Turpis Cupido refers to a morally corrupt desire or improper passion, often associated with obsessive or illicit love that leads to destructive behavior. In literature, this term is used to explore themes of unfulfilled longing and the consequences of allowing such passions to dictate one's actions. Within Vergil's Aeneid, particularly in the narrative involving Dido, Turpis Cupido emphasizes the darker aspects of love that can lead to tragic outcomes.
