([7], [8], [9], [10]) and the reflective sorrow in lyrical verses ([11], [12])—but also as a symbol or even a proper name that characterizes individuals with tragic destinies, such as the recurrent figure of Prince Dolor ([13], [14], [15], [16]). This versatility allows “dolor” to resonate with readers across different eras and cultural contexts, affirming its enduring significance in literature.
