The word “viper” has served a dual purpose in literature—both as a literal reference to a venomous serpent and as a potent metaphor for treachery, malice, and deceit. In classical fables such as those by Aesop, the viper appears in its natural form, illustrating themes of danger and natural order ([1], [2], [3], [4]). Meanwhile, authors like Dickens, Chekhov, and Dumas employ the term metaphorically to denote a duplicitous character whose behavior is as dangerous and unpredictable as the snake itself ([5], [6], [7], [8], [9]). In these varied contexts, the imagery of the viper—its sting, its slippery nature, and its lethal presence—evokes both the literal and symbolic capacity to harm, betraying trust and corrupting bonds, whether it is the venomous bite that one must physically avoid or the insidious whisper of deceit that one must heed.
