The Lung Symbol in Monstrilio: Analysis and Study Guide
What the Lung Is
In the opening chapter of Monstrilio, the lung is introduced as a literal anatomical fact: Santiago, the young son of Magos and Joseph, was born with a single lung. This is not metaphor—it is a congenital condition that shaped his life and, in Magos's understanding, defined his very being. The lung carried her son way past his expected life span, making it both the organ that sustained him and the organ that ultimately failed him.
Magos's identification of the lung as the core of his Santiagoness is the novel's central symbolic move. She considers other body parts—hair, fingers, toes, tongue, heart—and rejects each. Hair is too public and not a secret. Fingers and toes are familiar but not essential. The tongue is quick and lispy. The heart is quiet and solitary, engaged to both parents. Only the lung, the anomalous single lung, captures what made Santiago uniquely himself.
The Excision Scene
The excision itself is rendered with clinical precision and unsettling tenderness. Magos makes her first incision with the utmost care, lest Santiago wake up in a sudden rebirth. She finds the lung toward the right of his chest and describes it as lighter and more inconsequential than she thought it would be. This moment of anticlimax is significant: the organ that carried so much meaning is physically underwhelming. Yet Magos's determination does not waver.
She initially wants to rip the lung out entirely but decides instead to take only a nugget—the downmost tip—placing it in a clear jam jar her son used to keep pencils in. The jar is a mundane object, a container for school supplies, now repurposed as a reliquary. The choice of the tip, rather than the whole organ, suggests a desire to preserve rather than to possess entirely—though the distinction is blurred by the violence of the act itself.
How the Lung's Meaning Changes
The lung's symbolic weight shifts across the scene in several distinct ways:
From vital organ to relic. While Santiago was alive, the lung was the condition of his existence—the thing that kept him breathing, the anomaly that made him who he was. After death, it becomes a relic, an object of devotion that Magos can hold, taste, and keep.
From source of life to source of blame. Magos's feelings toward the lung are explicitly ambivalent: she wants to thank it, and also spit on it. The lung is both the reason Santiago lived as long as he did and the reason he died. It is simultaneously miracle and failure.
From Santiago's essence to Magos's possession. The lung begins as a part of Santiago—the core of his identity. By the end of the scene, it has become hers. She claims it, jars it, and takes it as her own. The lung is no longer Santiago's organ but Magos's object.
From private act to public rupture. The excision is performed alone, while Joseph rests in their bed. When he discovers what she has done, he says, You've destroyed him. For Joseph, the lung is part of his son's body, and its removal is a violation. For Magos, the lung is already Santiago's essence, and taking it is an act of preservation, not destruction. She reflects that she has destroyed nothing; nothing was left to destroy.
Character Connections
Magos is the agent of the excision and the primary interpreter of the lung's meaning. Her decision to take the lung is an act of ownership of the dead—a claim that her son is only hers now. The lung is the physical manifestation of her grief, a way of holding onto something that death has taken from her.
Joseph is the counterpoint. His grief is physical and immediate—he squeezes his son's body, nuzzles him, smells him. But he cannot comprehend Magos's act. His reaction, You've destroyed him, frames the lung as part of the body that should have been left intact. For Joseph, the body is the whole; for Magos, the lung is the essence.
Santiago is present only as a body, but the lung is his legacy. The novel's premise—that the lung piece will grow into the creature called Monstrilio—means that Santiago's identity is literally transplanted into a new form. The lung is the seed of what comes next.
Theme Connections
The lung symbol connects directly to several of the novel's central themes:
Grief as bodily instinct. Magos's grief is not abstract or intellectual. She licks her son's ear like an animal would, tastes his blood, and physically excavates his body. The lung is the culmination of this bodily grief—an act that treats mourning as something you do with your hands, not just your heart.
Imagined versus real death. Magos's fantasy of her son dying in a Mexico City mall, surrounded by an audience, contrasts sharply with the reality of his death in a secluded house. The lung excision is her attempt to impose meaning on a death that felt dull and undramatic. The lung is the meaning she creates.
The solitude of parental grief. Magos performs the excision alone, while Joseph rests. The act is a secret, a private ritual that cannot be shared. The lung is the object of her solitary grief—something only she can understand.
Preservation as defiance. By taking the lung, Magos defies the finality of death. The lung is preserved, kept, and—as the novel unfolds—cultivated into new life. The act of preservation is an act of refusal: a refusal to let Santiago be reduced to memory.
The Lung as Seed
The most significant transformation of the lung's meaning occurs after the excision. The piece of lung in the jam jar does not remain inert. It grows, changes, and eventually becomes the creature that gives the novel its title. This development retroactively redefines the lung: it is not merely a relic of Santiago but the seed of something new. The lung is both an ending and a beginning, a death and a birth.
This transformation also complicates Magos's act. Is the lung a preservation of Santiago or a replacement for him? The novel does not resolve this question, and the ambiguity is central to its power.
Study Questions
1. Why does Magos choose the lung specifically, rather than another body part?
Magos systematically rejects other body parts: hair is too public, fingers and toes are familiar but not essential, the tongue is quick and lispy, and the heart is quiet and solitary. The lung is the only organ that is uniquely Santiago's—the single lung that carried him past his expected lifespan. It is the anomaly that made him who he was, the core of his Santiagoness. The choice is not arbitrary; it is the result of a deliberate search for the essence of her son.
2. What does the jam jar symbolize?
The jam jar is a mundane object—a container for pencils, a school supply. Its repurposing as a reliquary is significant. It suggests that the sacred and the ordinary are not opposed but intertwined. The jar is also a container, and containment is central to Magos's project: she wants to hold onto Santiago, to keep him contained and present. The jar is the physical form of her refusal to let go.
3. How does Joseph's reaction to the excision differ from Magos's?
Joseph's reaction is immediate and visceral: You've destroyed him. For Joseph, the body is the whole, and the excision is a violation. For Magos, the lung is the essence, and the excision is a preservation. Their disagreement is not about facts but about what constitutes Santiago's identity. Joseph sees the body as the person; Magos sees the lung as the person. The scene dramatizes the solitude of parental grief—the way grief can isolate even those who mourn the same person.
4. How does the lung connect to the theme of imagined versus real death?
Magos's fantasy of her son's death in a Mexico City mall is theatrical and public—a death with an audience, a Pietà. The reality is dull and private. The lung excision is her attempt to impose meaning on a death that felt meaningless. By taking the lung, she creates a ritual, a story, a way of understanding what happened. The lung is the meaning she makes out of a death that refused to provide its own.
