The grape-sharing pact between Lázaro de Tormes and the blind man turns a small act of almsgiving into a contest of appetite, suspicion, and inference. In Almorox at grape-harvest time, an unstable bunch makes ordinary saving impractical; the blind man proposes that they share it, then breaks his own rule and detects Lázaro’s more ambitious cheating from the boy’s silence. The meal ends not in fairness but in a demonstration of the blind man’s sharpness—and in Lázaro’s unwilling admiration for it.

Setting and Motive

The episode takes place in Almorox during the grape harvest, on the pair’s journey from Salamanca toward Toledo. The blind man has chosen the route because he expects Toledo’s people to be wealthier, although not especially generous with alms. Their travel is governed by the returns they find: they stay where hospitality and earnings are good, and move on after two or three days where they are not.

A grape-grower gives the blind man a bunch as alms. The fruit is very ripe, and the bunch is coming apart in his hands. Put into his bag, it would be crushed into must, along with anything it touched. Keeping it is therefore not a practical option. The blind man turns the gift into an immediate meal, presenting the decision partly as generosity toward Lázaro, whom he has that day filled with knee-blows and slaps. The offer carries both a material reason and a pointed contrast: the same master who has hurt the boy now invites him to share.

The Terms of the Pact

Seated on a low wall, the two agree to eat the bunch together, taking one grape each in turn. The blind man makes the condition explicit: neither is to take more than one at a time, and he says that following this method will prevent cheating. The arrangement depends not on dividing the fruit into equal portions, but on alternating bites under a shared rule.

That rule is broken almost immediately. On the second turn, the blind man starts taking two grapes at a time, assuming Lázaro is doing the same. Lázaro notices the breach and chooses not merely to match it but to outdo it, eating two or even three grapes at once, as many as he can manage. The pact thus becomes a tacit competition: each eats beyond the agreed measure, but only Lázaro escalates openly in response to the blind man’s first move.

Detection and Reversal

When the bunch is finished, the blind man is left holding its stem. Shaking his head, he accuses Lázaro of having eaten three grapes at a time. Lázaro denies it and asks why the blind man suspects him. The answer reverses the apparent advantage of the boy’s silence: the blind man says he knew because he himself had eaten two at a time and Lázaro had not protested.

The deduction depends on what Lázaro does not say. The blind man has not seen how many grapes the boy takes; instead, he reads the absence of an objection as evidence that Lázaro is taking still more. The same broken rule that gives Lázaro his opportunity also supplies the clue by which his master catches him. Their meal therefore tests more than obedience: it tests each man’s ability to infer the other’s conduct from a small change in behavior.

Relationship and Narrative Significance

The episode belongs to the early master–servant relationship between Lázaro and the blind man, already marked by punishment and the boy’s efforts to retaliate. Lázaro’s response to the grapes follows that pattern: he recognizes his master’s breach, then uses it to take more than his share. Yet the boy is not simply triumphant. He laughs inwardly and, although still a child, greatly admires the blind man’s extraordinary acuity.

That admiration gives the scene its double edge. The blind man’s “generosity” is limited to a meal prompted by fruit that cannot be stored, and his cleverness does not undo the violence he has inflicted on Lázaro. But in this small contest, he proves capable of turning the boy’s silence into a precise accusation. Lázaro’s recollection preserves both sides of the lesson: a rule can be exploited by the person who announces it, and the person who tries to profit from that breach may still be out-read. The incident makes their bond at once antagonistic and instructive, with the blind man’s perception winning the final turn.
