Cribro aquam haurire
Cribro aquam haurire To draw water with a sieve. To labor at what cannot, by its nature, come to anything.
Somewhere below the world, fifty sisters are walking to the river. Each carries a jar; each jar is pierced; each fills it anyway, walks it back, and finds it empty at the journey’s end, and turns around. Ovid, watching them through Juno’s eyes in the underworld, needed only five words for the whole economy of their punishment: quas perdant, Belides undas — the daughters of Belus, fetching forever the water they lose. The Greeks and Romans kept several images of hopeless labor in stock, but this is the one they reached for most instinctively, and when Erasmus came to catalogue the ancient proverbs he gave it its plainest working form: cribro aquam haurire. To draw water with a sieve.
What it means
The Latin is a bare infinitive phrase, and that is part of its usefulness: it is not a sentence but a description waiting to be aimed. Said of a task — this is drawing water with a sieve — it declares the whole undertaking void from the start. Said to a person, in the second person Erasmus also records — cribro aquam hauris, “you are drawing water with a sieve” — it is a diagnosis, and not a kind one. You are not failing at the work. The work was never capable of succeeding, because the tool you are doing it with is designed, down to its every hole, to release what you put into it.
Erasmus filed the adage in his great collection under the heading Inanis opera — vain labors — beside its Greek original, Κοσκίνῳ ὕδωρ ἀντλεῖς, “you are drawing water with a sieve.” The category is exact. This is not the futility of laziness, nor of bad luck, nor of insufficient strength. It is structural futility: the failure is woven into the mesh.
Where it comes from
The image is Greek before it is Latin, and it is a punishment before it is a proverb. In Plato’s Gorgias, Socrates retells an allegory he credits to “some clever man, a Sicilian perhaps” — in Hades, the souls of the foolish carry water to a pierced jar, using a sieve just as pierced; and the sieve, Socrates says, is the soul, leaky “because of unbelief and forgetfulness,” unable to hold anything it is given. The proverb’s whole later career is folded into that sentence: the leak was never in the basket. It was in the carrier.
The myth the tradition attached to the image is that of the Danaids: the fifty daughters of Danaus who, on their father’s orders, murdered their bridegrooms on the wedding night, and whose eternity — in the version Ovid, Horace, and the whole later tradition inherited — is spent hauling water in vessels that cannot fill. Rome kept a counter-image, too, and it is the stranger of the two: the Vestal Tuccia, accused of breaking her vows, who appealed to her goddess and carried a sieveful of Tiber water through the city without spilling a drop. Valerius Maximus records her prayer. The sieve that holds is a miracle; that is precisely how everyone knew what the sieve that leaks means.
From Erasmus’s Adagia — the 1508 bestseller that put three thousand classical tags into every educated European’s pocket — the sieve spread into the schoolrooms and the vernaculars, and “to carry water in a sieve” turns up in English proverb collections from the sixteenth century onward.
How it gets used today
Latin has no native speakers left to overhear, so the adage lives now in two registers, both documented rather than conversational. There is the learned tag itself, still quoted where classical furniture is at home — essays, sermons, courtrooms — usually of bureaucratic or Sisyphean assignments, work poured into institutions that cannot retain it. And there are its vernacular children, which do the daily labor: the English sieve-carrier, the Russian fool-teacher, the whole European family of leaking vessels. This is the kind of situation the phrase fits, rather than a scene anyone can be caught saying it in — a distinction the adage itself would appreciate.
Cousins from other tongues
Every language that has carried water has noticed that some vessels will not keep it. What differs — and it differs beautifully — is where each tradition decides the leak really is.
Mandarin puts the leak in the tool, and makes the tool a choice. 竹篮打水一场空 — zhú lán dǎ shuǐ yī chǎng kōng, “drawing water with a bamboo basket: a whole scene of emptiness” — is the sieve’s closest living cousin, and the two differ in exactly one respect: consent. The Chinese carrier picked up the basket; he can also put it down, and the proverb is spoken to help him put it down. The Danaids were issued their jars as a sentence and forbidden to stop. The same water falls through the same holes, and in one language it is a correctable folly, in the other a damnation. The distance between the two is the distance between a mistake and a fate.
Russian moves the leak out of the vessel altogether and into a head. Dal’ records the folk form Дурака учить — решетом воду носить — duraka uchit’ — reshetom vodu nosit’, “teaching a fool is carrying water in a sieve.” What was cosmology in Plato is pedagogy in the Russian village, and yet the two land on the same spot with uncanny precision: Socrates’ sieve-soul leaks “because of unbelief and forgetfulness,” and the Russian fool leaks lessons for exactly those reasons. Whether the image walked from Greece to Russia or arose twice on its own is not decidable from the sources; what is Russian about the Russian version is the aim. It is not a meditation on futility. It is a warning to the teacher: your bucket is fine, your water is fine, and you are pouring it into him.
Vietnamese refuses the leak entirely — and gets to the same emptiness by another road. Dã tràng xe cát biển Đông, nhọc nhằn mà chẳng nên công cán gì — “the sand crab rolls its sand in the Eastern Sea; such toil, and nothing comes of it.” The dã tràng, the little sand-bubbler crab, really does spend the low tide rolling thousands of perfect pellets of sand, and the tide really does come in. Here the vessel holds; the work completes; each ball of sand is finished and real — and then the sea takes it, wave by wave, the way the well took back the bamboo basket’s water. Behind the couplet sits a folk legend of loss: Dã Tràng was a man robbed of a magic pearl, who carted sand to fill the sea and get it back, and was turned into the crab still trying. The Latin sieve blames the tool and the Russian sieve blames the fool; the Vietnamese crab is blameless, diligent, even skillful. What defeats him is simply the size of the world’s undoing. It is the gentlest of the three, and the saddest.
Why it matters
The sieve has survived twenty-five centuries because it holds a distinction most languages need daily and cannot say quickly: the difference between work that fails and work that cannot succeed. Effort is not the variable — the Danaids are tireless, the fool’s teacher patient, the crab exact. Each proverb is a tool for telling someone, before the walk back from the river, which kind of task they are holding.
Rome, which invented very little of this, contributed the one image nobody else thought to keep: the sieve that held. Tuccia walked hers through the city full, once, because she asked it to prove something other than the water.
