The word "perfidious" in literature has long been employed to evoke an intense sense of betrayal and treachery, coloring characters and events with a deep moral reprehension. In historical narratives and political discourses, for instance, it describes cruel and betraying figures—from tyrants and deceitful enemies in epic chronicles ([1], [2], [3]) to character assassins in political ruminations ([4], [5]). Authors also use it vividly in personal confrontations and dramatic exclamations, whether addressing a disloyal friend ([6], [7]), a seductive traitor ([8], [9]), or even as a playful metaphor for natural elements like the deceptive quiet of a river ([10]). Its adaptability is further evidenced in classical texts and modern satires alike, underpinning themes of loyalty and betrayal across genres from epic poetry to picaresque adventures ([11], [12], [13]).
