Calandrino—Bruno
The DecameronCalandrino—Bruno is a comic relationship built on asymmetry: Bruno understands how easily Calandrino can be led, while Calandrino repeatedly mistakes a coordinated prank for genuine illness or desire. In the episodes shown, Bruno turns Calandrino’s fears and romantic self-importance into opportunities for amusement and material gain, drawing others into the schemes and leaving his target unable to recognize the performance around him.
A friendship used for practical jokes
Bruno is not acting alone when he deceives Calandrino. In one episode, he joins Buffalmacco and the painter Nello in a plan to make Calandrino believe that he is seriously unwell. The immediate motive is pointedly practical: Calandrino has inherited two hundred crowns in small coin, talks as though he can buy an estate, and has refused to treat his companions to a meal. Bruno and Buffalmacco have already urged him to spend the money enjoying himself with them; when he does not, they decide to find another way to get something from him.
The prank depends on each participant supplying a small confirmation. Nello stops Calandrino in the street, studies his face, and suggests that he looks changed. Buffalmacco then accosts him and says that he appears half dead. When Bruno joins them, he repeats the concern, making it seem that several independent observers have noticed the same alarming change. Calandrino, who had felt no illness before the warnings began, starts to believe them precisely because the group presents a shared story rather than a single accusation.
Bruno gives the deception a practical direction by recommending that Calandrino go home, take to bed, and send his urine to Master Simone, the physician. He offers to find out what the doctor says and accompanies the scheme as it moves from the street into Calandrino’s household. By the time Master Simone examines the urine, Bruno has already told him what to do. The diagnosis that Calandrino is pregnant converts the supposed illness into an absurd predicament; Calandrino cries out in distress and blames his wife, Tessa. Bruno’s role is thus more than that of a bystander enjoying a joke: he helps manufacture the symptoms, directs Calandrino toward the planted authority who will confirm them, and makes the deception seem like medical care.
Bruno turns credulity into a courtship plot
In another episode, Bruno takes advantage of Calandrino’s vanity rather than his fear. Calandrino sees Niccolosa, Filippo’s wife, in the courtyard when she comes out to wash at the well. Her glances and sighs are meant to amuse her, not to invite him; Calandrino nevertheless interprets them as signs that she has fallen in love with him. He tells Bruno that he needs help and claims that Niccolosa is passionately enamoured of him, even though he has only just seen her.
Bruno knows who Niccolosa is and understands that Calandrino has mistaken deliberate teasing for genuine interest. Instead of correcting him, he promises to manage the affair. He tells Calandrino that he will discover the woman’s identity, then privately informs Nello and Buffalmacco of the infatuation. Bruno also speaks with Filippo and Niccolosa, arranging for them to play along so that the group can enjoy Calandrino’s antics. The joke therefore rests on a division of knowledge: Calandrino believes himself to be pursuing a secret passion, while Bruno and the other participants know that the supposed courtship has been staged for his benefit.
Bruno helps sustain Calandrino’s illusion with invented assurances. He reports that Niccolosa responds to Calandrino’s attentions and that discretion is essential because Filippo must not discover them. Calandrino offers to provide her with a thousand measures of a substance that gets women with child and declares himself ready to serve her. At supper, Niccolosa encourages his hopes while Filippo pretends not to notice. Bruno watches the performance and later proposes a way to make the affair proceed, keeping Calandrino’s confidence alive rather than allowing the misunderstanding to collapse.
Gifts, a counterfeit charm, and the intended meeting
The deception lasts for about two months. Bruno and Buffalmacco take advantage of Calandrino’s belief that he has a mistress by having him provide gifts and refreshments. At Niccolosa’s supposed request, he gives such objects as an ivory comb, a purse, and a knife. In return, he receives worthless counterfeit rings, which he accepts with delight. The exchange turns his imagined romance into a sustained source of dinners and small luxuries for the conspirators, while Bruno’s continuing attention makes Calandrino think that progress is being made.
As the work draws toward its end, Calandrino presses Bruno to bring the affair to a conclusion. Bruno first says that Niccolosa has promised repeatedly to grant his desire but has done nothing, then offers to make her comply whether she wishes it or not. Calandrino agrees. Bruno supplies the next device: Calandrino must bring him a piece of virgin parchment, a live bat, three grains of frankincense, and a candle blessed by a priest. Bruno writes invented characters on the parchment and presents it as a charm that will make Niccolosa follow Calandrino and do as he wishes if he touches her with it.
Bruno instructs Calandrino to find an opportunity to approach Niccolosa and then go to a nearby barn, which he describes as a suitably private place. Calandrino catches a bat during the night and delivers it, with the other requested materials, so Bruno can prepare the charm. These concrete errands deepen the deception: Calandrino does not merely believe Bruno’s claims but performs labor and gathers ritual objects to help bring about the encounter he imagines has been promised.
A relationship sustained by unequal knowledge
Bruno’s conduct in these episodes repeatedly combines attention with exploitation. He stays close enough to Calandrino to direct him, interpret events for him, and offer solutions, but that apparent assistance serves the practical jokes. In the illness episode, he channels fear toward a false medical diagnosis; in the courtship episode, he channels vanity toward counterfeit tokens, gifts, and a fabricated spell. The methods differ, but in each case Calandrino’s confidence in Bruno helps the deception advance.
The courtship plot also draws on the earlier history between Calandrino and Tessa. Nello reminds Tessa of the beating she received after Calandrino returned from the Mugnone laden with stones, and tells her that Calandrino is arranging a meeting with another woman. Thus a prank that Bruno helps organize reaches beyond the two men: it brings Calandrino’s wife into the planned exposure, while Nello’s warning turns her into another participant. The supplied episode breaks off as Tessa reacts to the news, so it establishes the setup for confrontation without showing its outcome.
Across the surviving details, Bruno is both conspirator and confidant, but not a trustworthy friend in the ordinary sense. His intimacy with Calandrino gives him the means to recognize what will persuade him; his wit is directed toward sustaining Calandrino’s mistakes rather than correcting them. The relation’s comic force comes from that imbalance: Bruno and his companions can see the machinery of the prank, while Calandrino treats each arranged sign as fresh proof that his fears or desires are real.
