Medardo of Terralba serves as the central protagonist whose literal bisection by a cannonball creates the novella’s primary conflict and thematic exploration. Initially presented as a young man “in his first youth, the age in which confused feelings, not yet sifted, all rush into good and bad” (2), Medardo embodies natural human complexity before his violent division. His character functions as both the catalyst for the story’s events and the ultimate embodiment of Calvino’s argument for The Necessity of Moral Complexity for Human Wholeness.
The Bad ’Un represents the dangerous extremes of unchecked evil impulses. His actions demonstrate systematic cruelty through calculated violence, arson, and psychological manipulation. He establishes elaborate execution devices, condemns innocents to death, and derives pleasure from halving objects in nature, creating a pattern of destruction that mirrors his own incompleteness. His courtship of Pamela reveals the sterile nature of his emotions, as he coldly declares, “I have decided to fall in love with you” (56), treating human connection as another mechanism for domination. The Bad ’Un’s characterization illustrates how moral extremism creates not strength but a hollow, destructive force that ultimately consumes itself.
The Good ’Un embodies the opposite extreme, representing virtue taken to oppressive lengths. His compulsive need to help others becomes intrusive and judgmental, alienating the very people he seeks to aid. His interactions with the Huguenots reveal how excessive morality can become another form of tyranny, as he criticizes their business practices and disrupts their community harmony. Similarly, his presence among the residents of Pratofungo destroys their joyful culture by imposing rigid moral standards. The Good ’Un’s character demonstrates that purity of intention without recognition of human complexity leads to spiritual arrogance and social destruction.
The reunited Medardo achieves psychological wholeness through the integration of his opposing impulses. His final state represents neither perfect goodness nor reformed evil, but rather “a mixture of goodness and badness” that acknowledges the full spectrum of human nature (110). This transformation suggests that authentic identity emerges not through the elimination of moral complexity but through its conscious acceptance and integration. The Viscount’s character arc embodies the novella’s central argument that human completeness requires embracing rather than rejecting the contradictory elements within ourselves.
The unnamed narrator serves as both the story’s observational lens and a representation of coming of age in a fragmented world. As Medardo’s nephew, he occupies a liminal position within the social hierarchy, being “part of the Terralba family only by tardy recognition” yet belonging neither to servants nor to masters (28). This marginal status grants him unique access to different social strata while maintaining enough distance to observe objectively. His character functions as a guide through the moral complexity of the divided world, offering a perspective that remains curious and questioning rather than judgmental.
The narrator’s youth allows him to adapt to the strange new reality of his uncle’s division with remarkable resilience. His friendship with Dr. Trelawney reveals his intellectual curiosity and desire for understanding, as he accompanies the doctor on scientific expeditions and will-o’-the-wisp hunting. These adventures represent his search for meaning and knowledge in an incomprehensible world. His ability to maintain relationships with both halves of his uncle, despite their opposing natures, demonstrates a natural capacity for accepting moral complexity that the adult characters struggle to achieve.
As the story progresses, the narrator’s character development reflects the broader theme of Searching for Authentic Identity in a Fragmented World. His final reflection that “sometimes one who thinks himself incomplete is merely young” suggests that his sense of incompleteness stems from adolescent self-awareness rather than actual fragmentation (111). His growth throughout the narrative represents the natural process of integrating diverse experiences and perspectives into a cohesive sense of self, contrasting with the artificial division that afflicts his uncle.
Pamela functions as both the catalyst for the conflict between the two halves and a symbol of natural wholeness in the fragmented world. Her character offers earthly, practical wisdom that contrasts sharply with the extremes of both moral halves. As a “goat girl” who lives close to nature, she embodies organic completeness and serves as a foil to the artificial divisions that plague other characters. Her ability to immediately recognize the difference between Medardo’s two halves demonstrates an intuitive understanding of human nature.
Her romantic entanglement with both halves reveals the inadequacy of moral extremes in forming genuine human connections. With the Bad ’Un, she experiences fear and revulsion at his cold manipulation and violent intentions. With the Good ’Un, she finds his excessive virtue equally problematic, noting that he wants to “do good together” as the only way to love (78), which she recognizes as emotionally sterile. Her rejection of both extreme approaches to courtship reflects her understanding that authentic relationships require acceptance of human complexity rather than ideological purity.
Pamela’s final union with the reunited Medardo represents the successful integration of opposing forces within human nature. Her practical approach to the bizarre situation of having two suitors who are literally the same person demonstrates a pragmatic wisdom that accepts life’s contradictions without being overwhelmed by them. Her character embodies the possibility of wholeness through acceptance rather than through the elimination of complexity, making her essential to the story’s resolution and thematic coherence.
Dr. Trelawney serves as both a comic figure and the facilitator of the story’s resolution. His character represents the intersection of scientific inquiry and human compassion, though his approach to both reveals his significant limitations. As a former ship’s doctor who spent his voyages playing cards rather than observing the world, he embodies the theme of incompleteness through willful ignorance. His various obsessions with crickets, fossils, and will-o’-the-wisps demonstrate a scientific curiosity that remains safely detached from human suffering.
His relationship with the narrator provides the boy with a surrogate father figure while highlighting the adult world’s failures to provide proper guidance. Dr. Trelawney’s cowardice in the face of human illness and his fear of blood reveal his inability to confront the messy realities of human existence. His abandonment of Sebastiana during her false Hansen’s disease diagnosis demonstrates how intellectual pursuits can become an escape from moral responsibility. Yet his ultimate role in reuniting the two halves suggests that even flawed individuals can contribute to healing and wholeness when circumstances demand action.
The doctor’s character development reflects the broader theme of Searching for Authentic Identity in a Fragmented World rather than avoiding complexity. His final success in reuniting Medardo represents a moment of genuine engagement with human suffering that transcends his previous academic detachment. His departure with Captain Cook’s fleet suggests that his role as a catalyst for healing was temporary, but his impact on the community’s restoration remains permanent.
Sebastiana embodies maternal wisdom and represents the continuity of traditional values in a world of extremes. As the nurse who “had given milk to all the males of the Terralba family, gone to bed with all the older ones, and closed the eyes of all the dead ones” (19), she represents the cyclical nature of life and death that transcends individual moral crises. Her character serves as a stabilizing force that maintains human connections despite the chaos created by the Viscount’s division.
Her treatment by the Bad ’Un, who falsely diagnoses her with Hansen’s disease and sends her to Pratofungo, demonstrates how moral extremism destroys the very foundations of human community. Her survival in Pratofungo through practical knowledge of herbs and her ability to maintain her humanity while pretending to be afflicted reveal her resilience and adaptability. Her maternal criticism of both halves of Medardo, treating them as a single misbehaving child, shows an understanding of human nature that transcends intellectual analysis.
The Huguenots, led by Ezekiel, represent religious extremism and the dangers of moral rigidity. Their exile from France has stripped them of their religious texts and rituals, leaving them with only the memory of persecution and a desperate need to maintain their religious traditions. Their characterization demonstrates how the destructive nature of moral extremism can emerge from genuine suffering and sincere religious conviction. Their constant fear of making theological errors has reduced their faith to a series of prohibitions and suspicious glances.
Ezekiel’s character embodies the patriarchal authority that has been corrupted by extremism. His constant shouting of “[f]amine and plague” while demanding impossible standards of work and virtue reveals how moral absolutism becomes a form of tyranny (42). His son Esau’s rebellion against these standards provides a counterpoint that shows the natural human tendency to seek balance and moderation.
Pietrochiodo represents the conflict between artistic skill and moral purpose. His exceptional craftsmanship in creating execution devices reveals how technical excellence can serve immoral ends when divorced from ethical consideration. His character embodies the struggle between professional pride and moral responsibility, as he takes pleasure in the ingenuity of his creations while agonizing over their murderous purpose.
His inability to successfully create beneficial machines for the Good ’Un while easily constructing instruments of torture for the Bad ’Un suggests that destructive impulses may be more easily realized than constructive ones. His character illustrates the novella’s treatment of moral complexity by showing how individual talents can serve opposing purposes, depending on the moral framework within which they operate.
The people with Hansen’s disease who live in Pratofungo represent society’s outcasts, who have created their own alternative community based on acceptance of physical corruption and moral licentiousness. Their joyful lifestyle offers a stark contrast to the moral rigidity of other characters, suggesting that happiness may be possible even in difficult circumstances. Their rejection of both halves of Medardo for different reasons demonstrates an understanding that both extreme virtue and extreme vice are ultimately oppressive.
Their characterization challenges conventional moral categories by presenting characters who are physically ill but emotionally healthy, creating a complex moral landscape that resists simple judgments. Their community represents a form of wholeness achieved through acceptance of human imperfection rather than through the pursuit of impossible purity.
Galateo serves as a messenger figure who moves between the outside world and Pratofungo, representing the necessary connections between different social groups. His role as the collector of alms demonstrates how even outcasts maintain ties to the broader community through ritualized exchange. His function as the duel’s umpire shows how marginalized figures can serve as neutral arbiters in conflicts between opposing extremes.
Esau represents youthful rebellion against oppressive moral authority. His deliberate pursuit of sin as a reaction to his family’s rigid virtue demonstrates how moral extremism creates its own opposition. His character illustrates the natural human tendency to seek balance and the dangers of suppressing normal impulses through excessive moral control. His friendship with the narrator provides a model for how young people can resist the artificial divisions imposed by their elders.
